問題 #1

Your network administrator wants to know why you need extra IP addresses for your Oracle Real Applications Cluster now that you are upgrading from OracleSi to Oracle 10g. Which four statements would you use to explain to your network administrator the reason for requiring extra IP addresses? (Choose four.)

A. The VIPs should not be registered in the DNS.
B. The VIPs are used to prevent connection request timeouts during client connection attempts.
C. The VIP addresses must be on the same subnet as the public host network addresses.
D. The VIPs should be registered in the DNS.
E. A VIP would always accept a connection from a client.
F. A VIP would notify its client when a failure occurs.
G. The VIPs are used to circumvent network timeouts on the Cluster Interconnect.
H. Database clients should connect to a RAC database using VIPs for the best High Availability solution.

問題 #2

Which two statements are true regarding high availability in a RAC environment? (Choose two.)

A. Each primary RAC instance must send its redo stream to the same standby RAC instance.
B. When you have a serious crash of your primary site, Data Guard Broker automatically initiates the failover to the standby site.
C. When you have a serious crash of your primary site, it is your responsibility to initiate the failover to the standby site in case you are not using the Fast-Start Failover feature.
D. It is the Data Guard Broker's responsibility to communicate with CRS during a switchover operation to stop and start services according to each Data Guard site role.
E. You can have multiple RAC instances apply standby redo log files to the standby database.

問題 #3

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

問題 #4

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

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

問題 #5

View the Exhibit.
You are asked to help a colleague to logically remove node NLEDUC2 from a RAC cluster

which five additional steps would you recommend? Do not be concerned with the correct
sequence for the steps.
(Choose five.)

A. Stop and restart the nodeapps on NLEDUC1.
B. Stop and restart the clusterware on NLEDUC1.
C. Check that the database and ASM instances are all terminated on NLEDUC2.
D. Remove the listener from NLEDUC2.
E. Check that the ONS configuration has been updated on the remaining node.
F. Remove the node from the clusterware.
G. Check that the software has been removed from the database and ASM homes on NLEDUC2.
H. Check that the node has been removed from the database and ASM inventories.
