Which of the following would Sandy, a technician, find in a network map?

QoS standards are traffic prioritization policies configured on devices; they are part of network configuration documentation, not a visual network map.

Network maps (also called topology diagrams) document the physical layout of network infrastructure, including Main Distribution Frames (MDFs) and Intermediate Distribution Frames (IDFs). These are the central and secondary wiring closets where core and distribution switches, patch panels, and cabling terminate, making them essential elements of any accurate network map.

System logs are operational event records stored on individual devices or a SIEM system; they are not represented on a network map.

Firewall rules are access control policies documented in security policy files or runbooks, not in a network topology map.
