Which statement is true about Oracle Database 19c SGA Management?

• A.Oracle RAC Resource Management requires the same SGA value for all the instances of a RAC database which is configured during database startup only.
• B.Oracle RAC Resource Management only allows assignment of the SGA during database startup.
• C.Oracle RAC Resource Management only allows assignment of the SGA during instance startup.
• D.Oracle RAC Resource Runtime Management allows for automatic and runtime adjustment of the SGA.

You administer a six-instance, policy-managed, multitenant RAC database CDB1 with three PDBs: PDB_1,PDB_2, and PDB_3.
Server pool prod_pool has a cardinality of three and all six hosts of the cluster are up.
Examine these commands executed on HOST01:

Which two statements are true regarding the AR service? (Choose two.)

• A.AR is available on any one available CDBl instance in prod pool at any one time.
• B.AR can fail over to any one of the available CD31 instances.
• C.AR runs as a singleton service in the server pool prod pool and the AR service is available in each of the CDBl instances.
• D.AR is available only on the CDBl instance on host01.
• E.AR can fail over to any other available CDBl instance in prod pool.

Which two statements are true about High Availability NFS (HANFS)? (Choose two.)

• A.NFS client requests are distributed by DNS in a round-robin fashion to the cluster nodes that export the NFS
• B.HANFS does not depend on NFS services provided by the underlying operating system.
• C.HANFS provides high availability in case of cluster node failure.
• D.HANFS' performance depends on the characteristics of the underlying ASM disks.
• E.HANFS provides high availability in case of an NFS client failure.

Examine the output of the asmcmd and srvctl commands:

Then you execute this command:
$ srvctl relocate asm -currentnode host03 -targetnode host02
Which three statements are true regarding the execution of this command based on the output shown? (Choose three.)

• A.It fails because an ASM instance is not configured to run on HOST02.
• B.It fails because the ASM instance has not been shut down first on HOST03.
• C.It succeeds and 19c database instances connected to the ASM instance on HOST03 can be reconnected to the ASM instance on HOST02.
• D.It succeeds and 19c database instances connected to the ASM instance on HOST03 can be reconnected to the ASM instance on HOST01.
• E.It succeeds and starts an ASM instance on HOST02 but the ASM instance on HOST03 is not shut down until all connected clients disconnect.
• F.It succeeds and starts an ASM instance on HOST02 and shuts down the ASM instance on HOST03.

Examine this command:

Which two statements are required for this command to succeed? (Choose two.)

• A.The +DATA disk group should not be part of Flex ASM.
• B.Existing data files in TBS1 must also use the same template.
• C.The DB_CREATE_FILE_DEST parameter must be set to +DATA(newtemplate).
• D.newtemplate must be defined for the +DATA disk group.
• E.User-defined subdirectories ORCL and USERS must already exist.
