Explanation

The presence of both regulated (users and lab) and non-regulated (servers, HVAC) networks in Building 2 increases the risk of zone traversal, where traffic or attacks could cross from less secure to more secure network zones. Addressing zone traversal first helps protect regulated environments from unauthorized access originating in less protected VLANs.
