Which three are true about disabling of the Data Guard Broker management of databases in a configuration and the effects of doing this? (Choose three.)

• A.A standby database that is the fast start failover target, may be disabled from broker management only by using the disable database DGMGRL command.
• B.The only way to disable broker management of a far sync instance is to use the disable configuration DGMGRL command.
• C.Database properties may be modified when that database is disabled from broker management.
• D.The configuration transport mode may be modified while the entire configuration is disabled from broker management.
• E.The only way to disable broker management of the primary database is to use the disable configuration DGMGRL command.

Which three steps are prerequisites for the creation of a physical standby database on a separate server using the RMAN active database duplication method? (Choose three.)

• A.Startup nomount the standby database instance.
• B.Set the DB_UNIQUE_NAME parameter on the primary database to a different value than that of the DB_NAME parameter.
• C.Configure Oracle Net connectivity on the primary host to the standby database instance.
• D.Put the primary database into archivelog mode.
• E.Establish user equivalence for the database software owner between the primary host and standby host.

Your Data Guard environment has a remote physical standby database with real-time query enabled, which is used for reporting, and a logical standby database used for DSS reporting.
Switchovers or failovers are possible due to testing or in case of a disaster.
Clients use local TNSNAMES.ORA files to define connection strings to the database instances.
Which three will prevent clients from connecting to the wrong database instances? (Choose three.)

• A.Oracle Net connectivity to the primary database instance must be established on all the standby database instances.
• B.The standby database services must be defined statically with the Listeners running on the standby database hosts.
• C.The client applications must use the correct TNS entries when requesting connections to the database instances.
• D.The LOCAL_LISTENER parameter on the primary database instance must always be set.
• E.A service name is registered with the local listener of each database instance.
• F.The DB_NAME and DB_UNIQUE_NAME parameters must be set to the same value for all the databases in the Data Guard environment.
• G.Client TNS entries for the databases use the correct service names for the intended service.

You administer a Data Guard environment consisting of a primary database and three physical standby databases.
One physical standby database is used for disaster recovery, one is used for reporting, and one is used as a replica for testing.
The standby database used for testing is occasionally converted into a snapshot standby database and then converted back to a physical standby.
The physical standby database is the only standby that is a mandatory destination.
The broker configuration operates in MAXIMUM PERFORMANCE mode.
Which ARCHIVELOG DELETION POLICY should be set, so that archive logs generated on the primary database are not deleted before they are consumed appropriately on each of the standby databases, but which allows them to be deleted form the primary as soon as it is safe to do so?

• A.CONFIGURE ACHIVELOG DELETION POLICY TO SHIPPED TO ALL STANDBY;
• B.CONFIGURE ACHIVELOG DELETION POLICY TO APPLIED ON STANDBY;
• C.CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;
• D.CONFIGURE ACHIVELOG DELETION POLICY TO SHIPPED TO STANDBY;
• E.CONFIGURE ACHIVELOG DELETION POLICY TO NONE;

A data file on one of your physical standby databases has been accidentally deleted and you must restore and recover it.
All the archive logs required for recovery are still on disk in the directory pointed to by the log_archive_dest_1 parameter.
Which three steps must be performed to restore the missing file and recover the standby database while it is in the MOUNT state? (Choose three.)

• A.Recover the database by using the RMAN RECOVER DATABASE command.
• B.Recover the datafile by using the RMAN RECOVER DATAFILE command
• C.Restore the datafile by using the RMAN RESTORE DATAFILE command.
• D.Restart the redo apply.
• E.Stop the redo apply.
