Question 1

An application's users ate encountering bugs immediately after Amazon API Gateway deployments. The development team deploys once or twice a day and uses a blue/green deployment strategy with custom health checks and automated rollbacks. The team wants to limit the number of users affected by deployment bugs and receive notifications when rollbacks are needed.

Which combination of steps should a DevOps engineer use to meet these requests? (Select TWO.)

AImplement a blue/green strategy using path mappings.

BImplement a canary deployment strategy.

CImplement a rolling deployment strategy using multiple stages.

DUse Amazon CloudWatch alarms to notify the development team.

EUse Amazon CloudWatch Events to notify the development team.

Answer : B, D

Question 2

A DevOps engineer is tasked with moving a mission-critical business application running in Go to AWS. The development team running this application is understaffed and requires a solution that allows the team to focus on application development. They also want to enable blue/green deployments and perform A/B testing.

Which solution will meet these requirements?

ADeploy the application on an Amazon EC2 instance and create an AMI of this instance. Use this AMI to create an automatic scaling launch configuration that is used in an Auto Scaling group. Use an Elastic Load Balancer to distribute traffic. When changes are made to the application, a new AMI is created and replaces the launch configuration.

BUse Amazon Lightsail to deploy the application. Store the application in a zipped format in an Amazon S3 bucket Use this zipped version to deploy new versions of the application to Lightsail. Use Lightsail deployment options to manage the deployment.

CUse AWS CodePipeline with AWS CodeDeploy to deploy the application to a fleet of Amazon EC2 instances. Use an Elastic Load Balancer to distribute the traffic to the EC2 instances. When making changes to the application, upload a new version to CodePipeline and let it deploy the new version.

DUse AWS Elastic Beanstalk to host the application. Store a zipped version of the application in Amazon S3, and use that location to deploy new versions of the application using Elastic Beanstalk to manage the deployment options.

Answer : D

Question 3

A company wants to use AWS Systems Manager documents to bootstrap physical laptops for developers. The bootstrap code is stored in GitHub. A DevOps engineer has already created a Systems Manager activation, installed the Systems Manager agent with the registration code, and installed an activation ID on all the laptops.

Which set of steps should be taken next?

AConfigure the Systems Manager document to use the AWS-RunShellScript command to copy the files from GitHub to Amazon S3, then use the aws-downloadContent plugin with a source Type of S3.

BConfigure the Systems Manager document to use the aws-configurePackage plugin with an install action and point to the Git repository.

CConfigure the Systems Manager document to use the aws-downloadContent plugin with a sourceType of GitHub and sourcelnfo with the repository details.

DConfigure the Systems Manager document to use the aws:softwarelnventory plugin and run the script from the Git repository.

Answer : D

Question 4

A company needs to implement a robust CI/CD pipeline to automate the deployment of an application in AWS. The pipeline must support continuous integration, continuous delivery, and automatic rollback upon deployment failure. The entire CI/CD pipeline must be capable of being re-provisioned in alternate AWS accounts or Regions within minutes. A DevOps engineer has already created an AWS CodeCommit repository to store the source code.

Which combination of actions should be taken when building this pipeline to meet these requirements? (Select THREE.)

AConfigure an AWS CodePipehne pipeline with a build stage using AWS CodeBuild.

BCopy the build artifact from CodeCommit to Amazon S3.

CCreate an Auto Scaling group of Amazon EC2 instances behind an Application Load Balancer (ALB) and set the ALB as the deployment target in AWS CodePipeline.

DCreate an AWS Elastic Beanstalk environment as the deployment target in AWS CodePipeline.

EImplement an Amazon SQS queue to decouple the pipeline components.

FProvision all resources using AWS CloudFormation.

Answer : A, B, D

Question 5

A development team wants to deploy an application using AWS CloudFormation stacks, but the developer IAM role does not currently have the required permissions to provision the resources specified in the CloudFormation template. A DevOps engineer is tasked with allowing developers to deploy the stacks while following the principal of least privilege.

Which solution will meet these requirements?

ACreate an IAM policy that allows developers to provision the required resources. Attach the policy to the developer role.

BCreate an IAM policy that allows full access to CloudFormation. Attach the policy to the developer role.

CCreate a new IAM role with the required permissions to use as a CloudFormation service role. Grant the developer role a cloudformation:* action.

DCreate a new IAM role with the required permissions to use as a CloudFormation service role. Grant the developer role the iam:PassRole permission.

Answer : C

Question 6

A company has containerized all of its in-house quality control applications. The company is running Jenkins on Amazon EC2. which requires patching and upgrading. The compliance officer has requested a DevOps engineer begin encrypting build artifacts since they contain company intellectual property.

What should the DevOps engineer do to accomplish this in the MOST maintainable manner?

AAutomate patching and upgrading using AWS Systems Manager on EC2 instances and encrypt Amazon EBS volumes by default.

BDeploy Jenkins to an Amazon ECS cluster and copy build artifacts to an Amazon S3 bucket with default encryption enabled.

CLeverage AWS CodePipeline with a build action and encrypt the artifacts using AWS Secrets Manager.

DUse AWS CodeBuild with artifact encryption to replace the Jenkins instance running on Amazon EC2.

Answer : D

Question 7

A DevOps engineer is researching the least expensive way to implement an image batch processing cluster on AWS. The application cannot run in Docker containers and must run on Amazon EC2. The batch job stores checkpoint data on an NFS and can tolerate interruptions. Configuring the cluster software from a generic EC2 Linux image takes 30 minutes.

What is the MOST cost-effective solution?

AUse Amazon EFS for checkpoint data. To complete the job. use an EC2 Auto Scaling group and an On-Demand pricing model to provision EC2 instances temporarily.

BUse GlusterFS on EC2 instances for checkpoint data. To run the batch job. configure EC2 instances manually. When the job completes, shut down the instances manually.

CUse Amazon EFS for checkpoint data. Use EC2 Fleet to launch EC2 Spot Instances, and utilize user data to configure the EC2 Linux instance on startup.

DUse Amazon EFS for checkpoint data. Use EC2 Fleet to launch EC2 Spot Instances. Create a custom AMI for the cluster and use the latest AMI when creating instances.
