質問 2：
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. 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. 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.
D. 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.
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.
正解：C

質問 3：
Which three are true concerning archive logs in a Data Guard Environment? (Choose three.)
A. A far sync instance writes to the LOG_ARCHIVE_DEST directory if the remote physical standby database instance to which it routes redo, is not reachable.
B. A far sync instance writes to the LOG_ARCHIVE_DEST directory if the remote logical standby database instance to which it routes redo, is not reachable.
C. A logical standby database chooses an appropriate location for writing its own standby archive logs automatically.
D. A physical standby database instance chooses an appropriate location for writing its own standby archive logs automatically.
E. A logical standby database instance writes online redo logs.
F. A physical standby database instance writes online redo logs.
正解：A,C,D

質問 4：
You must configure an Oracle Data Guard environment consisting of:
1. A primary database
2. Three Physical Standby Databases
You must meet these requirements:
1. A designated physical standby database should become the primary database automatically whenever the primary database fails.

Which redo transport mode and protection mode would you configure to meet these requirements?
A. SYNC AFFIRM and Maximum Protection
B. SYNC AFFIRM and Maximum Availability
C. ASYNC and Maximum Performance
D. SYNC NOAFFIRM and Maximum Protection
E. SYNC NOAFFIRM and Maximum Availability

C. It can be used to show properties of a pluggable primary database.
D. It can be used to show properties of a far sync instance.

質問 6：
Which three are true regarding the Enterprise Manager Cloud Control Data Guard configuration verification wizard? (Choose three.)
A. It modifies the database configurable parameters to match the values set for the broker configuration.
B. It generates a workload on the primary database causing log switching, and monitors the arrival rate of redo on the standby database.
C. It checks that the current data protection level is consistent with the broker's configured data protection mode.
D. It verifies that parameter settings in the SPFILE or in memory or both, are consistent with the broker configuration properties for that database.
E. It checks that supplemental logging is turned on if there is a logical standby database in the configuration.
