Strategies to help you tackle Oracle Database 19c: Data Guard Administration exam questions effectively
Allocate roughly 1-2 minutes per question. Flag difficult questions and return to them later.
Pay attention to keywords like 'MOST', 'LEAST', 'NOT', and 'EXCEPT' in questions.
Use elimination to narrow down choices. Often 1-2 options can be quickly ruled out.
Focus on understanding why answers are correct, not just memorizing facts.
Practice with real exam-style questions for Oracle Database 19c: Data Guard Administration
A basic Data Guard configuration requires a primary database, at least one standby database (physical or logical), and Oracle Net configuration to enable communication between the primary and standby databases. Oracle GoldenGate is not required for Data Guard. Having both physical and logical standbys is optional, not required. RMAN is useful but not a required component for Data Guard configuration.
Maximum Protection mode ensures zero data loss by requiring that redo data be written to at least one synchronized standby database before transactions can commit on the primary. If no synchronized standby is available, the primary database will shut down. Maximum Availability provides zero data loss protection but allows the primary to continue if standbys become unavailable. Maximum Performance allows asynchronous redo transport for better performance but with potential data loss. Maximum Security is not a valid Data Guard protection mode.
V$DATAGUARD_STATS provides detailed statistics about Data Guard operations including apply lag, transport lag, and other performance metrics. This view is specifically designed for monitoring Data Guard synchronization. V$DATAGUARD_STATUS shows status messages but not detailed lag statistics. V$ARCHIVE_DEST shows archive destination configuration. V$DATABASE contains general database information but not specific Data Guard lag metrics.
During a switchover operation, roles are reversed in a planned manner. The original primary database becomes a standby database, and the target standby database becomes the new primary. This is a reversible operation with no data loss. The original primary is not shut down permanently, does not remain in primary role, and is not deleted from the configuration.
The SYNC redo transport mode sends redo data synchronously to the standby and waits for acknowledgment that the data has been written to the standby redo logs before the primary transaction commits. ASYNC sends redo asynchronously without waiting. NOAFFIRM and AFFIRM control whether the transport process waits for disk I/O completion, but SYNC is the primary attribute that determines synchronous behavior. ARCH mode uses the archiver process for asynchronous transport.
