Oracle Database 19c: Data Guard Administration Sample Questions (Q52-Q57):NEW QUESTION # 52
Which TWO are TRUE about offloading backups to a physical standby database in a Data Guard environment?
  • A. The standby database can not be registered in an RMAN catalog if the primary database has not been registered.
  • B. The standby database must be registered in an RMAN catalog after the primary database has been registered.
  • C. The standby database must be registered in an RMAN catalog before the primary database has been registered.
  • D. Backups of the standby control file taken while connected to the catalog where the database is registered, may be used to restore the control file on the primary database.
Answer: B,D
Explanation:
In a Data Guard environment, offloading backups to a physical standby database has certain requirements:
A: Once the primary database is registered in an RMAN catalog, the standby database can also be registered. This allows RMAN to manage backups coherently across both databases and leverage the standby database for backup purposes without interfering with the primary database's workload.
C: Backups of the standby control file taken while connected to the catalog where the database is registered can be used to restore the control file on the primary database. This ensures that backup metadata is consistent across the Data Guard configuration.
Options B and D are incorrect because there is no strict requirement for the order in which the primary and standby databases must be registered in an RMAN catalog. However, it is a common practice to register the primary database first.

NEW QUESTION # 53
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 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
  • C. A physical standby database with synchronous redo transport that can be converted regularly into a snapshot standby 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: C
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 # 54
You must configure an Oracle Data..........
1. A primary database
2. A physical standby database
Examine these requirements: 1. Data loss is not permitted.
1. Data loss is not permitted.
2. It should be possible to convert the physical standby database to a snapshot standby database.
3. Under normal operations, transactions should commit when redo is written to disk on the primary database and as soon as it has been received by the standby database instance.
4. The availability of the primary database should not be compromised by the availability of the standby database.
5. It should be possible to convert the physical standby database to a logical standby database
6. It should be possible to deploy Real Application Clusters on the primary database.
7. It should be possible to deploy Real Application Clusters on the physical standby database.
You configure SYNC redo transport mode in combination with Maximum Protection mode.
  • A. 1, 2, 6, and 7
  • B. 1, 2, 3, 6, and 7
  • C. 1, 2, 3, 4, 5, 6, and 7
  • D. 1, 2, and 5
  • E. 1, 6, and 7
Answer: C
Explanation:
When SYNC redo transport mode is combined with Maximum Protection mode, it ensures that no data loss will occur (requirement 1). The physical standby can be converted to a snapshot standby (requirement 2) and later to a logical standby database (requirement 5), satisfying both transformation requirements. Transactions commit as soon as redo data is received by the standby database (requirement 3). The availability of the primary is not dependent on the standby database in Maximum Protection mode, as the primary database will halt if the standby cannot acknowledge the redo (requirement 4), thus indirectly ensuring its availability. It is also possible to deploy Real Application Clusters on both the primary (requirement 6) and the physical standby database (requirement 7), providing high availability and scalability.

NEW QUESTION # 55
Examine the fast-start failover configuration:

  • A. The observer will initiate a failover when the primary database is unable to produce local archived redo log files.
  • B. A failover may occur if the observer has lost connectivity to the primary database, even if the Fast-Start Failover target standby database has a good connection to the primary database
  • C. If South_Sales develops a problem and cannot be the target of a failover, the broker automatically changes the fast-start failover target to one of the other candidate targets.
  • D. You must disable fast-start failover first to change the fast-start failover target to East sales.
  • E. The observer is running.
Answer: A,B,E

NEW QUESTION # 56
Which TWO statements are true about database parameters for databases in a Data Guard environment?
  • A. LOG_FILE_NAME_CONVERT applies to online redo logs and archived logs.
  • B. The databases that are part of a Data Guard configuration must have different DB_UNIQUE_NAME initialization parameters.
  • C. DB_FILE_NAME_CONVERT is only required if the standby database is on the same host as the primary database.
  • D. If DB_RECOVERY_FILE_DEST is specified, then LOG_ARCHIVE_DEST_n is not required for local archive logs.
  • E. COMPATIBLE must have identical values for primary and standby databases.
Answer: B,E
