Your storage administrator informs you about some disk corruption issues in the disk subsystem where your Oracle Cluster Registry (OCR) is located. Your storage administrator has resolved these corruption issues by applying a patch to the storage subsystem, but to be sure that the OCR is not affected by this problem the administrator wants you to check the integrity of the OCR. How would you do this?

• A.You create a physical backup of the OCR by using the OCRCONFIG command, and if this succeeds without errors you know that the OCR is not corrupted.
• B.You dump the OCR contents into a text file by using the OCRDUMP command, and if that succeeds without errors you know that your OCR is not corrupted.
• C.You create a logical export from the OCR by using the OCRCONFIG command and analyze the export file for errors.
• D.You can check whether the OCR is not corrupted by using the OCRCHECK command.
• E.There is no easy way to check your OCR for corruptions.

You are asked to design a Maximum Availability Solution for a RAC configuration that provides for continuous availability for the Oracle database and which can survive instance failures, node failures, data failures, and site failures. The RAC configuration has a four-node cluster with five different services configured. Performance must be maintained for any failure situation for all the services, and all data must be preserved. All the servers in the configuration will have the same hardware. Which configuration would you recommend?

• A.Asymmetric RAC and a Physical Standby Database in a Dataguard configuration with RAC and ASM at all sites with the same number of instances but different service preferences
• B.Asymmetric RAC and a Logical Standby Database in a Dataguard configuration with RAC and ASM at all sites with the same number of instances but different service preferences
• C.Asymmetric RAC and Dataguard configuration with a mixture of RAC and single instances using ASM at all sites with the same service preferences
• D.Symmetric RAC and a Physical Standby Database in a Dataguard configuration with RAC and ASM at all sites with the same number of instances and the same service preferences

Which three storage types are suitable as a flash recovery area for an Oracle 10g RAC database? (Choose three.)

• A.Shared NFS directory
• B.Raw volume
• C.ASM disk group
• D.Local file system
• E.Cluster file system

View the Exhibit, which displays a portion of an ADDM report from a RAC database. Which three statements are true? (Choose three.)

• A.The ADDM report output reveals a "hot block" condition.
• B.The SQL statement with the ID dqsu2hwys8rcf was executed 40000 times
• C.The Findings Path section indicates that the Cluster wait class is consuming a significant proportion of the database time.
• D.A LOCK TABLE statement is causing excessive inter-instance messaging.

After migrating from a 10g R1 cluster to 10g R2, you decide to multiplex your voting disk. Which are the two ways in which you can accomplish this task? (Choose two.)

• A.You may use the VIPCA utility to add new voting disks.
• B.You should not use symbolic links.
• C.You may use the command:
  crsctl add ess votedisk <new voting disk path>
• D.You must add additional voting disks offline.
• E.You can add additional voting disks online.
