A security analyst is responsible for the completion of a vulnerability assessment at a regional healthcare facility. The analyst reviews the following Nmap output: Which of the following is MOST…

SMB normally operates on TCP port 445; a script probing UDP 445 is specifically crafted to detect servers with non-standard or unsafe configurations that expose that port over UDP, which is characteristic of misconfigured or vulnerable hosts. This type of scan is used during vulnerability assessments to flag anomalous service exposure rather than to interact with or control SMB services directly.

Running SMB servers would require issuing administrative start commands on target hosts; an Nmap script only sends network probes and analyzes the responses it receives.

Stopping services requires elevated administrative access and control-plane commands on the remote system, which is not a function of Nmap network scanning scripts.

Scanning for vulnerable SMB servers typically targets TCP 445 using exploit-reference scripts such as those checking for EternalBlue or MS17-010, not UDP 445 which indicates unsafe configuration detection rather than exploit confirmation.
