AWS Certified Solutions Architect - Associate SAA-C03 — Topic 1 Question 246

Question

A company runs a web application on Amazon EC2 instances in multiple Availability Zones. The EC2 instances are in private subnets. A solutions architect implements an internet-facing Application Load Balancer (ALB) and specifies the EC2 instances as the target group. However, the internet traffic is not reaching the EC2 instances. How should the solutions architect reconfigure the architecture to resolve this issue?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Create public subnets in each Availability Zone. Associate the public subnets with the ALB. Update the route tables for the public subnets with a route to the private subnets. By spanning multiple Availability Zones / adding redundancy, this option provides the high availability and resilience required.
