Explanation
Terminating ALL backbone cables and ER links at the MC (Main Cross-connect / Campus Distributor) provides maximum flexibility because it sits at the apex of the hierarchical star - every path in the network flows through it, allowing any-to-any patching between campuses, buildings, or equipment rooms from a single central point. The HC (FD) (Choice A) is wrong because it is the lowest tier, handling only horizontal runs to work areas, not backbone interconnection. The IC (BD) (Choice B) is only an intermediate node serving individual buildings and cannot provide campus-wide, universal cross-connection. The TR (Choice C) is a physical location (the room) rather than a cross-connect level in the hierarchy, so it is not the answer to where cables terminate in the topology. Memory tip: Link "Maximum" to "MC" - the Main cross-connect is the Maximum point of control, and centralizing all terminations there gives you the most options for re-routing or reconfiguring without touching multiple rooms.
