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

NEW QUESTION # 40
You are using Data Guard in conjunction with Global Database Services.
You have a Data Guard Broker configuration called Sales and a GDS pool called Prod.
Which three are true concerning the management of the broker configuration when using GDS?

A. Performing a role change with DGMGRL automatically notifies GDS which in turn activates the appropriate services.
B. Adding a database to the Sales configuration with DGMGRL requires that the Sales configuration be disabled first. It must then be enabled after the new database is added to the configuration.
C. DGMGRL may be used to add the Sales configuration to the Prod pool in gds.
D. DGMGRL may be used to add a single database to the Sales configuration even if Sales is a member of the Prod pool.
E. Adding a database to the Sales configuration with DGMGRL automatically adds the database to the Prod Pool.

Answer: A,C,D

Explanation:
In the context of Oracle Data Guard and Global Database Services (GDS):
* DGMGRL may be used to add the Sales configuration to the Prod pool in gds (A): Data Guard Broker's command-line interface DGMGRL can be utilized to manage configurations with GDS, allowing the addition of Data Guard Broker configurations to GDS pools.
* Performing a role change with DGMGRL automatically notifies GDS which in turn activates the appropriate services (B): When a role change is executed using DGMGRL, GDS is automatically notified, and it then activates the services that are appropriate for the new database roles.
* DGMGRL may be used to add a single database to the Sales configuration even if Sales is a member of the Prod pool (C): DGMGRL provides the capability to manage individual databases within a broker configuration, including adding databases to a configuration that is already part of a GDS pool.References:
* Oracle Data Guard Broker documentation
* Oracle Global Data Services documentation

NEW QUESTION # 41
In Oracle Database 19c, you can set the value of database initialization parameters in a database using the EDIT DATABASE... SET PARAMETER Command:
DGMGRL> EDIT DATABASE 'boston' SET PARAMETER log_archive_trace - 1;
Which THREE statements are TRUE about the command?

A. The edit database parameter command can only be used to modify the value of a dynamic parameter in a database.
B. The value set using this command is directly applied to the boston database.
C. The value set using this command is directly stored in the broker configuration file.
D. The database must be available when the above command is run.
E. The EDIT DATABASE PARAMETER command can be used to set the value of a static parameter in a database.

Answer: A,B,D

Explanation:
The EDIT DATABASE...SET PARAMETER command in Data Guard Management (DGMGRL) is used to modify the value of initialization parameters for a database within a Data Guard configuration. This command can be used to modify both static and dynamic parameters, but if a static parameter is changed, the new value will take effect only after the database is restarted. The database must be up and running for the command to execute, and the values set using the command are directly applied to the specified database (in this case, 'boston') .

NEW QUESTION # 42
Examine the Data Guard configuration:

What happens if you issue "switchover to sheep;" at the DGMGRL prompt?

A. The switchover succeeds and Dogs becomes the new failover target.
B. The switchover succeeds but Dogs needs to be reinstated.
C. The switchover succeeds and Fast-Start Failover is suspended.
D. It results in an error indicating that a switchover is not allowed.
E. The switchover succeeds and Cats becomes the new failover target.

Answer: A

Explanation:
When issuing a "switchover to sheep;" command in a Data Guard configuration, the primary database (Dogs) transitions to a standby role, and the target standby database (Sheep) becomes the new primary database. Fast-Start Failover (FSFO) remains enabled, but its target changes according to the new roles of the databases. Since Cats is also a physical standby database, it does not become the failover target by default unless it is specified in the broker configuration. After the switchover, the original primary (Dogs) becomes the new standby database and thus the new failover target for FSFO.
Reference:
Oracle Data Guard Broker documentation provides detailed procedures and explanations of switchover operations, including how FSFO targets are affected post-switchover. This behavior is consistent across different Oracle Database versions that support Data Guard and FSFO.

NEW QUESTION # 43
Which two are true about the use of RMAN recovery catalogs when offloading backups to a physical standby database?

A. The physical standby database may be used to register the database in the recovery catalog, if the primary is not registered.
B. It backups that are offloaded to a physical standby database are taken when not connected to a recovery catalog, then they may still be used for restoration on the primary database.
C. Primary and physical standby databases may use different virtual recovery catalogs in the same physical recovery catalog.
D. The primary and physical standby databases must be registered separately in the recovery catalog, if a far sync instance is used to route redo to the physical standby database.
E. It is not necessary to use a recovery catalog unless a far sync instance is used to route redo to the physical standby database.

Answer: B,C

NEW QUESTION # 44
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. If the former primary database became a logical standby database it will be in mount state.
D. The former primary database will always be open.
E. The new primary database will be open read-write.
F. If the former primary database became a logical standby database it will be open read-write.

Answer: B,E,F

Explanation:
After a successful switchover operation in a Data Guard environment, the new primary database (the former standby) will be open read-write (option A). If the former primary database transitions to a logical standby database, it will also be open read-write (option C), allowing it to apply redo data while servicing read-only queries. The former primary, if converted to a physical standby, will adopt the state that the former physical standby database was in prior to the switchover, which can vary based on the configuration prior to the switchover (option D). The state of a physical standby database can range from mounted to open read-only, depending on whether Real-Time Query was enabled. Thus, the exact state will depend on the pre-switchover setup. It's also essential to highlight that options B and E suggest specific states for a former primary turned logical standby, and a former primary turned physical standby, respectively, but these states are not fixed and depend on the configurations set up by the database administrators. References: The answers are corroborated by Oracle's documentation on Data Guard switchovers, specifically in the Oracle Data Guard Concepts and Administration guide, which explains the roles and states of databases in a Data Guard configuration before and after switchovers.
