Oracle Database 19c: Data Guard Administration Sample Questions (Q33-Q38):

NEW QUESTION # 33
Which three actions are performed by the START PLAN procedure of the DBMS ROLLING package?

A. switching the primary database to the logical standby role
B. converting the designated physical standby database into a logical standby database
C. starting media recovery on all the Leading Group Standby databases
D. building a LogMiner dictionary on the primary database instance
E. creating a guaranteed restore point on the standby databases
F. creating a guaranteed restore point on the primary database

Answer: D,E,F

Explanation:
The DBMS_ROLLING package facilitates a rolling upgrade process across a Data Guard configuration. The START PLAN procedure in particular handles several critical actions, including:
* Creating a guaranteed restore point on the standby databases (B): This ensures that the standby databases can be reverted to their state before the rolling upgrade process in case of any issues.
* Building a LogMiner dictionary on the primary database instance (C): This is necessary for logical standby databases to interpret redo data during the SQL Apply process.
* Creating a guaranteed restore point on the primary database (D): Similar to the standby databases, this ensures that the primary database can be reverted to a known good state if necessary.References:
* Oracle Database PL/SQL Packages and Types Reference
* Oracle Data Guard Concepts and Administration Guide

NEW QUESTION # 34
Which THREE are true about using flashback database in a Data Guard environment?

A. When a flashback database operation is performed on a primary database, a logical standby database is also flashed back automatically.
B. You can use it when real-time apply is enabled in case the phylt may not be used to flash back a primary database after a failover to a logical standby.
C. When a flashback database operation is performed on a primary database, a physical standby database is also flashed back automatically.
D. It may be used to flash back a physical standby that receives redo from a far sync instance.
E. You can use it when real-time apply is enabled in case the physical standby suffers from logical corruption.
F. It may not be used to flash back a primary database after a failover to a physical standby.

Answer: D,E,F

NEW QUESTION # 35
Which two statements are true regarding Data Guard environments in an Oracle Muti-tenant architecture?

A. Standby redo log files are required for each pluggable database that is protected with Data Guard.
B. The Data Guard broker may be used for multi-tenant databases.
C. A Data Guard environment with a multi-tenant primary database can operate in any Protection mode.
D. PDB_FILE_NAME CONVERT must be set to enable creation of standby databases if they are created on the same host as the primary.
E. Different redo transport methods can be configured for different pluggable databases within one Data Guard environment.

Answer: B,C

Explanation:
Oracle Multi-tenant architecture and Data Guard have several interactions, but specific aspects hold true in such environments:
* The Data Guard broker may be used for multi-tenant databases (B): Data Guard Broker simplifies the management and monitoring of Data Guard configurations and is fully compatible with the Oracle Multi-tenant architecture, allowing for easy management of Data Guard configurations that include multi-tenant container databases (CDBs) and their pluggable databases (PDBs).
* A Data Guard environment with a multi-tenant primary database can operate in any Protection mode (E): Data Guard can be configured to operate in Maximum Performance, Maximum Availability, or Maximum Protection mode, regardless of whether the primary database is a multi-tenant database.
This flexibility ensures that Data Guard can meet various data protection and availability requirements in multi-tenant environments.References:
* Oracle Data Guard Broker documentation
* Oracle Multitenant Administrator's Guide

NEW QUESTION # 36
Which THREE statements are TRUE about the supported workload in Active Data Guard standby databases?

A. You might have to use sequences with global temporary tables to support read-mostly applications by using Active Data Guard.
B. The DML operations on a standby can be transparently redirected to and run on the primary database
C. The DDL operations on private temporary tables are transparently redirected to the primary database.
D. PL/SQL blocks that you run on Active Data Guard standby databases can be always redirected to and run on the primary database.
E. Read-mostly reporting applications that use global temporary tables for storing temporary data can be offloaded.

Answer: A,B,E

Explanation:
In an Oracle Active Data Guard environment:
* B: Read-mostly reporting applications that utilize global temporary tables to store session-specific data can be effectively offloaded to an Active Data Guard standby database, reducing the load on the primary database.
* C: Sequences can be used with global temporary tables on an Active Data Guard standby database to support certain types of read-mostly applications, though some restrictions on sequence use may apply.
* E: In Oracle Database 19c and later, DML redirection allows DML operations performed on an Active Data Guard standby database to be transparently redirected to the primary database. This is part of the DML Redirection feature.
Option A is incorrect because not all PL/SQL blocks run on an Active Data Guard standby database can be redirected to the primary database. Some PL/SQL executions, specifically those that would attempt to make changes to the database, are not supported on the standby.
Option D is incorrect because DDL operations on private temporary tables are not redirected; instead, private temporary tables are session-specific and are not persisted on disk, so they do not generate redo and are not applicable to an Active Data Guard standby.
References: The behavior and capabilities of Active Data Guard standby databases are documented in the Oracle Data Guard Concepts and Administration guide and the Active Data Guard documentation.

NEW QUESTION # 37
The Oracle database 19c Observer is currently running on host1 and you wish to have it running on host2.
Examine this list of possible steps:
1) Stop the observer on host1
2) Disable Fast-Start Failover
3) Update the broker configuration with the new observer hostname
4) Enable Fast-Start Failover
5) Start the Observer on host2
Which contains the minimum required steps to move the observer to host2?

A. Execute tasks 1, 2, 3, 4, and 5
B. Execute tasks 1 and 5
C. Execute tasks 1, 3, and 5
D. Execute only task 5

Answer: C

Explanation:
* Stop the Observer on host1 to ensure that there are no conflicts between the instances of the Observer running on different hosts.
* Update the Data Guard Broker configuration with the new hostname for the Observer. This step is crucial to redirect the Data Guard Broker to communicate with the Observer on the new host.
* Start the Observer on host2 to resume its operations in the new environment.
Disabling and re-enabling Fast-Start Failover (steps 2 and 4) are not strictly necessary for moving the Observer to a new host. These steps would be more relevant if changes to the configuration of Fast-Start Failover itself were required, which is not the case when simply relocating the Observer.
