   A data engineer is using AWS CDK to define a data pipeline. The engineer needs to deploy the pipeline to multiple AWS accounts (dev, test, prod) with different configurations, such as bucket names and instance sizes. The engineer wants to avoid duplicating code. Which approach should the engineer use?

   • AUse a single CloudFormation template and manually edit it for each environment.
   • BUse CDK contexts and environment-specific stacks with parameters.
   • CUse AWS CodeCommit to store different branches for each environment.
   • DCreate a separate CDK app for each environment with duplicated code.

   A data engineer needs to deploy a new data pipeline that includes an S3 bucket, a Glue job, and a Redshift cluster. The deployment must be repeatable across multiple environments and tracked in version control. Which approach should the engineer use?

   • ACreate an AMI that includes the pipeline code and launch EC2 instances in each environment.
   • BManually create the resources in each environment and document the steps in a runbook.
   • CUse the AWS CLI to run a series of create commands in a shell script stored in a shared drive.
   • DWrite an AWS CloudFormation template that defines all resources and deploy it with different parameter values for each environment.

   A team is deploying a serverless data pipeline using AWS SAM. The pipeline includes a Lambda function that is triggered by an S3 event and writes to a DynamoDB table. The team wants to ensure that the Lambda function is not overwhelmed during peak loads and that the DynamoDB table can handle the write capacity. Which configuration should the team include in the SAM template?

   • ASet reserved concurrency on the Lambda function and enable DynamoDB auto scaling.
   • BSet the Lambda function's timeout to 15 minutes and increase DynamoDB's read capacity.
   • CEnable Lambda function URLs and use a load balancer.
   • DUse an SQS queue as an event source and set the batch size to 1.
