Oracle Database 19c: Data Guard Administration Sample Questions (Q79-Q84):

NEW QUESTION # 79
Which three are prerequisites for enabling Fast-Start Failover?

  • A. Flashback Database must be enabled on both the primary database and the Fast-Start Failover target standby database.
  • B. You can specify only one standby database as the fast-start failover target.
  • C. The Data Guard environment must be managed by the Data Guard Broker.
  • D. The maximum protection mode can be used, but with two or more standby databases.
  • E. The configuration must be operating in either Maximum Performance or Maximum Protection mode.
  • F. Flashback Database must be enabled only on the Fast-Start Failover target standby database.

Answer: A,B,C

Explanation:
To enable Fast-Start Failover in a Data Guard environment, the following conditions must be in place:
The Data Guard environment must be managed by the Data Guard Broker (A): The Broker simplifies management tasks and is required to enable fast-start failover, which is an automatic failover mechanism provided by Data Guard.
You can specify only one standby database as the fast-start failover target (C): Fast-start failover is designed to fail over to a single, predetermined standby database, known as the target standby.
Flashback Database must be enabled on both the primary database and the Fast-Start Failover target standby database (F): Flashback Database provides a quick way to revert a database to a point in time before a logical or physical corruption or error occurred. It must be enabled on both the primary and target standby databases to allow for the possibility of reinstating the old primary as a standby after a failover.

NEW QUESTION # 80
Which four statements are true regarding SQL Apply filters for a logical standby database?

  • A. They can be used to skip ALTER TABLE commands on specific tables.
  • B. They can be used to skip execution of DML triggers on a table while allowing the DML to execute.
  • C. They can be used to skip CREATE TABLE commands.
  • D. They can be used to stop SQL apply if it encounters an error.
  • E. They can be used to skip all SQL statements executed on a specific pluggable database (PDB) within a standby multitenant container database (CDB).
  • F. They can be used to skip ALTE1 STEM and ALTER DATABASE commands.
  • G. They can only be used to skip DML statements on a table.

Answer: A,B,C,F

Explanation:
Based on the Oracle Database 19c documentation, the correct answers about SQL Apply filters for a logical standby database are:
A). They can be used to skip execution of DML triggers on a table while allowing the DML to execute.
B). They can be used to skip CREATE TABLE commands.
C). They can be used to skip ALTER SYSTEM and ALTER DATABASE commands.
G). They can be used to skip ALTER TABLE commands on specific tables.
Comprehensive Detailed Explanation:
SQL Apply filters in a logical standby database can be set to control which SQL operations are applied to the standby. These filters allow for certain commands to be skipped, ensuring that they do not impact the standby database. For example, filters can be used to skip the execution of DML triggers to prevent them from firing during SQL Apply, while still allowing the underlying DML to be executed on the logical standby database. This is particularly useful when certain triggers are not desired to run in a standby environment. CREATE TABLE, ALTER SYSTEM, ALTER DATABASE, and specific ALTER TABLE commands can also be skipped using SQL Apply filters to prevent unwanted structural changes or administrative operations from affecting the logical standby database. These capabilities provide a level of control to ensure that the logical standby database reflects only the desired state of the primary database.
Reference:
Oracle Database SQL Language Reference and Oracle Data Guard Concepts and Administration guide offer comprehensive details on the use of SQL Apply filters, including the range of SQL statements that can be influenced by these filters in a logical standby database environment.


NEW QUESTION # 81
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 value set using this command is directly stored in the broker configuration file.
  • B. The value set using this command is directly applied to the boston database.
  • C. The edit database parameter command can only be used to modify the value of a dynamic parameter in a database.
  • D. The EDIT DATABASE PARAMETER command can be used to set the value of a static parameter in a database.
  • E. The database must be available when the above command is run.

Answer: B,C,E

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 # 82
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 Availability
  • B. FASTSYNC and Maximum Protection
  • C. ASYNC and Maximum Performance
  • D. SYNC and Maximum Protection

Answer: A

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 # 83
You have a Data Guard broker configuration consisting of:
A primary database
One local physical standby database
One far sync instance
A remote physical standby database
The broker configuration was created with the DGMGRL utility after creating all the databases and the far sync instance with command-line tools.
What is the correct way to add this configuration to Enterprise Manager Cloud Control assuming all the nodes have been discovered already as Enterprise Manager targets?

  • A. Discover the primary database as a target in Enterprise Manager Cloud Control. Then discover the existing Data Guard Broker configuration for the primary and all the other databases in the configuration will be discovered as targets and be ready to be monitored.
  • B. Use the DGMGRL utility to register the configuration with the Enterprise Manager Cloud Control agent on the primary database node. This will enable the discovery of all the other databases in the configuration as targets which will be ready to be monitored.
  • C. Discover either of the physical standby databases as a target by refreshing the node on which they run, and the other databases and instances in the Data Guard Broker configuration will be discovered as targets automatically and be ready to be monitored.
  • D. Discover the primary as a target by refreshing the node on which it runs, and the other databases and instances in the Data Guard broker configuration will be discovered as targets automatically and be ready to be monitored.
  • E. Delete the Data Guard Broker configuration using DGMGRL and then re-create it using Enterprise Manager Cloud Control to enable all the databases in the configuration to be discovered as targets and to be ready to be monitored.

Answer: A
