1. Your systems use dynamic reconfiguration to reallocate hardware dynamically. The system and processes will continue normally after a reconfiguration. However, all processing on the system is stopped during the reconfiguration process. You do NOT want VCS to fault a system undergoing the dynamic reconfiguration operation. Which parameter would enable you to extend the time allowed before a systems VCS heartbeat times out? A.heartbeat B.peerinact C.heartbeatlo D.retrans Answer: B
2. You are designing a high availability solution where low cost is the primary design requirement. The HA solution must control two database servers. Each database server requires a virtual IP address and disk group in order to run and fail over properly. The performance of a system degrades significantly if it is required to run both database servers simultaneously. Which HA design do you recommend? A.a two-node active/active cluster B.a two-node active/passive cluster C.a three-node N+1 cluster D.a three-node N+2 cluster Answer: A
3. You are designing a cluster for a Web server. The Web server has mostly static data that infrequently changes. Your budget is limited and you want to minimize the cost of the cluster. Which storage solution best fits this criteria? A.shared storage B.local storage only C.replicated storage D.No storage is needed. Answer: B

4. You have a two-system cluster with a production application on one system and a test application on another. The test and production applications cannot run on the same system at the same time, and if the production application needs to fail over, the test application must be shut down first. Which category of service group dependency supports this behavior? A.Global B.Local C.Online D.Offline Answer: D
5. You want to validate operation after installing, configuring, and starting VCS. You execute the command gabconfig a. Which GAB ports should be running? (Choose two.) A.a B.c C.h D.s E.x Answer: AC
6. What is one disadvantage of using active/active clusters over using passive standby systems in a cluster? A.Active/Active clusters risk overloading the systems. B.Most applications will not support active/active clustering. C.Active/Active clusters increase operational overhead. D.Active/Active clusters increase the cost of licensing. Answer: A
7. When is fault-tolerance chosen over clustering?

A.when near zero downtime is required B.when you are only concerned with network subsystems C.when you are only concerned with storage subsystems D.fault-tolerance and VERITAS clustering are interchangeable. Answer: A
8. There is a business requirement to alert a help desk whenever any event affecting an application or the cluster occurs in a VCS cluster. What should be implemented in the HA design? A.configuration of the VCS notifier agent B.configuration of the AlertMonitor agent C.write a series of custom triggers D.provide the Help Desk with read-only GUI access Answer: A
9. There is a front-end application that should only accept client connections when a back-end database application is available. Both applications are to be made highly available under VCS in the same cluster. Which two ways can this be configured in VCS? (Choose two.) A.configure separate service groups for each application with no dependencies. B.configure separate service groups for each application with a dependency. C.configure one service group with appropriate dependencies between resources from each application. D.configure one service group with no dependencies between resources from each application. E.configure the notifier to start the front-end application after the back-end application has started Answer: BC
10. There is basic information available about an application environment including the hostname, applications installed, and location of hardware. What else needs to be known in order to configure VERITAS Cluster Server? A.the CPU serial number B.SCSI paths C.boot disk configuration

11. A database needs to be made highly available. There are currently two identical servers ten meters apart that are to be clustered. Which two pieces of additional information are needed in order to determine the high availability requirements? (Choose two.) A.the server operating system version B.LAN capacity C.the database version D.the client operating system version E.the distance between clients and the server Answer: AC

13. What is recommended for the implementation of a high availability environment? A.redundant hardware on the cluster systems B.a minimum of two service IP addresses per host C.a minimum of 10 GB of local disk space on each host D.an SNMP management application installed on shared storage Answer: A
14. You are designing a high availability solution. Transaction processing is the most important service of this application. Other services are not as important and can be down for short periods of time. Which component is NOT critical to this design? A.the application program that processes transactions B.the proprietary database used by the application program C.the file system that stores transactional data processed by the application D.the file system that stores reports generated by users Answer: D
15. You are implementing a new VCS cluster for a new application that includes a database. Both the application and database have to run on the same server at any given time. The application communicates with the database through proprietary interfaces that use shared memory. External users only connect to the application and never connect to the database directly. The storage is controlled by VERITAS Storage Foundation. Which four resources must be set to critical in VCS to ensure high availability of the application? (Choose four.) A.the application engine B.the database engine C.the database network listener

16. After a meeting with the system administrator, you have been tasked with designing a HA solution for an in-house application system. All applications in this system already have VCS agents available. The system has the following components: One database engine, which recommends 768 MB of system memory One in-house application named app1, which recommends 512 MB of system memory One in-house application named app2, which recommends 384 MB of system memory One in-house application named app3, which recommends 256 MB of system memory You are designing the solution for three nodes, each with one gigabyte of system memory. Which feature of VCS do you need to implement in the design? A.SystemLoad B.Limits C.Triggers D.Custom agent Answer: B
17. You are designing an HA solution for an application called WorkApp. Historically, your company has upgraded the version of WorkApp every six months. Management wants parts of the HA design to include the ability to validate the newest version of WorkApp before going into production. This has been difficult in the past because most upgrades require updating the applications data files. Which VERITAS product should be included in the design to accommodate this request? A.Data Change Map B.FlashSnap C.Bare Metal Restore D.Clustered Volume Manager Answer: B

Which component will need to be replaced if it exists in the current cluster? A.SAN-based disks containing application data B.parallel service groups C.host-connected SCSI disks containing application data D.I/O fencing Answer: C 19. You are the administrator of a set of three two-node VCS clusters. You have been asked to put together a design for changing this set to a single cluster of six nodes. Which component will need to be replaced if it exists in the current cluster? A.VLAN-based heartbeats B.failover service groups C.Clustered Volume Manager D.crossover heartbeat cables Answer: D
20. You are designing an HA solution and will use VERITAS Storage Foundation to store application data. You have a dynamic environment where you frequently need to grow or shrink file systems used by the application. How does this impact your HA design? A.This does not have any impact on the HA design. B.Although you can grow the file systems, you cannot shrink them after you put the application in an HA environment. C.Every time you grow or shrink a file system, you need to bring the application down. D.Every time you grow or shrink a file system, you need to modify the VCS configuration so that the corresponding Volume and Mount type of resources reflect the changes. Answer: A
