Which THREE statements are TRUE about Global Sequences when connected to a physical standby database with Real-Time Query enabled?

• A.If the CACHE option is set then the size of the cache must be at least 100.
• B.Their usage will always have a performance impact on the primary database.
• C.They must have the NOORDEK and CACHE options set.
• D.Their usage may have a performance impact on the physical standby database if the CACHE size is too small.
• E.Their creation requires that a LOG archive_dest_n parameter be defined in the standby that points back to the primary.

Your expertise is requested for these customer requirements:
The Data Guard environment must be in maximum protection mode.
Reports must be offloaded to a physical standby database.
There must be no lag between the primary and standby databases that affect the reports produced.
The primary database must be resilient in case of a single network failure.
Which solution is correct for these requirements?

• A.One physical standby database with Real-Time Query enabled and STANDBY_MAX_DATA_DELAY parameter set to zero, receiving redo from the primary with synchronous transport
• B.Two standby databases, at least one of them a physical standby with Real-Time Query enabled and the STANDBY_MAX_DATA_DELAY parameter set to zero, receiving redo from the primary with synchronous transport
• C.Two physical standby databases with Real-Time Query enabled, receiving redo from the primary with the LOG_ARCHIVE_DEST_n attributes SYNC NOAFFIRM to minimize the performance impact on the primary
• D.Two standby databases, at least one of them a physical standby with Real-Time Query enabled and the STANDBY_MAX_DATA_DELAY parameter set to zero, receiving redo from the primary with asynchronous transport
• E.One physical standby database with Real-Time Query enabled, receiving redo from two Far Sync instances that are connected to the primary

You are licensed to use Oracle Active Data Guard.
Which TWO statements are true after enabling block change tracking on a physical standby database?

• A.It allows fast incremental backups to be taken on the primary database.
• B.It starts the RVWR process on the physical standby database instance.
• C.It allows fast incremental backups to be offloaded to the physical standby database.
• D.It allows fast incremental backups to be offloaded to a snapshot standby database, when the physical standby database is converted.
• E.It starts the CTWR process on the physical standby database instance.
• F.It starts the CTWR process on the primary database instance.

Examine the Data Guard configuration:
DGMGRL> show configuration;
Configuration - Animals
Protection Mode: MaxAvailability
Databases:
dogs - Primary database
cats - Snapshot standby database
sheep - Snapshot 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
ou wish to perform a failover to sheep. Which command, or sequence of commands, should you issue to the broker before executing failover to sheep; using the broker?

• A.None, because you can directly failover to a Snapshot Standby Database.
• B.DGMGRL> convert database cats to physical standby;
• C.DGMGRL> convert database sheep to physical standby;
  DGMGRL> edit configuration set protection mode as maxperformance;
  DGMGRL> convert database sheep to physical standby;
• D.DGMGRL> convert database sheep to physical standby;
• E.DGMGRL> convert database cats to physical standby;

Which three are true concerning database states after a successful switchover?

• A.If the former primary database became a physical standby database it will always be open readonly.
• B.If the former primary database became a physical standby database it will be in the same state as the former physical standby database.
• C.The former primary database will always be open.
• D.If the former primary database became a logical standby database it will be in mount state.
• E.If the former primary database became a logical standby database it will be open read-write.
• F.The new primary database will be open read-write.
