AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

A company uses a single AWS CloudFormation template to deploy a three-tier application that includes Auto Scaling groups and a production Amazon RDS instance. During routine maintenance, an operations engineer must update the stack to patch the application servers. Company policy states that the update must never replace or delete the existing RDS instance. If the template change would cause a replacement, the operation must immediately fail before any resources are modified so the engineer can investigate. Which approach meets these requirements with the least operational effort?

  • Generate a change set, review it for replacement actions on the RDS resource, and execute the change set only if none are found.

  • Add the DeletionPolicy and UpdateReplacePolicy attributes with a value of Retain to the RDS resource before updating the stack.

  • Attach a stack policy that denies all Update:* actions on the RDS resource and then update the stack.

  • Manually create an RDS snapshot and proceed with the stack update; restore from the snapshot if the database is replaced.
