Sniffs traffic over a network or a part of the network. Which term matches this description?

• A. Packet Sniffing
• B. Wire Sniffing
• C. Rainbow Table Attack
• D. Distributed Network Attack

Answer: (A)

Packet sniffing is the act of capturing network packets as they travel across a network or a segment of it. A packet sniffer places the network interface into promiscuous mode (or monitor mode on wireless) to observe traffic that may not be addressed to the host, allowing you to inspect headers and payloads. This directly describes sniffing traffic across a network. In practice, packet sniffing can be used for legitimate network troubleshooting or for malicious eavesdropping if protections like encryption and proper access controls aren’t in place. The other terms don’t describe this activity: a rainbow table attack involves cracking password hashes with precomputed tables, and a distributed network attack refers to coordinated assaults from multiple machines. The idea of wire sniffing isn’t a standard technical term. So the best match is packet sniffing.
