Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Application Load Balancer
Application Load Balancer (ALB) operates at Layer 7 and can distribute HTTP/HTTPS traffic across multiple web servers, providing health checks and a single DNS name. Option A (Amazon CloudFront) is a content delivery network, not a load balancer. Option B (Network Load Balancer) operates at Layer 4 and is ideal for TCP/UDP traffic, not web application traffic. Option C (Amazon Route 53 weighted routing policy) distributes traffic based on weights but does not provide built-in health checks or load balancing features like connection draining and path-based routing.
