AWS Certified Cloud Practitioner — Question 398

A company is launching a new application in the AWS Cloud. The application will run on an Amazon EC2 instance. More EC2 instances will be needed when the workload increases.

Which AWS service or tool can the company use to launch the number of EC2 instances that will be needed to handle the workload?

Answer options

• A. Elastic Load Balancing
• B. Amazon EC2 Auto Scaling
• C. AWS App2Container (A2C)
• D. AWS Systems Manager

Correct answer: B

Explanation

Amazon EC2 Auto Scaling is specifically designed to automatically launch or terminate Amazon EC2 instances based on defined policies, schedules, or health checks to handle changing workloads. Elastic Load Balancing only distributes incoming traffic across existing instances, while AWS Systems Manager is used for operational management and AWS App2Container (A2C) is used for containerizing legacy applications.
