Answer: Data encryption in Amazon DynamoDB using AWS KMS for at-rest security.
The correct answer is A, as Amazon DynamoDB automatically encrypts all user data at rest. This encryption is applied by default and uses encryption keys stored in AWS Key Management Service (AWS KMS), ensuring enhanced security for sensitive data. While AWS does offer other services and features related to security and management, such as patching for EC2 instances, TLS certificate management, and network traffic encryption, these are not performed automatically in the same way as DynamoDB's encryption at rest. Specifically, for EC2 instances, AWS does not automatically patch the customer's operating systems or applications, and for network traffic, while AWS services may provide TLS encryption, it is not an AWS-automated task for the user's own network traffic outside of AWS-managed services.
