Question

What does the term "spirt MAC" refer to in a wireless architecture?

Options

Adivides data link layer functions between the AP and WLC
Bcombines the management and control functions from the data-forwarding functions
Cuses different MAC addresses for 2.4 GHz and 5 GHz bands on the same AP
Dleverages two APs to handle control and data traffic

Explanation

In a split MAC architecture, the functions of the MAC layer (Media Access Control layer, part of the data link layer) are divided between the Access Point (AP) and the Wireless LAN Controller (WLC). The AP handles real-time functions like beaconing, responding to probe requests, and packet The WLC manages higher-level control functions like authentication, association, and mobility This division allows for more efficient management of wireless networks, where the WLC can centralize control and the AP focuses on fast, real-time operations.
