A server administrator needs to check remotely for unnecessary running services across 12 servers. Which of the following tools should the administrator use?

The correct answer is B. A port scanner. A port scanner (e.g., Nmap) remotely probes target hosts and reports which TCP/UDP ports are open, directly revealing which services are running on each server. Scanning 12 servers in a single sweep makes this highly efficient for auditing unnecessary services. DLP (A) is a…

Explanation

A port scanner (e.g., Nmap) remotely probes target hosts and reports which TCP/UDP ports are open, directly revealing which services are running on each server. Scanning 12 servers in a single sweep makes this highly efficient for auditing unnecessary services. DLP (A) is a Data Loss Prevention tool focused on preventing unauthorized data exfiltration, not service enumeration. Anti-malware (C) scans for malicious software but does not enumerate running services. A network sniffer (D) captures packets in transit and would require active traffic to infer services; it is not designed for a structured, remote service audit across multiple hosts.
