AWS-Certified-DevOps-Engineer-Professional Free Practice Test

A DevOps Engineer at a startup cloud-based gaming company has the task formalizing deployment strategies. The strategies must meet the following requirements:
Use standard Git commands, such as git clone and git push for the code repository. Management tools should maximize the use of platform solutions where possible. Deployment packages must be immutable and in the form of Docker images.

7. G. CodePipeline will deploy into a second target group in Amazon ECS behind an Application Load Balance
8. H. Cutover will be managed by swapping the listener rules on the Application Load Balancer.
9. I. Use a Jenkins pipeline to trigger a build process when software is pushed to a private GitHub repository.AWS CodePipeline will use AWS CodeBuild new Docker image
10. J. CodePipeline will deploy into a second target group in Amazon ECS behind an Application Load Balance
11. K. Cutover will be managed by swapping the listener rules on the Application Load Balancer.
12. L. Use AWS CodePipeline to trigger a build process when software is pushed to an AWS CodeCommit repository CodePipeline will use an AWS CodeBuild build server to build new Docker image
13. M. CodePipeline will deploy into a second target group in a Kubernetes Cluster hosted on Amazon EC2 behind an Application Load Balance
14. N. Cutover will be managed by swapping the listener rules on the Application Load Balancer.

Correct Answer: B

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?

1. A. Deploy the application on an Amazon EC2 instance and create an AMI of this instanc
2. B. Use this AMI to create an automatic scaling launch configuration that is used in an Auto Scaling grou
3. C. Use an Elastic Load Balancer to distribute traffi
4. D. When changes are made to the application, a new AMI is created and replaces the launch configuration.
5. E. Use Amazon Lightsail to deploy the applicatio
6. F. Store the application in a zipped format in an Amazon S3 bucket Use this zipped version to deploy new versions of the application to Lightsai
7. G. Use Lightsail deployment options to manage the deployment.
8. H. Use AWS CodePipeline with AWS CodeDeploy to deploy the application to a fleet of Amazon EC2 instance
9. I. Use an Elastic Load Balancer to distribute the traffic to the EC2 instance
10. J. When making changes to the application, upload a new version to CodePipeline and let it deploy the new version.
11. K. Use AWS Elastic Beanstalk to host the applicatio
12. L. Store a zipped version of the application in AmazonS3, and use that location to deploy new versions of the application using Elastic Beanstalk to manage the deployment options.

Correct Answer: D

An n-tier application requires a table in an Amazon RDS MySQL DB instance to be dropped and repopulated at each deployment. This process can take several minutes and the web tier cannot come online until the process is complete. Currently, the web tier is configured in an Amazon EC2 Auto Scaling group, with instances being terminated and replaced at each deployment. The MySQL table
is populated by running a SQL query through an AWS CodeBuild job.
What should be done to ensure that the web tier does not come online before the database is completely configured?

1. A. Use Amazon Aurora as a drop-in replacement for RDS MySQ
2. B. Use snapshots to populate the table with the correct data.
3. C. Modify the launch configuration of the Auto Scaling group to pause user data execution for 600 seconds, allowing the table to be populated.
4. D. Use AWS Step Functions to monitor and maintain the state of data populatio
5. E. Mark the database in service before continuing with the deployment.
6. F. Use an EC2 Auto Scaling lifecycle hook to pause the configuration of the web tier until the table is populated.

Correct Answer: D

The management team at a company with a large on-premises OpenStack environment wants to move non-production workloads to AWS. An AWS Direct Connect connection has been provisioned and configured to connect the environments. Due to contractual obligations, the production workloads must remain on- premises, and will be moved to AWS after the next contract negotiation. The company follows Center for Internet Security (CIS) standards for hardening images; this configuration was developed using the company's configuration management system.
Which solution will automatically create an identical image in the AWS environment without significant overhead?

1. A. Write an AWS CloudFormation template that will create an Amazon EC2 instanc
2. B. Use cloud-unit to install the configuration management agent, use cfn-wait to wait for configuration management to successfully apply, and use an AWS Lambda-backed custom resource to create the AMI.
3. C. Log in to the console, launch an Amazon EC2 instance, and install the configuration management agent.When changes are applied through the configuration management system, log in to the console and create a new AMI from the instance.
4. D. Create a new AWS OpsWorks layer and mirror the image hardening standard
5. E. Use this layer as the baseline for all AWS workloads.
6. F. When a change is made in the configuration management system, a job in Jenkins is triggered to use the VM Import command to create an Amazon EC2 instance in the Amazon VP
7. G. Use lifecycle hooks to launch an AWS Lambda function to create the AMI.

A DevOps engineer is currently running a container-based workload on-premises The engineer wants to move the application to AWS, but needs to keep the on-premises solution active because not all APIs will move at the same time. The traffic between AWS and the on-premises network should be secure and encrypted at all times. Low management overload is also a requirement.
Which combination of actions will meet these criteria? (Select THREE.)

1. A. Create a Network Load Balancer an
2. B. for each service, create a listener that points to the correct set of containers either in AWS or on-premises.
3. C. Create an Application Load Balancer and, for each service, create a listener that points to the correct set of containers either in AWS or on-premises.
4. D. Host the AWS containers in Amazon ECS with an EC2 launch type.
5. E. Host the AWS containers in Amazon ECS with a Fargate launch type
6. F. Use Amazon API Gateway to front the workload, and create a VPC link so API Gateway can forward API calls to the on-premises network through a VPN connection.
7. G. Use Amazon API Gateway to front the workload, and set up public endpoints for the on-premises APIs so API Gateway can access them.
