AWS Certified SysOps Administrator – Associate (legacy) — Question 471

Which service is offered by Auto Scaling?

Answer options

• A. Automatic scaling storage
• B. Automatic scale EC2 capacity
• C. Automatic scale ECS capacity
• D. Automatic scale elastic IP

Correct answer: B

Explanation

Amazon EC2 Auto Scaling is designed to automatically launch or terminate Amazon EC2 instances to maintain application availability based on defined conditions. While other AWS services have their own scaling mechanisms, the primary function of the core Auto Scaling service is managing EC2 capacity. It does not natively scale standalone storage volumes or Elastic IP addresses.
