Which of the following roles has the least access to sensitive data?

The role of an Account Viewer has the least access to sensitive data because this role is primarily focused on providing a read-only view of account-related information without the permissions to make changes or access detailed sensitive data that could be available to other roles. By design, the Account Viewer is intended for oversight and monitoring purposes, ensuring that users can review account statuses and general information, but not delve into intricate details or sensitive financial or configuration data.

In contrast, roles like Finance Admin would have broader access that includes sensitive financial data, and Monitoring Viewer or Log Viewer roles are likely to enable interaction with system metrics or logs, which can contain sensitive information relevant to system performance and security. Hence, these roles inherently possess greater access to potentially sensitive data compared to an Account Viewer.
