Question 35

A company has developed a static website hosted on an Amazon S3 bucket. The website is deployed using AWS CloudFormation. The CloudFormation template defines an S3 bucket and a custom resource that copies content into the bucket from a source location.The company has decided that it needs to move the website to a new location, so the existing CloudFormation stack must be deleted and re-created. However, CloudFormation reports that the stack could not be deleted cleanly.What is the MOST likely cause and how can the DevOps engineer mitigate this problem for this and future versions of the website?

Accepted Answer

Deletion has failed because the S3 bucket is not empty. Modify the custom resource's AWS Lambda function code to recursively empty the bucket when RequestType is Delete.

Question 40

A company is using AWS CodeDeploy to automate software deployment. The deployment must meet these requirements:* A number of instances must be available to serve traffic during the deployment Traffic must be balanced across those instances, and the instances must automatically heal in the event of failure.* A new fleet of instances must be launched for deploying a new revision automatically, with no manual provisioning.* Traffic must be rerouted to the new environment to half of the new instances at a time. The deployment should succeed if traffic is rerouted to at least half of the instances; otherwise, it should fail.* Before routing traffic to the new fleet of instances, the temporary files generated during the deployment process must be deleted.* At the end of a successful deployment, the original instances in the deployment group must be deleted immediately to reduce costs.How can a DevOps engineer meet these requirements?
