Slide 1: RH302 - Red Hat Linux Certification (RHCE) FREE RH302 Practice Exam Test Questions Made Available By Pass-Guaranteed.com RH302 Practice Exam Questions For The Latest RH302 Practice Exam Questions: Visit: RH302
Slide 2: Introduction Under Red Hat Enterprise Linux 4, the certification exam consists of two parts conducted in a single day. The exam is performance-based, meaning that candidates must perform tasks on a live system, rather than answering questions about how one might perform those tasks. The two parts of the RHCE Exam consist of: • Section I: Troubleshooting and System Maintenance (2.5 hours) • Section II: Installation and Configuration (3 hours) In order to pass the Red Hat Certified Engineer exam under Red Hat Enterprise Linux 4, you must meet all of the following requirements: • a score of 80 or higher on Section I, consisting of five compulsory and five optional problems; • successful completion of the five Section I compulsory troubleshooting problems within one hour of that section's start time; • 70 percent or more on the RHCT-level skills in Section II; • 70 percent or more on the RHCE-level skills in Section II. These last two requirements enable RHCEs to demonstrate that they possess both RHCT level and RHCE-level skills, as well as enabling a person who only has RHCT level skills to earn RHCT if they pass the required competencies. Lab Setup on RHCE Exam: Remember the Key points of Lab Configuration: 1. Lab Configuration is on 192.168.0.0/24 for example.com domain and 192.168.1.0/24 for cracker.org domain. 2. DHCP Server is configured. 3. DNS Server is 192.168.0.254 4. One NIS Server is configured RHCE and server is 192.168.0.254 In Debug Section Five Questions are compulsory! You should finish these questions within an hour. Topic 1, Debug Section QUESTION: 1 How can you make this successfully resolve to server1.example.com where DNS Server is 192.168.0.254. Answer: 1. vi /etc/resolv.conf Write: nameserver 192.168.0.254 Explanation: If you have multiple name server (DNS), you can append another line. First Request goes to the First name server if not found then goes to second name server. For The Latest RH302 Practice Exam Questions: Visit: RH302
Slide 3: Then try to resolve the Server1.example.com by using host or dig command. Eg: host server1.example.com When we use the DNS client tool first it sends the request to the DNS server specified in /etc/resolv.conf as a name server. If that DNS is not found then it sends the request to the Root name Server. I will explain about the root Name server. QUESTION: 2 Quota is implemented in /data but not working properly. Find out the Problem and implement the quota to user1 to have a soft limit 60 i-nodes (files) and hard limit of 70 i-nodes (files). Answer: You should implement the quota on any directory that should be mounted with usrquota option for user quota and grpquota for group quota. 1. vi /etc/fstab /dev/hda11 /data ext3 defaults,usrquota 0 0 2. Either Reboot the System or remount the partition. Mount -o remount /dev/hda11 /data 3. touch /data/aquota.user 4. quotacheck -ufm /data 5. quotaon -u /data 6. edquota -u user1 /data and Specified the Soft limit and hard limit on opened file. To verify either quota is working or not: i. Login as user1 ii. Create the 61 files and see the warning of soft limit. iii use the quota command. QUESTION: 3 One Logical Volume named lv1 is created under vg0. The Initial Size of that Logical Volume is 100MB. Now you required the size 500MB. Successfully make the size of that Logical Volume 500M without losing any data. As well as size should be increased online. Answer: In RHEL 4 LVM (Logical Volume Manager) is Version 2. The new feature added is online extend. In previous version you should unmount the device. 1. Verify the size of Logical Volume: lvdisplay /dev/vg0/lv1 2. Verify the Size on mounted directory: df -h or df -h mounted directory name 3. Use : lvextend -L+400M /dev/vg0/lv1 4. ext2online -d /dev/vg0/lv1 to bring extended size online. 5. Again Verify using lvdisplay and df -h command. Explanation: The Feature of LVM is dynamically resize the partition. If you resize data, it will not be lost. LVM Concepts Multiple Physical Disks belongs to the physical group. Using multiple disks belonging to physical group we can create on the Volume group. Under that Volume For The Latest RH302 Practice Exam Questions: Visit: RH302
Slide 4: Group we can create multiple Logical Volume and only these Logical Volumes we can use. As well as we can increase and decrease the size of Logical Volume by using lvextend, lvresize etc. QUESTION: 4 Create one partition having the size of 100MB and mount it on /data. Answer and Explanation: 1. Use fdisk /dev/hda To create new partition. 2. Type n For New partitions 3. It will ask for Logical or Primary Partitions. Press l for logical. 4.

Answer and Explanation: For The Latest RH302 Practice Exam Questions: Visit: RH302
Slide 5: 1. /proc is the virtual filesystem, we use /proc to modify the kernel value at running time. So For Current Session: echo "1" >/proc/sys/net/ipv4/ip_forward 2. /etc/sysctl.conf when System Reboot on next time, /etc/rc.d/rc.sysinit scripts reads the file /etc/sysctl.conf. So if you want to permanently set the IP forwarding enable, You should set: net.ipv4.ip_forward=1 Here 0 means disable, 1 means enable.

Permissions are defined to owner user, owner group and other. -rwxr-x--- Full permission to owner user, read and write to owner group and no permission to others. According to question: We should give the full permission to user user1 without changing the previous permission. We have ACL (Access Control List), in ext3 file system we can give certain permissions to a certain user and a certain group without changing previous permissions. But that partition should mount using acl option. Follow the steps: 1. vi /etc/fstab /dev/hda14 /data ext3 defaults,acl 0 1 2. Either Reboot or use: mount -o remount /data 3. setfacl -m u:user1:rwx /data 4. Verify using: getfacl /data QUESTION: 15 You are giving the RHCE exam. Now you should boot your System properly.

Examiner gave you the Boot related problem and told to you that make successfully boot the System. When you started the system you got some error message: Kernel Panic - not syncing: Attempted to kill init! And no further boot process. What you will do to boot the system. Answer and Explanation: If you are getting the Kernel panic error, it means it is boot loader related problem. Red Hat Enterprise Linux uses the GRUB boot loader. You can pass the kernel parameter from the boot loader as well as you can correct the kernel parameter passing from boot loader from GRUB screen at boot time. GRUB boot loader configuration file is: /etc/grub.conf And Correct Configuration is: default=0 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title Red Hat Enterprise Linux ES (2.6.9-5.EL) root (hd0,0) kernel /vmlinuz-2.6.9-5.EL ro root=LABEL=/ rhgb quiet initrd /initrd-2.6.9-5.EL.img Probably miss-configured the boot loader so, giving this problem. You can pass the correct parameter from GRUB prompt by pressing e To edit the configuration, a to append the parameter, and c for command-line. If you know the boot partition you can enter following line: Press c on GRUB screen. Grub> root (hd0,0) grub> kernel /vmlinuz-2.6.9-5.EL ro root=LABEL=/ rhgb quiet grub> initrd /initrd-2.6.9-5.EL.img grub>boot QUESTION: 18 You are given the RHCE exam. The examiner gave you the Boot related problem and told you to successfully boot the System. When you started the system, System was automatically asking you for the root password. How will you fix that problem? Answer and Explanation: Boot loader points to Boot partition and root partition. Mount the root partition on read only mode. Automatically asking for root password at system boot time means, file system error. It comes generally from /etc/fstab Ie. Unknow partition, bad filesystem, bad mounting options, bad LABEL etc. Follow the steps 1. Give the Root password 2. fdisk -l Verify the Number of parations. 3. Identify the Root partition, e2label /dev/hda1, e2label /dev/hda2..... 4.

There is a common data shared (/data) from 192.168.0.254 to all users in your local LAN. When a user's system starts, shared data should automatically mount on the user's machine. How will you configure this? Answer And Explanation: To automatically mount at boot time, we use the /etc/fstab file. Because /etc/rc.d/rc.sysinit file reads and mount all file system specified in /etc/fstab. To mount Network Sharing Files also use the /etc/fstab but filesystem is nfs. 1. vi /etc/fstab 192.168.0.254:/data /common nfs defaults 0 0 2. reboot the system. QUESTION: 20 One Logical Volume is created named as myvol under VO volume group and is mounted. The Initial Size of that Logical Volume is 124MB. Successfully make the size of Logical Volume 245MB without losing any data. The size of the Logical Volume from 240MB to 255MB will be acceptable. Answer and Explanation: 1. First check the size of the Logical Volume: lvdisplay /dev/vo/myvol 2. Increase the Size of the Logical Volume: lvextend -L+121M /dev/vo/myvol 3. Make Available the size on online: ext2online /dev/vo/myvol 4. Verify the Size of the Logical Volume: lvdisplay /dev/vo/myvol 5. Verify that the size comes in online or not: df -h We can extend the size of the logical Volume using the lvextend command.
