Amazon DOP-C02 Exam - Topic 4 Question 23 Discussion

A DevOps engineer manages a web application that runs on Amazon EC2 instances behind an Application Load Balancer (ALB). The instances run in an EC2 Auto Scaling group across multiple Availability Zones. The engineer needs to implement a deployment strategy that:Launches a second fleet of instances with the same capacity as the original fleet.Maintains the original fleet unchanged while the second fleet is launched.Transitions traffic to the second fleet when the second fleet is fully deployed.Terminates the original fleet automatically 1 hour after transition.Which solution will satisfy these requirements?
D) Use AWS Elastic Beanstalk with the configuration set to Immutable. Create an .ebextension using the Resources key that sets the deletion policy of the ALB to 1 hour, and deploy the application.
A) Use an AWS CloudFormation template with a retention policy for the ALB set to 1 hour. Update the Amazon Route 53 record to reflect the new ALB.
B) Use two AWS Elastic Beanstalk environments to perform a blue/green deployment from the original environment to the new one. Create an application version lifecycle policy to terminate the original environment in 1 hour.
C) Use AWS CodeDeploy with a deployment group configured with a blue/green deployment configuration Select the option Terminate the original instances in the deployment group with a waiting period of 1 hour.

Whew, this is a lot to consider. I'm not sure I fully understand the differences between the deployment options like CloudFormation, Elastic Beanstalk, and CodeDeploy. I'll need to review those concepts before attempting this.

Okay, let's see. The key things I need to focus on are launching a second fleet, maintaining the original while the new one is deployed, transitioning traffic, and terminating the original after an hour. I think I can work through this step-by-step.

Option A, huh? Sounds like the DevOps engineer is just winging it and hoping the ALB doesn't pull a disappearing act. Maybe they can summon the AWS gods to keep it alive for that one magical hour.
