[All 1Z0-066 Questions]

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?

AThe 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.

BThe far sync instance will not forward redo to the Far_away physical standby because the Protection mode is not MaxProtection.

CThe close_by primary database forwards redo to the Far_away physical standby directly and also sends redo to the FS_inst Far Sync instance.

DThe far sync instance will not forward redo to the Far_away physical standby because Fast-Start Failover is disabled.

EThe 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.

Show Suggested Answer

Suggested Answer: A

An Oracle Data Guard far sync instance is a remote Oracle Data Guard destination that accepts redo from the primary database and then ships that redo to other members of the Oracle Data Guard configuration. A far sync instance manages a control file, receives redo into standby redo logs (SRLs), and archives those SRLs to local archived redo logs, but that is where the similarity with standbys ends. A far sync instance does not have user data files, cannot be opened for access, cannot run redo apply, and can never function in the primary role or be converted to any type of standby database.
