Final answer:
Joe is authoring a type of document known as a guideline, which recommends methods for system administrators to encrypt laptops in compliance with their organization's encryption requirements.
Step-by-step explanation:
Joe is drafting a document that outlines how system administrators can comply with the organizational requirement to encrypt all laptops. This type of document falls into the category of a guideline. Guidelines provide recommendations or suggestions that are not mandatory but are recommended for achieving compliance with policies or standards. Unlike a policy, which is a rule that must be followed within an organization, or a standard, which sets an established level of quality or attainment, a guideline is more advisory in nature. A procedure, on the other hand, is a step-by-step instructional document. Hence, Joe's document likely represents a guideline providing recommended methods for encrypting laptops, ensuring system administrators have guidance but also flexibility in how they meet the organization's encryption requirements.
