DOP-C01 Free Sample Questions

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 fortesting and production. • Automatic deployment that occurs for test environments only. Which steps should be taken to meet these requirements?

A DevOps Engineer needs to deploy a scalable three-tier Node.js application in AWS. The application must have zero downtime during deployments and be able to roll back to previous versions. Other applications will also connect to the same MySQL backend database. The CIO has provided the following guidance for logging: • Centrally view all current web access server logs. • Search and filter web and application logs in near-real time. • Retain log data for three months. How should these requirements be met?

A company is migrating an application to AWS that runs on a single Amazon EC2 instance. Because of licensing limitations, the application does not support horizontal scaling. The application will be using Amazon Aurora for its database. How can the DevOps Engineer architect automated healing to automatically recover from EC2 and Aurora failures, in addition to recovering across Availability Zones (AZs), in the MOST cost-effective manner?

A company has multiple development teams sharing one AWS account. The development team’s manager wants to be able to automatically stop Amazon EC2 instances and receive notifications if resources are idle and not tagged as production resources. Which solution will meet these requirements?

A company must ensure consistent behavior of an application running on Amazon Linux in its corporate ecosystem before moving into AWS. The company has an existing automated server build system using VMware. The goal is to demonstrate the functionality of the application and its prerequisites on the new target operating system. The DevOps Engineer needs to use the existing corporate server pipeline and virtualization software to create a server image. The server image will be tested on-premises to resemble the build on Amazon EC2 as closely as possible. How can this be accomplished?

A company is using AWS for an application. The Development team must automate its deployments. The team has set up an AWS CodePipeline to deploy the application to Amazon EC2 instances by using AWS CodeDeploy after it has been built using the AWS CodeBuild service. The team would like to add automated testing to the pipeline to confirm that the application is healthy before deploying it to the next stage of the pipeline using the same code. The team requires a manual approval action before the application is deployed, even if the test is successful. The testing and approval must be accomplished at the lowest costs, using the simplest management solution. Which solution will meet these requirements?

A DevOps team wants to implement their containerized application using AWS. The deployment must meet the following requirements: • There should be minimal downtime during deployment. • The application must be functionally tested to be considered a success. How can the DevOps team automate this deployment?

A company has thousands of Amazon EC2 instances as well as hundreds of virtual machines on-premises. Developers routinely sign in to the console for on-premises systems to perform troubleshooting. The Developers want to sign in to AWS instances to run performance tools, but are unable to due to the lack of a central console logging system. A DevOps Engineer wants to ensure that console access is logged on all systems. Which combination of steps will meet these requirements? (Choose two.)

An application is being deployed with two Amazon EC2 Auto Scaling groups, each configured with an Application Load Balancer. The application is deployed to one of the Auto Scaling groups and an Amazon Route 53 alias record is pointed to the Application Load Balancer of the last deployed Auto Scaling group. Deployments alternate between the two Auto Scaling groups. Home security devices are making requests into the application. The Development team notes that new requests are coming into the old stack days after the deployment. The issue is caused by devices that are not observing the Time to Live (TTL) setting on the Amazon Route 53 alias record. What steps should the DevOps Engineer take to address the issue with requests coming to the old stacks, while creating minimal additional resources?

A DevOps Engineer is working on a project that is hosted on Amazon Linux and has failed a security review. The DevOps Manager has been asked to review the company buildspec.yaml file for an AWS CodeBuild project and provide recommendations. The buildspec.yaml file is configured as follows: What changes should be recommended to comply with AWS security best practices? (Choose three.)
