AWS Certified Cloud Practitioner — Question 264

An ecommerce company has deployed a new web application on Amazon EC2 instances. The company wants to distribute incoming HTTP traffic evenly across all running instances.

Which AWS service or resource will meet this requirement?

Answer options

• A. Amazon EC2 Auto Scaling
• B. Application Load Balancer
• C. Gateway Load Balancer
• D. Network Load Balancer

Correct answer: B

Explanation

An Application Load Balancer is the ideal choice because it operates at the application layer (Layer 7) to route and distribute HTTP/HTTPS traffic across Amazon EC2 instances. In contrast, Network Load Balancers are designed for ultra-high performance TCP/UDP traffic at Layer 4, Gateway Load Balancers manage third-party virtual appliances, and Amazon EC2 Auto Scaling adjusts instance capacity rather than routing traffic.
