Oracle Database 19c: Data Guard Administration Sample Questions (Q90-Q95):

NEW QUESTION # 90
Examine the fast-start failover configuration:

A. The observer will initiate a failover when the primary database is unable to produce local archived redo log files.
B. A failover may occur if the observer has lost connectivity to the primary database, even if the Fast-Start Failover target standby database has a good connection to the primary database
C. If South_Sales develops a problem and cannot be the target of a failover, the broker automatically changes the fast-start failover target to one of the other candidate targets.
D. The observer is running.
E. You must disable fast-start failover first to change the fast-start failover target to East sales.

Answer: A,B,D

NEW QUESTION # 91
Which two are prerequisites for configuring Transaction Guard in a Data Guard environment?

A. Create a database service with COMMIT_OUTCOME set to TRUE, and ensure clients use that service to connect to the database instance.
B. Grant execute permission on the DBMS_APP_CONT package to relevant database schema owners.
C. Ensure that connection descriptors for database clients use the failover clause with the COMMIT_OUTCOME parameter set to TRUE.
D. Set INSTANCE_NAME identically on all the Data Guard Configuration databases and modify the local service name on the client to include a CONNECTION_LIST containing all the standby hosts.
E. Create a database service with COMMIT_OUTCOME set to TRUE and ensure that the service is statically registered with the default listener on the primary host.

Answer: A,B

NEW QUESTION # 92
Examine the Data Guard configuration:

Which three will be true after a successful failover to Cats?

A. The configuration will be in Maximum Performance mode.
B. Sheep will be in the enabled state.
C. Sheep will be in the disabled state.
D. Dogs will be in the disabled state and has to be manually reinstated.
E. The configuration will be in Maximum Availability mode.

Answer: B,D,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.
References: The behavior of Oracle Data Guard during failover and the resulting configuration state is described in the Oracle Data Guard Broker documentation.

NEW QUESTION # 93
You created the PRODSBY1 physical standby database for the PROD primary database using gql and RMAN. You are planning to create a Data Guard Broker configuration. You execute the command:

Which three statements are true regarding the execution of the command?

A. The PRODSBYI standby database is automatically added to the configuration if Oracle Net connectivity to the PRODSBYl database instance is defined on the primary host.
B. The Data Guard Broker configuration files is automatically created in the destinations specified by the DG_BROKER_CONFIG_FILEn initialization parameters on the primary database.
C. The command will execute successfully only if Oracle Net connectivity to the PROD and PRODSBYl database instances are defined on the primary host.
D. The command will execute successfully only if Oracle Net connectivity to the PROD database instance is defined on the primary host.
E. The PRODSBY1 standby database is automatically added to the configuration if DG_BROKER_START is TRUE for PRODSBYl.
F. The command will execute successfully only if the DG_BROKER_START initialization parameter is set to TRUE for the PROD database instance.

Answer: B,D,F

Explanation:
The command executed (CREATE CONFIGURATION 'DGConfig' AS PRIMARY DATABASE IS 'PROD' CONNECT IDENTIFIER IS PROD;) is used to create a Data Guard Broker configuration named 'DGConfig'. The successful execution of this command depends on several conditions:
A: The DG_BROKER_START parameter must be set to TRUE on the primary database to start the Data Guard Broker processes. Without the broker processes running, the configuration cannot be created.
D: Oracle Net connectivity to the PROD database instance must be established on the primary host. This is because the Data Guard Broker requires network accessibility to communicate with the primary database and manage the configuration.
E: When the configuration is created, the Data Guard Broker configuration files are indeed automatically created in the locations specified by the DG_BROKER_CONFIG_FILEn parameters on the primary database.
It's important to note that the command will not automatically add the PRODSBY1 standby database to the configuration (thus B and C are not correct), and there is no requirement for the standby database to have Oracle Net connectivity defined on the primary host for the execution of this command (making F incorrect as well).

NEW QUESTION # 94
Examine the Data Guard configuration after an accidental switchover to Sheep:
DGMGRL> show configuration;
Configuration - Animals
Protection Mode: MaxAvailability
Databases:
sheep - Primary database
dogs - Logical standby database
cats - Physical standby database (disabled)
ORA-16795: the standby database needs to be re-created
Fast-Start Failover: DISABLED
Configuration Status:
SUCCESS
Which three statements will be true after a switchover to Dogs?

A. Dogs will be the primary database.
B. Sheep will be an enabled logical standby database.
C. Cats will be an enabled physical standby database.
D. Cats will be a disabled physical standby database that can be manually enabled.
E. Sheep will be a disabled logical standby database.

Answer: A,B,D
