Que. 10) Identify the INCORRECT statement(s) related to Bridge and Switch (L2) in computer networks.
a) For small enterprises (without the need for features like QoS, VLANs, and STP), a switch is more economically suitable for segmenting traffic between two LANs than a bridge.
b) Switches operate in full-duplex mode, while bridges operate in half-duplex mode.
