Oracle Database 19c: Data Guard Administration Sample Questions (Q87-Q92):

NEW QUESTION # 87
Examine the Data Guard configuration:

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

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

Answer: A,C,D

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 # 88
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 command will execute successfully only if Oracle Net connectivity to the PROD database instance is defined on the primary host.
B. The command will execute successfully only if Oracle Net connectivity to the PROD and PRODSBYl database instances are defined on the primary host.
C. The command will execute successfully only if the DG_BROKER_START initialization parameter is set to TRUE for the PROD database instance.
D. The PRODSBY1 standby database is automatically added to the configuration if DG_BROKER_START is TRUE for PRODSBYl.
E. 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.
F. 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.

Answer: A,C,E

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).
References: This information can be validated in Oracle's Data Guard Broker documentation, which outlines the requirements for setting up and managing a Data Guard configuration using the Data Guard Broker.

NEW QUESTION # 89
Which three are true about using RMAN in a Data Guard environment?

A. Backups of control files taken on a physical standby are not interchangeable with a primary.
B. Backups of archived redo logs taken on a physical standby are interchangeable with a primary.
C. A recovery catalog is required when RMAN is used to take backups from a logical standby database in a Data Guard configuration if you plan to recover the primary using those backups.
D. A recovery catalog is required when RMAN is used to take backups from a physical standby database if you plan to recover the primary using those backups.
E. Backups of data files taken on a physical standby are interchangeable with a primary.

Answer: A,B,E

NEW QUESTION # 90
You are using Data Guard in conjunction with Global Database Services.
You have a Data Guard Broker configuration called Sales and a GDS pool called Prod.
Which three are true concerning the management of the broker configuration when using GDS?

A. DGMGRL may be used to add a single database to the Sales configuration even if Sales is a member of the Prod pool.
B. DGMGRL may be used to add the Sales configuration to the Prod pool in gds.
C. Adding a database to the Sales configuration with DGMGRL requires that the Sales configuration be disabled first. It must then be enabled after the new database is added to the configuration.
D. Adding a database to the Sales configuration with DGMGRL automatically adds the database to the Prod Pool.
E. Performing a role change with DGMGRL automatically notifies GDS which in turn activates the appropriate services.

Answer: A,B,E

Explanation:
In the context of Oracle Data Guard and Global Database Services (GDS):
* DGMGRL may be used to add the Sales configuration to the Prod pool in gds (A): Data Guard Broker's command-line interface DGMGRL can be utilized to manage configurations with GDS, allowing the addition of Data Guard Broker configurations to GDS pools.
* Performing a role change with DGMGRL automatically notifies GDS which in turn activates the appropriate services (B): When a role change is executed using DGMGRL, GDS is automatically notified, and it then activates the services that are appropriate for the new database roles.
* DGMGRL may be used to add a single database to the Sales configuration even if Sales is a member of the Prod pool (C): DGMGRL provides the capability to manage individual databases within a broker configuration, including adding databases to a configuration that is already part of a GDS pool.References:
* Oracle Data Guard Broker documentation
* Oracle Global Data Services documentation

NEW QUESTION # 91
Which TWO are benefits of using Transaction Guard in a Data Guard environment?

A. It protects against logical corruptions being replicated to standby databases.
B. It provides application continuity by replaying transactions interrupted by a failover or a switchover
C. It protects against user errors being replicated to standby databases.
D. It provides application continuity by rolling back uncommitted transactions interrupted by a failover or switchover.
E. It protects against recoverable errors during a planned or an unplanned outage of a primary database.

Answer: D,E

Explanation:
Transaction Guard provides benefits in terms of transaction consistency and recovery in a Data Guard environment:
* It provides application continuity by rolling back uncommitted transactions interrupted by a failover or switchover (B): Transaction Guard ensures that any uncommitted transactions at the time of an outage are rolled back consistently, thus preserving the integrity of the application's data and state.
* It protects against recoverable errors during a planned or an unplanned outage of a primary database (D): Transaction Guard offers protection against errors that can occur during outages, allowing applications to resume operations more quickly and reliably after recovery.References:

* Oracle Real Application Clusters Administration and Deployment Guide
