AWS Certified Cloud Practitioner (CLF-C02) — Question 618

What is a benefit of using an Elastic Load Balancing (ELB) load balancer with applications running in the AWS Cloud?

Answer options

• A. An ELB will automatically scale resources to meet capacity needs.
• B. An ELB can balance traffic across multiple compute resources.
• C. An ELB can span multiple AWS Regions.
• D. An ELB can balance traffic between multiple internet gateways.

Correct answer: B

Explanation

Elastic Load Balancing (ELB) is designed to distribute incoming application or network traffic across multiple targets, such as Amazon EC2 instances, containers, and IP addresses, ensuring high availability. It does not automatically scale the backend compute resources themselves (which is handled by Auto Scaling), nor does it natively span multiple AWS Regions or route traffic between internet gateways.
