Oracle Database 12c: Data Guard Administrator Sample Questions:

Question #1

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. 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.
  • B. 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.
  • C. 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.
  • D. 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.
  • E. 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.
