Question 1

An American tech company used an AWS CloudFormation template to deploy its static corporate website hosted on Amazon S3 in the US East (N. Virginia) region. The template defines an Amazon S3 bucket with a Lambda-backed custom resource that downloads the content from a file server into the bucket. There is a new task for the DevOps Engineer to move the website to the US West (Oregon) region to better serve its customers on the West Coast with lower latency. However, the application stack could not be deleted successfully in CloudFormation.

Which among the following options shows the root cause of this issue, and how can the DevOps Engineer mitigate this problem for current and future versions of the website?

A : CloudFormation stack deletion fails for an S3 bucket that is used as a static web hosting. To fix the issue, modify the CloudFormation template to remove the website configuration for the S3 bucket.

B : CloudFormation stack deletion fails for an S3 bucket because the DeletionPolicy attribute is set to Snapshot. To fix the issue, set the DeletionPolicy to Delete instead.

C : CloudFormation stack deletion fails for an S3 bucket that still has contents. To fix the issue, modify the Lambda function code of the custom resource to recursively empty the bucket if the stack is selected for deletion.

D : CloudFormation stack deletion fails for an S3 bucket because it is not yet empty. To fix the issue, set the DeletionPolicy to ForceDelete instead.

Answer: C

Question 2

A DevOps engineer needs to configure an AWS CodePipeline pipeline that publishes container images to an Amazon ECR repository. The pipeline must wait for the previous run to finish and must run when new Git tags are pushed to a Git repository connected to AWS CodeConnections. An existing deployment pipeline must run in response to new container image publications. Which solution will meet these requirements?

A : Configure a CodePipeline V2 type pipeline that uses QUEUED mode. Add a trigger filter to the pipeline definition that includes all tags. Configure an EventBridge rule that matches container image pushes to start the existing deployment pipeline.

B : Configure a CodePipeline V2 type pipeline that uses SUPERSEDED mode. Add a trigger filter to the pipeline definition that includes all branches. Configure an EventBridge rule that matches container image pushes to start the existing deployment pipeline.

C : Configure a CodePipeline V1 type pipeline that uses SUPERSEDED mode. Add a trigger filter to the pipeline definition that includes all tags. Add a stage at the end of the pipeline to invoke the existing deployment pipeline.

D : Configure a CodePipeline V1 type pipeline that uses QUEUED mode. Add a trigger filter to the pipeline definition that includes all branches. Add a stage at the end of the pipeline to invoke the existing deployment pipeline.

Answer: A

Question 3

A development team manually builds a local artifact. The development team moves the artifact to an Amazon S3 bucket to support an application. The application has a local cache that must be cleared when the development team deploys the application to Amazon EC2 instances. For each deployment, the development team runs a command to clear the cache, download the artifact from the S3 bucket, and unzip the artifact to complete the deployment. The development team wants to migrate the deployment process to a CI/CD process and to track the progress of each deployment. Which combination of actions will meet these requirements with the MOST operational efficiency? (Select THREE.)

A : Set up an AWS CodeConnections compatible Git repository. Allow developers to merge code into the repository. Use AWS CodeBuild to build an artifact and copy the object into the S3 bucket. Configure CodeBuild to run for every merge into the main branch.

B : Create a custom script to clear the cache. Specify the script in the BeforeInstall lifecycle hook in the AppSpec file.

C : Create user data for each EC2 instance that contains the cache clearing script. Test the application after deployment. If the deployment is not successful, then redeploy.

D : Use AWS CodePipeline to deploy the application. Set up an AWS CodeConnections compatible Git repository. Allow developers to merge code into the repository as a source for the pipeline.

E : Use AWS CodeBuild to build the artifact and place the artifact in the S3 bucket. Use AWS CodeDeploy to deploy the artifact to EC2 instances.

F : Use AWS Systems Manager to fetch the artifact from the S3 bucket and to deploy the artifact to all the EC2 instances.

Answer: B,D,E

Question 4

A company is building a web and mobile application that uses a serverless architecture powered by AWS Lambda and Amazon API Gateway. The company wants to fully automate the backend Lambda deployment based on code that is pushed to the appropriate environment branch in an AWS CodeCommit repository.

The deployment must have the following:

• Separate environment pipelines for testing and production

• Automatic deployment that occurs for test environments only

Which steps should be taken to meet these requirements?

A : Configure a new AWS CodePipeline service. Create a CodeCommit repository for each environment. Set up CodePipeline to retrieve the source code from the appropriate repository. Set up the deployment step to deploy the Lambda functions with AWS CloudFormation.

B : Create two AWS CodePipeline configurations for test and production environments. Configure the production pipeline to have a manual approval step. Create a CodeCommit repository for each environment. Set up each CodePipeline to retrieve the source code from the appropriate repository. Set up the deployment step to deploy the Lambda functions with AWS CloudFormation.

C : Create two AWS CodePipeline configurations for test and production environments. Configure the production pipeline to have a manual approval step. Create one CodeCommit repository with a branch for each environment. Set up each CodePipeline to retrieve the source code from the appropriate branch in the repository. Set up the deployment step to deploy the Lambda functions with AWS CloudFormation

D : Create an AWS CodeBuild configuration for test and production environments. Configure the production pipeline to have a manual approval step. Create one CodeCommit repository with a branch for each environment. Push the Lambda function code to an Amazon S3 bucket. Set up the deployment step to deploy the Lambda functions from the S3 bucket.

Answer: C

Question 5

A company has several AWS accounts. An Amazon Connect instance runs in each account. The company uses an Amazon EventBridge default event bus in each account for event handling. A DevOps team needs to receive all the Amazon Connect events in a single DevOps account. Which solution meets these requirements?

A : Update the resource-based policy of the default event bus in each account to allow the DevOps account to replay events. Configure an EventBridge rule in the DevOps account that matches Amazon Connect events and has a target of the default event bus in the other accounts.

B : Update the resource-based policy of the default event bus in each account to allow the DevOps account to receive events. Configure an EventBridge rule in the DevOps account that matches Amazon Connect events and has a target of the default event bus in the other accounts.

C : Update the resource-based policy of the default event bus in the DevOps account. Update the policy to allow events to be received from the accounts. Configure an EventBridge rule in each account that matches Amazon Connect events and has a target of the DevOps account's default event bus

D : Update the resource-based policy of the default event bus in the DevOps account. Update the policy to allow events to be replayed by the accounts. Configure an EventBridge rule in each account that matches Amazon Connect events and has a target of the DevOps account's default event bus.

Answer: C
