ACL Fundamentals - Block a Single Host #1

A management workstation is reachable from a guest segment that should not be able to contact it.

场景

Alder Health's guest segment can reach a management workstation that should be isolated from it, while the workstation still needs to reach the router for administration. The security team wants the single-host exception blocked without taking the whole management segment offline. Identify the traffic boundary and apply the narrow restriction, then verify that permitted connectivity remains available.
