Which two are true about the use of RMAN recovery catalogs when offloading backups to a physical standby database? (Choose two.)

• A.It backups that are offloaded to a physical standby database are taken when not connected to a recovery catalog, then they may still be used for restoration on the primary database.
• B.The primary and physical standby databases must be registered separately in the recovery catalog, if a far sync instance is used to route redo to the physical standby database.
• C.The physical standby database may be used to register the database in the recovery catalog, if the primary is not registered.
• D.It is not necessary to use a recovery catalog unless a far sync instance is used to route redo to the physical standby database.
• E.Primary and physical standby database may use different virtual recovery catalogs in the same physical recovery catalog.

Which three are among the various tasks performed by the Data Guard Monitor (DMON) process? (Choose three.)

• A.communicating with the DMON process of the observer to monitor a primary database in case a fast start failover is required.
• B.maintaining information about all members of the broker configuration in binary configuration files
• C.activating role-based services appropriately in the various database instances of the configuration, based on the database role
• D.performing role transitions when switchover requests are made
• E.communicating with DMON processes in other database instances that are part of the broker configuration

You are required to change the Data Guard Configuration protection mode from MAXPERFORMANCE to MAXAVAILABILITY using Enterprise Manager Cloud Control.
Which two are true about this change? (Choose two.)

• A.Real time apply will be automatically turned on.
• B.Fast start failover can be enabled when making the chance.
• C.The primary database instance will remain up and running, if it cannot write redo to at least one synchronized standby database.
• D.Transactions will not commit until all redo data needed to recover those transactions are written to the online redo log, and to the standby redo log on at least one synchronizes standby database.
• E.If the primary database cannot write its redo to at least one synchronized standby database, then the protection level remains unchanged.

Which statement is true regarding Oracle Net connectivity for a Data Guard Broker configuration?

• A.A TNS enabling connectivity to the primary database instance must be defined on each of the standby database hosts.
• B.the LOCAL_LISTENER initialization parameter must be set to the listener used to register the primary database instance.
• C.To start SQL apply on a logical standby database, a TNS entry enabling connectivity to the primary database instance must be defined on the logical standby database host.
• D.A TNS entry or entries enabling connectivity to standby database instance(s) must be defined on the primary database host.
• E.To enable Real_Time Query on a physical standby database, a TNS entry enabling connectivity to the standby database instance must be defined on the primary database host.

You have a Data Guard Broker configuration called 'Somewhere' as shown:
DGMGRL> SHOW CONFIGURATION;
Configuration Somewhere
Protection Mode: MaxPerformance
Databases:
Nearby Primary database
FS Far Sync
Farout Physical standby database
Fast-Start Failover: DISABLED
Configuration Status:
SUCCESS
You then run this command:
DGMGRL > SHOW DATABASE 'Nearby' 'InconsistentProperties';
Which two are true about the output of this DGMGRL command? (Choose two.)

• A.Any inconsistency reported is on an instance-specific basis.
• B.It shows all properties whose broker configuration values for database Nearby are inconsistent with the values in the corresponding server parameter file or the runtime values for database instance Nearby.
• C.A far sync instance cannot have inconsistent properties because it has no database.
• D.It shows all properties whose broker configuration values for database Nearby are inconsistent with the broker configuration values for database Farout.
