Question

Sniffer turns the NIC of a system to the promiscuous mode so that it listens to all the data transmitted on its segment. It can constantly read all information entering the computer through the NIC by decoding the information encapsulated in the data packet. Passive sniffing is one of the types of sniffing. Passive sniffing refers to:

Sniffing through a hub
Sniffing through a router
Sniffing through a switch
Sniffing through a bridge

Answer 1

Answer: Sniffing through a hub

Step-by-step explanation:

When we sniff through a hub we are able to listen to all the data transmitted through to and fro from all the computers in the network. So it is better to perform passive sniffing which includes Sniffing through a hub.
