AWS Certified SysOps Administrator – Associate (legacy) — Question 55

A company would like to review each change in the infrastructure before deploying updates in its AWS CloudFormation stacks.
Which action will allow an Administrator to understand the impact of these changes before implementation?

Answer options

• A. Implement a blue/green strategy using AWS Elastic Beanstalk.
• B. Perform a canary deployment using Application Load Balancers and target groups.
• C. Create a change set for the running stack.
• D. Submit the update using the UpdateStack API call.

Correct answer: C

Explanation

Creating a change set for the running stack allows the Administrator to preview the changes that will be made, helping to assess their impact before deployment. The other options focus on different deployment methods or processes that do not provide a review mechanism for upcoming changes.
