問題 #1

Examine the Data Guard configuration:
DGMGRL> show configuration:
Configuration Animals
Protection Mode: MaxAvailability
Databases:
dogs Primary database
sheep Logical standby database
cats Logical standby database
Fast-Start Failover: DISABLED
Configuration Status:
SUCCESS

A. Cats will be an enabled logical standby database.
B. Dogs will be a physical standby database.
C. Sheep will be the primary database.
D. Dogs will be a logical standby database.
E. Cats will be a disabled logical standby database.

問題 #2

The Oracle database 12c Observer is currently running on host1 and you wish to have it running on host2.
Examine this list of possible steps:
1) Stop the observer on host1.
2) Disable Fast-Start Failover.
3) Update the broker configuration with the new observer hostname.
4) Enable Fast-Start Failover.
5) Start the Observer on host2.
Which contains the minimum required steps to move the observer to host2?

A. Execute tasks 1, 2, 3, 4, and 5.
B. Execute tasks 1, 3, and 5.
C. Execute only task 5.
D. Execute tasks 1 and 5.

問題 #3

Which three are true about using RMAN in a Data Guard environment? (Choose three.)

A. Backups of archived redo logs taken on a physical standby are interchangeable with a primary.
B. A recovery catalog is required when RMAN is used to take backups from a logical standby database in a Data Guard configuration if you plan to recover the primary using those backups.
C. Backups of control files taken on a physical standby are not interchangeable with a primary.
D. Backups of data files taken on a physical standby are interchangeable with a primary.
E. A recovery catalog is required when RMAN is used to take backups from a physical standby database if you plan to recover the primary using those backups.

問題 #4

Your expertise is requested for these customer requirements:
1. The Data Guard environment must be in maximum protection mode.
2. Reports must be offloaded to a physical standby database.
3. There must be no lag between the primary and standby databases that affect the reports produced.
4. The primary database must be resilient in case of a single network failure.
Which solution is correct for these requirements?

A. two physical standby databases with Real-Time Query enabled, receiving redo from the primary with the LOG_ARCHIVE_DEST_n attributes SYNC NOAFFIRM to minimize the performance impact on the primary
B. two standby databases, at least one of them a physical standby with Real-Time Query enabled and the STANDBY_MAX_DELAY parameter set to zero, receiving redo from the primary with asynchronous transport
C. one physical standby database with Real-Time Query enabled and the
STANDBY_MAX_DATA_DELAY parameter set to zero, receiving redo from the primary with synchronous transport
D. two standby databases, at least one of them a physical standby with Real-Time Query enabled and the STANDBY_MAX_DATA_DELAY parameter set to zero, receiving redo from the primary with synchronous transport
E. one physical standby database with Real-Time Query enabled, receiving redo from two Far Sync instances that are connected the primary
