Oracle Database 19c: Data Guard Administration Sample Questions (Q34-Q39):

NEW QUESTION # 34
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. Sheep will be in the disabled state.
E. The configuration will be in Maximum Availability mode.

Answer: A,B,E

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 # 35
Examine the Data Guard configuration:
DGMGRL> show configuration;
Configuration - Animals
Protection Mode: MaxAvailability
Databases:
dogs - Primary database
sheep - Snapshot standby database
cats - Physical standby database
Fast-Start Failover: DISABLED
Configuration Status:
SUCCESS
You receive an error while attempting to raise the protection mode to Maximum Protection:
DGMGRL> edit configuration set protection mode as maxprotection;
Error: ORA-16627: operation disallowed since no standby databases would remain to support protection mode Failed.
Which is the minimum statement, or sequence of statements you must execute to enable successful raising of the protection mode to Maximum Protection?

A. DGMGRL> edit database dogs set property LogxptMode=sync;
B. DGMGRL> edit database dogs set property LogXptMode=sync;
DGMGRL> edit database cats set property LogXptMode=sync;
C. DGMGRL> edit database dogs set property LogXptMode=sync;
DGMGRL> edit database sheep set property LogxptMode=sync;
DGMGRL> edit database cats set property LogXptMode=sync;
D. DGMGRL> edit database cats set property LogXptMode=sync;
E. DGMGRL> edit database sheep set property LogXptMode=sync;
F. DGMGRL> edit database dogs set property LogxptMode=sync;
DGMGRL> edit database sheep set property LogxptMode=sync;

Answer: B

NEW QUESTION # 36
Which THREE are always benefits of using a logical standby database?

A. It can be used for reporting workloads requiring additional indexes or materialized views or both.
B. It can be used for testing patchsets without affecting the primary database.
C. It can be used for database rolling release upgrades.
D. It provides a disaster-recovery solution with switchover and failover options that can recover any data updated on the primary database.
E. It can be used to replicate a single pluggable database (PDB) in a multitenant container database.
F. It can be used as an updatable database for Real Application Testing and then converted back to a standby database without affecting the updates.

Answer: A,C,D

Explanation:
Logical standby databases are a key feature of Oracle Data Guard and offer several distinct advantages, especially in terms of flexibility for reporting, upgrades, and disaster recovery:
* Disaster-recovery solution with switchover and failover options (A): Logical standby databases provide a robust disaster-recovery solution, ensuring that any data updated on the primary database can be recovered. They support both switchover and failover operations, allowing for smooth role transitions between the primary and standby databases.
* Used for reporting workloads requiring additional indexes or materialized views (B): Logical standby databases can be opened for read-write operations and can have additional indexes or materialized views that are not present in the primary database. This makes them ideal for offloading reporting and querying workloads from the primary database.
* Database rolling release upgrades (D): Logical standby databases can be used to perform rolling upgrades of the Oracle Database software. This allows the database to be upgraded with minimal downtime, as the standby database is upgraded first, followed by a switchover to make it the new

NEW QUESTION # 37
Which TWO observations are true about the Far Sync instance?

A. Applies redo received
B. Can be created using the RMAN DUPLICATE command
C. Can only be created using a series of SQL commands
D. Receives redo synchronously from the primary database
E. Includes a standby control file, password file, data files, standby redo logs, and archive logs

Answer: A,D

Explanation:
A Far Sync instance is a special kind of Oracle Data Guard configuration that allows synchronous redo transport from a primary database to a remote standby database with minimum impact on the primary database's performance. The Far Sync instance receives redo data synchronously from the primary database (A), then ships it asynchronously to the remote standby database, thus extending zero data loss protection over longer distances and higher network latency environments than would be practical with a synchronous standby alone. The Far Sync instance does not apply the redo data; it just receives and ships it (E). A Far Sync instance does not have data files, and it cannot apply redo to stay synchronized with the primary database.
Reference:
Oracle Database High Availability Overview and Oracle Data Guard Concepts and Administration documentation detail the role and configuration of Far Sync instances, including how they contribute to achieving zero data loss disaster recovery over long distances.

NEW QUESTION # 38
Your Data Guard configuration consists of these components and settings:
1. A primary database
2. A remote physical standby database
3. Real-time query is enabled
4. Redo transport mode is synchronous
5. Protection mode is maximum availability
6. The Data Guard broker is used
You notice that the standby destination fails to acknowledge reception of redo within net_timeout period of time.
Which is true in this scenario?

A. Real-time query will be disabled on the physical standby.
B. The physical standby database instance is shut down by the Data Guard broker.
C. Synchronous redo transport mode connections to the standby database are terminated.
D. The protection mode will automatically change to Maximum Performance.

Answer: C

Explanation:
In a Data Guard configuration where the protection mode is set to Maximum Availability and synchronous redo transport is enabled, if the standby destination fails to acknowledge the reception of redo within the net_timeout period, the primary database will terminate the synchronous redo transport mode connections to the standby database to protect the primary database from hanging (C). The primary database then operates in a Maximum Performance mode until the issue is resolved. This behavior ensures that the primary database can continue to process transactions even when the standby database is temporarily unavailable.
References:The Oracle Data Guard Broker documentation and Oracle Data Guard Concepts and Administration guide detail the behavior of different protection modes and the response to network timeouts, including the fallback to asynchronous redo transport to maintain primary database availability.
