Answer: A

Explanation:

Understand the Problem:

The requirement is to delete the CloudFormation stack without deleting the DynamoDB table.

Analyze the Requirements:

Ensure the DynamoDB table is preserved when the CloudFormation stack is deleted.

Evaluate the Options:

Option A: Add a Retain deletion policy to the DynamoDB resource.

The Retain policy ensures that the DynamoDB table is not deleted when the stack is deleted.

Option B: Add a Snapshot deletion policy to the DynamoDB resource.

Snapshot policy is not applicable to DynamoDB tables and would not retain the table itself.

Option C: Enable termination protection on the CloudFormation stack.

Prevents stack deletion entirely but does not specifically protect the DynamoDB table. Option D: Update the IAM policy with a Deny statement for dynamodb:DeleteTable. Prevents deletion of the table but is not a CloudFormation stack-specific solution. Select the Best Solution:

Option A: Adding a Retain deletion policy to the DynamoDB resource in the CloudFormation stack ensures the table is preserved when the stack is deleted.

Reference: AWS CloudFormation Deletion Policy

Using the Retain deletion policy ensures that the DynamoDB table is not deleted when the CloudFormation stack is deleted, preserving critical data.
