Network Topology
Refer to the exhibit. An administrator wants to ensure that during a regional outage, the failover group automatically fails over without data loss if possible. What is the current configuration gap?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The backup storage redundancy is Local, which does not provide geo-redundancy for backups.
Automatic failover with data loss grace period is set to 60 minutes. The backup redundancy is Local, which means backups are stored only in the primary region. If a regional disaster occurs, backups might be lost. Geo-redundant backups would be needed to recover in the secondary region without data loss.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The failover policy is set to Automatic, but the grace period is too long.
Why it's wrong here
Grace period is acceptable; the issue is backup redundancy.
- ✓
The backup storage redundancy is Local, which does not provide geo-redundancy for backups.
Why this is correct
Geo-redundant backup storage (GRS) is needed to protect backups across regions.
- ✗
The secondary managed instance mi2 is in the same region as the primary.
Why it's wrong here
Secondary is in westus, primary in eastus; different regions.
- ✗
The read-only endpoint failover policy is Disabled, which prevents read-only traffic after failover.
Why it's wrong here
Read-only failover policy is not required for automatic failover.
