Oracle Database 19c: Data Guard Administration Sample Questions (Q31-Q36):

NEW QUESTION # 31
Which four factors can influence the rate of SQL apply on a logical standby database?

  • A. the number of full table scans performed by SQL apply
  • B. the number of coordinator processes on the standby database instance
  • C. the size of the shared pool
  • D. the number of applier processes
  • E. the size of the undo tablespace on the logical standby database
  • F. the number of PREPAER processes

Answer: A,B,D,F

Explanation:
The rate of SQL apply on a logical standby database can be influenced by:
A: The number of PREPARER processes (which seems to be a typographical error and should read as PREPARER or similar) which prepare the redo data for the applier processes.
B: The number of coordinator processes on the standby database instance which coordinate the SQL apply activities.
C: The number of full table scans performed by SQL apply since full table scans can be resource-intensive and slow down the apply rate.
E: The number of applier processes which apply the redo data to the logical standby database.
Option D is incorrect as the size of the undo tablespace on the logical standby database is more likely to affect the SQL apply lag rather than the rate of SQL apply.
Option F is incorrect because the size of the shared pool would typically not influence the rate of SQL apply. The shared pool is more related to the caching of shared SQL and PL/SQL code and control structures.


NEW QUESTION # 32
Which two Data Guard features require the use of flashback database by the broker?

  • A. Real Time Query
  • B. Read-Mostly physical standby implementations
  • C. Snapshot Standby databases
  • D. Far Sync Instances
  • E. Fast-Start Failover

Answer: C,E


NEW QUESTION # 33
Examine the Data Guard configuration:

Which three will be true after a successful failover to Cats?

  • A. Sheep will be in the enabled state.
  • B. Dogs will be in the disabled state and has to be manually reinstated.
  • C. The configuration will be in Maximum Performance mode.
  • D. The configuration will be in Maximum Availability mode.
  • E. Sheep will be in the disabled state.

Answer: A,B,D

Explanation:
After a successful failover to the 'cats' database in a Data Guard configuration:
B: Sheep, being another standby database, would typically remain in the enabled state unless specifically disabled or if there was a configuration issue.
D: Dogs, which was the primary database prior to failover, will be in a disabled state as part of the failover process. Manual intervention is required to re-establish 'dogs' as a standby database or to return it to the primary role through another role transition.
E: If the configuration was in Maximum Availability mode before failover, it would remain in this mode after failover, provided all settings were properly configured and no changes were made to the protection mode.
Option A is incorrect because failover does not automatically change the protection mode to Maximum Performance. The protection mode remains as it was prior to the failover unless manually altered.


NEW QUESTION # 34
Which two are prerequisites for configuring flashback database for Oracle 19c databases, in a Data Guard environment?

  • A. The data guard broker must be used.
  • B. A far sync instance must be configured to flash back a standby when the primary has been flashed back.
  • C. The database must be in ARCHTVELOG mode.
  • D. A fast recovery area must be configured.
  • E. The Data Guard real-time apply feature must be enabled.

Answer: C,D

Explanation:
* A fast recovery area must be configured (B): Flashback Database requires a fast recovery area to be set up because flashback logs are stored there. The fast recovery area is a unified storage location for all recovery-related files and activities.
* The database must be in ARCHIVELOG mode (C): Flashback Database operation relies on the ability to archive redo logs. Therefore, the database must be running in ARCHIVELOG mode for Flashback Database to be enabled.

NEW QUESTION # 35
