Oracle Database 10g R2: Administering RAC Sample Questions:

1. Several steps must be followed to successfully add a new node to your cluster database. Assuming that a UNIX platform is used, which of the three steps below are correct? (Choose three.)

A) Add the node to the cluster using the addnode.sh script run from ORA_CRS_HOME.
B) Reconfigure listeners for the new node with netca.
C) Add the RAC software to the new node using addnode.sh from ORA_CRS_HOM
D) Add instances using OUI.
E) Configure the OS and hardware for the new node.

2. You want check whether the group services node application is running on all the nodes in your cluster before you create a cluster database. Which utility can you use to make sure the node application is running on all nodes in the cluster?

A) Isnrctl
B) crsctl
C) onsctl
D) crs_stat
E) addnode.sh

3. 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 and one of the cluster ASM instances are currently unavailable. You also see 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 system boot, 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 not started by CRS because its target state was set to "offline" a while before the system was rebooted.
B) The database instance autostart attribute is set to a value, thus preventing CRS from starting it after a system reboot.
C) The database instance could not be started by CRS because this instance depends on an ASM instance, whose autostart attribute indicates that CRS should not start this ASM instance after system boot.
D) The instance was started by CRS after the system was rebooted, but someone stopped it from within SQL*Plus.
E) The instance was started by CRS but due to multiple instance failures CRS disabled the database instance, thereby preventing further restarts.

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

5. What does server-side Connect-Time Load Balancing do to complement the client-side Connect-Time Load Balancing function of balancing the connection requests to all the listeners in the address list on the client side?

A) it balances the load for each service across all preferred instances for all services, according to the service-specific load-balancing requirements,
B) it balances the load for each service across all preferred instances for that service, according to the global load-balancing requirements.
C) it balances the load for each service across all preferred instances for that service, according to the service-specific load-balancing requirements,
D) it balances the load for each service across all available instances for that service, according to service-specific load-balancing requirements,
E) it balances the load for each service across all instances for that service, according to the service-specific load-balancing requirements,
