ANS-C01 Network Implementation Practice Question
A company is deploying a new web application on AWS. They need to distribute incoming HTTPS traffic across multiple EC2 instances in different Availability Zones. Which AWS service should they use?
⚠ Common exam trap
Many exam-takers confuse Layer 4 (NLB) with Layer 7 (ALB) and incorrectly choose NLB because it handles high throughput, but they miss that HTTPS requires application-layer inspection and TLS termination, which only ALB provides natively.
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 (ALB)
The Application Load Balancer (ALB) is the correct choice because it operates at Layer 7 (HTTP/HTTPS) and can terminate TLS, inspect HTTPS headers, and route traffic based on content. It is designed to distribute incoming HTTPS traffic across multiple EC2 instances in different Availability Zones, providing health checks and automatic scaling.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Amazon Route 53
Why it's wrong here
Route 53 is a DNS service that can route traffic but not load-balance at the application layer.
- ✗
Amazon CloudFront
Why it's wrong here
CloudFront is a content delivery network, not a regional load balancer.
- ✓
Application Load Balancer (ALB)
Why this is correct
ALB operates at Layer 7, can terminate HTTPS, and distribute traffic across instances in multiple AZs.
- ✗
Network Load Balancer (NLB)
Why it's wrong here
NLB operates at Layer 4 and cannot terminate HTTPS or perform content-based routing.
