PCDE Practice Question: Manage a solution that can span multiple database technologies
A company has a Cloud SQL for MySQL instance with a cross-region read replica for disaster recovery. During a regional outage, they need to promote the read replica to a standalone instance as quickly as possible. What is the correct procedure?
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
✓
Use the gcloud sql instances promote-replica command on the replica
Promoting a read replica makes it a standalone instance. It can be done via the Cloud Console or gcloud command. The promotion is immediate, but the original primary may still be active if not stopped.
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 backup of the replica and restore it as a new instance
Why it's wrong here
This would take longer and is not the recommended DR procedure.
- ✗
Delete the read replica and restore a backup from the primary as a new instance
Why it's wrong here
This is slower and unnecessary; promotion is the intended action.
- ✓
Use the gcloud sql instances promote-replica command on the replica
Why this is correct
Correct. The promote-replica command promotes the replica to a standalone instance.
- ✗
Stop replication on the replica by issuing STOP SLAVE on the instance
Why it's wrong here
Stopping replication does not promote it; it remains a replica that can be promoted later.
