Amazon Exam DOP-C02 Topic 8 Question 33 Discussion

Actual exam question for Amazon's DOP-C02 exam

Question #: 33
Topic #: 8

A DevOps engineer is setting up an Amazon Elastic Container Service (Amazon ECS) blue/green deployment for an application by using AWS CodeDeploy and AWS CloudFormation. During the deployment window, the application must be highly available and CodeDeploy must shift 10% of traffic to a new version of the application every minute until all traffic is shifted.

Which configuration should the DevOps engineer add in the CloudFormation template to meet these requirements?

AAdd an AppSpec file with the CodeDeployDefault.ECSLineaMOPercentEverylMinutes deployment configuration.

BAdd the AWS::CodeDeployBlueGreen transform and the AWS::CodeDeploy::BlueGreen hook parameter with the CodeDeployDefault.ECSLinear10PercentEvery1 Minutes deployment configuration.

CAdd an AppSpec file with the ECSCanary10Percent5Minutes deployment configuration.

DAdd the AWS::CodeDeployBlueGroen transform and the AWS::CodeDeploy::BlueGreen hook parameter with the ECSCanary10Percent5Minutes deployment configuration.
Step 1: Using AWS CloudFormation with ECS Blue/Green Deployments
The requirement is to implement an ECS blue/green deployment where traffic is shifted gradually. AWS CodeDeploy supports such blue/green deployments with predefined configurations, like ECSLinear10PercentEvery1Minute, which shifts 10% of traffic every minute.
Action: Use the AWS::CodeDeployBlueGreen transform and the appropriate hooks in the CloudFormation template. The ECSLinear10PercentEvery1Minute deployment configuration meets the requirement of shifting 10% of traffic every minute.
Why: The transform and hook parameters in CloudFormation are essential for configuring the blue/green deployment with the desired traffic-shifting behavior.

Show Suggested Answer

Suggested Answer: B

This corresponds to Option B: Add the AWS::CodeDeployBlueGreen transform and the AWS::CodeDeploy::BlueGreen hook parameter with the CodeDeployDefault.ECSLinear10PercentEvery1Minutes deployment configuration.

Hmm, I wonder if the DevOps engineer is feeling a bit 'blue' about this deployment. Get it? 'Blue/green' deployment? I'll see myself out.

I'm not sure about this 'ECSCanary' thing. Sounds like a new exotic bird. I'd go with Option B if I were you.

I'm not sure, but it makes sense to gradually shift the traffic during deployment to ensure high availability. So, I think B is the correct answer.

Hold up, I think Option C might be a better fit. The ECSCanary10Percent5Minutes configuration seems to match the requirement more closely.

Shawnda, I see your point, but the ECSLinear10PercentEvery1Minute configuration in Option B aligns better with the requirement for shifting 10% of traffic every minute.
