Oracle Database 19c: Data Guard Administration Sample Questions (Q19-Q24):NEW QUESTION # 19
You created a physical standby database prodsbyi from the primary database prod using SQL and RMAN.
Which THREE are prerequisites for creating a Data Guard Broker configuration to manage these databases?
  • A. The DG_BROKER_START parameter must be set to TRUE for both database instances.
  • B. The primary database must have FORCE LOGGING enabled.
  • C. The standby database must have supplemental logging enabled.
  • D. A local net service name to enable connectivity to the PRODSBYI database instance must be defined on the primary database host.
  • E. The primary database must have supplemental logging enabled.
  • F. The LOG_ARCHIVE_DEST_n parameters with the service attribute set must be cleared.
Answer: A,D,E
Explanation:
When setting up a Data Guard Broker configuration for a primary database and its physical standby, the following prerequisites must be met:
* A: Oracle Net connectivity must be defined on both the primary and standby hosts to enable the respective database instances to communicate with each other.
* B: Supplemental logging is required on the primary database because it provides additional logging necessary for the standby database to be able to apply changes from the primary database accurately.
* F: The DG_BROKER_START parameter must be set to TRUE for both the primary and standby
* database instances. This parameter is used to start the Data Guard Broker process which manages the configuration.
Options C and D are not prerequisites for creating a Data Guard Broker configuration. Additionally, while FORCE LOGGING mode (option E) is recommended as a best practice to prevent possible data inconsistencies during media recovery, it is not a strict prerequisite for creating a Data Guard Broker configuration.
References: This guidance is based on Oracle's best practices for setting up Data Guard configurations, as found in the Oracle Data Guard Broker documentation and the Oracle Data Guard Concepts and Administration guide.

NEW QUESTION # 20
Which three actions are performed by the START PLAN procedure of the DBMS ROLLING package?
  • A. building a LogMiner dictionary on the primary database instance
  • B. switching the primary database to the logical standby role
  • C. creating a guaranteed restore point on the primary database
  • D. converting the designated physical standby database into a logical standby database
  • E. starting media recovery on all the Leading Group Standby databases
  • F. creating a guaranteed restore point on the standby databases
Answer: A,C,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.

NEW QUESTION # 21
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. 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.
  • C. 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.
  • D. Configure a PRIMARY role service on the Primary and Standby and modify the Client connect descriptor to include both the Primary and the Standby.
Answer: B

NEW QUESTION # 22
Which three statements are true about redo transport?
  • A. With synchronous redo transport, LGWR ships redo directly to RFS processes on the standby database instances and waits for an acknowledgment.
  • B. With asynchronous redo transport, TTnn processes may read redo from the log buffer or from standby redo logs on the primary database.
  • C. Multiple RFS processes may receive redo on one standby database instance.
  • D. An RFS process on a standby database instance may receive redo from an archiver process on the primary database instance to perform archive gap resolution.
  • E. Multiple RFS processes may receive redo on one far sync instance.
Answer: A,C,D

NEW QUESTION # 23
Which three statements are true about Data Guard database modes and states?
  • A. Databases in a Data Guard Configuration need not operate in Flashback Logging mode.
  • B. Force Logging Mode is not required for a primary database but is recommended.
  • C. The Primary Database can operate in noarchivelog mode.
  • D. A primary database may ship redo directly to more than nine standby databases.
  • E. A Logical Standby Database can be in MOUNT state while applying changes.
Answer: A,B,E
