An engineer is configuring multicast for two WLCs.
The controllers are in different physical locations and each handles around 500 wireless clients.
How should the CAPWAP multicast group address be assigned during configuration?

A. B. C. D.D.
In a wireless LAN environment, the Wireless LAN Controllers (WLCs) are responsible for managing and controlling the access points (APs) and wireless clients. To support multicast traffic, WLCs use the Control and Provisioning of Wireless Access Points (CAPWAP) protocol, which allows the APs to join the WLCs and receive configuration information.
When configuring multicast for multiple WLCs in different physical locations, it's important to assign a unique CAPWAP multicast group address to each WLC. This ensures that the multicast traffic is sent only to the specific WLC that needs to receive it.
Option A ("Each WLC must be assigned a unique multicast group address") is therefore the correct answer. This approach allows for efficient use of network resources and minimizes unnecessary multicast traffic.
Option B ("Each WLC management address must be in the same multicast group") is not a recommended approach because it would result in all WLCs receiving the same multicast traffic, regardless of whether or not they need it. This could lead to network congestion and performance issues.
Option C ("Both WLCs must be assigned the same multicast group address") is also not recommended because it could result in multicast traffic being sent to both WLCs, even if one of them doesn't need it. This could also lead to network congestion and performance issues.
Option D ("Each WLC management address must be in a different multicast group") is not recommended because it would result in the multicast traffic being sent to the WLC management addresses, which may not be the most efficient way to handle multicast traffic in a wireless LAN environment.
