Which document should be referenced for guidance on "Web management and Internet use"?

The correct choice refers to AFI 33-129, which outlines guidance on the management of web and internet resources within the organization. This document is essential for establishing the policies, responsibilities, and procedures related to web content, design, and the appropriate use of the internet in various contexts. It addresses the need for secure and effective web management, ensuring compliance with regulations and standards while providing clear instructions on managing official web presence.

In contrast, the other options are likely related to different aspects of information technology or communications but do not specifically pertain to web management or internet use. This focus makes the selected document the most relevant reference for anyone looking to understand or implement policies regarding web management in the organization.
