What is the term for a virtual Layer 2 switch that connects multiple ports into the same broadcast domain?

• A. Bridge
• B. Interfaces
• C. Terminal
• D. RouterOS

Answer: (A)

A bridge is the device that ties multiple ports into one Layer 2 network, creating a single broadcast domain. It works like a software switch: it learns which MAC addresses are reachable on each port and forwards frames only to the appropriate port, while unknown destinations are flooded. When you group several interfaces into one bridge, all those ports belong to the same L2 network, so broadcasts reach every port in that bridge. That’s why a virtual Layer 2 switch implemented as a bridge is described this way. Interfaces are just individual ports, not a device that connects multiple ports into one domain. Terminal is simply a command-line session, and RouterOS is the operating system itself, not the concept of a bridged L2 domain.
