When selecting a centralized WLAN architecture, what new problem may arise when you change the data forwarding model from centralized to distributed?

• A.APs that were designed for a centralized forwarding model may not support all features in distributed forwarding mode.
• B.The router between the APs and the controller must be made aware of the APs as forwarding client STAs.
• C.All RRM controls will also need to be distributed to a master AP that acts as a channel and transmit power arbiter for other APs in the ESS.
• D.Centralized control functions, such as key management and distribution, RRM, and load balancing will no longer be supported.

After deploying a 5 GHz-only WLAN infrastructure in the USA, using 20 MHz channel widths and all 25 available channels, a manager tests the Guest SSID on his 802.11n tablet. During testing, he experiences several areas with poor RSSI (below -80 dBm) or no signal at all. Upon checking, all APs are operational, and coverage was validated post-deployment. What is the likely cause of this issue?

• A.His tablet doesn't support the 5 GHz band
• B.His tablet only supports a 40 MHz channel-width
• C.His tablet does not support one or more of the 5 GHz channels
• D.His tablet doesn't support MU-MIMO
