Cisco 200-201 Exam - Topic 5 Question 130 Discussion

Posted by Socorro on Sep 26, 2026 at 09:05 AM

An engineer needs to discover alive hosts within the 192.168.1.0/24 range without triggering intrusive portscan alerts on the IDS device using Nmap. Which command will accomplish this goal?

Anmap --top-ports 192.168.1.0/24

Bnmap --sP 192.168.1.0/24

Cnmap -sL 192.168.1.0/24

Dnmap -sV 192.168.1.0/24

Suggested Answer: B

The -sP option in Nmap is used for host discovery without port scanning, which helps in identifying live hosts without triggering portscan alerts on IDS devices. It sends an ICMP echo request, a TCP SYN packet to port 443, a TCP ACK packet to port 80, and an ICMP timestamp request to each target IP address and waits for a response. Any responses are considered as indications of a live host.Reference:=Cisco Cybersecurity Operations Fundamentals - Module 5: Endpoint Threat Analysis and Computer Forensics

B is the right choice! It's a ping scan.

I’m leaning towards option B too, but I wonder if there’s a chance that it could still trigger some alerts.

I practiced a similar question, and I feel like -sL just lists targets without scanning, so it wouldn’t help here.

I’m not entirely sure, but I remember something about -sP being used for host discovery.

I think option B might be the right choice since it’s a ping scan, which should be less intrusive.
