Question 20

Which three resources are managed using global concurrency control in an Oracle 19c RAC multi-instance database? (Choose three.)

Options:

Database block buffers

Mutexes

Redo log buffers

Latches

Enqueues

Cursors

Question 21

A cluster running 19c Grid Infrastructure supports both Oracle 11g to 19c RAC databases using ASM.

TheCOMPATIBLE.ASM,COMPATIBLE.RDBMS, andCOMPATIBLE.ADVMparameters are currently set to 11.2 for all diskgroups..

You must support these capabilities in all diskgroups:

1. ACFS Replication

2. ACFS Encryption

To what minimum values must the compatible attributes be set?

Options:

Set COMPATIBLE.ASM to 11.2, COMPATIBLE.RDBMS to 12.1, and COMPATIBLE.ADVM to 11.2.

Set COMPATIBLE.ASM to 12.1, COMPATIBLE.RDBMS to 12.1, and COMPATIBLE.ADVM to 12.1.

Set COMPATIBLE.ASM to 11.2, COMPATIBLE.RDBMS to 12.1, and COMPATIBLE.ADVM to 12.1

Set COMPATIBLE.ASM to 12.1, COMPATIBLE.RDBMS to 11.2, and COMPATIBLE.ADVM to 12.1.

Set COMPATIBLE.ASM to 11.2, COMPATIBLE.RDBMS to 11.2, and COMPATIBLE.ADVM to 11.2.

Question 22

You performed these steps to disable an ADVM volume containing an ACFS file system:

1. Dismount the file system.

2. Disable the volume with the ASMCMDvoldisablecommand.

Which two statements are true regarding the actions performed? (Choose two.)

Options:

The ACFS file system will be permanently removed from the volume.

The ACFS mount registry with Oracle restart is automatically deleted.

The disabling of volume does not destroy data in the file system.

The volume can be enabled and the file system can be mounted back again to access the existing data.

The ACFS file system will be permanently removed from the volume only if the file system is empty.

Question 23

Secure Cluster Communication protects the cluster interconnect from common security threats when used together with Single Network Support. Secure Cluster Communication includes message digest mechanisms, protection against fuzzing, and uses Transport Layer Security (TLS) to provide privacy and data integrity between the cluster members.

Which statement is true about securing cluster interconnect communication?

Options:

Security for the cluster interconnect is invoked automatically as part of a new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c and Database administrators or cluster administrators do not need to make any configuration changes for this feature.

Security for the cluster interconnect is invoked automatically as part of a new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c using an auto-generated encryption key that is stored locally on each node of the cluster in an Oracle Wallet and Database administrators or cluster administrators must provide a valid path for the Wallet file.

Security for the cluster interconnect is invoked by auto-generated server certificates that will be assigned to each cluster node as part of a new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c.

Database administrators or cluster administrators must provide an encryption key during new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c to secure the interconnect communication.

Database administrators or cluster administrators must provide a valid server certificate and an Oracle Wallet for each node during new Oracle Grid Infrastructure 19c deployment or an upgrade to Oracle Grid Infrastructure 19c to secure the interconnect communication.
