City WLAN carries corporate, guest, and IoT SSIDs. What wired-side practice is essential?
Select an answer to reveal the explanation.
Short Explanation
Different Wi-Fi neighborhoods need different streets on the wire. Corp, guest, and IoT belong on separate VLANs with deliberate paths between them. One big flat LAN is how a guest phone meets a domain controller.
Full Explanation
Wired VLAN segmentation mapped from SSID/user role separates trust zones for corporate, guest, and IoT traffic and enables policy enforcement at Layer 3/ACL boundaries. Flattening all wireless traffic into one VLAN or relying only on SSID names without VLAN separation fails to contain breaches or misbehaving IoT.
