Oracle Database 19c: Data Guard Administration Sample Questions (Q15-Q20):

NEW QUESTION # 15
Which three are prerequisites for enabling Fast-Start Failover?

A. Flashback Database must be enabled on the Fast-Start Failover target standby database.
B. Flashback Database must be enabled on the primary database.
C. A static service name must be configured only for the Fast-Start Failover target standby database.
D. The Fast-Start Failover target standby database must receive REDO synchronously when the configuration operates in Maximum Availability mode.
E. The Fast-Start Failover target standby database may receive REDO either synchronously or asynchronously when the configuration operates in Maximum Performance mode.

Answer: A,B,D

NEW QUESTION # 16
Examine this query and its output:

Which two statements are true?

A. Cats is a bystander database.
B. The master observer is not running, but should run on ol7.example.com.
C. The master observer is not connected to the database on which the query was executed.
D. The master observer is connected to the database on which the query was executed.
E. The master observer is currently running on ol7.example.com.

Answer: A,C

Explanation:
D . The database role indicated by FS_FAILOVER_STATUS as BYSTANDER implies that the database is a standby database in the Data Guard configuration. This means the database is neither a primary database nor an active failover target.
E . Since the FS_FAILOVER_OBSERVER_HOST column shows cats, it suggests that this is the host on which the observer would run. However, because the FS_FAILOVER_OBSERVER_PRESENT column is not shown, we cannot definitively state if the observer is currently connected or not. If FS_FAILOVER_OBSERVER_PRESENT is 'YES', the observer is connected, if 'NO', then it's not. In the absence of this column's output, the best assumption based on the available data is that the observer is not connected.
The output shows that the FS_FAILOVER_STATUS is BYSTANDER, which indicates that the database in question is not actively involved in a fast-start failover configuration as a primary or standby. It is in a bystander role, meaning that while it is part of a Data Guard configuration, it is neither a target for failover nor actively participating in failover operations. Additionally, FS_FAILOVER_OBSERVER_HOST shows 'cats', which indicates the host where the observer process is expected to run. However, since there is no information about the observer being present, we can infer that although 'cats' is designated for the observer to run, the observer is not currently connected to this database.
Reference
Oracle documentation on Data Guard configurations and the V$DATABASE view which provides information about the fast-start failover status and observer host.

NEW QUESTION # 17
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. The database must be in ARCHTVELOG mode.
C. The Data Guard real-time apply feature must be enabled.
D. A fast recovery area must be configured.
E. A far sync instance must be configured to flash back a standby when the primary has been flashed back.

Answer: B,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 # 18
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. 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.
B. Performing a role change with DGMGRL automatically notifies GDS which in turn activates the appropriate services.
C. DGMGRL may be used to add the Sales configuration to the Prod pool in gds.
D. Adding a database to the Sales configuration with DGMGRL automatically adds the database to the Prod Pool.
E. DGMGRL may be used to add a single database to the Sales configuration even if Sales is a member of the Prod pool.

Answer: B,C,E

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:

NEW QUESTION # 19
Which THREE statements are true about snapshot standby databases?

A. FLASHBACK DATABASE is enabled automatically on a physical standby database as part of the conversion into a snapshot standby database, if not already enabled.
B. FLASHBACK DATABASE must be manually enabled on a physical standby database before converting it into a snapshot standby database.
C. A snapshot standby database may be opened read-write.
D. A snapshot standby database can have Real-Time apply enabled.
E. FLASHBACK DATABASE is enabled automatically on a snapshot standby database after converting it from a physical standby database if not already enabled.
F. A snapshot standby database may be opened read-only.

Answer: A,C,E

Explanation:
Snapshot standby databases are a feature of Oracle Data Guard that allows a physical standby database to be temporarily converted into a read-write database for testing or other purposes. The true statements about snapshot standby databases are:
FLASHBACK DATABASE is enabled automatically on a snapshot standby database after converting it from a physical standby database if not already enabled (B): When a physical standby is converted to a snapshot standby, FLASHBACK DATABASE is automatically enabled to allow the database to be easily reverted back to its original state.
FLASHBACK DATABASE is enabled automatically on a physical standby database as part of the conversion into a snapshot standby database, if not already enabled (C): As part of the conversion process, FLASHBACK DATABASE is turned on to ensure that changes made while the database is in snapshot standby mode can be undone.
A snapshot standby database may be opened read-write (E): Once a physical standby is converted to a snapshot standby, it can be opened for read-write operations, allowing for testing and other tasks that require a writable database.
