Topic #: 4
[All DOP-C02 Questions]

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?

Option D, eh? Ah, the good old 'set it and forget it' approach. I wonder if the Elastic Beanstalk fairy will just wave her magic wand and make it all work out in the end.

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.

Hold up, Option A with CloudFormation and Route 53 updates? That's like trying to fix a leaky faucet with duct tape and a prayer. Not my cup of tea.

Hmm, Option D with Elastic Beanstalk and the immutable deployment seems interesting. Setting the deletion policy on the ALB is a clever way to handle the termination requirement.

I'm not sure about the other options, but Option C with CodeDeploy and the blue/green configuration sounds pretty solid. Terminating the original instances after 1 hour is a nice touch.

The waiting period of 1 hour before terminating the original instances provides a safety net in case of any issues with the new fleet.

Option B looks like the perfect solution to me. Using Elastic Beanstalk environments for blue/green deployment and a lifecycle policy to handle the original environment termination - that's exactly what the question asks for.

I'm not sure, I think option B could also work. Using Elastic Beanstalk for blue/green deployment with a lifecycle policy to terminate the original environment after 1 hour could be a good approach.
