What term describes a network segment where devices can reach each other through broadcast messages?

• A. Broadcast Domain
• B. Collision Domain
• C. VLAN
• D. Subnet

Answer: (A)

Broadcast domains describe the portion of the network where a broadcast frame is delivered to every device. In Ethernet, switches forward broadcast frames to all ports within the same Layer 2 domain, while routers do not forward broadcasts, creating boundaries. So the network segment where all devices can reach each other via broadcast messages is one broadcast domain. The other concepts operate differently: a collision domain is about shared access and possible collisions, VLANs define logical boundaries that separate broadcast domains, and subnets are IP-layer boundaries defined by addressing and routing rather than how broadcasts propagate at Layer 2.
