According to the ServiceNow IT Asset Management (ITAM) Hardware Asset Management (HAM) learning path, the Hardware Asset dashboard is a feature that shows key metrics on your hardware and consumable models and assets for the entire asset life cycle.
The Hardware Asset dashboard is available with the Hardware Asset Management (HAM) application, which is a licensable application that provides advanced workflow, automation, and mobile capabilities to maintain your assets1.
To access the Hardware Asset dashboard, you need to have the ham_user role, which is the minimum role required to use the HAM application1.
The ham_user role grants you the permission to view and update hardware and consumable assets, transfer orders, disposal orders, and RMA requests1.
Therefore, the correct answer is option C, ham_user, as it is the minimum role required to use the Hardware Asset dashboard. Reference:
