A Security Team Requires All Amazon EBS Volumes That Are

question 559

Multiple Choice

A Security team requires all Amazon EBS volumes that are attached to an Amazon EC2 instance to have AWS Key Management Service (AWS KMS) encryption enabled. If encryption is not enabled, the company's policy requires the EBS volume to be detached and deleted. A DevOps Engineer must automate the detection and deletion of unencrypted EBS volumes. Which method should the Engineer use to accomplish this with the LEAST operational effort?

• A) Create an Amazon CloudWatch Events rule that invokes an AWS Lambda function when an EBS volume is created. The Lambda function checks the EBS volume for encryption. If encryption is not enabled and the volume is attached to an instance, the function deletes the volume.
• B) Create an AWS Lambda function to describe all EBS volumes in the region and identify volumes that are attached to an EC2 instance without encryption enabled. The function then deletes all non-compliant volumes. The AWS Lambda function is invoked every 5 minutes by an Amazon CloudWatch Events scheduled rule.
• C) Create a rule in AWS Config to check for unencrypted and attached EBS volumes. Subscribe an AWS Lambda function to the Amazon SNS topic that AWS Config sends change notifications to. The Lambda function checks the change notification and deletes any EBS volumes that are non-compliant.
• D) Launch an EC2 instance with an IAM role that has permissions to describe and delete volumes. Run a script on the EC2 instance every 5 minutes to describe all EBS volumes in all regions and identify volumes that are attached without encryption enabled. The script then deletes those volumes.
