AWS Certified Cloud Practitioner — Question 603

A company wants to build a new web application by using AWS services. The application must meet the on-demand load for periods of heavy activity.

Which AWS services or resources provide the necessary workload adjustments to meet these requirements? (Choose two.)

Answer options

• A. Amazon Machine Image (AMI)
• B. Amazon EC2 Auto Scaling
• C. Amazon EC2 instance
• D. AWS Lambda
• E. EC2 Image Builder

Correct answer: B, D

Explanation

Amazon EC2 Auto Scaling automatically adjusts the number of EC2 instances up or down to match the application's demand during peak periods. AWS Lambda is a serverless service that inherently scales automatically by running code in response to each trigger, making both ideal for handling dynamic workloads. Other options like AMIs, individual EC2 instances, and EC2 Image Builder do not provide automated, dynamic scaling capabilities.
