A tax assessor extends one VLAN across multiple buildings on trunks and asks when that pattern becomes an operational smell. What is the core concern?
Select an answer to reveal the explanation.
Short Explanation
One VLAN stretched across buildings is one big fishbowl—every broadcast and loop splash hits everyone. Trunks make the stretch easy; they don’t make the blast radius small. When the assessor’s domain feels fragile, route between buildings instead of bridging everything.
Full Explanation
Extending a single VLAN across buildings creates a wide Layer-2 failure domain: broadcasts, unknown unicasts, STP events, and loops propagate farther. Trunks are the transport, not a cure for that risk. A common enterprise remedy is to terminate VLANs at distribution or building edge and route between sites. Claims that trunks cannot carry multiple VLANs, that tags expire by hop count, or that VTP transparent forbids multi-building VLANs are incorrect.
