300-120 WLSI: Implementing Cisco Wireless Advanced Solutions

QuestionQ54

Location Services

An engineer has just added a new MSE to Cisco Prime Infrastructure and needs to synchronize the MSE with a Cisco 5520 WLC located behind a firewall in a DMZ. NMSP messages are observed failing between the devices.

Which traffic must the firewall permit so that the MSE and WLC can communicate through NMSP?

Explanation

NMSP communication between a Cisco Mobility Services Engine and a wireless LAN controller uses TCP port 16113, so the firewall must allow TCP 16113 between the MSE and WLC. TCP 1613 is the strongest distractor because it has the correct transport protocol but the wrong port number.
