Oracle Database 19c: Data Guard Administration Sample Questions (Q10-Q15):

NEW QUESTION # 10
Which three actions are performed by the START PLAN procedure of the DBMS ROLLING package?

A. creating a guaranteed restore point on the standby databases
B. creating a guaranteed restore point on the primary database
C. converting the designated physical standby database into a logical standby database
D. switching the primary database to the logical standby role
E. starting media recovery on all the Leading Group Standby databases
F. building a LogMiner dictionary on the primary database instance

Answer: A,B,F

Explanation:
The DBMS_ROLLING package facilitates a rolling upgrade process across a Data Guard configuration. The START PLAN procedure in particular handles several critical actions, including:
Creating a guaranteed restore point on the standby databases (B): This ensures that the standby databases can be reverted to their state before the rolling upgrade process in case of any issues.
Building a LogMiner dictionary on the primary database instance (C): This is necessary for logical standby databases to interpret redo data during the SQL Apply process.
Creating a guaranteed restore point on the primary database (D): Similar to the standby databases, this ensures that the primary database can be reverted to a known good state if necessary.

NEW QUESTION # 11
On your logical standby database, you specified these rules:

After completion of the weekend batch cycle you attempt to delete the SQL Apply filters:

Which is TRUE regarding the execution of the UNSKIP procedure?

A. It deletes both the SQL Apply filters.
B. It returns an error because the syntax to delete a SQL Apply filter must specify the same object names as specified when the filter was added.
C. It succeeds only if all DML statements executed on the primary have been applied on the logical standby deleting the SQL Apply filter.
D. It succeeds but the SQL Apply filters are not deleted.
E. It succeeds only if SQL apply is stopped before deleting the SQL Apply filter.

Answer: A

Explanation:
The execution of the UNSKIP procedure is designed to remove SQL Apply filters that have been previously set up on a logical standby database. Based on the provided statements, the UNSKIP procedure is directed to delete any SQL Apply filters for DML statements associated with objects in the 'HR' schema that start with 'EMP'. Since both SKIP procedures had the same schema name ('HR') and statement type ('DML'), and the UNSKIP procedure uses a wildcard (%) for the object name, it will successfully remove both of the SQL Apply filters for 'EMP_NEW' and 'EMP_OLD', as both object names match the pattern provided in the UNSKIP procedure.
Reference:
Oracle's Data Guard documentation and SQL Language Reference provide insights into managing SQL Apply filters on a logical standby database using the DBMS_LOGSTDBY package. This includes adding and removing filters through SKIP and UNSKIP procedures.

NEW QUESTION # 12
Which three Data Guard monitoring activities may be performed using Enterprise Manager Cloud Control?

A. You can check the potential data loss in the event of a disaster.
B. You can monitor the redo apply rate on a snapshot standby database.
C. You can set a critical threshold on the redo generation rate metric for a primary database.
D. You can set a warning threshold on the redo generation rate metric for a physical standby database.
E. You can check if redo apply needs to be tuned.
F. You can monitor the redo apply rate on a logical standby database.

Answer: A,C,F

Explanation:
Enterprise Manager Cloud Control offers comprehensive monitoring capabilities for Oracle Data Guard environments. It enables monitoring the rate at which redo is being applied on a logical standby database (A), which is crucial for ensuring that the standby database is keeping up with the changes from the primary. It also allows setting thresholds on performance metrics, such as the redo generation rate on the primary database (B), to alert administrators when values exceed critical or warning thresholds. Additionally, it provides the capability to estimate the potential data loss in the event of a disaster (E), helping in disaster recovery planning and ensuring business continuity.
References:Oracle Enterprise Manager Cloud Control documentation provides extensive information on its monitoring features for Oracle Data Guard, including setting thresholds, estimating potential data loss, and tracking redo apply rates.

NEW QUESTION # 13
Which four factors can influence the rate of SQL apply on a logical standby database?

A. the number of PREPAER processes
B. the size of the shared pool
C. the number of coordinator processes on the standby database instance
D. the size of the undo tablespace on the logical standby database
E. the number of full table scans performed by SQL apply
F. the number of applier processes

Answer: A,C,E,F

Explanation:
The rate of SQL apply on a logical standby database can be influenced by:
A: The number of PREPARER processes (which seems to be a typographical error and should read as PREPARER or similar) which prepare the redo data for the applier processes.
B: The number of coordinator processes on the standby database instance which coordinate the SQL apply activities.
C: The number of full table scans performed by SQL apply since full table scans can be resource-intensive and slow down the apply rate.
E: The number of applier processes which apply the redo data to the logical standby database.
Option D is incorrect as the size of the undo tablespace on the logical standby database is more likely to affect the SQL apply lag rather than the rate of SQL apply.
Option F is incorrect because the size of the shared pool would typically not influence the rate of SQL apply. The shared pool is more related to the caching of shared SQL and PL/SQL code and control structures.

NEW QUESTION # 14
Which two statements are true regarding asynchronous redo transport in a Data Guard

A. This transport mode satisfies the minimum requirements for Maximum Availability data protection mode.
B. A transaction can commit without waiting for redo to be sent to any standby database in the data guard configuration.
C. Real-time query performance on a physical standby database improves for current read requests when using this transport mode.
D. This transport mode satisfies the minimum requirements for Maximum Performance data protection mode.
E. The performance of SQL apply on a logical standby database always improves when using this transport mode.

Answer: B,D

Explanation:
Asynchronous redo transport is a method where the primary database does not wait for an acknowledgment from the standby database before committing transactions, which helps in minimizing the impact on the primary database's performance (B). This transport mode is associated with the Maximum Performance data protection mode, which prioritizes performance over synchronicity of data between the primary and standby databases (C). While it provides a level of data protection, there could be some data loss in the event of a primary database failure because redo data may not have been transmitted to the standby database at the time of the failure.
References:Oracle Data Guard Concepts and Administration documentation provides detailed explanations of different redo transport modes and their implications on data protection and performance. Asynchronous transport mode's behavior and association with Maximum Performance mode are outlined explicitly.
