A team of developed is using an AWS CodePipeline pipeline as a continuous integration and continuous delivery (CI/CD) mechanism for a web application. A developer has written unit tests to programmatically test the functionality of the application code. The unit tests produce a test report that shows the results of each individual check. The developer now wants to run these tests automatically during the CI/CD process.

• A.  Add a new stage to the pipeline. Use AWS CodeBuild at the provider. Add the new stage before the stage that deploys code revisions to the test environment. Write a buildspec that fails the CodeBuild stage it any test does not pass. Use the test reports feature of CodeBuild to integrate the report with the CodeBuild console. View the test results in codeBuild Resolve any issues.
• B.  Add a new stage to the pipeline. Use AWS CodeBuild as the provider. Add the new stage after the stage that deploys code revisions to the test environment. Write a buildspec that fails the CodeBuild stage if any test does not pass. Use the test reports feature of Codebuild to integrate the report with the CodoBuild console. View the test results in CodeBuild Resolve any issues.
• C.  Write a Git pre-commit hook that runs the test before every commit. Ensure that each developer who is working on the project has the pre-commit hook instated locally. Review the test report and resolve any issues before pushing changes to AWS CodeCommit.
• D.  Add a new stage to the pipeline. Use Jenkins as the provider. Configure CodePipeline to use Jenkins to run the unit tests. Write a Jenkinsfile that fails the stage if any test does not pass. Use the test report plugin for Jenkins to integrate the repot with the Jenkins dashboard. View the test results in Jenkins.Resolve any issues.

A developer is building an image-processing application that includes an AWS Lambda function. The Lambda function moves images from one AWS service to another AWS service for image processing. For images that are larger than 2 MB, the Lambda function returns the following error: " Task timed out after 3.01 seconds. " The developer needs to resolve the error without modifying the Lambda function code.
Which solution will meet these requirements?

• A.  Configure provisioned concurrency for the Lambda function.
• B.  Request a concurrency quota increase for the Lambda function.
• C.  Increase the Lambda function's timeout value.
• D.  Configure the Lambda function to not move images that are larger than 2 MB.

A developer is integrating Amazon ElastiCache in an application. The cache will store data from a database.
The cached data must populate real-time dashboards. Which caching strategy will meet these requirements?

• A.  A write-behind cache
• B.  A write-through cache
• C.  A read-through cache
• D.  A lazy-loading cache

An online food company provides an Amazon API Gateway HTTP API 1o receive orders for partners. The API is integrated with an AWS Lambda function. The Lambda function stores the orders in an Amazon DynamoDB table.
The company expects to onboard additional partners Some to me panthers require additional Lambda function to receive orders. The company has created an Amazon S3 bucket. The company needs 10 store all orders and updates m the S3 bucket for future analysis How can the developer ensure that an orders and updates are stored to Amazon S3 with the LEAST development effort?

• A.  Use Amazon Kinesis Data Streams to create a new data stream. Modify the Lambda function to publish orders to the oats stream Configure in data stream to write to the S3 bucket.
• B.  Create a new Lambda function and a new API Gateway API endpoint. Configure the new Lambda function to write to the S3 bucket. Modify the original Lambda function to post updates to the new API endpoint.
• C.  Enable DynamoDB Streams on me DynamoOB table. Create a new lambda function. Associate the stream ' s Amazon Resource Name (ARN) with the Lambda Function Configure the Lambda function to write to the S3 bucket as records appear in the table's stream.
• D.  Modify the Lambda function to punish to a new Amazon. Simple Lambda function receives orders.Subscribe a new Lambda function to the topic. Configure the new Lambda function to write to the S3 bucket as updates come through the topic.

A company has a web application that runs on Amazon EC2 instances with a custom Amazon Machine Image (AMI) The company uses AWS CloudFormation to provision the application The application runs in the us- east-1 Region, and the company needs to deploy the application to the us-west-1 Region An attempt to create the AWS CloudFormation stack in us-west-1 fails. An error message states that the AMI ID does not exist. A developer must resolve this error with a solution that uses the least amount of operational overhead Which solution meets these requirements?

• A.  Build the custom AMI in us-west-1 Create a new AWS CloudFormation template to launch the stack in us-west-1 with the new AMI ID
• B.  Change the AWS CloudFormation templates for us-east-1 and us-west-1 to use an AWS AMI.
  Relaunch the stack for both Regions.
• C.  Manually deploy the application outside AWS CloudFormation in us-west-1.
• D.  Copy the custom AMI from us-east-1 to us-west-1. Update the AWS CloudFormation template for us- west-1 to refer to AMI ID for the copied AMI Relaunch the stack
