Oracle Exam 1Z0-066 Topic 7 Question 25 Discussion
Topic #: 7
A Data Guard environment has this configuration and these attributes:
1. A primary database
2. A Physical Standby Database named sbdb
3. The configuration is in maximum availability protection mode.
Then sbdb is converted to a snapshot standby database.
When two statements are true? (Choose two.)
E: A snapshot standby database receives and archives, but does not apply, redo data from a primary database.
D: Snapshot standby databases are best used in scenarios where the benefit of having a temporary, updatable snapshot of the primary database justifies additional administrative complexity and increased time to recover from primary database failures.
Note: Redo data received from the primary database is applied when a snapshot standby database is converted back into a physical standby database, after discarding all local updates to the snapshot standby database.
The data in the primary database is fully protected however, because a snapshot standby can be converted back into a physical standby database at any time, and the redo data received from the primary will then be applied.
