CertNexus Certified Cyber Secure Coder (CSC) — Question 47

Which of the following attacks involves sending a large amount of spoofed User Datagram Protocol (UDP) traffic to a router’s broadcast address within a network?

Answer options

• A. Land attack
• B. Fraggle attack
• C. Smurf attack
• D. Teardrop attack

Correct answer: C

Explanation

The correct answer is C, the Smurf attack, which utilizes spoofed UDP packets sent to a broadcast address, resulting in amplified traffic directed at the target. Option A, the Land attack, is a different technique that targets a system with spoofed packets sent to its own IP address. Option B, the Fraggle attack, is similar but uses ICMP instead of UDP, while Option D, the Teardrop attack, exploits vulnerabilities in the TCP/IP stack by sending malformed packets.
