AWS Certified DevOps Engineer - Professional DOP-C02 — Topic 1 Question 226

Question

A company is using AWS CodeDeploy to automate software deployment. The deployment must meet these requirements: • A number of instances must be available to serve traffic during the deployment. Traffic must be balanced across those instances, and the instances must automatically heal in the event of failure. • A new fleet of instances must be launched for deploying a new revision automatically, with no manual provisioning. • Traffic must be rerouted to the new environment to half of the new instances at a time. The deployment should succeed if traffic is rerouted to at least half of the instances: otherwise, it should fail. • Before routing traffic to the new fleet of instances, the temporary files generated during the deployment process must be deleted. • At the end of a successful deployment, the original instances in the deployment group must be deleted immediately to reduce costs. How can a DevOps engineer meet these requirements?

Accepted Answer

Correct answer: C. The correct answer is C. Option C: Use an Application Load Balancer and a blue/green deployment. Associate the Auto Scaling group and the Application Load Balancer target group with the deployment group. Use the Automatically copy Auto Scaling group op... Auto Scaling adjusts capacity automatically to match demand, improving availability and cost efficiency. 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. This option delivers the requirement at the lowest cost.
