Question

question 10

which protocol is typically used by cisco wireless controllers to communicate with access points?

a snmp
b ftp
c lwapp
d http

Explanation:

Identify the core question

The question asks for the protocol typically used by Cisco wireless LAN controllers (WLCs) to communicate with lightweight access points (APs).

Analyze the given options

• A. SNMP (Simple Network Management Protocol): Used for network management and monitoring, not for direct control/data tunneling between WLCs and APs.
• B. FTP (File Transfer Protocol): Used for transferring files, not for real-time AP-to-controller communication.
• C. LWAPP (Lightweight Access Point Protocol): A Cisco-developed protocol designed specifically for communication, configuration, and management between a WLC and lightweight APs.
• D. HTTP (Hypertext Transfer Protocol): Used for web traffic and web-based management interfaces, not for AP-to-controller tunneling.

Determine the correct protocol

LWAPP (and its standard successor CAPWAP) is the protocol used by Cisco wireless controllers to manage and communicate with lightweight access points. Therefore, LWAPP is the correct choice.

Answer:

• (A) SNMP
• (B) FTP
• (C) LWAPP (Correct answer)
• (D) HTTP
