Topic 1 Question 138
A company is using an AWS Key Management Service (AWS KMS) AWS owned key in its application to encrypt files in an AWS account. The company's security team wants the ability to change to new key material for new files whenever a potential key breach occurs. A security engineer must implement a solution that gives the security team the ability to change the key whenever the team wants to do so.
Which solution will meet these requirements?
Create a new customer managed key. Add a key rotation schedule to the key. Invoke the key rotation schedule every time the security team requests a key change.
Create a new AWS managed key. Add a key rotation schedule to the key. Invoke the key rotation schedule every time the security team requests a key change.
Create a key alias. Create a new customer managed key every time the security team requests a key change. Associate the alias with the new key.
Create a key alias. Create a new AWS managed key every time the security team requests a key change. Associate the alias with the new key.

Agree with option C AWS managed keys are KMS keys in your account that are created, managed, and used on your behalf by an AWS service integrated with AWS KMS

C is correct:
According to AWS documentation:
Customer managed keys provide full control over the lifecycle, including the ability to rotate and change the key material. Key aliases allow you to abstract the underlying key from the application, making it easier to switch to a new key without changing the application code. AWS owned keys and AWS managed keys do not provide the same level of control for key rotation and material changes as customer managed keys. By creating a key alias and associating it with a new customer managed key each time the security team requests a key change, you ensure that the encryption uses fresh key material while maintaining seamless integration with your application.
