Question: 1
A company is implementing an application on Amazon EC2 instances. The application needs to
process incoming transactions. When the application detects a transaction that is not valid, the
application must send a chat message to the company's support team. To send the message, the
application needs to retrieve the access token to authenticate by using the chat API.

A developer needs to implement a solution to store the access token. The access token must be
encrypted at rest and in transit. The access token must also be accessible from other AWS accounts.

Which solution will meet these requirements with the LEAST management overhead?

A. Use an AWS Systems Manager Parameter Store SecureString parameter that uses an AWS Key
Management Service (AWS KMS) AWS managed key to store the access token. Add a resource-based
policy to the parameter to allow access from other accounts. Update the IAM role of the EC2
instances with permissions to access Parameter Store. Retrieve the token from Parameter Store with
the decrypt flag enabled. Use the decrypted access token to send the message to the chat.

B. Encrypt the access token by using an AWS Key Management Service (AWS KMS) customer
managed key. Store the access token in an Amazon DynamoDB table. Update the IAM role of the EC2
instances with permissions to access DynamoDB and AWS KMS. Retrieve the token from DynamoDB.
Decrypt the token by using AWS KMS on the EC2 instances. Use the decrypted access token to send
the message to the chat.

C. Use AWS Secrets Manager with an AWS Key Management Service (AWS KMS) customer managed
key to store the access token. Add a resource-based policy to the secret to allow access from other
accounts. Update the IAM role of the EC2 instances with permissions to access Secrets Manager.
Retrieve the token from Secrets Manager. Use the decrypted access token to send the message to
the chat.

D. Encrypt the access token by using an AWS Key Management Service (AWS KMS) AWS managed
key. Store the access token in an Amazon S3 bucket. Add a bucket policy to the S3 bucket to allow
access from other accounts. Update the IAM role of the EC2 instances with permissions to access
Amazon S3 and AWS KMS. Retrieve the token from the S3 bucket. Decrypt the token by using AWS
KMS on the EC2 instances. Use the decrypted access token to send the massage to the chat.
