The EC2 instance has an IAM role with an attached policy. What action should the developer take to resolve the permissions issue?
Explanation:
The correct answer is C. To resolve the 'Access Denied' error, the EC2 instance needs a trust policy that specifies the EC2 service principal and associates this policy with the IAM role. This trust policy allows the specified entity (in this case, the EC2 instance) to assume the role and perform the required actions on the DynamoDB table. Creating this trust policy ensures that the EC2 instance is properly authorized to access the DynamoDB resources.
