AWS Certified Cloud Practitioner — Question 716

A company wants to reconfigure its ecommerce application to automatically scale to meet customer demands. The company wants the operating system that the application runs on to be automatically updated.

Which AWS service will meet these requirements?

Answer options

• A. Amazon Lightsail
• B. Amazon EC2
• C. AWS Lambda
• D. Amazon EC2 Auto Scaling

Correct answer: D

Explanation

Amazon EC2 Auto Scaling allows applications to dynamically scale capacity up or down to meet fluctuating user demands. By utilizing launch templates that reference the latest Amazon Machine Images (AMIs), the underlying operating system can be automatically updated as new instances are provisioned. Other services like basic Amazon EC2 or Amazon Lightsail do not natively provide this automated scaling and updating combination.
