Oracle Database 19c: Data Guard Administration Sample Questions (Q25-Q30):

NEW QUESTION # 25
Which THREE steps are prerequisites for the creation of a physical standby database on a separate server using the RMAN active database duplication method?

A. Set the DB_UNIQUE_NAME parameter on the primary database to a different value than that of the DB_NAME name parameter.
B. Put the primary database into archivelog mode.
C. startup nomount the standby database instance.
D. Configure Oracle Net connectivity on the primary host to the standby database instance.
E. Establish user equivalence for the database software owner between the primary host and standby host.

Answer: C,D,E

Explanation:
Creating a physical standby database using RMAN active database duplication requires certain prerequisites to ensure a successful and seamless operation:
* Configure Oracle Net connectivity on the primary host to the standby database instance (A):
* Proper Oracle Net connectivity between the primary and standby servers is essential for communication and data transfer during the duplication process. Oracle Net services provide the network foundation for Oracle Database, Oracle Net Listener, and Oracle applications.
* Establish user equivalence for the database software owner between the primary host and standby host (B): User equivalence ensures that the user who owns the Oracle Database software on the primary server has the same privileges on the standby server. This is crucial for RMAN to perform operations on both servers without encountering permission issues.
* Startup nomount the standby database instance (C): The standby database instance needs to be started in the NOMOUNT stage before the duplication can begin. This prepares the environment for creating the control file and restoring the database without mounting it, which is a necessary step in the RMAN duplication process.References:

NEW QUESTION # 26
Your Data Guard environment has two remote physical standby databases.
Client applications use the local naming method to define connectivity to the primary database instance.
Which will automatically redirect clients to the new primary database in case of a switchover or failover?

A. Set the LOCAL_LISTENER parameter for all the database instances, to register services with the default listener on the primary database host.
B. Set the DB_NAME parameter identically on all databases; modify the connection descriptor on the clients to use DB_NAME to connect to the primary database instance.
C. Configure a PRIMARY role service on the Primary and Standby and modify the Client connect descriptor to include both the Primary and the Standby.
D. Create a database service on the standby databases; automate the start of the service after a role change, and modify the connection descriptor on the clients to use that service.

Answer: D

NEW QUESTION # 27
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 physical standby database with synchronous redo transport that can be converted regularly into a snapshot standby to do real application testing
B. 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
C. These requirements cannot be met.
D. 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

Answer: A

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 # 28
Which two factors can cause an increase in redo transport lag?

A. The size of the online redo log files on the primary database.
B. Increase in network latency between the primary database and a redo transport destination.
C. The size of the online redo log files on the standby database.
D. The size of the standby redo log files on the primary database.
E. Increase in redo generation rate on the primary database.

Answer: B,E

NEW QUESTION # 29
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. The configuration must be operating in either Maximum Performance or Maximum Protection mode.
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. You can specify only one standby database as the fast-start failover target.
F. Flashback Database must be enabled only on the Fast-Start Failover target standby database.

Answer: A,C,E

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.
