CompTIA Security+ (SY0-501) — Question 692

A technician has been asked to document which services are running on each of a collection of 200 servers. Which of the following tools BEST meets this need while minimizing the work required?

Answer options

• A. Nmap
• B. Nslookup
• C. Netcat
• D. Netstat

Correct answer: A

Explanation

Nmap is designed for network discovery and security auditing, making it the best choice for identifying services running on multiple servers efficiently. Nslookup is used for querying DNS records, Netcat is a networking utility for reading and writing data across network connections, and Netstat displays network connections but does not provide comprehensive service information across multiple servers.
