PCDE Practice Question: Manage a solution that can span multiple database technologies
A company has a Cloud SQL for PostgreSQL instance with a read replica in another region. They want to perform disaster recovery testing without affecting the primary. What should they do?
⚠ Common exam trap
Candidates often assume read replicas are permanently read-only and cannot be used for testing, or they confuse promoting a replica with cloning the primary, which would impact the primary's performance.
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
✓
Promote the read replica to a standalone instance and use it for testing.
Promoting the read replica to a standalone instance detaches it from the primary, creating an independent writable Cloud SQL instance. This allows you to perform disaster recovery testing (e.g., failover validation, data integrity checks) without any impact on the primary instance, as the replica no longer replicates changes from the primary.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Promote the read replica to a standalone instance and use it for testing.
Why this is correct
Promoting the replica makes it an independent instance, suitable for DR testing.
- ✗
Use the replica as a failover target; testing is not allowed.
Why it's wrong here
Replicas can be promoted for testing.
- ✗
Enable point-in-time recovery on the replica and restore to a new instance.
Why it's wrong here
Replicas cannot have separate PITR; they follow the primary's logs.
- ✗
Create a clone of the primary instance and test on that.
Why it's wrong here
This affects production performance and involves creating a new instance from backup.
