What is a primary characteristic of a multilayer switch?

It only operates on Layer 1 and Layer 2
It includes Layer 3 (routing) functionality
It is designed purely for application-specific functions
It does not support Power over Ethernet

The correct answer is: It includes Layer 3 (routing) functionality

A multilayer switch is unique because it combines the functionalities of both a traditional switch and a router within a single device. By including Layer 3 (routing) functionality, a multilayer switch can make decisions based on the IP address, thus performing routing tasks in addition to switching tasks typical of Layer 1 and Layer 2. This capability allows for efficient data packet handling and the ability to route traffic intelligently across different VLANs, making it highly beneficial in complex network environments where both switching and routing are required. Including Layer 3 functionality not only enhances the switch's performance in managing data traffic but also simplifies network design by reducing the need for separate devices for these distinct functions. This versatility makes multilayer switches important in large-scale networks where performance and efficiency are crucial.
