Answer options
A: Captive Portal Correct answer
B: Domain server monitoring Correct answer
C: Reverse DNS lookup
D: User behaviour recognition
E: Client probing Correct answer
Correct Answer:
A. Captive Portal; B. Domain server monitoring; E. Client probing
Explanation

User-ID collects IP-to-username mappings through several mechanisms.
• Captive Portal can directly prompt unauthenticated users and bind the supplied credentials to their source IP.
• Server Monitoring (domain controller log reading) passively learns logon events and maps usernames to IPs.
• Client Probing (UDP/TCP or HTTP probes) actively queries hosts to validate or discover logged-in users. These three mechanisms are officially supported methods for obtaining user mappings.

Why Incorrect

C. Reverse DNS only resolves host names; it does not supply username information.
D. User behaviour recognition is an analytics function, not a method for creating IP-to-user mappings.
