Question 1

A company mandates that all employees access secrets and parameters by using AWS Systems Manager Parameter Store. Every secret must rotate automatically every 60 days. A DevOps engineer needs to add a new secret that allows an application to access an Amazon ElastiCache (Redis OSS) cluster. Which solution satisfies these requirements with the LEAST operational overhead?

Create the secret in AWS Secrets Manager. Enable managed rotation. Set the rotation frequency to 60 days. Configure the application to reference the secret value by using the fully qualified path in Parameter Store.

Create the secret in Parameter Store. Enable automatic rotation. Set the rotation frequency to 60 days. Configure the application to reference the secret value by using the fully qualified path in Parameter Store.

Create the secret in Parameter Store. Create an AWS Lambda function to rotate the secret. Configure an Amazon EventBridge event to invoke the Lambda function every 60 days. Configure the application to provide the unique secret name to Parameter Store to retrieve the secret.

Create the secret in AWS Secrets Manager. Enable rotation by AWS Lambda function. Use the Secrets Manager provided Lambda template for ElastiCache (Redis OSS) secrets. Set the rotation schedule to 60 days. Set a rotation window duration in Secrets Manager. Configure the application to provide the full reserved path to Parameter Store when the application accesses the secret.

Question 2

A development team manually creates a local artifact. The team transfers the artifact to an Amazon S3 bucket to support an application. The application uses a local cache that must be cleared when the team deploys the application to Amazon EC2 instances. For every deployment, the team runs a command to clear the cache, download the artifact from the S3 bucket, and unzip the artifact to finish the deployment. The development team wants to migrate the deployment process to CI/CD and track the progress of every deployment. Which combination of actions meets these requirements with the MOST operational efficiency? (Choose three.)

Set up an AWS CodeConnections compatible Git repository. Allow developers to merge code into the repository. Use AWS CodeBuild to build an artifact and copy the object into the S3 bucket. Configure CodeBuild to run for every merge into the main branch.

Create a custom script to clear the cache. Specify the script in the BeforeInstall lifecycle hook in the AppSpec file.

Create user data for each EC2 instance that contains the cache clearing script. Test the application after deployment. If the deployment is not successful, then redeploy.

Use AWS CodePipeline to deploy the application. Set up an AWS CodeConnections compatible Git repository. Allow developers to merge code into the repository as a source for the pipeline.

Use AWS CodeBuild to build the artifact and place the artifact in the S3 bucket. Use AWS CodeDeploy to deploy the artifact to EC2 instances.

Use AWS Systems Manager to fetch the artifact from the S3 bucket and to deploy the artifact to all the EC2 instances.
