[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company uses an Amazon RDS for MySQL instance. To prepare for end-of-year processing, the company added a read replica to accommodate extra read-only queries from the company's reporting tool. The read replica CPU usage was 60% and the primary instance CPU usage was 60%.

After end-of-year activities are complete, the read replica has a constant 25% CPU usage. The primary instance still has a constant 60% CPU usage. The company wants to rightsize the database and still provide enough performance for future growth.

Which solution will meet these requirements?

  • A. Delete the read replica Do not make changes to the primary instance
  • B. Resize the read replica to a smaller instance size Do not make changes to the primary instance
  • C. Resize the read replica to a larger instance size Resize the primary instance to a smaller instance size
  • D. Delete the read replica Resize the primary instance to a larger instance

Answer is B Since the read replica is now underutilized with only 25% CPU usage, it can be resized to a smaller instance to save costs while still handling the reduced read queries. No changes to the primary instance are needed, as it is consistently running at 60% CPU usage, which is manageable, and the read replica will still offload read queries in the future.
