Which network tool exploits weaknesses in DHCP and other protocols and serves as a testing framework?

• A. DHCP Attack
• B. Arp
• C. VoIP Call Tapping
• D. Yersinia

Answer: (D)

This question is about a network security tool that serves as a testing framework to probe weaknesses in multiple Layer 2 protocols, including DHCP. Yersinia is designed to craft and send protocol-specific frames to trigger vulnerabilities in devices implementing these protocols, making it ideal for assessing how robust a network’s DHCP and other protocol implementations are under attack conditions. It provides a modular environment to perform various protocol-based attacks and fuzzing campaigns, which is exactly what a testing framework is meant to do.

Other options don’t fit this role as well. A DHCP-focused attack implies a single-protocol attack tool rather than a broader testing framework. ARP refers to a protocol itself, not a framework for testing multiple protocols. VoIP Call Tapping is about intercepting communications, not about testing protocol weaknesses in a general sense.
