Understanding Cisco Cybersecurity Fundamentals (SECFND, legacy) — Question 38

A ping attack that exploits the broadcast IP address in a subnet is referred to as what type of attack?

Answer options

• A. red rat
• B. fraggle
• C. smurf
• D. SYN flood
• E. firewalk

Correct answer: C

Explanation

The correct answer is C, smurf, which refers to a type of DDoS attack that sends ICMP echo request packets to the broadcast address of a subnet, causing all devices to respond to the target. The other options do not involve using a broadcast address in this manner; for example, A (red rat) is not a recognized attack, B (fraggle) involves UDP packets, D (SYN flood) targets TCP connections, and E (firewalk) is a technique for network scanning.
