Refer to the exhibit. An Ethernet Local Area Network (LAN) consists of the components shown in the diagram. Assuming there are no VLANs, how many broadcast domains are on this LAN?

The correct answer is A. 1. A broadcast domain is a logical division of a network in which all nodes can reach each other with broadcast frames (Layer 2). Devices within the same broadcast domain receive broadcast packets sent by others. Multiple users connect to hubs. Hubs are Layer 1 devices and do not…

Explanation

A broadcast domain is a logical division of a network in which all nodes can reach each other with broadcast frames (Layer 2). Devices within the same broadcast domain receive broadcast packets sent by others. Multiple users connect to hubs. Hubs are Layer 1 devices and do not break broadcast domains. They simply replicate incoming electrical signals to all ports. Hubs are then connected to switches. Switches, unless VLANs are configured, forward broadcasts to all ports except the incoming one, effectively keeping all devices in the same broadcast domain. The two switches are connected together without VLAN segmentation. The entire LAN depicted is a single Layer 2 broadcast domain. There are no routers or VLANs to break or separate the domain.
