AWS Certified Solutions Architect – Professional — Question 902

You have set up Auto Scaling to automatically scale in. Consequently, you must decide which instances Auto Scaling should end first.
What should you use to configure this?

Answer options

• A. An Elastic Load Balancer
• B. A termination policy
• C. An IAM role
• D. Another scaling group

Correct answer: B

Explanation

A termination policy allows you to specify the criteria that Auto Scaling uses to decide which EC2 instances to terminate first when scaling in. Other options like Elastic Load Balancers, IAM roles, and additional scaling groups do not govern instance termination order during scale-in events.
