AWS Certified DevOps Engineer - Professional DOP-C02 — Topic 1 Question 383

Question

A company is migrating its web application to AWS. The application uses WebSocket connections for real-time updates and requires sticky sessions. A DevOps engineer must implement a highly available architecture for the application. The application must be accessible to users worldwide with the least possible latency. Which solution will meet these requirements with the LEAST operational overhead?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Deploy an Application Load Balancer (ALB). Deploy another ALB in a different AWS Region. Enable cross-zone load balancing and sticky sessions on the ALBs. Integrate the ALBs with Amazon Route 53 latency-based routing. 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. A load balancer distributes traffic across targets in multiple AZs for availability and scale.
