[All AWS-SysOps Questions]

A user is using a small MySQL RDS DB. The user is experiencing high latency due to the Multi AZ feature. Which of the below mentioned options may not help the user in this situation?

  • A. Schedule the automated back up in non-working hours
  • B. Use a large or higher size instance
  • C. Use PIOPS
  • D. Take a snapshot from standby Replica
Show Suggested Answer Hide Answer
Suggested Answer: D 🗳️
An RDS DB instance which has enabled Multi AZ deployments may experience increased write and commit latency compared to a Single AZ deployment, due to synchronous data replication. The user may also face changes in latency if deployment fails over to the standby replica. For production workloads, AWS recommends the user to use provisioned IOPS and DB instance classes (m1.large and larger. as they are optimized for provisioned IOPS to give a fast, and consistent performance. With Multi AZ feature, the user can not have option to take snapshot from replica.

Selected Answer: B
I say B because I can rule out other options. As for D, how many times in a day would you take a snap ? once ? twice ? The question says that the user is facing constant slowness.
