200-301 Question 23
Single answerA network engineer is deploying a centralized wireless network using a Wireless LAN Controller (WLC). The engineer wants to ensure that all access points (APs) in the network can be managed and configured centrally through the WLC. Which protocol must the APs use to establish communication with the WLC?
- A
CAPWAP
- B
BGP
- C
OSPF
- D
EIGRP
Show answer and explanation
Correct answer: A
Explanation
In centralized wireless networks, CAPWAP is the protocol used for communication between Wireless LAN Controllers (WLCs) and Access Points (APs). CAPWAP facilitates the management, configuration, and control of APs from a centralized WLC, making it essential for this type of deployment. The other protocols (BGP, OSPF, and EIGRP) are routing protocols and are not related to WLC-AP communication.
- A. Correct.
CAPWAP (Control and Provisioning of Wireless Access Points) is a protocol specifically designed for communication between Wireless LAN Controllers (WLCs) and Access Points (APs). It is the correct choice in this scenario.
- B. Incorrect.
BGP (Border Gateway Protocol) is used for exchanging routing information between different autonomous systems, not for managing APs in a wireless network.
- C. Incorrect.
OSPF (Open Shortest Path First) is a routing protocol used for determining the best path for data within an autonomous system, not for communication between WLCs and APs.
- D. Incorrect.
EIGRP (Enhanced Interior Gateway Routing Protocol) is a Cisco-specific routing protocol used for routing within an autonomous system and is not relevant for WLC-AP communication.
