The AWS Systems Manager Parameter Store Is Being Used to Store

Multiple Choice

The AWS Systems Manager Parameter Store is being used to store database passwords used by an AWS Lambda function.

When the function executes, this parameter cannot be retrieved as the result of an access denied error. Which of the following actions will resolve the access denied error?

A) Update the ssm.amazonaws.com principal in the KMS key policy to allow kms: Decrypt.
B) Update the Lambda configuration to launch the function in a VPC.
C) Add a policy to the role that the Lambda function uses, allowing kms: Decrypt for the KMS key.
D) Add lambda.amazonaws.com as a trusted entity on the IAM role that the Lambda function uses.
