Question #: 77
Topic #: 1

[All AWS Certified DevOps Engineer - Professional DOP-C02 Questions]

A DevOps engineer is architecting a continuous development strategy for a company’s software as a service (SaaS) web application running on AWS. For application and security reasons, users subscribing to this application are distributed across multiple Application Load Balancers (ALBs), each of which has a dedicated Auto Scaling group and fleet of Amazon EC2 instances. The application does not require a build stage, and when it is committed to AWS CodeCommit, the application must trigger a simultaneous deployment to all ALBs, Auto Scaling groups, and EC2 fleets.

Which architecture will meet these requirements with the LEAST amount of configuration?

A. Create a single AWS CodePipeline pipeline that deploys the application in parallel using unique AWS CodeDeploy applications and deployment groups created for each ALB-Auto Scaling group pair.
B. Create a single AWS CodePipeline pipeline that deploys the application using a single AWS CodeDeploy application and single deployment group.
C. Create a single AWS CodePipeline pipeline that deploys the application in parallel using a single AWS CodeDeploy application and unique deployment group for each ALB-Auto Scaling group pair.
D. Create an AWS CodePipeline pipeline for each ALB-Auto Scaling group pair that deploys the application using an AWS CodeDeploy application and deployment group created for the same ALB-Auto Scaling group pair.

You can just use one CodeDeploy application and multiple deployment groups in this case. so C.

Selected Answer: C

B. Single deployment group: Won’t support multiple Auto Scaling groups and ALBs unless they’re all in one group, which is not the case here. Cannot handle independent ALB/ASG pairs cleanly. Doesn’t scale well

Selected Answer: C

I was about to vote B since the link from xdkonorek2 shows that one deployment can include up to 10 ELBs. Nevertheless the question says multiple instead of 10.

Selected Answer: C

Option B not feasible as it assumes a single deployment group can manage deployments across multiple ALBs and Auto Scaling groups simultaneously, which is not supported.

Selected Answer: B

B is the simplest :) During creation of deployment group: 1. select "Amazon EC2 Auto Scaling groups" 2. tip appears: "You can select up to 10 Amazon EC2 Auto Scaling groups to deploy your application revision to."

Also B for me, you can target multiple ASGs as part of one deployment: https://docs.aws.amazon.com/codedeploy/latest/APIReference/API_TargetInstances.html#CodeDeploy-Type-TargetInstances-autoScalingGroups

C is correct: <the application must trigger a simultaneous deployment> means deployment in parallel B and D: no mention of deployment in parallel A: <unique AWS CodeDeploy applications and deployment groups created for each ALB-Auto Scaling group pair> means there are multiple AWS CodeDeploy applications and deployment groups for each site, which is unnecessary

Option C deployed in parallel to all ALB-Auto Scaling group pairs simultaneously. This means that the deployment process is efficient and fast, and all ALBs and Auto Scaling groups receive updates at the same time.
