DBS-C01 Monitoring and Troubleshooting Practice Question
Arrange the steps to set up cross-Region read replicas for an Amazon Aurora MySQL DB cluster in the correct order.
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
✓
Enable binary logging on the source Aurora MySQL DB cluster, then create a cross-Region read replica in the target Region, then verify replication status.
Cross-Region replicas require binary logging enabled on the source, then creating a read replica in another Region and verifying replication.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Enable binary logging on the source Aurora MySQL DB cluster, then create a cross-Region read replica in the target Region, then verify replication status.
Why this is correct
This is the correct order because cross-Region replication requires binary logging to be enabled on the source before creating a read replica in a different AWS Region, and verifying replication ensures it is working correctly.
- ✗
Create a cross-Region read replica in the target Region, then enable binary logging on the source cluster, then verify replication.
Why it's wrong here
This is incorrect because binary logging must be enabled on the source before creating a cross-Region replica; otherwise, the replica creation will fail or replication won't work.
- ✗
Enable binary logging on the source cluster, then promote the read replica to a standalone cluster, then verify replication.
Why it's wrong here
This is incorrect because promoting a read replica makes it a standalone cluster and stops replication, which is not part of setting up cross-Region replicas; the goal is to maintain replication, not promote.
- ✗
Create a read replica in the same Region, then enable cross-Region replication by modifying the source cluster, then verify.
Why it's wrong here
This is incorrect because setting up cross-Region replicas requires creating the replica directly in another Region, not in the same Region, and there is no such step as enabling cross-Region replication by modifying the source cluster after creating a same-Region replica.
