Implementing and Operating Cisco Security Core Technologies (SCOR) — Question 454

Which attack type attempts to shut down a machine or network so that users are not able to access it?

Answer options

• A. bluesnarfing
• B. MAC spoofing
• C. smurf
• D. IP spoofing

Correct answer: C

Explanation

The correct answer is C, smurf, which is a type of denial-of-service attack that floods a target with ICMP packets, overwhelming it. A, bluesnarfing, refers to unauthorized access to information from a Bluetooth device, while B, MAC spoofing, involves changing the hardware address of a network interface. D, IP spoofing, is a technique used to send IP packets from a false (or 'spoofed') source address, which does not necessarily lead to shutting down access.
