AWS Certified DevOps Engineer - Professional Questions and Answers

Question 1

A development team manually builds an artifact locally and then places it in an Amazon S3 bucket. The application has a local cache that must be cleared when a deployment occurs. The team runs a command to do this downloads the artifact from Amazon S3 and unzips the artifact to complete the deployment.

A DevOps team wants to migrate to a CI/CD process and build in checks to stop and roll back the deployment when a failure occurs. This requires the team to track the progression of the deployment.

Which combination of actions will accomplish this? (Select THREE)

Options:

A.

Allow developers to check the code into a code repository Using Amazon EventBridge on every pull into the mam branch invoke an AWS Lambda function to build the artifact and store it in Amazon S3.

B.

Create a custom script to clear the cache Specify the script in the Beforelnstall lifecycle hook in the AppSpec file.

C.

Create user data for each Amazon EC2 instance that contains the clear cache script Once deployed test the application If it is not successful deploy it again.

D.

Set up AWS CodePipeline to deploy the application Allow developers to check the code into a code repository as a source tor the pipeline.

E.

Use AWS CodeBuild to build the artifact and place it in Amazon S3 Use AWS CodeDeploy to deploy the artifact to Amazon EC2 instances.

F.

Use AWS Systems Manager to fetch the artifact from Amazon S3 and deploy it to all the instances.

Question 2

A company that uses electronic patient health records runs a fleet of Amazon EC2 instances with an Amazon Linux operating system. The company must continuously ensure that the EC2 instances are running operating system patches and application patches that are in compliance with current privacy regulations. The company uses a custom repository to store application patches.

A DevOps engineer needs to automate the deployment of operating system patches and application patches. The DevOps engineer wants to use both the default operating system patch repository and the custom patch repository.

Which solution will meet these requirements with the LEAST effort?

Options:

A.

Use AWS Systems Manager to create a new custom patch baseline that includes the default operating system repository and the custom repository. Run the AWS-RunPatchBaseline document by using the Run command to verify and install patches. Use the BaselineOverride API to configure the new custom patch baseline.

B.

Use AWS Direct Connect to integrate the custom repository with the EC2 instances. Use Amazon EventBridge events to deploy the patches.

C.

Use the yum-config-manager command to add the custom repository to the /etc/yum.repos.d configuration. Run the yum-config-manager-enable command to activate the new repository.

D.

Use AWS Systems Manager to create a patch baseline for the default operating system repository and a second patch baseline for the custom repository. Run the AWS-RunPatchBaseline document by using the Run command to verify and install patches. Use the BaselineOverride API to configure the default patch baseline and the custom patch baseline.

Question 3

A company runs an application on an Amazon Elastic Kubernetes Service (Amazon EKS) cluster in the company ' s primary AWS Region and secondary Region. The company uses Auto Scaling groups to distribute each EKS cluster’s worker nodes across multiple Availability Zones. Both EKS clusters also have an Application Load Balancer (ALB) to distribute incoming traffic.

The company wants to deploy a new stateless application to its infrastructure. The company requires a multi-Region, fault tolerant solution.

Which solution will meet these requirements?

Options:

A.

Deploy the new application to both EKS clusters. Create Amazon Route 53 records with health checks for both ALBs. Use a failover routing policy. Implement Kubernetes readiness and liveness probes.

B.

Deploy the new application to the EKS cluster in the primary Region. Create Amazon Route 53 records with health checks for the primary Region ALB. Use a simple routing policy.

C.

Deploy the new application to both EKS clusters. Create Amazon Route 53 records with a weighted routing policy that evenly splits traffic between both ALBs. Implement Kubernetes readiness and liveness probes.

D.

Deploy the new application to the EKS cluster in the primary Region. Create Amazon Route 53 records with health checks for the primary Region ALB. Use a failover routing policy.
