AWS Certified Solutions Architect - Associate SAA-C03 — Topic 1 Question 264

Question

A company has a web application hosted over 10 Amazon EC2 instances with traffic directed by Amazon Route 53. The company occasionally experiences a timeout error when attempting to browse the application. The networking team finds that some DNS queries return IP addresses of unhealthy instances, resulting in the timeout error. What should a solutions architect implement to overcome these timeout errors?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Create an Application Load Balancer (ALB) with a health check in front of the EC2 instances. Route to the ALB from Route 53. Amazon EC2 provides resizable virtual servers when you need full control of the operating system. Amazon Route 53 provides DNS with health checks and routing policies for availability and latency. An Application Load Balancer distributes HTTP/HTTPS traffic and supports path/host routing.
