Exam question from Amazon's AWS Certified Solutions Architect - Professional

Question #: 566
Topic #: 1

[All AWS Certified Solutions Architect - Professional Questions]

A company's CISO has asked a Solutions Architect to re-engineer the company's current CI/CD practices to make sure patch deployments to its applications can happen as quickly as possible with minimal downtime if vulnerabilities are discovered. The company must also be able to quickly roll back a change in case of errors.
The web application is deployed in a fleet of Amazon EC2 instances behind an Application Load Balancer. The company is currently using GitHub to host the application source code, and has configured an AWS CodeBuild project to build the application. The company also intends to use AWS CodePipeline to trigger builds from GitHub commits using the existing CodeBuild project.
What CI/CD configuration meets all of the requirements?

A. Configure CodePipeline with a deploy stage using AWS CodeDeploy configured for in-place deployment. Monitor the newly deployed code, and, if there are any issues, push another code update.
B. Configure CodePipeline with a deploy stage using AWS CodeDeploy configured for blue/green deployments. Monitor the newly deployed code, and, if there are any issues, trigger a manual rollback using CodeDeploy.
C. Configure CodePipeline with a deploy stage using AWS CloudFormation to create a pipeline for test and production stacks. Monitor the newly deployed code, and, if there are any issues, push another code update.
D. Configure the CodePipeline with a deploy stage using AWS OpsWorks and in-place deployments. Monitor the newly deployed code, and, if there are any issues, push another code update.

B seems about right: blue/green deployments to minimize downtime (as opposed to in-place deployments) + deployments can be rolled back automatically or manually with CodeDeploy. https://docs.aws.amazon.com/codedeploy/latest/userguide/deployments.html

Ans: A Since the requirement is "as quickly as possible with minimal downtime". Blue/green is not as quick and the question didn't ask for zero downtime.

Your missing the point of the question "push another code update." is NOT a ROLLBACK .... Its important to READ the question in the exam ... B is right as it is very fluid ..

B. Configure CodePipeline with a deploy stage using AWS CodeDeploy configured for blue/green deployments. Monitor the newly deployed code, and, if there are any issues, trigger a manual rollback using CodeDeploy.
