AWS Certified Solutions Architect – Professional — Question 588

To scale out the AWS resources using manual AutoScaling, which of the below mentioned parameters should the user change?

Answer options

• A. Current capacity
• B. Desired capacity
• C. Preferred capacity
• D. Maximum capacity

Correct answer: B

Explanation

To perform manual scaling in an AWS Auto Scaling group, the user must update the Desired capacity parameter, which instructs the service to launch or terminate instances to meet the new target. Current capacity is a read-only status metric, and Maximum capacity only sets the boundary limit rather than triggering an immediate manual scale-out. Preferred capacity is not a valid parameter in AWS Auto Scaling.
