A port authority must keep police records and public Wi-Fi on separate broadcast domains in the same closet, then carry both upstream. Which design choice correctly achieves that separation?
Select an answer to reveal the explanation.
Short Explanation
Broadcast domains are like separate waiting rooms in one building. Different VLANs give each crowd its own room; an 802.1Q trunk is the hallway that carries both upstairs without mixing the crowds. Same VLAN with fancy DHCP still shares the same noisy room.
Full Explanation
VLANs partition Layer-2 broadcast domains so police records traffic and public Wi-Fi do not share floods, ARP, or accidental bridging. Access ports map to the correct VLAN, and the uplink to distribution is typically an 802.1Q trunk carrying both tags. Private addressing, DHCP scopes alone, or bridging both networks with ACL hopes do not create sound Layer-2 isolation. Segment first with VLANs, then apply higher-layer controls as needed.
