A technician was assigned a help desk ticket and resolved the issue. Which of the following should the technician update to assist other technicians in resolving similar issues?

End user training is for instructing users on how to operate systems or avoid issues, not for sharing technical resolutions among IT staff.

Progress notes document the steps taken for a specific individual ticket but are generally not structured or indexed to serve as a comprehensive resource for generalized future problem-solving by other technicians.

The knowledge base is a centralized repository of information, solutions, and best practices that other technicians can consult to efficiently resolve similar issues in the future, promoting consistency and reducing resolution times.

An acceptable use policy document outlines rules for computer system usage and is unrelated to documenting technical solutions for troubleshooting.
