Computer Hacking Forensic Investigator (CHFI v10) — Question 238

Jessica works as systems administrator for a large electronics firm. She wants to scan her network quickly to detect live hosts by using ICMP ECHO Requests.
What type of scan is Jessica going to perform?

Answer options

• A. Tracert
• B. Smurf scan
• C. Ping trace
• D. ICMP ping sweep

Correct answer: D

Explanation

The correct answer is D, ICMP ping sweep, which specifically refers to using ICMP ECHO Requests to identify live hosts on a network. Option A, Tracert, is used for tracing the path of packets and does not identify live hosts. Option B, Smurf scan, involves a specific type of denial-of-service attack and is not a scanning method for detecting hosts. Option C, Ping trace, is not a recognized scanning method in networking.
