1Z0-060 Question #216: Real Exam Question with Answer & Explanation

The correct answer is A: when a registered database is opened with the RESETLOGS option. The RMAN recovery catalog is automatically resynchronized when a registered database opens with RESETLOGS and when control file metadata ages out per the retention policy.

Question

In which two scenarios is an RMAN recovery catalog automatically resynchronized? (Choose two.)

Options

Awhen a registered database is opened with the RESETLOGS option
Bwhen a redo log is archived
Cwhen backup metadata records are aged out of the control file based on the
Dwhen the backup retention policy configuration is changed for a registered database
Ewhen a manual redo log switch is performed

Explanation

The RMAN recovery catalog is automatically resynchronized when a registered database opens with RESETLOGS and when control file metadata ages out per the retention policy.

Common mistakes.

B. Archiving a redo log does not trigger an automatic recovery catalog resynchronization; archived log metadata is recorded in the catalog during subsequent backup operations or an explicit RESYNC CATALOG command.
D. Changing the backup retention policy configuration does not automatically resynchronize the catalog; a manual RESYNC CATALOG command is required to propagate such configuration changes.
E. A manual redo log switch does not trigger automatic recovery catalog resynchronization; log switches are local, control-file-level events that do not directly cause catalog updates.

Concept tested. RMAN recovery catalog automatic resynchronization triggers
