Question No. 2

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?

ASecurity 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.

BSecurity 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.

CSecurity 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.

DDatabase 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.

EDatabase 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.

BThe source PD3 must be in read only mode on all CD3 instances if the CDB is in No Archive mode.

CThe source pdb must use a global temporary

DIt can be executed only by a common user with the create pluggable database system privilege connected to the root container.

EOracle Managed Files must be enabled or PD3 file name convert must be set.

FAll running CDB instances must be open in restricted mode.

Question No. 5

Which statement describes the usage of Dynamic Service Fallback in Oracle RAC 19c?

ADynamic Service Fallback allows a service to relocate to an available instance when the service is stopped on a preferred instance.

BDynamic Service Fallback allows a service to fall back to a preferred instance when the available instance performance falls below a specified threshold after it was failed over to an available instance.

CTo enable Dynamic Service Fallback, you should specify the level of performance of a preferred instance for a service to be relocated to an available instance by setting the -fallback attribute of a service to 'Low, Medium, or High'.

DDynamic Service Fallback allows a service to fall back to a preferred instance when it becomes available after it was failed over to an available instance.
Dynamic Service Fallback allows a service to fall back to a preferred instance when it becomes available after it was failed over to an available instance. This is true because Dynamic Service Fallback is a new feature in Oracle RAC 19c that enables a dynamic database service to automatically relocate to a preferred instance when it is restored, after the service was failed over to an available instance due to the failure of the last preferred instance. This feature improves the availability and performance of the service by minimizing the manual intervention and the number of failovers.To enable Dynamic Service Fallback, you should specify the -failback option for the service as YES when using SRVCTL or DBCA12.Reference:
