Oracle Database 10g R2: Administering RAC Sample Questions:

1. You are about to build a new Oracle Clusterware-based cluster and you want to make the installation process as smooth as possible. You decide to use the Cluster Verification Utility (CLUVFY) to check whether or not your system administrator has set up the hardware and system software correctly. Which two statements about CLUVFY are true? (Choose two.)

A) You have to install CLUVFY on all cluster nodes in order to use CLUVFY on other nodes than the one from which you perform the installation.
B) After the Oracle Clusterware installation, you can run CLUVFY from the Oracle Home that holds the CRS binaries.
C) CLUVFY cannot be used until the Oracle Clusterware is installed successfully.
D) To use CLUVFY during the Oracle Clusterware installation, you have to download CLUVFY from the Oracle Technology Network (OTN) Web site and install it before you can use it.
E) You can run CLUVFY only from a privileged operating system account.
F) You can run CLUVFY directly from the Oracle Clusterware distribution media.

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

3. View the Exhibit and examine an installation step of Oracle Enterprise Manager Grid Control 10gR2 to manage your RAC installation. You entered the host name but you are not sure about the port number. Thefollowing is the list of port numbers from the host ed-otraclin17b.us.oracle.com:

A) 1521
B) 5561
C) 1158
D) 4889
E) 3938

4. You have migrated your 10g R1 cluster to 10g R2. You wish to create multiple copies of the voting disk. What must you consider when doing this?

A) For the voting disk, it is better to rely on multipathing solutions instead of multiplexing.
B) Since ASM is the stated direction of Oracle, ASM is the best storage for voting disks.
C) If multiplexing, three voting disks on independent devices is ideal.
D) If multiplexing, two voting disks on independent devices is ideal.

5. Which three statements are true regarding RAC instance startup and shutdown using SQL'Plus? (Choose three.)

A) You can start multiple instances from a single SQL*Plus session on one node using Oracle Net Services connection strings.
B) It is not possible to start up or shut down more than one instance at a time in SOL*Plus. so you cannot start or stop all the instances for a cluster database with a single SQL*Plus command.
C) Using SQL*Plus to start and stop the RAC database instances is the preferred method because SQL*Plus is a Clusterware client.
D) To start or shut down your local instance, initiate a SQL*Plus session connected as SYSDBA or SYSOPER, and then issue the required command.
