What term defines a portion of a network limited by its router connection to a group of hosts on a LAN?

• A. Broadcast Domains
• B. Collision Domains
• C. VLAN
• D. Subnets

Answer: (A)

A broadcast domain is the part of a network where broadcast traffic is propagated. Routers do not forward broadcast frames, so they create boundaries between these domains. When a router connects to a group of hosts on a LAN, that group shares the same broadcast domain, meaning any broadcast (like ARP or DHCP requests) is received by all devices in that group, but not by devices beyond the router. Subnets and VLANs relate to routing and segmentation, but the defining feature described—being limited by the router connection to a set of hosts—points to the broadcast domain concept.
