Question 6

You are planning to perform block comparison using the dbms comp package:

Which TWO statements are true?

A.The databases should be at least mounted before block comparison.

B.Logical standby databases can be the target database for the dbms_dbcomp.dbcomp procedure.

C.It requires that the DB_LOST_WKITE_protect initialization parameter be enabled.

D.You can monitor the progress of an ongoing block comparison operation by querying VS SES SION_LONGOPS.

E.It can be used to detect lost writes and inconsistencies between the primary database and the cascaded standbys.

Question 7

Which THREE are true about using flashback database in a Data Guard environment?

A.When a flashback database operation is performed on a primary database, a logical standby database is also flashed back automatically.

B.You can use it when real-time apply is enabled in case the physical standby suffers from logical corruption.

C.You can use it when real-time apply is enabled in case the phylt may not be used to flash back a primary database after a failover to a logical standby.

D.It may not be used to flash back a primary database after a failover to a physical standby.

E.It may be used to flash back a physical standby that receives redo from a far sync instance.

F.When a flashback database operation is performed on a primary database, a physical standby database is also flashed back automatically.

Question 8

You are monitoring your Data Guard broker configuration and issue this set of DGMGRL commands:
DGMGRL> SHOW CONFIGURATION;
Configuration - DRSolution
Protection Mode: MaxPerformance
Databases:
Close_by - Primary database
FS_inst - Far Sync
Far_away - Physical standby database
Fast-Start Failover: DISABLED
Configuration Status:
SUCCESS
What is true concerning this configuration?

A.The FS_inst Far Sync instance forwards redo to the Far_away physical standby only if the Close_by primary database is not able to do so.

B.The Close_by primary database forwards redo to the Far_away physical standby directly and also sends redo to the FS_inst Far Sync instance.

C.The Far Sync instance will not forward redo to the Far_away physical standby because Fast-Start Failover is disabled.

D.The Far Sync instance will not forward redo to the Far_away physical standby because the Protection mode is not MaxProtection.

E.The Close_by primary database instance forwards redo to the FS_inst Far Sync instance, which forwards the redo in turn to the Far_away physical standby database instance.

Question 9

Which THREE are always benefits of using a logical standby database?

A.It provides a disaster-recovery solution with switchover and failover options that can recover any data updated on the primary database.

B.It can be used for reporting workloads requiring additional indexes or materialized views or both.

C.It can be used for testing patchsets without affecting the primary database.

D.It can be used for database rolling release upgrades.

E.It can be used to replicate a single pluggable database (PDB) in a multitenant container database.

F.It can be used as an updatable database for Real Application Testing and then converted back to a standby database without affecting the updates.

Question 10

Which TWO are benefits of using Transaction Guard in a Data Guard environment?

A.It protects against user errors being replicated to standby databases.

B.It provides application continuity by rolling back uncommitted transactions interrupted by a failover or switchover.

C.It protects against logical corruptions being replicated to standby databases.

D.It protects against recoverable errors during a planned or an unplanned outage of a primary database.

E.It provides application continuity by replaying transactions interrupted by a failover or a switchover
