Slide 2: 070-291 QUESTION: 1 You work as the network administrator at Certmagic.com. The Certmagic.com network consists of a single Active Directory domain named Certmagic.com. All servers on the Certmagic.com network run Windows Server 2003 and all client computers run Windows XP Professional. The Certmagic.com network contains a print server named Certmagic-PR01 that has a built-in network interface. A Certmagic.com user named Andy Reid is a member of the Research and Development department. Andy Reid complains that he cannot print to a print device attached to Certmagic-PR01. You have received instruction to ensure that Andy Reid can print to the print device. First you verify that the IP address for Certmagic-PR01 is correct and that the latest drivers for the print device are installed. You now want to verify that the print jobs are being sent to the correct MAC address for Certmagic-PR01. What should do? A. On Certmagic-PR01, run the net session command. B. On Certmagic-PR01, run the netstat command. C. On Certmagic-PR01, run the netsh command. D. On Certmagic-PR01, run the netcap command. Answer: D Explanation: Netstcap.exe is a command line tool that could be used to capture the network traffic. A filter can be created to be used during the capture to determine the MAC address the print jobs are being sent to. The Network Monitor Capture Utility ( Netcap.exe) can be used to capture network traffic in Network Monitor. Netcap provides capture abilities only from a command prompt; to open the resulting capture (.cap) files, you must use the full Network Monitor interface. Netcap is installed when you install the Support tools that are on the Windows XP CD-ROM. Netcap provides capture abilities that are similar to the version of Network Monitor that is included with the Windows Server products; however, you must use Netcap at a command prompt. Netcap installs the Network Monitor driver and binds it to all adapters when you first run the Netcap command. Incorrect Options: A: The net session command can be used to view the computer names and user names of users on a server, to see if users have files open, and to see how long each user's session has been idle. Net session manages server computer connections - used without parameters, net session displays information about all sessions with the local computer. B: The netstat command is not a utility to use when troubleshooting NetBIOS names, but is used to display TCP/IP and port information. C: The Network Shell utility (Netsh.exe) can perform a wide range of system configuration tasks. You can use commands in the Netsh Interface IP context to configure the TCP/IP protocol (including addresses, default gateways, DNS servers, and WINS servers) and to display configuration and statistical information. 2 http://www.certmagic.com

The Certmagic.com network consists of two subnets. All servers on the Certmagic.com network run Windows Server 2003 and all client computers run Windows XP Professional. All servers are located in a central data center that uses a single IP subnet and all client computers are located in one subnet. The data center contains two routers named Certmagic-SR01 and Certmagic-SR02, two domain controllers named Certmagic-DC01 and CertmagicDC02, and two file servers named Certmagic-SR03 and Certmagic-SR04. The IP addresses of these servers are indicated in the table below. Host name CERTMAGIC-DC01 CERTMAGIC-DC02 CERTMAGIC-SR01 CERTMAGIC-SR02 CERTMAGIC-SR03 CERTMAGIC-SR04 IP address 10.10.10.1 10.10.10.2 10.10.1.1 10.10.1.2 10.10.11.1 10.10.11.2 You have received instruction from the CIO to install a new database server in the data center. You install Windows Server 2003 on a new server computer named CertmagicDB01 and hand it over to a database administrator named Dean Austin. Dean Austin installs Microsoft SQL Server 2005 and makes some changes to the TCP/IP settings on Certmagic-DB01 as shown in the following table. Parameter IP address Subnet mask Default gateway Value 10.10.1.3 255.255.255.0 10.10.1.2 Later, Dean Austin complains that Certmagic-DB01 cannot communicate with the other servers in the data center. All other servers in the data center can communicate with the other servers as well as the client computers. You log on to Certmagic-DB01 and attempt to ping Certmagic-DC01 but you receive the following error message: "Destination host unreachable". What should you do to ensure that Certmagic-DB01 can communicate with the other computers in the Certmagic.com network? 3 http://www.certmagic.com
Slide 4: 070-291 A. Configure Certmagic-DB01 with a default gateway of 10.10.1.1. B. Configure Certmagic-DB01 with a subnet mask of 255.255.0.0. C. Configure Certmagic-DB01 with an IP address of 10.10.10.3. D. Configure Certmagic-DB01 with an IP address of 10.10.11.3. Answer: B Explanation: Large networks are subdivided to create smaller subnetworks to reduce overall network traffic by keeping local traffic on the local subnet and sending all nonlocal traffic to the router. In order to create a subnetwork, we need to have a system for addressing that allows us to use the network ID and host ID within the class-based system. This is accomplished through the use of a subnet mask. To determine the appropriate custom subnet mask (typically referred to simply as subnet mask) for a network, you must first: 1. Determine the number of host bits to be used for subnetting. 2. Determine the new subnetted network IDs. 3. Determine the IP addresses for each new subnet. 4. Determine the appropriate subnet mask. Incorrect Answers: A: You need to assign the correct subnet mask to ensure connectivity. C, D: The problem in this scenario is not a faulty IP address. It is the appropriate subnet mask that has to be determined to enable connectivity. Reference: Deborah Littlejohn Shinder, Dr. Thomas W. Shinder, Chad Todd and Laura Hunter, MCSA/MCSE: Exam 70-291: Implementing, Managing, and Maintaining a Windows Server 2003 Network Infrastructure Guide & DVD Training System, p. 57 QUESTION: 3 You work as the network administrator at Certmagic.com. The Certmagic.com network consists of two subnets named Subnet A and Subnet B. Subnet A and Subnet B are connected by a router. All computers on the Certmagic.com network are configured with static IP addresses. All network servers run Windows Server 2003 and all client computers run Windows XP Professional. Certmagic.com hires a new Sales manager named Amy Wilson. You install a new client computer named Certmagic-WS291 for Amy Wilson. You then add Certmagic-WS291 to Subnet A. The relevant portion of the network is configured as shown in the exhibit. 4 http://www.certmagic.com
Slide 5: 070-291 However, Amy Wilson complains that Certmagic-WS291 cannot communicate with other hosts on the network. What should you do to ensure that Certmagic-WS291 can communicate with all local and remote computers on the Certmagic.com network? A. Configure Certmagic-WS291 with a default gateway of 192.168.28.84. B. Configure Certmagic-WS291 with a default gateway of 192.168.2.1. C. Configure Certmagic-WS291 with a subnet mask of 255.255.255.128. D. Configure Certmagic-WS291 with a subnet mask of 255.255.255.192. Answer: C Explanation: It is evident from the exhibit that the file server and Certmagic-WS291 have a different subnet mask. This is the reason why they cannot communicate with each other. You must therefore change the subnet mask of Certmagic-WS291 to 255.255.255.128. Incorrect Answers: A, B: The problem is not the gateway IP address that is faulty, but rather the subnet mask. D: This option suggests the correct object that has to be changed, but it gives the wrong subnet mask. Reference: Deborah Littlejohn Shinder, Dr. Thomas W.

Slide 6: 070-291 QUESTION: 4 You work as the network administrator at Certmagic.com. The Certmagic.com network consists of a single Active Directory domain named Certmagic.com. Certmagic.com has its headquarters in Chicago and branch offices in Dallas and Miami. All servers on the Certmagic.com network run Windows Server 2003 and all client computers run Windows XP Professional. You work in the Miami branch office. The network at the Miami branch office consists of 25 different subnets, each with a maximum of six computers. The network administrator at headquarters has allocated the 192.168.3.0/24 network address to the Miami branch office. You install a new server named Certmagic-SR21 in the Miami branch office. You need to configure the Internet Protocol (TCP/IP) properties for Certmagic-SR21. You configure Certmagic-SR21 with an IP address of 192.168.3.44. What subnet mask should you use? A. A subnet mask of 255.255.255.0. B. A subnet mask of 255.255.255.128. C. A subnet mask of 255.255.255.192. D. A subnet mask of 255.255.255.240. E. A subnet mask of 255.255.255.248. Answer: E Explanation: The network address is: 192.168.2.0/24, which means 11111111.11111111.11111111.0 in binary. Therefore, you can use the last octet to configure the 30 subnets and 6 hosts in each subnet You need only six host PCs. When you convert to binary, it is: 00000111. As a result, you use 3 bits. This leaves 5 bits for the subnets 11111000 converted to decimal: 128+64+32+16+8=248, therefore the subnet mask will be: 255.255.255.248. Reference: Deborah Littlejohn Shinder, Dr. Thomas W. Shinder, Chad Todd and Laura Hunter, MCSA/MCSE: Exam 70-291: Implementing, Managing, and Maintaining a Windows Server 2003 Network Infrastructure Guide & DVD Training System, p.57 QUESTION: 5 You work as the network administrator at Certmagic.com. The Certmagic.com network consists of a single Active Directory domain named Certmagic.com. Certmagic.com has its headquarters in Chicago and a branch office in Dallas. All servers on the Certmagic.com network run Windows Server 2003 and all client computers run Windows XP Professional. You work in the Dallas branch office. The network at the Dallas branch office consists of a single subnet that contains 150 client computers and 12 servers. The network administrator at headquarters has allocated the 10.10.0.0/16 6 http://www.certmagic.com
Slide 7: 070-291 network address to the Dallas branch office. You have received instruction from your manager to place all servers at the Dallas branch office into a separate subnet that uses the 192.168.10 public addressing scheme. Your manager asks you to make allowance for a maximum of 30 servers in the new subnet. Which subnet mask should you use for the new subnet? A. 255.255.255.224 B. 255.255.255.240 C. 255.255.255.248 D. 255.255.255.252 E. 255.255.255.254 Answer: A Explanation: A 255.255.255.224 subnet mask gives five host address bits, so the maximum number of host addresses is 2 ^ 5 - 2 = 30 host addresses. Thus 255.255.255.224 is the only subnet mask that will allow for sufficient IP addresses in case of further growth, whilst still conserving as many current addresses as possible.

Shinder, Chad Todd and Laura Hunter, MCSA/MCSE: Exam 70-291: Implementing, Managing, and Maintaining a Windows Server 2003 Network Infrastructure Guide & DVD Training System, p. 62 QUESTION: 6 DRAG DROP You work as the network administrator at Certmagic.com. The Certmagic.com network consists of a single Active Directory domain named Certmagic.com. All servers on the Certmagic.com network run Windows Server 2003 and all client computers run Windows XP Professional. You have installed a new server named Certmagic-SR06 on the network. The relevant portion of the network is shown on the exhibit. 7 http://www.certmagic.com
Slide 8: 070-291 You want to configure Certmagic-SR06 with a valid static IP configuration. CertmagicSR06 must be able to communicate with all hosts on the network and on the internet. You also need to configure Certmagic-SR06 to use the DNS server on the local subnet for name resolution. In addition, you must configure redundancy for name resolution. How should you configure Certmagic-SR06? To answer drag the appropriate IP addresses and Subnet masks to the appropriate places. 8 http://www.certmagic.com
Slide 9: 070-291 Answer: 9 http://www.certmagic.com
Slide 10: 070-291 Explanation: The Class C address 192.168.0.100 has to be the IP address to enable Certmagic-SR06 to communicate with all hosts on the network and on the internet as 192.168.0.1, 192.168.0.2 and 192.168.0.110 are already in use. 192.168.5.2 and 192.168.5.100 are on the wrong subnet, and besides, 192.168.5.12 is already in use. The subnet mask for this Class C address is 255.255.255.0. The default gateway should be 192.168.0.1. To configure redundancy for name resolution, configure the preferred DNS server/primary address as 192.168.0.2, and the alternate DNS server/secondary address as 192.168.5.2. Reference: J. C. Mackin, Ian McLean, MCSA/MCSE Self-Paced Training Kit (exam 70-291): Implementing, Managing, and Maintaining a Microsoft Windows Server 2003 network Infrastructure, Part 1, Chapter 2, pp. 80-116 QUESTION: 7 You work as the network administrator at Certmagic.com. The Certmagic.com network consists of a single Active Directory domain named Certmagic.com. All servers on the Certmagic.com network run Windows Server 2003 and all client computers run 10 http://www.certmagic.com
Slide 11: 070-291 Windows XP Professional. Certmagic.com has its headquarters in Chicago and branch offices in Dallas and Miami. You work in the Miami branch office. The Miami branch office has a file server named Certmagic-SR25 that hosts critical documents. Certmagic-SR25 is configured with a DHCP client reservation. Certmagic.com users from all three offices download documents from Certmagic-SR25. One day Certmagic.com users complain that they cannot access the documents on CertmagicSR25. You discover that the DHCP server has failed. The DHCP server is located at headquarters. You have received instruction from the CIO to ensure that CertmagicSR25 is available even if it is unable to obtain or renew a lease from the DHCP server. How could you accomplish this task? A. On the DHCP server, increase the DHCP lease period. B. Configure alternate IP settings for Certmagic-SR25 on the Alternate Configuration tab of the Internet Protocol (TCP/IP) properties. C. Configure the DHCP scope in the 169.254.0.1. - 169.254.255.254 range. D. On the DHCP server, configure the DHCP 001 Resource Location Servers reservation option for Certmagic-SR25. Answer: B Explanation: Windows Server 2003 includes the Alternate Configuration feature. The Windows Server 2003 servers can be configured to use an alternate static IP configuration if a DHCP server is unavailable. When a DHCP client determines that the DHCP server is unavailable, it will automatically change over and also configure the TCP/IP stack with the static address information specified on the Alternate Configuration tab of the Internet Protocol (TCP/IP) properties. Incorrect Answers: A: Increasing the lease period would result in DHCP clients requesting leases less frequently, but won't guarantee that Certmagic-SR25 will be available when the DHCP server is down. C: Modifying the DHCP scope to the 169.254.0.1. - 169.254.255.254 range will still be reliant on the DHCP server. D: Configuring the DHCP 001 Resource Location Servers reservation option for Certmagic-SR25 on the DHCP server will not ensure that Certmagic-SR25 will receive an IP address or have the IP address renewed.

Slide 12: 070-291 QUESTION: 8 You work as the network administrator at Certmagic.com. The Certmagic.com network consists of a single Active Directory domain named Certmagic.com. All servers on the Certmagic.com network run Windows Server 2003 and all client computers run Windows XP Professional. The Certmagic.com network contains a server named Certmagic-SR34. Certmagic-SR34 is configured as a DHCP server and has been authorized in Active Directory. The Telnet service has been installed and started on Certmagic-SR34. One day Certmagic.com users complain that they cannot access network resources. Your investigations reveal that the DHCP Server service on Certmagic-SR34 has stopped. You install the administrative tools on a client computer named Certmagic-WS291 and log on to the computer. When you open the DHCP console on Certmagic-WS291 and attempt to connect to Certmagic-SR34, you receive an error message that states: "Cannot find the DHCP Server." You then attempt to ping Certmagic-SR34 but fail. How can you connect to the DHCP Server service on Certmagic-SR34 by using the DHCP console on Certmagic-WS291? A. Establish a Telnet session to Certmagic-SR34 and then run the net start dhcp command. B. Establish a Telnet session to Certmagic-SR34 and then run the net start dhcpserver command. C. Establish a Telnet session to Certmagic-SR34 and then run the ipconfig /renew command. D. On Certmagic-WS291, run the netsh dhcp server\\ Certmagic-SR34 show server command. Answer: B Explanation: You can start the DHCP Server service by executing the Net Start Dhcpserver command at the command prompt. Telnet is a protocol that enables an Internet user to log on to and enter commands on a remote computer linked to the Internet, as if the user were using a text-based terminal directly attached to that computer. Telnet is part of the TCP/IP suite of protocols. The term telnet also refers to the software (client or server component) that implements this protocol. Given the fact that you can ping CertmagicSR34 you should then establish a Telnet session to Certmagic-SR34 and then run the appropriate command. Reference: J. C.

Slide 13: 070-291 You work as the network administrator at Certmagic.com. The Certmagic.com network consists of a single Active Directory domain named Certmagic.com. All servers on the Certmagic.com network run Windows Server 2003 and all client computers run Windows XP Professional. The Certmagic.com network contains a server named Certmagic-SR51 that is configured as a print server for a print device that has a built-in network interface. The print device is used by the Sales department to print Sales reports. A Certmagic.com user named Clive Allen is a member of the Sales department. Clive Allen complains that he cannot print to the print device attached to CertmagicSR51. You verify that the IP address for Certmagic-SR51 is correct and that the correct drivers for the print device are installed. You now want to verify that the print jobs are being sent to the correct MAC address for Certmagic-SR51. You log on to CertmagicSR51. What should you do next? A. Run the net session command. B. Run the netstat command. C. Run the netsh command. D. Run the netcap command. Answer: D Explanation: Netstcap.exe is a command line tool that could be used to capture the network traffic.

Slide 15: 070-291 You work as the network administrator at Certmagic.com. The Certmagic.com network consists of a single Active Directory domain named Certmagic.com. All servers on the Certmagic.com network run Windows Server 2003 and all client computers run Windows XP Professional. The Certmagic.com network contains a Microsoft Internet Security and Acceleration (ISA) Server computer named Certmagic-SR01, a DNS server named Certmagic-SR02, a DHCP server named Certmagic-SR03, a file server named Certmagic-SR21, and a Web server named CERTMAGIC-SR25. CertmagicSR25 also serves as a central antivirus server. Certmagic-SR21 is located on the 10.10.11.0 subnet and Certmagic-SR25 is located in the perimeter network. CertmagicSR21 contains antivirus software that checks for new virus definitions on CertmagicSR25 every hour. You can also access Certmagic-SR25 through a virus update Web page to perform manual virus definition updates. Certmagic-SR03 suffers a catastrophic failure and is removed from the network. Due to budgetary constraints, a replacement for Certmagic-SR03 will only be acquired in the next financial year. You need to redesign network addressing scheme, and change the IP addresses for Certmagic-SR01 15 http://www.certmagic.com
Slide 16: 070-291 to the addresses shown in the Network Topology exhibit. Certmagic-SR02 contains the new host (A) resource records for Certmagic-SR01. You receive reports about a new virus threat and want to protect the network immediately by manually downloading the new virus definitions to Certmagic-SR21. you log on to Certmagic-SR21 but discover that you cannot access the virus update Web page on Certmagic-SR25. The static TCP/IP configuration on Certmagic-SR21 uses Certmagic-SR02 as the preferred DNS server. You confirm that Certmagic-SR01 is configured properly. On Certmagic-SR21, you view the Internet Explorer LAN settings that are shown in the LAN Settings exhibit. What should you do to allow Certmagic-SR21 to connect to Certmagic-SR25? A. At a command prompt on Certmagic-SR21, run the ipconfig /flushdns command. B. In the LAN settings of Internet Explorer on Certmagic-SR21, select the Automatically detect settings check box. C. At a command prompt on Certmagic-SR01, run the ipconfig / flushdns command. D. At a command prompt on Certmagic-SR01, run the ipconfig /registerdns command. Answer: A Explanation: Running the ipconfig /flushdns command will flush and reset the DNS resolver cache which is necessary to allow connection. Run this command on Certmagic-SR21 to connect to Certmagic-SR25. Incorrect Answers: B: Selecting the "Automatically detect settings" checkbox is not going to allow Certmagic-SR21 to connect to WWW. C: The ipconfig /flushdns command flushes and resets the DNS resolver cache. This is not what is necessary. D: The ipconfig /registerdns command refreshes all DHCP leases and registers any related DNS names. This option is available only on Windows 2000 and newer computers that run the DHCP Client service. This is not going to allow CertmagicSR21 to connect to WWW when it is run on Certmagic-SR01.

All servers on the Certmagic.com network run Windows Server 2003 and all client computers run Windows XP Professional. The Certmagic.com network contains a DHCP server 16 http://www.certmagic.com
Slide 17: 070-291 named Certmagic-SR15 that is configured with a single scope. Certmagic.com hires a new Sales manager named Andy Reid. You install a new client computer named Certmagic-WS291 for Andy Reid. You connect Certmagic-WS291 to the network by plugging the network cable into the network adapter on Certmagic-WS291 and attempt to connect to Certmagic-SR25. However, you cannot access any of the servers on the network. When you open a command prompt on Certmagic-WS291 and run the ipconfig /renew command, you receive the following response. You log on to a client computer named Certmagic-WS292 and run the ipconfig /renew command successfully. What should you do to ensure that Certmagic-WS291 can receive its IP address configuration from the Certmagic-SR25? A. Restart the DHCP service on Certmagic-SR25. B. Restart Certmagic-WS291. C. Restart Certmagic-SR25. D. Add additional IP addresses to the scope on Certmagic-SR25. Answer: B Explanation: It is probable that the TCP/IP stack has a problem because the computer is unable to send a DHCP discover broadcast packet. This can happen when you insert a network cable after the PC has been started. You should restart the client PC to successfully obtain a new IP address. Incorrect Answers: A, C, D: This is unnecessary because Certmagic-WS292 did obtain an IP address from the DHCP server, thus indicating that the DHCP server configuration is not the issue.

Slide 18: 070-291 Training System, p. 629 QUESTION: 12 You work as the network administrator at Certmagic.com. The Certmagic.com network consists of a single Active Directory domain named Certmagic.com. All servers on the Certmagic.com network run Windows Server 2003 and all client computers run Windows XP Professional. Certmagic.com has its headquarters in Chicago and branch offices in Dallas and Miami. The Certmagic.com network contains a DHCP server named Certmagic-SR01. The relevant portion of the network is shown in the following network diagram. You work at headquarters. A Certmagic.com employee named Andy Booth is one of three employees that are relocated to headquarters from the Dallas office. Andy Booth uses a portable client computer named Certmagic-WS291. Andy Booth complains that when he plugs Certmagic-WS291 into the LAN connection in his new cubicle, he cannot connect to network resources on the LAN or the Internet. None of the other employees are experiencing the same problem. When you run the ipconfig command from a command prompt on Certmagic-WS291, you see the output as shown in the exhibit. What should you do to allow Certmagic-WS291 to connect to network resources on the LAN or the Internet? 18 http://www.certmagic.com
Slide 19: 070-291 A. Configure Certmagic-WS291 with a subnet mask of 255.255.240.0. B. Configure Certmagic-WS291 with a default gateway of 192.168.3.12. C. Configure Certmagic-WS291 with a primary DNS suffix of Certmagic.com. D. Configure Certmagic-WS291 to automatically lease an IP address from CertmagicSR01. Answer: D Explanation: The client computers on the subnet use DHCP to obtain their IP configurations. Certmagic-WS291 has a static IP address, and therefore cannot obtain a valid IP configuration from the DHCP server. Incorrect Answers: A: By changing the subnet mask you will not ensure that Certmagic-WS291 will connect to other computers and the Internet. B: Changing the default gateway will not enable Certmagic-WS291 LAN connection. Besides, 192.168.3.12 is the IP address of the DHCP server. C: Adding a primary DNS suffix means that only domain names listed in that window will be tried for resolution purposes. Both the connection-specific and primary DNS suffix are ignored.

The Certmagic.com network consists of a single Active Directory domain named Certmagic.com. All servers on the Certmagic.com network run Windows Server 2003 and all client computers run Windows 2000 Professional. Certmagic.com has headquarters in London and branch offices in Paris, Berlin, Milan, Madrid, Stockholm, Warsaw, Minsk, and Athens. Each branch office has a server that provides DHCP Server services and between two to twenty client computers. A client computer in each branch office is configured with a shared dial-up connection. You work at headquarters. The Berlin branch office has only two client computers named Certmagic-WS291 and Certmagic-WS292. A Certmagic.com user named Kara Lang works in the Berlin office. One morning Kara Lang complains that the shared dial-up connection on Certmagic-WS291 is no longer working. Your investigation reveals that Certmagic-WS292 can connect to shared folders on Certmagic-WS291 and that Certmagic-WS291 can connect to the network at headquarters. However, Certmagic-WS292 cannot connect to resources on the network 19 http://www.certmagic.com
Slide 20: 070-291 at headquarters. What should you do to ensure that both Certmagic-WS291 and Certmagic-WS292 can connect to resources on the network at headquarters? A. Reconfigure Internet Connection Sharing on Certmagic-WS291. B. Configure the shared dial-up connection on Certmagic-WS291 so that automatic dialog is enabled. C. Configure Certmagic-WS292 to receive an IP lease from a DHCP server. D. Configure Certmagic-WS292 to use Certmagic-WS291 for DNS name resolution. Answer: C. Explanation: The problem is most likely caused by an incorrect or non-existent default gateway setting on Certmagic-WS292. If you configure Certmagic-WS292 to use DHCP to obtain IP addressing information, Certmagic-WS292 will receive the correct settings from the ICS service on Certmagic-WS291. Incorrect Answers: A: The question refers to a shared dial-up connection on Certmagic-WS291 not working. If the dial-up connection is shared, then Internet Connection Sharing is enabled already. B: The question states that Certmagic-WS291 automatically connects to the network at the main office whenever the user on Certmagic-WS291 attempts to access resources located on the main office network. This indicates that automatic dial-up is already configured. D: Certmagic-WS291 is not a DNS server. The ICS service has a DNS proxy that would pass DNS requests to whichever DNS server Certmagic-WS291 is using. Reference: J. C.

The Certmagic.com network consists of a single Active Directory domain named Certmagic.com. All servers on the Certmagic.com network run Windows Server 2003 and all client computers run Windows NT Workstation 4.0. The network contains 2,500 client computers that are configured with static IP addresses. Certmagic.com issues a new network policy that requires all network computers to have dynamically assigned IP configurations. You enable the DHCP Server service on a member server named Certmagic-SR25. Three network support technicians have been instructed to configure the IP properties on all client computers to receive a DHCP lease from Certmagic-SR25. It is estimated that the 20 http://www.certmagic.com
Slide 21: 070-291 change over will take two weeks to complete. You need to ensure that the DHCP server will not lease an IP address that is statically configured on a computer that the network support technicians have not yet seen to. What should you do? A. On Certmagic-SR25, configure Conflict detection attempts to 1. B. On Certmagic-SR25, configure Conflict detection attempts to 3. C. On Certmagic-SR25, configure client reservations for each client computer's MAC address. D. On Certmagic-SR25, activate and reconcile the scopes. Answer: A Explanation: When conflict detection attempts are set, the DHCP server uses the Packet Internet Groper (ping) process to test available scope IP addresses before including these addresses in DHCP lease offers to clients. A successful ping means that the IP address is in use on the network. This results in the DHCP server not offering to lease the address to a client. If the ping request fails and times out, it indicates that the IP address is not in use on the network. In this case, the DHCP server offers to lease the address to a client. Each additional conflict detection attempt delays the DHCP server response by a second while waiting for the ping request to time out. This in turn increases the load on the server. A value of no greater than two (2) is recommended for ping attempts. Incorrect Answers: B: Due to the latency involved in ping attempts, the higher the conflict detection value is set, the longer the lease process will be for every client that uses the DHCP server. C: Configuring client reservations for each client computer MAC address will involve a physical visit to each and every client computer if you do not ping it successfully. D: The scope would already be activated in this scenario. Reference: Deborah Littlejohn Shinder, Dr. Thomas W. Shinder, Chad Todd and Laura Hunter, Implementing, Managing, and Maintaining a Windows Server 2003 Network Infrastructure Guide & DVD Training System, pp. 208-209 QUESTION: 15 You work as the network administrator at Certmagic.com. The Certmagic.com network consists of a single Active Directory domain named Certmagic.com. All servers on the Certmagic.com network run Windows Server 2003 and client computers run Windows XP Professional, Windows 2000 Professional, or Windows NT Workstation. All client computers are configured with default settings. The Certmagic.com network contains a server named Certmagic-SR31 that functions as a DHCP and DNS server, and a server named Certmagic-SR38 that contains antivirus server software. All DNS zones on 21 http://www.certmagic.com
Slide 22: 070-291 Certmagic-SR31 are enabled for DNS dynamic updates. The computer account for each client computer is the owner of its own DNS host record. No other server provides DNS services. What must you do to ensure that Certmagic-SR38 can contact client computers by using fully qualified domain names (FQDNs) to propagate virus definition updates? A. On Certmagic-SR31, modify the Dynamically update DNS A and PTR records only if requested by the DHCP clients option. B. On Certmagic-SR38, modify the Always dynamically update DNS A and PTR records option. C. On Certmagic-SR31, modify the Discard A and PTR records when lease is deleted option. D. On Certmagic-SR31, modify the Dynamically update DNS A and PTR records for DHCP clients that do not request dynamic updates (for example, clients running Windows NT 4.0) option. Answer: D Explanation: Dynamically Update DNS A And PTR Records For DHCP Clients That Do Not Request Updates - This checkbox lets you handle these older clients graciously by making the updates using a separate mechanism. When checking this check box you will ensure that Certmagic-SR38can resolve FQDNs for all client computers on the network under the given circumstances and the role that Certmagic-SR31 plays. Incorrect Answers: A: Dynamically Update DNS A And PTR Records Only If Requested By The DHCP Clients - This radio button (which is on by default) tells the DHCP server to register the update only if the DHCP client asks for DNS registration. When this button is active, DHCP clients that aren't hip to DDNS won't have their DNS records updated. However, Windows 2000, XP, and Server 2003 DHCP clients are smart enough to ask for the updates. B: Always Dynamically Update DNS A And PTR Records - This radio button forces the DHCP server to register any client to which it issues a lease. This setting may add DNS registrations for DHCP-enabled devices that don't really need them, like printer servers; however, it allows other clients (like Mac OS, Windows NT, and Linux machines) to have their DNS information automatically updated. This is not what is required. C: Discard A And PTR Records When Lease Is Deleted - When a DHCP lease expires, what should happen to the DNS registration? Obviously, it would be nice if the DNS record associated with a lease vanished when the lease expired; when this checkbox is checked (as it is by default), that's exactly what happens. If you uncheck this box, your DNS will contain entries for expired leases that are no longer valid; when a particular IP address is reissued on a new lease, the DNS will be updated, but in between leases you'll have incorrect data in your DNS-always something to avoid. 22 http://www.certmagic.com

The Certmagic.com network consists of a single Active Directory domain named Certmagic.com. All servers on the Certmagic.com network run Windows Server 2003 and all client computers run Windows XP Professional. The Certmagic.com network contains a stand alone server named Certmagic-SA09 that is not a member of the domain, and a DNS server named Certmagic-SR22. Certmagic-SA09 has the static IP address 192.168.3.27 and Certmagic-SR22 has the IP address 192.168.3.1. The Certmagic.com zone is configured to accept only secure DNS updates. You install a new client-server application on Certmagic-SA09. The client software is installed on client computers named Certmagic-WS291 and Certmagic-WS292. Certmagic-WS291 and CertmagicWS292 are members of domain. You need to install the client software on the other client computers in the domain. The client software will connect to Certmagic-SA09 by using the fully qualified domain name (FQDN) Certmagic-SA09. Certmagic.com. You successfully ping 192.168.6.23 from Certmagic-WS291. However, when you attempt to run the client software on Certmagic-WS291 and Certmagic-WS292, the software fails to locate Certmagic-SA09 and stops. Using the minimum amount of administrative effort, what should you do to ensure that the client software can locate CertmagicSA09? A. From a command prompt on Certmagic-SA09, run the ipconfig /registerdns command. B. On both Certmagic-WS291 and Certmagic-WS292, add the line Certmagic-SA09. Certmagic.com 192.168.6.23 #pre to the Hosts file. C. On a domain controller, create an OU named AppServerOU and add the computer account for Certmagic-SA09 to the AppServerOU. Then, set the Primary DNS Suffix Group Policy setting on an AppServerOU GPO to Certmagic.com and restart Certmagic-SA09. D. On Certmagic-SR22, enter a host (A) record for Certmagic-SA09 that maps the IP address 192.168.6.23 to Certmagic-SA09. Then, configure Certmagic-SA09 with Certmagic.com as the primary DNS suffix and restart Certmagic-SA09. E. Configure Certmagic-SA09 with a Preferred DNS server IP address of 192.168.6.1. Answer: D Explanation: Every computer in a Windows Server 2003 network can be assigned a primary DNS 23 http://www.certmagic.com
Slide 24: 070-291 suffix to be used in name resolution and name registration. The primary DNS suffix is specified on the Computer Name tab of the properties dialog box in My Computer. The primary DNS suffix is also known as the primary domain name and the domain name. The full computer name is a type of FQDN. The same computer can be identified by more than one FQDN, but only the FQDN that concatenates the host name and the primary DNS suffix represents the full computer name. If you can ping a computer by IP address but not by name, the computer is missing an A resource record in DNS. You can attempt to remedy this situation by executing the Ipconfig /registerdns command at that computer. Therefore, if you want to run client software successfully on the two computers under the circumstances as given in the question, option D would be the answer. Incorrect Answers: A: If you can ping a computer by IP address but not by name, the computer is missing an A resource record in DNS. You can attempt to remedy this situation by executing the Ipconfig /registerdns command at that computer. However, this is only part of the solution. B: This option will not allow you to run client software on the two computers. C: This option suggests too much administrative effort to be done. E: This will not enable you to run client software on the two computers in the given circumstances. Reference: James Chellis, Paul Robichaux and Matthew Sheltz, MCSA/MCSE: Windows Server 2003 Network Infrastructure Implementation, Management, and Maintenance Study Guide, p. 4-5, 4-34 QUESTION: 17 You work as the network administrator at Certmagic.com. The Certmagic.com network consists of a single Active Directory domain named Certmagic.com. Certmagic.com has its headquarters in Chicago and a branch office in Dallas. The Chicago and Dallas offices are connected by a router. All servers on the Certmagic.com network run Windows Server 2003 and are configured with static IP addresses. All client computers on the Certmagic.com network run Windows XP Professional and are configured as DHCP clients. Half the client computers are portable computers, and the rest are desktop computers. A DHCP server is located in each office. The DHCP server at the Dallas office shuts down unexpectedly and is brought back online four hours later. In the interim, several Certmagic.com users with portable client computers connect their client computers to the network. These users complain that they cannot access any of the network resources on the domain. You create a new scope on the two DHCP servers that includes IP addresses for the other office and activate the scopes. However, when you test the new DHCP configuration by disconnecting the DHCP server at headquarters, the client computers at that office do not receive IP addresses from the DHCP server in the Dallas branch office. How can you ensure that client computers will receive a correct IP address configuration from the DHCP server in the other office 24 http://www.certmagic.com
Slide 25: 070-291 when the DHCP server in one office fails? (Each correct answer presents a complete solution. Choose two) A. Configure the router that connects the two offices to forward BOOTP broadcasts. B. Configure the DHCP server in each office with a DHCP scope that includes the same IP addresses as the DHCP server in the other office and activate the scope. C. Install another network adapter in the DHCP server in each office. Connect each new network adapter to the local network and assign an IP address from the other office's network to each new network adapter. D. Install a DHCP relay agent in each office. Answer: A, D Explanation: In a subnetted environment, routers and remote computers can be configured to be DHCP Relay Agents, which forward DHCP information between subnets. The router forwards requests for IP address configuration assignments to the remote DHCP Server. The DHCP Relay Agent is typically configured on a network segment where there is no DHCP server. The network segments are normally on the other end of a non 2131 compliant router from a DHCP server. The DHCP Relay Agent assists in passing on DHCP and BOOTP broadcast messages over routers which do not support the passing on of these messages. The DHCP server configured in the DHCP Relay Agent's properties through the DHCP Relay Agent performs the DHCP lease process. The server specified apply to each network interface that the relay agent is attached to. Instead of using the approach just outlined, you can configure the router between the offices to forward BOOTP broadcasts. Incorrect Answers: B: Configuring a scope and activating it to include the same IP addresses as the DHCP server in the other office will not work. This will be akin to having two places with the same address. C: The question states that you need to make sure that in case of failure the client computers will receive a correct IP address configuration from the DHCP server in the other office. You thus do not have to add in additional network adapters and DHCP servers. Reference: Deborah Littlejohn Shinder, Dr. Thomas W.

Slide 26: 070-291 QUESTION: 18 You work as the network administrator at Certmagic.com. The Certmagic.com network consists of a single Active Directory domain named Certmagic.com. All servers on the Certmagic.com network run Windows Server 2003 and all client computers run Windows XP Professional. The Certmagic.com network contains a DHCP server named Certmagic-SR31, and a DNS server named Certmagic-SR32. All servers on the Certmagic.com network have static IP addresses. The relevant portion of the network is shown in the Network exhibit. You configure Certmagic-SR31 to lease IP addresses to all of the client computers on the 10.9.7.0 subnet. The DHCP server scope settings on Certmagic-SR31 are shown in the DHCP exhibit. 26 http://www.certmagic.com
Slide 27: 070-291 However, all Certmagic.com users on the 10.9.7.0 subnet complain that they cannot access any network resources or the Internet. They can only access other client computers on the local subnet. Certmagic.com users on the 10.9.8.0 subnet can access servers on both subnets and can access the Internet. What should you do to ensure that all client computers can access the Internet? A. Configure the DHCP Relay Agent on Certmagic-SR32. B. On Certmagic-SR32, add a host (A) record for Certmagic-SR31 at address 10.9.8.91. C. Activate the 10.9.7.0 scope on Certmagic-SR31. D. Disable the 001 Microsoft Disable Netbios Option Certmagic-SR3 Certmagic-SR31. Answer: A Explanation: DHCP Relay Agent is a routing protocol that allows client computers to obtain an address from a DHCP server on a remote subnet. Typically, DHCP clients broadcast DHCP Discover packets that are then received and answered by a DHCP server on the same subnet. Because routers block broadcasts, DHCP clients and servers must normally be located on the same physical subnet. DHCP relay agents intercept DHCP Discover packets and forward them to a remote DHCP server whose address has been preconfigured. Since Certmagic-SR31 contains the DHCP server and the Internet is accessed through the router, you should configure the DHCP Relay Agent on Certmagic-SR32 so as to ensure that all the client computers can access the Internet. Incorrect Answers: B: Adding a host (A) record for Certmagic-SR31 at address 10.9.8.91 on CertmagicSR32 will not ensure accessibility to the Internet for all the client computers. C: There is no need to activate the 10.0.7.0 scope on Certmagic-SR31. This will not solve the problem. D: Disabling the 001 Microsoft Disable Netbios Option on Certmagic-SR31 will not solve the problem of accessibility to the Internet for all client computers. 27 http://www.certmagic.com

All client computers must be able to connect to each other you must minimize additional network services. What should you do? A. Configure Routing and Remote Access on Certmagic-SR02 and configure a DHCP relay agent on Certmagic-SR03. B. Configure Routing and Remote Access on Certmagic-SR03 and configure a DHCP relay agent on Certmagic-SR02. C. Configure Routing and Remote Access and a DHCP relay agent on Certmagic-DC01. D. Configure Routing and Remote Access and a DHCP relay agent on Certmagic-SR02. E. Configure Routing and Remote Access and a DHCP relay agent on Certmagic-SR03. Answer: C Explanation: Certmagic-DC01 is connected to both network segments and can therefore act as a router. To enable this, configure Routing and Remote Access on Certmagic-DC01. To enable the clients on the 192.168.1.0 subnet to obtain their TCP/IP configurations from the DHCP server, you need to configure a DHCP relay agent on the 192.168.1.0 subnet. The DHCP relay agent service is part of Routing and Remote Access; therefore, you need to configure a DHCP relay agent on Certmagic-DC01. Incorrect Answers: A: Certmagic-SR02 will not be a router and therefore does not need the Routing and Remote Access service and the relay agent needs to be configured on the 192.168.1.0 subnet. B: Certmagic-SR03 will not be a router and therefore does not need the Routing and Remote Access service. D: Certmagic-SR02 will not be a router and therefore does not need the Routing and Remote Access service.
