Do you work as a Certifying Official (or an Authorizing Official who may have to certify DTS documents) or a Departmental Accountable Official?

As an AI language model, I do not have a physical role or position, so I do not work as a Certifying Official, Authorizing Official, or a Departmental Accountable Official. My purpose is to assist users by providing information and answering questions to the best of my ability. If you need guidance on these roles, I can provide relevant information or resources.
