문제4

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?

A. 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.

B. 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.

C. 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.

D. 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.

E. 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.

정답: C

문제5

C. One undo tablespace for each instance is required.

D. It requires the cdb to use shared undo management.

E. You can open one, several, or all PD3s on one, several, or all cdb instances.

F. One undo tablespace for each pdb is required.

정답: B,D,E

문제6

B. You must create a Grid Management Repository database.

C. DNS must be configured to delegate name resolution for the cluster subdomain to the cluster.

D. You must enable the Name Server Cache Daemon

E. Each cluster node must have at least two network interface cards.

F. A DHCP service on the private network for the cluster is required to allocate virtual IP addresses for HAIP.

정답: A,C,D

D. It runs automatically in Instance ADDM mode after each AWR snapshot is created.

E. It can only analyze performance on the instance running the ADDM job.

F. It can analyze performance using data captured on all instances.

정답: A,B,F

문제8

Which three statements are true regarding ASM on a four-node cluster? (Choose three.)

A. A database instance on a node can only be a client of an ASM instance running on the same node.

B. A database instance on a node cannot be a client of an ASM instance running on other nodes.

C. A database instance on a node can be a client of an ASM instance running on any node.
