Oracle Database 12c: Data Guard Administrator Sample Questions:
You must propose an Oracle Data Guard configuration for a database supporting a DSS workload that meets these permanent requirements:
1. The performance impact on the primary database should be kept to a minimum.
2. Creating and maintaining materialized views should not impact the performance of the primary database.
Additionally, there are these requirements, only the one of which is ever done at any one time:
3. It should be possible to apply designated patches with a minimum amount of downtime.
4. Upgrading to a new database release should be performed with the least possible amount of downtime.
5. New application software releases should be tested against an exact up-to-date replica of the production database.
You propose a configuration operating in Maximum Performance mode with a primary database and one logical standby database.
Which requirements do you meet?
- A. 1, 2, 3, 4, and 5
- B. 1 and 5
- C. 1, 2, and 3
- D. 2, 3, and 5
- E. 2 and 5
- F. 1, 2, and 4
Correct Answer: F 🗳️
Which two statements are true for Data Guard environments with multi-tenant databases? (Choose two.)
- A. A pluggable database within a multi-tenant standby database can have a different open mode than the container database.
- B. DB_UNIQUE_NAME must be specified differently for each pluggable database within a multi-tenant standby database.
- C. Each pluggable database within a multi-tenant physical standby database has a minimum of one associated Oracle Net service name.
- D. Each pluggable database within a multi-tenant physical standby has one MRP background process running during redo apply.
- E. A pluggable database within a multi-tenant standby database can have a different database role than the container database.
Correct Answer: A,B 🗳️
You have a Data Guard Broker configuration called 'Somewhere' as shown:
DGMGRL> SHOW CONFIGURATION;
Configuration Somewhere
Protection Mode: MaxPerformance
Databases:
Nearby Primary database
FS Far Sync
Farout Physical standby database
Fast-Start Failover: DISABLED
Configuration Status:
SUCCESS
You then run this command:
DGMGRL > SHOW DATABASE 'Nearby' 'InconsistentProperties';
Which two are true about the output of this DGMGRL command? (Choose two.)
- A. A far sync instance cannot have inconsistent properties because it has no database.
- B. Any inconsistency reported is on an instance-specific basis.
- C. It shows all properties whose broker configuration values for database Nearby are inconsistent with the values in the corresponding server parameter file or the runtime values for database instance Nearby.
- D. It shows all properties whose broker configuration values for database Nearby are inconsistent with the broker configuration values for database Farout.
Correct Answer: B,C 🗳️

Examine the Data Guard configuration:
DGMGRL> show configuration;
Configuration - Animals
Protection Mode: MaxAvailability
Databases:
dogs - Primary database
sheep - (*) Physical standby database
cats - Physical standby database
Fast-Start Failover: ENABLED
Configuration Status:
SUCCESS
What happens if you issue "switchover" to sheep;" at the DGMGRL prompt?
- A. The switchover succeeds but Dogs need to be reinstated.
- B. It results in an error indicating that a switchover is not allowed.
- C. The switchover succeeds and Cats become the new failover target.
- D. The switchover succeeds and Dogs become the new failover target.
- E. The switchover succeeds but Fast-Start Failover is suspended.
Correct Answer: D 🗳️
You have a Data Guard broker configuration consisting of:
1. A primary database
2. One local physical standby database
3. One far sync instance
4. A remote physical standby database
The broker configuration was created with the DGMGRL utility after creating all the databases and the far sync instance with command-line tools.
What is the correct way to add this configuration to Enterprise Manager Cloud Control assuming all the nodes have been discovered already as Enterprise Manager targets?
- A. Discover the primary database as a target in Enterprise Cloud Control. Then discover the existing Data Guard Broker configuration for the primary and all the other databases in the configuration will be discovered as targets and be ready to be monitored.
- B. Delete the Data Guard Broker configuration using DGMGRL and then re-create it using Enterprise Manager Cloud Control to enable all the databases in the configuration to be discovered as targets and to be ready to be monitored.
- C. Discover either of the physical standby databases as a target by refreshing the node on which they run, and the other databases and instances in the Data Guard Broker configuration will be discovered as targets automatically and be ready to be monitored.
- D. Discover the primary as a target by refreshing the node on which it runs, and the other databases and instances in the Data Guard Broker configuration will be discovered as targets automatically and be ready to be monitored.
- E. Use the DGMGRL utility to register the configuration with the Enterprise manager Cloud Control agent on the primary database node. This will enable the discovery of all the other databases in the configuration as targets which will be ready to be monitored.
