Oracle Database 10g R2: Administering RAC Sample Questions:

Question 1

Because of the increasing load on your Oracle Database 10g Release 2 cluster, your company has decided to add one extra node to your existing four-node cluster. To prevent errors during this process, you want to make use of the Cluster Verification Utility (CLUVFY) so that you can check if you meet all requirements before you execute each step in this node-adding process. From where can you run CLUVFY?

A. from the Oracle Clusterware distribution media, any available RAC and/or CRS ORACLEJHOME on your cluster, and from the location where you downloaded it from in the Oracle Technology Network (OTN) Web site
B. from the Oracle Clusterware distribution media, any ORACLEJHOME on the node from which you installed the first four nodes, and from the location where you downloaded it from in the Oracle Technology Network (OTN) Web site
C. only after downloading it from the Oracle Technology Network (OTN) Web site
D. only from the Oracle Clusterware ORACLEJHOME
E. from both the Oracle Clusterware distribution media and the Oracle Clusterware ORACLEJHOME
F. only from a non-Oracle Clusterware ORACLEJHOME
G. only from the Oracle Clusterware distribution media

Question 2

Your company asked you to implement RAC to enhance the scalability and availability of the database that you manage. Your coworker suggested that you use ASM as the only storage option. However, you implemented RAC with Automatic Storage Management (ASM) as well as OCFS as storage options. What are the reasons for implementing both OCFS and ASM as storage options? (Choose all that apply.)

A. You want to use the Oracle Managed Files (OMF) feature but that is not supported by ASM.
B. You require OCFS to store archive log files because ASM does not support these files.
C. You do not want to store any file other than voting and OCR files in ASM.
D. You do not want to use raw devices to store voting and OCR files.
E. You want to avoid keeping Oracle binaries on local storage.

Question 3

Over a six-month period, you have been regularly monitoring your four-instance RAC database,
which is running on the first 4 nodes of a 6-node cluster, by using ADDM and by monitoring well-
known combinations of wait event and statistics in AWR reports.
Two weeks ago, a newer version of your main application went live. Starting last week, you
noticed a large increase in CPU time (consumed by the three application services on your RAC
database) due to increased workload.
The OLTP and DSS services have not had a decrease in the percentage of time spent using CPU.
However, for the BATCH service the percentage of time spent using CPU has gone down and the
wait-time percentage has increased.
You want to recommend a tuning exercise to your team. Which two recommendations would you
make first, based on the symptoms described? (Choose two.)

A. The BATCH service programs may scale well and could benefit from adding new database instances on either node 5 or 6, or on both.
B. The OLTP and DSS service programs may scale well and could benefit from adding new database instances on either node 5 or 6, or on both.
C. Tune SQL from the BATCH service programs because they may benefit from SQL tuning.
D. Tune SQL for the OLTP and DSS service programs because they may benefit from SQL tuning.
E. The OLTP and DSS service programs may scale well and could benefit from adding new database instances on one or both of nodes 5 and 6, and by adding more nodes the SQL for BATCH service programs would perform better due to more CPU power.

Question 4

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

A. 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.
B. Each primary RAC instance must send its redo stream to the same standby RAC instance.
C. 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.
D. When you have a serious crash of your primary site, Data Guard Broker automatically initiates the failover to the standby site.
E. You can have multiple RAC instances apply standby redo log files to the standby database.

Question 5

Your company has certain standard practices for technology and you are configuring ASM disk groups for your four-node RAC cluster. The company guidelines suggest that there is one disk group for the flash recovery area that is shared by all databases and a separate disk group for the database area of all databases. Which three exceptions exist that may require you to create additional disk groups? (Choose three.)

A. Some databases operate in ARCHIVELOGMODE and others in NOARCHIVELOGMODE.
B. Applications using the databases have different Service-Level Agreements for response time and throughput.
C. The disk farm has different disk models with different characteristics and ages.
D. The retention policy for backups are different for different databases.
E. There are large nonpartitioned tables accessed frequently using indexes.
F. There are partitioned tables where the older partitions are in read-only tablespaces and seldom accessed, but the more recent partitions are frequently accessed.
G. Some database instances are shut down every night while others are always running.
