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

• A.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.
• B.APs that were designed for a centralized forwarding model may not support all features in distributed forwarding mode.
• C.The router between the APs and the controller must be made aware of the APs as forwarding client STAs.
• D.Centralized control functions, such as key management and distribution, RRM, and load balancing will no longer be supported.

You are tasked with designing the WLAN to accommodate certain high density areas on your university campus where users frequently come and go. With a limited DHCP pool size (subnet mask = 255.255.252.0) for this WLAN subnet, you want to ensure that your DHCP addresses are used efficiently and are not exhausted, which would prevent new client Layer 3 connections. The DHCP server is a Windows Server 2012 R2 machine.
Your design task is to determine the best configuration to allow as many users as possible while avoiding WLAN service interruptions and also to use the available addresses as efficiently as possible.
What setting would be most effective at achieving this design task?

• A.Set the RTS threshold to 2346 bytes
• B.Set the DHCP lease for this pool to 20 minutes
• C.Set the inactive wireless client timeout (client age-out) to 5 minutes
• D.Set the maximum client limit per radio to 64

What is the purpose of DHCP Option 43, and how is it used with WLANs?

• A.It provides clients with a temporary IP address on a restricted VLAN until 802.1X authentication is completed. Then the client receives its long-term IP address.
• B.It provides IP address bindings for specific network nodes that require long-term IP address assignments. WLAN controllers are configured to use Option 43 to receive long-term IP address leases that are centrally managed with DHCP.
• C.It supports vendor-specific IP address attributes for node discovery purposes. APs use Option 43 with vendor class identifiers to obtain the IP address of a centralized WLAN controller.
• D.It integrates a DHCP server with AAA servers and user databases to dynamically assign IP addresses to client devices. During 802.1X, the AAA server uses
