Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Snapshot Standby
Why it's wrong here
Snapshot Standby converts a physical standby into a read-write database temporarily, stopping redo apply until converted back.
- ✓
Active Data Guard
Why this is correct
Active Data Guard allows the physical standby database to be open in read-only mode for queries and reporting while receiving redo apply.
- ✗
Logical Standby in read-write mode
Why it's wrong here
Logical standby applies SQL rather than redo and introduces architectural complexity compared to Active Data Guard for physical standbys.
- ✗
Traditional Physical Standby (Mount mode)
Why it's wrong here
In traditional mount mode, the database cannot be queried while applying redo.
