Oracle Database 19c: Data Guard Administration Sample Questions (Q83-Q88):

NEW QUESTION # 83
You must configure on Oracle Data .......
1. A primary database
2. Three Physical Standby Databases
Examine these requirements:
A designated physical standby database should become the primary database automatically whenever the primary database fails.
2. The chosen protection mode should provide the highest level of protection possible without violating the other requirement.
Which redo transport mode and protection mode would you configure to meet these requirements?

A. FASTSYNC and Maximum Protection
B. SYNC and Maximum Protection
C. ASYNC and Maximum Performance
D. FASTSYNC and Maximum Availability

Answer: D

Explanation:
To meet the requirements of automatic failover and the highest level of protection without data loss, the combination of FASTSYNC redo transport mode and Maximum Availability protection mode is appropriate. FASTSYNC ensures that the performance impact on the primary database is minimized while still providing synchronous transport. Maximum Availability protection mode offers the highest level of data protection without compromising the availability of the primary database. In case of a network failure or a standby failure, the primary will not halt, avoiding disruption to the primary database operations.
Reference
Oracle Data Guard Concepts and Administration guide, which details the different protection modes and their respective levels of data protection and impact on database operations.

NEW QUESTION # 84
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 protection mode will automatically change to Maximum Performance.
C. Synchronous redo transport mode connections to the standby database are terminated.
D. The physical standby database instance is shut down by the Data Guard broker.

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.

NEW QUESTION # 85
Examine the procedure that you plan to execute on your logical standby:
SQL> EXECUTE DBMS_LOGSTDBY.SKIP(stmt => 'DML', schema_name => 'HR', object_name => 'EMPLOYEE'); What is a prerequisite for execution of this procedure?

A. Execute the DBMS_LOGSTDBY.APPLY_SET procedure to record errors that might cause SQL Apply to stop.
B. Stop SQL Apply on the logical standby database.
C. Change the redo transport mode if necessary to ASYNC.
D. Stop redo transport to the logical standby database.

Answer: B

NEW QUESTION # 86
A customer asks for your recommendation regarding this requirement:
1. We plan to have a Data Guard Configuration with one primary database and one physical standby database.
2. We want zero data loss in case of a disaster involving the loss of one component.
3. We want to do Real Application Testing occasionally on the Standby Database.
Which solution, if any, satisfies these requirements?

A. A far sync instance plus a snapshot standby database and real time apply that can be converted regularly into logical standby database to do real application testing
B. A physical standby database with synchronous redo transport that can be converted regularly into a snapshot standby to do real application testing
C. These requirements cannot be met.
D. A snapshot standby database with real time query that can be converted regularly into a physical standby database open read write, to do real application testing

Answer: B

Explanation:
Synchronous redo transport for zero data loss (B): To guarantee zero data loss in the case of a disaster, synchronous redo transport must be configured between the primary and standby databases.
Conversion to snapshot standby for testing (B): A physical standby database can be temporarily converted into a snapshot standby database to perform real application testing. After testing is completed, the snapshot standby can be converted back to a physical standby to resume its disaster recovery role.

NEW QUESTION # 87
You are planning to perform block comparison using the dbms comp package:

Which TWO statements are true?

A. The databases should be at least mounted before block comparison.
B. Logical standby databases can be the target database for the dbms_dbcomp.dbcomp procedure.
C. It can be used to detect lost writes and inconsistencies between the primary database and the cascaded standbys.
D. You can monitor the progress of an ongoing block comparison operation by querying VS SES SION_LONGOPS.
E. It requires that the DB_LOST_WKITE_protect initialization parameter be enabled.

Answer: A,D

Explanation:
The DBMS_COMPARISON package, used for comparing and converging data objects within a single database or between databases, requires that the databases involved in the block comparison be at least mounted (A). This allows the procedure to access the data blocks for comparison. Additionally, the progress of long-running operations such as block comparison can be monitored using the dynamic performance view V$SESSION_LONGOPS (D), which provides information on the operation's progress and estimated completion time.
Reference:
Oracle Database PL/SQL Packages and Types Reference provides comprehensive details on the DBMS_COMPARISON package, including its procedures and how to monitor their progress. Additionally, Oracle Database Reference explains the V$SESSION_LONGOPS view, which is commonly used for monitoring long operations in the database.
