20. A company wants to implement a continuous integration for its workloads on AWS. The company wants to trigger unit test in its pipeline for commits-on its code repository, and wants to be notified of failure events in the pipeline.
How can these requirements be met? Store the source code in AWS CodeCommit. Create a CodePipeline to automate unit testing. Use Amazon SNS to trigger notifications of failure events. Store the source code in GitHub. Create a CodePipeline to automate unit testing. Use Amazon SES to trigger notifications of failure events. Store the source code on GitHub. Create a CodePipeline to automate unit testing. Use Amazon CloudWatch to trigger notifications of failure events. Store the source code in AWS CodeCommit. Create a CodePipeline to automate unit testing. Use Amazon CloudWatch to trigger notification of failure events. 46. For a deployment using AWS CodeDeploy, what is the run order of the hooks for in-place deployments? Before Install -> Application Stop -> Application Start -> After Install Application Stop -> Before Install -> After Install -> Application Start Before Install -> Application Stop -> Validate Service -> Application Start Application Stop -> Before Install -> Validate Service -> Application Start. 53. A company is using AWS CodeBuild to compile a website from source code stored in AWS CodeCommit. A recent change to the source code has resulted in the CodeBuild project being unable to successfully compile the website.
How should the Developer identify the cause of the failures? Modify the buildspec.yml file to include steps to send the output of build commands to Amazon CloudWatch. Use a custom Docker image that includes the AWS X-Ray agent in the AWS CodeBuild project configuration. Check the build logs of the failed phase in the last build attempt in the AWS CodeBuild project build history. Manually re-run the build process on a local machine so that the output can be visualized. 62. The release process workflow of an application requires a manual approval before the code is deployed into the production environment.
What is the BEST way to achieve this using AWS CodePipeline? Use multiple pipelines to allow approval Use an approval action in a stage Disable the stage transition to allow manual approval Disable a stage just prior the deployment stage. 63. Where should the appspec.yml file be placed in order for AWS CodeDeploy to work? In the root of the application source code directory structure. In the bin folder along with all the complied code. In an S3 bucket. In the same folder as the application configuration files. 74. When a Developer tries to run an AWS CodeBuild project, it raises an error because the length of all environment variables exceeds the limit for the combined maximum of characters.
What is the recommended solution? Add the export LC_ALL="en_US.utf8" command to the pre_build section to ensure POSIX localization. Use Amazon Cognito to store key-value pairs for large numbers of environment variables. Update the settings for the build project to use an Amazon S3 bucket for large numbers of environment variables. Use AWS Systems Manager Parameter Store to store large numbers of environment variables. 76. The Developer for a retail company must integrate a fraud detection solution into the order processing solution. The fraud detection solution takes between ten and thirty minutes to verify an order. At peak, the web site can receive one hundred orders per minute.
What is the most scalable method to add the fraud detection solution to the order processing pipeline? Add all new orders to an Amazon SQS queue. Configure a fleet of 10 EC2 instances spanning multiple AZs with the fraud detection solution installed on them to pull orders from this queue. Update the order with a pass or fails status. Add all new orders to an SQS queue. Configure an Auto Scaling group that uses the queue depth metric as its unit of scale to launch a dynamically-sized fleet of EC2 instances spanning multiple AZs with the fraud detection solution installed on them to pull orders from this queue. Update the order with a pass or fails status. Add all new orders to an Amazon Kinesis Stream. Subscribe a Lambda function to automatically read batches of records from the Kinesis Stream. The Lambda function includes the fraud detection software and will update the order with a pass or fail status. Write all new orders to Amazon DynamoDB. Configure DynamoDB Streams to include all new orders. Subscribe a Lambda function to automatically read batches of records from the Kinesis Stream. The Lambda function includes the fraud detection software and will update the order with a pass or fail status. 87. A company is using AWS CodePipeline to deliver one of its applications. The delivery pipeline is triggered by changes to the master branch of an AWSCodeCommit repository and uses AWS CodeBuild to implement the test and build stages of the process and AWS CodeDeploy to deploy the application.
The pipeline has been operating successfully for several months and there have been no modifications. Following a recent change to the application's source code, AWS CodeDeploy has not deployed the updates application as expected.
What are the possible causes? (Choose two.) The change was not made in the master branch of the AWS CodeCommit repository. One of the earlier stages in the pipeline failed and the pipeline has terminated. One of the Amazon EC2 instances in the company's AWS CodePipeline cluster is inactive. The AWS CodePipeline is incorrectly configured and is not executing AWS CodeDeploy. AWS CodePipeline does not have permissions to access AWS CodeCommit. 106. AWS CodeBuild builds code for an application, creates the Docker image, pushes the image to Amazon Elastic Container Registry (Amazon ECR), and tags the image with a unique identifier.
If the Developers already have AWS CLI configured on their workstations, how can the Docker images be pulled to the workstations? Run the following: docker pull REPOSITORY URI : TAG Run the output of the following: aws ecr get-login and then run: docker pull REPOSITORY URI : TAG Run the following: aws ecr get-login and then run: docker pull REPOSITORY URI : TAG Run the output of the following: aws ecr get-download-url-for-layer and then run: docker pull REPOSITORY URI : TAG. 122. A company has multiple Developers located across the globe who are updating code incrementally for a development project. When Developers upload code concurrently, internet connectivity is slow and it is taking a long time to upload code for deployment in AWS Elastic Beanstalk.
Which step will result in minimized upload and deployment time with the LEAST amount of administrative effort? Allow the Developers to upload the code to an Amazon S3 bucket, and deploy it directly to Elastic Beanstalk. Allow the Developers to upload the code to a central FTP server to deploy the application to Elastic Beanstalk. Create an AWS CodeCommit repository, allow the Developers to commit code to it, and then directly deploy the code to Elastic Beanstalk. Create a code repository on an Amazon EC2 instance so that all Developers can update the code, and deploy the application from the instance to Elastic Beanstalk. A company needs a fully-managed source control service that will work in AWS. The service must ensure that revision control synchronizes multiple distributed repositories by exchanging sets of changes peer-to-peer. All users need to work productively even when not connected to a network.
Which source control service should be used? Subversion AWS CodeBuild AWS CodeCommit AWS CodeStar. 137. A Developer must deploy a new AWS Lambda function using an AWS CloudFormation template.
Which procedures will deploy a Lambda function? (Select TWO.) Upload the code to an AWS CodeCommit repository, then add a reference to it in an AWS::Lambda::Function resource in the template. Create an AWS::Lambda::Function resource in the template, then write the code directly inside the CloudFormation template. Upload a .ZIP file containing the function code to Amazon S3, then add a reference to it in an AWS::Lambda::Function resource in the template. Upload a .ZIP file to AWS CloudFormation containing the function code, then add a reference to it in an AWS::Lambda::Function resource in the template. Upload the function code to a private Git repository, then add a reference to it in an AWS::Lambda::Function resource in the template. 153. An application that runs on an Amazon EC2 instance needs to access and make API calls to multiple AWS services.
What is the MOST secure way to provide access to the AWS services with MINIMAL management overhead? Use AWS KMS to store and retrieve credentials. Use EC2 instance profiles. Use AWS root user to make requests to the application. Store and retrieve credentials from AWS CodeCommit. 155. A company has three different environments: Development, QA, and Production. The company wants to deploy its code first in the Development environment, then QA, and then Production.
Which AWS service can be used to meet this requirement? Use AWS CodeCommit to create multiple repositories to deploy the application. Use AWS CodeBuild to create, configure, and deploy multiple build application projects. Use AWS Data Pipeline to create multiple data pipeline provisions to deploy the application Use AWS CodeDeploy to create multiple deployment groups. 186. A Developer is trying to deploy a serverless application using AWS CodeDeploy. The application was updated and needs to be redeployed.
What file does the Developer need to update to push that change through CodeDeploy? dockerrun.aws.json buildspec.yml appspec.yml ebextensions.config. 190. A Developer accesses AWS CodeCommit over SSH. The SSH keys configured to access AWS CodeCommit are tied to a user with the following permissions: "codecommit:CreateBranch" "codecommit:DeleteBranch" "codecommit:Put*" "codecommit:Update*" "codecommit:*". A company needs a version control system for collaborative software development. Features of the system must include the following:
✑ Support for batches of changes across multiple files
✑ Parallel branching
✑ Version tracking
Which AWS service will meet these requirements? AWS CodePipeline Amazon S3 AWS Code Build AWS CodeCommit. 197. A company is using continuous integration and continuous delivery systems. A Developer now needs to automate a software package deployment to both Amazon EC2 instances and virtual servers running on-premises.
Which AWS service should be used to accomplish this? AWS CodePipeline AWS CodeBuild AWS Elastic Beanstalk AWS CodeDeploy. 202. A Development team would like to migrate their existing application code from a GitHub repository to AWS CodeCommit.
What needs to be created before they can migrate a cloned repository to CodeCommit over HTTPS? A GitHub secure authentication token A public and private SSH key file A set of Git credentials generated from IAM An Amazon EC2 IAM role with CodeCommit permissions.
