Oracle Database 19c: Data Guard Administration Sample Questions (Q40-Q45):

NEW QUESTION # 40
Active Data Guard (ADG) databases are widely used to offload reporting or ad hoc query-only jobs from the primary database. Reporting workload profile is different from the primary database and often requires tuning.
Which tool is used to tune SQL workloads running on an ADG database?

A. Standby Statspack
B. Automatic Diagnostic Database Monitor (ADDM)
C. Automatic Workload Repository (AWR)
D. SQL Tuning Advisor
E. In-Memory Active Session History (ASH)

Answer: C

Explanation:
AWR collects, processes, and maintains performance statistics for problem detection and self-tuning purposes.
In an Active Data Guard environment, where the physical standby database can be used for read-only workloads, AWR can be instrumental in identifying performance bottlenecks and areas for optimization. It provides detailed reports that include wait events, time model statistics, and active session history, making it an invaluable tool for tuning SQL queries and overall database performance in an ADG setup.

NEW QUESTION # 41
Which TWO are TRUE about offloading backups to a physical standby database in a Data Guard environment?

A. The standby database must be registered in an RMAN catalog after the primary database has been registered.
B. Backups of the standby control file taken while connected to the catalog where the database is registered, may be used to restore the control file on the primary database.
C. The standby database can not be registered in an RMAN catalog if the primary database has not been registered.
D. The standby database must be registered in an RMAN catalog before the primary database has been registered.

Answer: A,B

Explanation:
In a Data Guard environment, offloading backups to a physical standby database has certain requirements:
A: Once the primary database is registered in an RMAN catalog, the standby database can also be registered. This allows RMAN to manage backups coherently across both databases and leverage the standby database for backup purposes without interfering with the primary database's workload.
C: Backups of the standby control file taken while connected to the catalog where the database is registered can be used to restore the control file on the primary database. This ensures that backup metadata is consistent across the Data Guard configuration.
Options B and D are incorrect because there is no strict requirement for the order in which the primary and standby databases must be registered in an RMAN catalog. However, it is a common practice to register the primary database first.

NEW QUESTION # 42
Which three statements are true....... With no Oracle Streams or Goldengate configured?

A. Only standby databases can write redo....
B. They are required only for synchronous redo transport
C. They are required on a physical standby for real-time apply.
D. The LGWR process writes to them on ....
E. It is recommended to have them on the...
F. They are required on a logical standby for real-time apply

Answer: C,D,F

Explanation:
C . The LGWR (Log Writer) process is responsible for writing redo entries from the redo log buffer to the online redo log files on the primary database. This is a fundamental process in the Oracle Database architecture, ensuring that all changes made to the database are captured for purposes such as recovery, replication, and high availability.
D . Real-time apply on a logical standby database requires standby redo log files. The standby redo log files are used to store redo data received from the primary database before it is applied to the logical standby database. This enables the logical standby to apply changes as they are received, without waiting for the current redo log file to be archived.
E . Similarly, on a physical standby database, standby redo log files are used for real-time apply. They store redo data from the primary database, allowing the physical standby to apply redo data concurrently as it is received, rather than waiting for redo log files to be archived. This capability is crucial for maintaining a physical standby database that is closely synchronized with the primary database with minimal lag.
These functionalities are integral to Oracle Data Guard configurations and are not dependent on Oracle Streams or Oracle GoldenGate, which are separate technologies for data replication and integration.

NEW QUESTION # 43
Which TWO are TRUE about offloading backups to a physical standby database in a Data Guard environment?

A. The standby database must be registered in an RMAN catalog after the primary database has been registered.
B. Backups of the standby control file taken while connected to the catalog where the database is registered, may be used to restore the control file on the primary database.
C. The standby database can not be registered in an RMAN catalog if the primary database has not been registered.
D. The standby database must be registered in an RMAN catalog before the primary database has been registered.

Answer: A,B

Explanation:
In a Data Guard environment, offloading backups to a physical standby database has certain requirements:
* A: Once the primary database is registered in an RMAN catalog, the standby database can also be
* registered. This allows RMAN to manage backups coherently across both databases and leverage the standby database for backup purposes without interfering with the primary database's workload.
* C: Backups of the standby control file taken while connected to the catalog where the database is registered can be used to restore the control file on the primary database. This ensures that backup metadata is consistent across the Data Guard configuration.
Options B and D are incorrect because there is no strict requirement for the order in which the primary and standby databases must be registered in an RMAN catalog. However, it is a common practice to register the primary database first.
References: The Oracle Database Backup and Recovery User's Guide provides detailed procedures on how to manage RMAN backups in a Data Guard environment, including offloading backups to a standby database.

NEW QUESTION # 44

A. They work in Maximum Protection mode.
B. They do not work with Logical Standby databases.
C. They do not work with Snapshot Standby databases.
D. They work in Maximum Performance mode.
E. They work in Maximum Availability mode.

Answer: B,D
