1. For which two server metrics can you define thresholds for your services? (Choose two.)

A) APPLICATION_WAIT_TIME
B) PHYSICAL_READ_PER_CALL
C) LOGICAL_READ_PER_CALL
D) ELAPSED_TIME_PER_CALL
E) SQL EXECUTE ELAPSED TIME
F) CPU_TIME_PER_CALL

2. You need to add a new service to your RAC database, called DBA, to account for all the work done by database administrator sessions performing routine maintenance, to make this visible in the v$service_stats view. The maintenance would be done at quieter times but restricted session is not an option due to round-the-clock access requirements. The database administration team may connect locally or remotely to the RAC database. You decide to use DBCAto create the new service.
What must be true to allow client-server connection to the DBA service? (Choose two.)

A) The TNSNAMES.ORAfile or a name server must contain the net service entries for the DBA service.
B) The service must be started using the DBMS_SERVICE.START_SERVICE procedure.
C) The services must be started using the SRVCTL START SERVICE command.
D) The service must have at least one preferred or available instance that is running and accepting logins.
E) The ALTER SYSTEM REGISTER command must be used to induce PMON to register the service with the listeners.
F) All the listeners must be reloaded using LSNRCTL RELOAD to recognize the dynamically created service.

3. While creating a new service inside your ORCL database, you encounter a problem during the execution of the srvctl add service command. Because you are unable to explain the reason for this failure, you decide to log a service request in Oracle Metalink. You want to make this service request as complete as possible. You want to create a trace file from your problematic srvctl command execution so that Oracle Support has all possible information to quickly identify and resolve your problem. How do you create a Java-based tool trace file?

A) Request extra information by adding the -v (verbose) command-line flag at the srvctl command line.
B) Set the DEBUG environment variable to TRUE before you execute the srvctl command.
C) Request extra information by adding the -d (debug) command-line flag at the srvctl command line.
D) Set the SRVM_TRACE environment variable to TRUE before you execute the srvctl command.
E) Set the SRVM_DEBUG environment variable to TRUE before you execute the srvctl command.

4. Which three statements about deleting instances from a RAC database on a UNIX platform are true? (Choose three.)

A) To delete an instance, start the DBCA on a node other than the node that hosts the instance that you want to delete.
B) During a delete operation, the DBCA removes the instance and the instance Oracle Net configurationDuring a delete operation, the DBCA removes the instance and the instance? Oracle Net configuration.
C) To delete an instance, start the DBCA on the node that hosts the instance that you want to delete.
D) The DBCA can be used to delete an instance from a RAC database.

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