A company uses AWS CodeCommit for source code control. Developers apply their changes to various feature branches and create pull requests to move those changes to the main branch when the changes are ready for production.

The developers should not be able to push changes directly to the main branch. The company applied the AWSCodeCommitPowerUser managed policy to the developers' IAM role, and now these developers can push changes to the main branch directly on every repository in the AWS account.

What should the company do to restrict the developers' ability to push changes to the main branch directly?

A. Create an additional policy to include a Deny rule for the GitPush and PutFile actions. Include a restriction for the specific repositories in the policy statement with a condition that references the main branch.

B. emove the IAM policy, and add an AWSCodeCommitReadOnly managed policy. Add an Allow rule for the GitPush and PutFile actions for the specific repositories in the policy statement with a condition that references the main branch.

C. Modify the IAM policy. Include a Deny rule for the GitPush and PutFile actions for the specific repositories in the policy statement with a condition that references the main branch.

D. Create an additional policy to include an Allow rule for the GitPush and PutFile actions. Include a restriction for the specific repositories in the policy statement with a condition that references the feature branches.

A DevOps engineer is building a solution that uses Amazon Simple Queue Service (Amazon SQS) standard queues. The solution also includes an AWS Lambda function and an Amazon DynamoDB table. The Lambda function pulls content from an SQS queue event source and writes the content to the DynamoDB table.

The solution must maximize the scalability of Lambda and must prevent successfully processed SQS messages from being processed multiple times.

Which solution will meet these requirements?

A. Decrease the batch window to 1 second when configuring the Lambda function's event source mapping.

B. Decrease the batch size to 1 when configuring the Lambda function's event source mapping.

C. Include the ReportBatchItemFailures value in the FunctionResponseTypes list in the Lambda function's event source mapping.

D. Set the queue visibility timeout on the Lambda function's event source mapping to account for invocation throttling of the Lambda function.
