Topic #: 6
You are licensed to use Oracle Active Data Guard.

(Choose two.)

Suggested Answer: A,B Vote an answer

Explanation/Reference:
Explanation:
A: Many of the customers now are opting to perform RMAN backups on standby database to offload the resources of production database.
B: To enable Active Data Guard on a standby database, set the
ENABLE_OPTION_ACTIVE_DATA_GUARD initialization parameter to TRUE.
Note: Fast Incremental backups is possible with Block change tracking, which is initially introduced from version 10.2 onwards, by this tool it's very useful to reduce the RMAN incremental backup duration but it is limited only for Primary database. From 11g Oracle with Active Data Guard feature we can use Block change tracking even on Physical standby database.
