Question

A DevOps team adds automated load- and stress-testing capabilities to a CI/CD pipeline by using AWS CodeBuild. The team uses an Amazon Aurora MySQL DB cluster in a testing environment for load testing. The team configured the testing DB cluster with a minimum capacity of 1. The team uses 10 DB clusters in a production environment. All DB clusters are configured to automatically scale up to a maximum capacity of 15 Aurora Replicas. During load testing, the configuration of the Aurora DB cluster in the testing environment does not allow the cluster to scale quickly enough to satisfy transient demand, causing the load test to fail. The DevOps team must configure the DB cluster in the testing environment to satisfy the load-testing demand. Which solution will meet this requirement MOST cost-effectively?

Accepted Answer

B. Set the minimum capacity to 10 in the PRE_BUILD phase of the CodeBuild configuration. Reset the capacity to 1 in the POST_BUILD phase.

Answer

Set the minimum capacity to 10. Reduce the scale-in cooldown period in the PRE_BUILD phase of the CodeBuild configuration.

Answer

Set the minimum capacity to 10 in the POST_BUILD phase of the CodeBuild configuration. Reset the capacity to 1 in the same POST_BUILD phase.

Answer

Add an Amazon RDS Proxy in front of the testing Aurora DB cluster. Set the RDS Proxy endpoint in the PRE_BUILD phase of the CodeBuild configuration.
