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.

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.
