Oracle Database 19c: Data Guard Administration Sample Questions (Q60-Q65):NEW QUESTION # 60
Which two are true about the use of RMAN recovery catalogs when offloading backups to a physical standby database?
  • A. Primary and physical standby databases may use different virtual recovery catalogs in the same physical recovery catalog.
  • B. The physical standby database may be used to register the database in the recovery catalog, if the primary is not registered.
  • C. It backups that are offloaded to a physical standby database are taken when not connected to a recovery catalog, then they may still be used for restoration on the primary database.
  • D. It is not necessary to use a recovery catalog unless a far sync instance is used to route redo to the physical standby database.
  • E. The primary and physical standby databases must be registered separately in the recovery catalog, if a far sync instance is used to route redo to the physical standby database.
Answer: A,C

NEW QUESTION # 61
Which three Data Guard monitoring activities may be performed using Enterprise Manager Cloud Control?
  • A. You can check the potential data loss in the event of a disaster.
  • B. You can set a critical threshold on the redo generation rate metric for a primary database.
  • C. You can monitor the redo apply rate on a logical standby database.
  • D. You can check if redo apply needs to be tuned.
  • E. You can monitor the redo apply rate on a snapshot standby database.
  • F. You can set a warning threshold on the redo generation rate metric for a physical standby database.
Answer: A,B,C
Explanation:
Enterprise Manager Cloud Control offers comprehensive monitoring capabilities for Oracle Data Guard environments. It enables monitoring the rate at which redo is being applied on a logical standby database (A), which is crucial for ensuring that the standby database is keeping up with the changes from the primary. It also allows setting thresholds on performance metrics, such as the redo generation rate on the primary database (B), to alert administrators when values exceed critical or warning thresholds. Additionally, it provides the capability to estimate the potential data loss in the event of a disaster (E), helping in disaster recovery planning and ensuring business continuity.
References:Oracle Enterprise Manager Cloud Control documentation provides extensive information on its monitoring features for Oracle Data Guard, including setting thresholds, estimating potential data loss, and tracking redo apply rates.

NEW QUESTION # 62
You must propose an Oracle Data Guard configuration for a database supporting an OLTP workload that meets these permanent requirements:
Data loss is not permitted.
Read-only applications should not connect to the primary database instance.
Additionally, there are these requirements, only one of which is ever done at any one time:
It should be possible to apply and test designated patches with a minimum amount of downtime.
Upgrading to a new database release should be performed with the least possible amount of downtime.
New application software releases should be tested against an exact up-to-date replica of the production database.
You propose a primary database with one physical standby database configured in Maximum Protection mode.
Which requirements do you meet?
  • A. 2, 3, 4, and 5
  • B. Only requirement 5
  • C. Only requirement 1
  • D. 1, 2, 3, 4, and 5
  • E. 1 and 2
Answer: C

NEW QUESTION # 63
Which THREE statements are true about snapshot standby databases?
  • A. A snapshot standby database may be opened read-only.
  • B. FLASHBACK DATABASE is enabled automatically on a physical standby database as part of the conversion into a snapshot standby database, if not already enabled.
  • C. A snapshot standby database can have Real-Time apply enabled.
  • D. FLASHBACK DATABASE must be manually enabled on a physical standby database before converting it into a snapshot standby database.
  • E. FLASHBACK DATABASE is enabled automatically on a snapshot standby database after converting it from a physical standby database if not already enabled.
  • F. A snapshot standby database may be opened read-write.
Answer: B,E,F
Explanation:
Snapshot standby databases are a feature of Oracle Data Guard that allows a physical standby database to be temporarily converted into a read-write database for testing or other purposes. The true statements about snapshot standby databases are:
FLASHBACK DATABASE is enabled automatically on a snapshot standby database after converting it from a physical standby database if not already enabled (B): When a physical standby is converted to a snapshot standby, FLASHBACK DATABASE is automatically enabled to allow the database to be easily reverted back to its original state.
FLASHBACK DATABASE is enabled automatically on a physical standby database as part of the conversion into a snapshot standby database, if not already enabled (C): As part of the conversion process, FLASHBACK DATABASE is turned on to ensure that changes made while the database is in snapshot standby mode can be undone.
A snapshot standby database may be opened read-write (E): Once a physical standby is converted to a snapshot standby, it can be opened for read-write operations, allowing for testing and other tasks that require a writable database.

NEW QUESTION # 64
There are currently 6 applief. and 6 pfepafef processes running and no idle applier processes on y logical standby database.
The max_SERVERS SQL apply parameter and number of archiver processes are both set to 12.
Identify two changes, each of which would allow you to increase the number of applier processes.
  • A. Increase the parallel_max_server initialization parameter.
  • B. Decrease the number of archiver processes on the standby database.
  • C. Increase the processes initialization parameter. D Decrease the number of FREPARER processes.
  • D. Increase the RECOVERY_PARALLEL initialization parameter.
  • E. Increase the value for the MAX_SERVERS SQL apply parameter.
Answer: A,E
Explanation:
To increase the number of applier processes on a logical standby database, the following changes can be made:
C: Increasing the value for the MAX_SERVERS SQL apply parameter would allow for more applier processes to be initiated, assuming that system resources permit.
D: Increasing the PARALLEL_MAX_SERVERS initialization parameter would allow for more parallel execution processes, which can be used by SQL apply to increase the number of applier processes.
Option A is incorrect as decreasing the number of archiver processes will not necessarily increase the number of applier processes; these are unrelated components.
Option B is incorrect because the 'FREPARER' processes do not exist, it seems to be a typographical error, and the 'REPARER' is not a valid Oracle process or parameter.
Option E is incorrect because the RECOVERY_PARALLELISM parameter controls the number of processes used for instance recovery and media recovery, not for SQL apply.
