Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.

Create a cross-region read replica
Why this is correct
A cross-region replica provides near-real-time data in another region for failover.
- ✗
Set up a same-region read replica
Why it's wrong here
Same-region does not help with regional outage.
- ✓
Enable binary logging with a PITR retention period
Why this is correct
PITR allows recovery to within minutes by replaying binary logs.
- ✗
Enable automatic storage increase
