When is fault-tolerance chosen over clustering? ExamSoon.com  The World Renowned  IT Certification Material Provider  Help you pass any IT Exams 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 ExamSoon.com  The World Renowned  IT Certification Material Provider  Help you pass any IT Exams D.public IP addresses Answer: D 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 12. 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 ExamSoon.com  The World Renowned  IT Certification Material Provider  Help you pass any IT Exams C.add disks for OS disk mirroring D.add a low priority heartbeat to public NICs Answer: C 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 ExamSoon.com  The World Renowned  IT Certification Material Provider  Help you pass any IT Exams D.the application and database file systems E.the application and database disk groups F.the application and database volume manager private regions Answer: ABDE 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.
