Question No. 1

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.

Question No. 4

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:
: Oracle Database 19c Release 19.3 New Features, Dynamic Services Fallback Option1
: Automatic Failback of a Service in a Oracle-19c-RAC-Database2

Question No. 5

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.)

AIt fails because the ASM instance has not been shut down first on HOST03.

BIt succeeds and starts an ASM instance on HOST02 but the ASM instance on HOST03 is not shut down until all connected clients disconnect.

CIt succeeds and starts an ASM instance on HOST02 and shuts down the ASM instance on HOST03.

DIt succeeds and 19c database instances connected to the ASM instance on HOST03 can be reconnected to the ASM instance on HOST02.

EIt succeeds and 19c database instances connected to the ASM instance on HOST03 can be reconnected to the ASM instance on HOST01.

FIt fails because an ASM instance is not configured to run on HOST02.
