An Organization Wants to Deploy a WLAN Infrastructure That Provides

An organization wants to deploy a WLAN infrastructure that provides connectivity to these client categories: Employees Contractors Guest users Corporate IoT legacy devices that support no authentication or encryption Employees and contractors must authenticate with company credentials and get network access based on AD group membership. Guest users are required to authenticate with captive portal using predefined credentials. Only employees will run L2 encryption. Which implementation plan fulfills the requirements while maximizing the channel usage?

A) Create VAP1 to run WPA2-AES and 802.1x authentication, VAP2 to run opensystem encryption with MAC authentication, and VAP3 to run opensystem with captive portal.
B) Create VAP1 to run WPA2-AES and 802.1x authentication, VAP2 to run opensystem encryption with MAC authentication, and VAP3 to run opensystem with captive portal and L2 fail through.
C) Create a single VAP to run WPA2-AES and 802.1x authentication, MAC authentication L2 fail through, captive portal, and VIA support.
D) Create VAP1 to run WPA2-AES and 802.1x authentication, and VAP2 to run opensystem encryption with MAC authentication and captive portal.
