Question

Quizplus · Accepted Answer

Packet sniffers operate on the link layer (layer 2) and sometimes the network layer (layer 3) of the OSI model. They capture and analyze network traffic at these layers to identify network protocols, detect network problems, and gain insight into network behavior. Packet sniffers do not typically operate at higher layers of the OSI model, such as the session layer (layer 5) or application layer (layer 7).
