In which two cases is it possible to change the protection mode to maximum protection using Enterprise Manager Cloud Control? (Choose two.)

• A.A logical standby database is the only standby database in the data guard configuration.
• B.A far sync instance is the only Data Guard configuration member receiving redo in synchronous mode.
• C.The primary and standby databases are hosted on different operating systems.
• D.Flashback is not enabled for either the primary database, the standby database, or both in the Data Guard configuration.
• E.A snapshot standby database is the only standby database in the Data Guard configuration.

Which three are true about the use of the VALID_FOR clause of the LOG_ARCHIVE_DEST_N parameter, in determining whether archive logs should be written to a particular destination by a database in a Data Guard environment? (Choose three.)

• A.whether the database at the destination is reached by using a far sync instance
• B.whether the database at the destination is a primary or a standby
• C.whether online redo logs are to be archived at a specific destination
• D.whether the database at the source is a primary or a standby
• E.whether standby redo logs are to be archived at a specific destination

Your Data Guard environment has two remote physical standby databases.
Client applications use the local naming method to connect to the primary database instance.
You want applications to automatically connect to the new primary database instance in case of a switchover or a failover.
Which will fulfill this requirement?

• A.Set the INSTANCE_NAME parameter identically on all databases; modify the connection descriptor on client applications to include all the standby hosts and connect to the database instance using that service name.
• B.Set the DB_NAME and DB_UNIQUE_NAME identically on all databases; modify the connection descriptors on client applications to include all the standby hosts and connect to the database instance using that service name.
• C.Create a database service on the primary database that is started automatically by a trigger, when the database role is PRIMARY; modify the connection descriptors used by client applications to include all the standby hosts and connect to the database instance using that service name.
• D.Create a database service on each standby database that is started automatically by a trigger, when the database role is PRIMARY; modify the connection descriptors used by client applications to include all the standby hosts and connect to the database instance using that service name.

Examine the Data Guard configuration:
DGMGRL> show configuration;
Configuration - Animals
Protection Mode: MaxAvailability
Databases:
dogs - Primary database
cats - Physical standby database
sheep - Logical standby database
Fast-Start Failover: DISABLED
Configuration Status:
ORA-01034: ORACLE not available
ORA-16625: cannot reach database "dogs"
DGM-17017: unable to determine configuration status
Which three will be true after a successful failover to Sheep? (Choose three.)

• A.The configuration will be in Maximum Availability mode.
• B.The configuration will be in Maximum Performance mode.
• C.Dogs will be in the disabled state and must be manually re-created.
• D.Dogs will be in the disabled state and must be manually reinstated.
• E.Cats will be in the disabled state and must be manually re-created.
• F.Cats will be in the disabled state and must be manually reinstated.

Which two statements are true about block media recovery in a Data Guard environment? (Choose two.)

• A.DB_LOST_WRITE_PROTECT must be set to FULL to enable Automatic Block Media Recovery.
• B.DB_LOST_WRITE_PROTECT must be set to TYPICAL to enable Automatic Block Media Recovery.
• C.When using RMAN, the RECOVER CORRUPTION LIST command can automatically use blocks from flashback logs.
• D.When using RMAN, the RECOVER CORRUPTION LIST command can use blocks from change tracking files.
• E.A corrupt block on the primary database can be recovered automatically, using blocks from a physical standby database that has the Real-Time Query enabled.
