A developer is setting up a deployment pipeline. The pipeline includes an AWS CodeBuild build stage that requires access to a database to run integration tests. The developer is using a buildspec.yml file to configure the database connection. Company policy requires automatic rotation of all database credentials.
Which solution will handle the database credentials MOST securely?

• A.  Retrieve the credentials from an environment variable that contains the connection string in plaintext.Configure an Amazon EventBridge event to rotate the credentials.
• B.  Retrieve the credentials from an environment variable that is linked to a SecureString parameter in AWS Systems Manager Parameter Store. Configure Parameter Store for automatic rotation.
• C.  Retrieve the credentials from an environment variable that is linked to an AWS Secrets Manager secret.
  Configure Secrets Manager for automatic
  rotation.
• D.  Retrieve the credentials from variables that are hardcoded in the buildspec.yml file. Configure an AWS Lambda function to rotate the credentials.

A developer maintains an Amazon API Gateway REST API. Customers use the API through a frontend UI and Amazon Cognito authentication.
The developer has a new version of the API that contains new endpoints and backward-incompatible interface changes. The developer needs to provide beta access to other developers on the team without affecting customers.
Which solution will meet these requirements with the LEAST operational overhead?

• A.  Specify new API Gateway endpoints for the API endpoints that the developer wants to add.
• B.  Implement a query parameter in the API application code that determines which code version to call.
• C.  Define a new API Gateway API that points to the new API application code. Instruct the other developers to point the endpoints to the new API.
• D.  Define a development stage on the API Gateway API. Instruct the other developers to point the endpoints to the development stage.

A development team wants to build a continuous integration/continuous delivery (CI/CD) pipeline. The team is using AWS CodePipeline to automate the code build and deployment. The team wants to store the program code to prepare for the CI/CD pipeline.
Which AWS service should the team use to store the program code?

• A.  AWS CodeDeploy
• B.  Amazon CodeGuru
• C.  AWS CodeArtifact
• D.  AWS CodeCommit

A developer is building an application that uses an AWS Lambda function to process data. The application requires minimum latency. The Lambda function must have predictable function start times. All setup activities for the execution environment must happen before invocation of the Lambda function.
Which solution will meet these requirements?

• A.  Optimize the static initialization code that runs when a new execution environment is prepared for the first time. Decrease and compress the size of the Lambda function package and the imported libraries and dependencies.
• B.  Increase the memory of the Lambda function to the maximum amount. Configure an Amazon EventBridge rule to schedule invocations of the Lambda function every minute to keep the execution environment active.
• C.  Publish a new version of the Lambda function. Configure provisioned concurrency for the Lambda function with the required minimum number of execution environments.
• D.  Increase the reserved concurrency of the Lambda function to the maximum value for unreserved account concurrency. Run any setup activities manually before the initial invocation of the Lambda function.

When a developer tries to run an AWS Code Build 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?

• A.  Add the export LC-_ALL" on _ US, tuft" command to the pre _ build section to ensure POSIX Localization.
• B.  Use Amazon Cognate to store key-value pairs for large numbers of environment variables
• C.  Update the settings for the build project to use an Amazon S3 bucket for large numbers of environment variables
• D.  Use AWS Systems Manager Parameter Store to store large numbers ot environment variables
