Name a tool designed to exploit weaknesses in DHCP and other protocols, used for testing networks?

• A. DHCP Attack
• B. Yersinia
• C. ARP
• D. Arpspoof

Answer: (B)

Yersinia is a specialized network attack tool that can craft and send frames to exploit weaknesses in multiple protocols, including DHCP, ARP, and other layer-2 services. This makes it ideal for testing how well a network and its devices handle protocol-level flaws and misconfigurations in a controlled environment. By simulating these protocol abuses, you can assess defenses like DHCP snooping, Dynamic ARP Inspection, and switch hardening.

The other options don’t fit as well. ARP is simply a protocol, not a testing tool. Arpspoof focuses on ARP spoofing to perform MITM, not on probing a range of protocol weaknesses. DHCP Attack is not a standard, recognized tool for this purpose.
