Exam : Symantec 250-422
Title : Design & Custom. of HA Solutions for UNIX using VCS 4.1
1. 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
2. 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
3. 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
4. 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
5. 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
6. 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
7. 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
D.public IP addresses
Answer: D
8. 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
9. 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
10. Click the Exhibit button.
The diagram shows a customer's proposed HA configuration.
How do you address an obvious single point of failure?
A.add disk-based heartbeats
B.add HBAs for channel failure
C.add disks for OS disk mirroring
D.add a low priority heartbeat to public NICs
Answer: C
11. 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
12. 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
13. 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
14. 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
