A large municipal VLAN spans hundreds of wired printers and IoT endpoints; wireless clients on the same broadcast domain see airtime spikes from ARP and other BCMC floods. Which remediation best protects WLAN airtime?
Select an answer to reveal the explanation.
Short Explanation
Broadcasts on Wi-Fi are like the PA system reading every memo out loud—everyone stops to listen. Huge VLANs dump ARP and friends onto scarce airtime. Rate-limit or filter BCMC to the WLAN and keep broadcast domains smaller.
Full Explanation
Broadcast and multicast frames are typically sent at low basic rates and interrupt unicast efficiency across the BSS. Large Layer-2 domains magnify ARP and other BCMC onto wireless. Best practice is to rate-limit/filter BCMC at the AP/controller edge, use directed multicast techniques where supported, and segment VLANs. Raising beacon power or widening channels does not solve BCMC airtime waste.
