CompTIA Network+ (N10-009) — Question 219
Network administrators are using the Telnet protocol to administer network devices that are on the 192.168.1.0/24 subnet. Which of the following tools should the administrator use to best identify the devices?
Answer options
- A. dig
- B. nmap
- C. tracert
- D. telnet
Correct answer: B
Explanation
The correct answer is B, nmap, which is specifically designed for network discovery and security auditing, making it ideal for identifying devices on a subnet. Option A, dig, is used for DNS lookups and is not suitable for network scanning. Option C, tracert, is used to trace the path to a network host and does not identify devices. Option D, telnet, is a protocol for remote administration but does not assist in discovering devices on the network.
