A network engineer has been hired to perform a new MSE implementation on an existing network.
The MSE must be installed in a different network than the Cisco WLC.
Which configuration allows the devices to communicate over NMSP?

A. B. C. D.B.
The correct answer is D: Allow TCP/16666 port on the router.
The Mobility Services Engine (MSE) is a platform that provides various services, such as location tracking, context-aware services, and analytics for wireless clients. The Cisco Wireless LAN Controller (WLC) is the central controller for the wireless network that manages and controls the access points (APs) and communicates with other devices, such as the MSE. The Network Mobility Services Protocol (NMSP) is a proprietary protocol used for communication between the Cisco WLC and MSE.
In this scenario, the MSE needs to be installed in a different network than the Cisco WLC. To allow communication between the WLC and MSE over NMSP, the UDP port 16666 or TCP port 16666 needs to be open. However, since UDP is a connectionless protocol and does not guarantee reliable delivery of data, TCP is preferred for NMSP communication.
Option A (Allow UDP/16113 port on the central switch) and Option C (Allow UDP/16666 port on the VPN router) are incorrect because they use UDP instead of TCP, and also because they specify the wrong port number (16113 instead of 16666).
Option B (Allow TCP/16113 port on the firewall) is also incorrect because it specifies the wrong port number (16113 instead of 16666).
Option D (Allow TCP/16666 port on the router) is the correct answer because it specifies the correct port number and uses TCP, which is the preferred protocol for NMSP communication. Therefore, the network engineer should configure the router to allow TCP traffic on port 16666 to enable communication between the WLC and MSE.
