View the Exhibit.
Users complain about the performance of an Oracle database-based application. You are requested to investigate. From Grid Control, you immediately infer that one of the cluster database instances is currently unavailable. You also notice that the host where the instance belongs was recently rebooted due to an unknown reason.
Using Grid Control, you restart the instance and performance rapidly improves. You want to determine the cause of the instance startup failure after the system reboot, and you check the resource profiles on both the database and ASM instances involved.
Why was the instance not started by CRS?

• A.The instance was started by CRS after the system was rebooted, but someone stopped it from within SQL*Plus.
• B.The instance could not be started by CRS because this instance depends on an ASM instance, which has its autostart attribute set to a value, thereby preventing CRS from starting this ASM instance after a system reboot.
• C.The instance was started by CRS but due to multiple instance failures CRS disabled the database instance, thereby preventing further restarts.
• D.The database instance's autostart attribute indicates that CRS should not restart it after system boot.
• E.The instance was not started by CRS because its target state was set to "offline" before the system was rebooted.

According to the Maximum Availability Architecture, which case is best?

• A.Run two identical sites with a primary RAC database on the first site, and non-RAC physical and logical standby databases on the second site.
• B.Run two identical sites with a primary RAC database on the first site, and only a RAC logical standby database on the second site.
• C.Run two identical sites with a primary RAC database on the first site, and RAC physical and logical standby databases on the second site.
• D.Run two identical sites with a primary RAC database on the first site, and only a RAC physical standby database on the second site.

Which three statements regarding backup of the voting disk are true? (Choose three.)

• A.Whenever a voting disk backup is made, the Clusterware software should be stopped on all nodes in the cluster.
• B.A backup of the voting disk should be taken whenever an existing node is removed from the cluster.
• C.On UNIX platforms, the voting disk can be backed up with the dd command.
• D.A backup of the voting disk should be taken whenever an RMAN catalog reset is done.
• E.A backup of the voting disk should be taken whenever a new node is added to the cluster.

Which initialization parameter would you use for each RAC instance to make sure that each listener on each RAC node is aware of the load of all the others?

• A.REMOTE_DEPENDENCIES_MODE "
• B.PREFER LEAST LOADED NODE <listener-name>
• C.LOCALJJSTENER
• D.REMOTEJJSTENER

You and your colleague are working with Oracle Support on a database instance stability issue. The Oracle Support engineer wants you to issue a crsctl debug log crs ?crsctl debug log crs command to assist you in your troubleshooting assignment. Why does the Oracle Support engineer want you to do this?

• A.to enable extra debugging on the currently running CRS daemon
• B.to enable extra debugging on the currently running and CRS daemons as well as those that will run in the future
• C.to list which debugging options are enabled on the CRS daemon
• D.to enable extra debugging on the CRS daemon the next time the CRS daemon is started
• E.to list what debugging options are available on the CRS daemon
