Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
By provisioning multiple availability domains dynamically behind the scenes.
Why it's wrong here
Single-AD regions physically contain only one availability domain.
- ✗
By requiring users to manually peer across international regions.
Why it's wrong here
This is for disaster recovery, not regional high availability.
- ✓
By utilizing multiple fault domains within that single availability domain.
Why this is correct
Fault domains provide hardware fault isolation within single-AD regions.
- ✗
High availability is not possible in single-AD regions.
Why it's wrong here
Fault domains provide high availability within single-AD regions.
