True or False? When a customer is denied access to an AWS service, they should first check to see if they have permissions to call that action on that resource.

When a customer is denied access to an AWS service, the first logical step is to review the permissions associated with their Identity and Access Management (IAM) role or user. AWS provides a comprehensive permissions framework that allows customers to define who can access specific AWS resources and what actions they are allowed to perform. If access is denied, it commonly indicates that the necessary permissions have not been granted to the user or role attempting to perform the action.

In many cases, when a user receives an "Access Denied" error, it is indeed a direct result of insufficient permissions. Therefore, confirming whether the user has the required permissions to call the specific action on the targeted resource is a critical step in troubleshooting the issue. This process ensures that the user's access rights are properly configured and aligned with their intended actions within the AWS environment.

While various reasons can lead to access denial, starting with permission checks is a fundamental and effective approach in most scenarios involving AWS resource access. This aligns with best practices for managing identity and access within AWS.
