Palo Alto Networks Certified Network Security Engineer (PCNSE) — Question 61

Which User-ID method maps IP addresses to usernames for users connecting through a web proxy that has already authenticated the user?

Answer options

• A. syslog listening
• B. server monitoring
• C. client probing
• D. port mapping

Correct answer: A

Explanation

The correct answer is A, syslog listening, because it captures log data from the web proxy that includes user authentication details. The other options—server monitoring, client probing, and port mapping—do not directly facilitate the mapping of IP addresses to usernames in the context of authenticated web proxy connections.
