Oracle Database 19c: Data Guard Administration Sample Questions (Q17-Q22):

NEW QUESTION # 17
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 Protection
B. FASTSYNC and Maximum Availability
C. SYNC and Maximum Protection
D. ASYNC and Maximum Performance

Answer: B

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 # 18
Which two are true about managing and monitoring Oracle container databases in a Data Guard environment using the broker?

A. After a role change, the broker opens all Pluggable databases (pdbb) on the new primary.
B. If the primary database is a container database, then a physical standby may be a non-container database.
C. If the primary database is a container database, then a logical standby may be a non-container database.
D. If the primary database is not a container database, then a standby may be a container database.
E. All broker actions execute at the root container for container databases.

Answer: A,E

Explanation:
In the context of Oracle Data Guard and container databases (CDBs) managed by Data Guard Broker:
* All broker actions execute at the root container for container databases (D): When using Data Guard Broker to manage a CDB, the actions performed by the broker are executed at the level of the root container. This is because the root container maintains the control and configuration information that applies to the entire CDB, including all of its pluggable databases (PDBs).
* After a role change, the broker opens all Pluggable databases (PDBs) on the new primary (E):
Following a role transition such as a switchover or a failover, Data Guard Broker ensures that all PDBs within the CDB of the new primary database are opened, which is essential to resume operations of the PDBs without manual intervention.References:

* Oracle Multitenant Administrator's Guide

NEW QUESTION # 19
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. These requirements cannot be met.
B. A physical standby database with synchronous redo transport that can be converted regularly into a snapshot standby to do real application testing
C. 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
D. 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

Answer: B

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 # 20
Your Data Guard configuration consists of these components and settings:
1. A primary database
2. A remote physical standby database
3. Real-time query is enabled
4. Redo transport mode is synchronous
5. Protection mode is maximum availability
6. The Data Guard broker is used
You notice that the standby destination fails to acknowledge reception of redo within net_timeout period of time.
Which is true in this scenario?

A. The protection mode will automatically change to Maximum Performance.
B. Synchronous redo transport mode connections to the standby database are terminated.
C. The physical standby database instance is shut down by the Data Guard broker.
D. Real-time query will be disabled on the physical standby.

Answer: B

Explanation:
In a Data Guard configuration where the protection mode is set to Maximum Availability and synchronous redo transport is enabled, if the standby destination fails to acknowledge the reception of redo within the net_timeout period, the primary database will terminate the synchronous redo transport mode connections to the standby database to protect the primary database from hanging (C). The primary database then operates in a Maximum Performance mode until the issue is resolved. This behavior ensures that the primary database can continue to process transactions even when the standby database is temporarily unavailable.
References:The Oracle Data Guard Broker documentation and Oracle Data Guard Concepts and Administration guide detail the behavior of different protection modes and the response to network timeouts, including the fallback to asynchronous redo transport to maintain primary database availability.

NEW QUESTION # 21
Suppose that you manage the following databases in your environment:
* boston: Primary database with a single PDB called DEVI
* london: Physical standby database protecting the PDB called DEVI
* orcl: Stand-alone database with a single PDB called PDB1 as a remote clone source You are planning to run the following command to create a remote clone in the primary database (boston) using pdbi in orcl:
Which are the THREE prerequisites for automating instantiation of the PDB in the standby database (london)?

A. Open PDBI (remote clone source) in Read Write.
B. Set standby_pdb_source_file_dblink to clone_link in the london database.
C. Enable Active Data Guard in the _ondon database.
D. Set STANDBY_PDB_SOURCE_FILE_DIRECTORY to <location of the PDB> in the london database.
E. Set STANDBY_FILE_MANAGEMENT to auto in the london database.
F. Open PDBI (remote clone source) in Read Only.

Answer: D,E,F

Explanation:
To automate the instantiation of a PDB in the standby database after creating a remote clone in the primary database, certain conditions must be met:
* Open PDBI (remote clone source) in Read Only (A): The source PDB from which the clone is created must be open in read-only mode to ensure a consistent state during cloning.
* Set STANDBY_PDB_SOURCE_FILE_DIRECTORY to <location of the PDB> in the london database (C): This parameter specifies the location on the standby database where the files from the source PDB should be placed.
* Set STANDBY_FILE_MANAGEMENT to auto in the london database (F): This parameter automates the management of file changes on the standby database when structural changes occur on the primary database, ensuring that the clone operation is reflected automatically on the standby.
