3) It relies on storage hardware or host-based RAID functionality to support high availability.
4) It is a shared storage file system designed in such a way that you can avoid setting up of raw
partitions to store certain files.
Which file system corresponds to these features?

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

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 can check whether the OCR is not corrupted by using the OCRCHECK command.
• B.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.
• C.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.
• D.You create a logical export from the OCR by using the OCRCONFIG command and analyze the export file for errors.
• E.There is no easy way to check your OCR for corruptions.

Which statement is true regarding undo management in a RAC environment?

• A.You cannot mix automatic undo management and manual undo management.
• B.A RAC database must have defined only one undo tablespace for each instance.
• C.It is possible to store undo tablespaces on nonshared disks.
• D.A RAC database contains one undo tablespace shared by all instances.

You are requested to make your Web server, which accesses a clustered Oracle database, highly available. Which solution would you propose?

• A.Because you cannot use Oracle Clusterware to protect your Web server, you come up with an operating system solution.
• B.Bring your Web server under control of the Oracle Clusterware and use the RAC VIP address to reach your Web server from your clients.
• C.Bring your Web server under control of the Oracle Clusterware and use an application VIP address to reach your Web server from your clients.
• D.Bring your Web server under control of the Oracle Clusterware and use the public IP address to reach your Web server from your clients.
• E.Bring your Web server under control of the Oracle Clusterware and use the private IP address to reach your Web server from your clients.
