A company uses an Amazon Aurora PostgreSQL global database that has two secondary AWS Regions. A DevOps engineer has configured the database parameter group to guarantee an RPO of 60 seconds. Write operations on the primary cluster are occasionally blocked because of the RPO setting. The DevOps engineer needs to reduce the frequency of blocked write operations. Which solution will meet these requirements?

Answer options

A: Add an additional secondary cluster to the global database.

B: Enable write forwarding for the global database.

C: Remove one of the secondary clusters from the global database.

D: Configure synchronous replication for the global database.

Correct Answer:

C Step 1: Reducing Replication Lag in Aurora Global Databases In Amazon Aurora global databases, write operations on the primary cluster can be delayed due to the time it takes to replicate to secondary clusters, especially when there are multiple secondary regions involved. Issue: The write operations are occasionally blocked due to the RPO setting, which guarantees replication within 60 seconds. Action: Remove one of the secondary clusters from the global database. Why: Fewer secondary clusters will reduce the overall replication lag, improving write performance and reducing the frequency of blocked writes. Reference: AWS documentation on Aurora Global Database. This corresponds to Option C: Remove one of the secondary clusters from the global database.
