Question 21

Which three statements are true concerning diagnostic components and requirements of Oracle 12c Clusterware? (Choose three.)

A. There is one ologgered service for the cluster health monitor (CHM) on each cluster node regardless of cluster size.
B. The Grid Infrastructure Management Repository database must run on a hub node if Flex Clusters are used.
C. There is one osysmond service for the cluster health monitor (CHM) on each cluster node regardless of cluster size.
D. The oclumon utility may be used to get and set parameters for the cluster health monitor (CHM) repository.
E. The diagcollection.pl script must be run from the Grid home directory as the Grid infrastructure owner.
F. The clusterware log files are stored inside the Grid Infrastructure Management Repository database used by the cluster health monitor (CHM).

Correct Answer:BCD
B: The Oracle Grid Infrastructure Management Repository Runs on one node in the cluster.This must be a Hub Node in an Oracle Flex Cluster configuration.
C: There is one system monitor service on every node. The system monitor service (osysmond) is a real-time, monitoring and operating system metric collection service that sends the data to the cluster logger service.
D: Use the oclumon manage command to view and change configuration information from the system monitor service.
Syntax
oclumon manage -repos {{changeretentiontime time} | {changerepossize memory_size}} | -get {key1 [key2 ...] | alllogger [-details] | mylogger [-details]}
Where changerepossize memory_size: Use this option to change the CHM repository space limit to a specified
number of MB.
Note: The OCLUMON command-line tool is included with CHM and you can use it to query the CHM repository to display node-specific metrics for a specified time period. You can also use OCLUMON to perform miscellaneous administrative tasks, such as changing the debug levels, querying the version of CHM, and changing the metrics database size.

Question 22

Which three statements are true about an Oracle Database RAC software installation? (Choose three.)

A. The software must be installed into a cluster le system.
B. The software must be installed into a local file system on each node.
C. RAC installations require Oracle Enterprise Edition.
D. Fix-up scripts generated during the installation must be run as root on UNIX platforms.
E. The software can be installed into an ACFS file system.
F. The software must be installed on all nodes in the cluster.
G. SSH user equivalence for the Oracle user can be set up before the software installation.

Correct Answer:DEG

Question 23

You administer a three-instance, policy-managed, multitenant RAC database CDB1 with three PDBs: PDB_1, PDB_2, and PDB_3.
You want to drop PDB_3.
Which two statements are true? (Choose two.)

A. PDB_3 must be closed on all CDB1 instances.
B. Manually created services for PDB_3 are not removed automatically from the OCR when dropping PDB_3.
C. CDB1 must be open in restricted mode on all cluster nodes.
D. PDB_3 must be open READ ONLY in all CDB1 instances.
E. Manually created services for PDB_3 are removed automatically from the OCR when dropping PDB_3.

Correct Answer:AE

Question 24

A Java application will be deployed, and you must configure a RAC database to support highly available connections.
The application will use the Universal Connection Pool (UCP), and Fast Connection Failover (FCF) must be enabled.
Which two statements are true? (Choose two.)

A. The application may use the JDBC thin driver.
B. The ons.jar file must be present in the CLASSPATH.
C. The ONS daemon must be started on the middle tier running the Java application.
D. You must configure TAF, either on the client or for the service.
E. The ONS daemon must be started on the middle tier and client machines to enable FCF.

Correct Answer:AE

Question 25

Which three statements are true concerning policy-based cluster management in Oracle 12c Clusterware?

A. Server Pools must be managed with the crsctl utility for servers hosting an application or other administrator-defined high-availability resource.
B. All servers in a new cluster installation belong to the generic server pool.
C. The server pool contains servers that host administrator-defined high availability resources.
D. Server pools must be managed with the srvctl utility for servers hosting a database.
E. All servers in a new cluster installation belong to the free server pool.

Correct Answer:CDE
C: Server pools divide the cluster into logical groups of servers hosting both singleton and uniform applications. The application can be a database service or a non-database application.
D: You manage server pools that contain Oracle RAC databases with the Server Control (SRVCTL) utility.
E: When Oracle Clusterware is installed, two internal server pools are created automatically: Generic and Free. All servers in a new installation are assigned to the Free server pool, initially
