1. You have attended a user group presentation on RAC and based on what you have learned you feel that your company would benefit from having the RAC option to meet its Oracle database requirements in several ways. Your manager does not know much about RAC and asks you to create a presentation to the team explaining RAC, and whether it should be implemented in your installation. Which three statements explain the benefits and implications of RAC? (Choose three.)

A) RAC would increase availability in the event of data failures.
B) RAC used in conjunction with parallel execution may provide speedup of DSS queries.
C) RAC would increase scalability for all application workloads in all cases.
D) RAC alone would not help protect from human errors.
E) RAC would increase availability in the event of node and instance failures.
F) RAC alone would increase availability when doing release upgrades.
G) RAC would increase availability in the event of a network failure.
H) RAC used in conjunction with parallel execution may provide for speedup of OLTP workload processes.

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

3. Which background process communicates load information to its listener?

A) MMON
B) SMON
C) LMON
D) PMON

4. Your four-node RAC cluster is no longer coping with workloads for one of its databases at peak periods and you decide to add another node to the cluster. The current configuration has two RAC databases, each with four instances with only the second database using ASM as a clustered database file system. ASM is installed in a separate home. Which five steps must you take to add all the software components and processes to the new node before you run DBCAto add database and ASM instances on the new cluster nodes. Do not be concerned with the correct sequence for the steps. (Choose five.)

A) Run addnode.sh in the Clusterware home/oui/bin directory from each of the existing nodes once to define the new node to each existing node.
B) Run netca from the new node to add a listener to the new node.
C) Run addnode.sh in the Clusterware home/oui/bin directory from one of the existing nodes to define the new node to all existing nodes.
D) Run addNode.sh in the ASM home/oui/bin directory from one of the existing nodes.
E) Run cluvfy stage -pre crsinst <list of all nodes> from one of the existing nodes to verify the cluster configuration.
F) Run addNode.sh in the RDBMS home/oui/bin directory from one of the existing nodes.
G) Run racgons add_config from one of the existing nodes to add the ONS metadata to the OCR.

5. 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 can run CLUVFY only from a privileged operating system account.
B) 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.
C) You can run CLUVFY directly from the Oracle Clusterware distribution media.
D) After the Oracle Clusterware installation, you can run CLUVFY from the Oracle Home that holds the CRS binaries.
E) 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.
F) CLUVFY cannot be used until the Oracle Clusterware is installed successfully.
