CISCO Wireless Network Architecture

A controller manages a Lightweight AP.

An AP must run the same version of code as the controller in order to ensure compatibility and proper functioning of the wireless network. This is because the AP relies on the controller for configuration, management, and communication. If the AP and the controller are running different versions of code, it may lead to inconsistencies, errors, and potential compatibility issues. Therefore, it is important to keep the AP and the controller on the same software version to maintain a stable and efficient wireless network.

LWAPP stands for Lightweight Access Point Protocol, which is used for communication between an Access Point (AP) and a Wireless LAN Controller (WLC). This protocol allows the AP to establish a secure connection with the WLC, enabling centralized management and control of the wireless network. LWAPP provides features like configuration synchronization, firmware updates, and mobility management, making it an essential protocol for efficient and seamless communication between APs and WLCs.

The correct answer is ACS. ACS stands for Access Control Server, which is not a functional area of the Cisco Unified Wireless Network. The other options, AP (Access Point), Controller, and Client, are all functional areas of the network. The Access Point is responsible for connecting wireless devices to the network, the Controller manages and controls the Access Points, and the Client refers to the wireless devices themselves. ACS, on the other hand, is a separate server used for authentication, authorization, and accounting purposes in network access control.

When an AP operates in H-REAP mode, it would be seen at the remote edge of a WAN. H-REAP stands for Hybrid Remote Edge Access Point, and it is a feature in Cisco wireless networks that allows access points to function in a distributed manner. In H-REAP mode, the access point can locally switch and tunnel traffic, providing connectivity to wireless clients even if the connection to the centralized controller is lost. This makes it ideal for remote locations or branches where a WAN connection is required. Therefore, the correct answer is at the remote edge of a WAN.

The correct answer is "Up to 300". This means that out of all the Cisco Wireless LAN Controllers available, the maximum number of Access Points (APs) that can be supported is 300. This suggests that the controller has the capacity and capability to handle and manage up to 300 APs in a wireless network.

The Cisco WiSM can manage up to 300 APs. This means that it has the capability to control and monitor the operations of 300 Access Points simultaneously. This is a significant number and allows for efficient management of a large wireless network.

The Cisco WiSM can manage up to 300 APs.

An AP, or Access Point, typically handles 16 VLANs. VLANs, or Virtual Local Area Networks, are used to segment a network into multiple virtual networks, allowing for better network management and security. By supporting 16 VLANs, an AP can provide flexibility in network configuration and accommodate different user groups or departments within an organization.

The CUWN architecture comprises 5 elements.

The 1250 series AP supports the 802.11n draft version 2.0.

The AP handles buffering and transmitting frames for clients that are in power-save mode, sending responses to probe requests from different clients on the network, and forwarding notifications of received probe requests to the controller.

The controller handles the functions of Association, Reassociation when clients are roaming, and the authentication process. These functions involve the controller facilitating the connection and communication between clients and the network. The controller is responsible for managing the association and reassociation of clients, especially when they are moving between different access points. Additionally, the controller handles the authentication process, ensuring that clients are authorized to access the network.

The 1130AG and 1240AG APs support 802.11a/b and g.

The 4400 series WLC, model AIR-WLC4404-100-K9, can support up to 100 APs. This means that it has the capacity to manage and control the connectivity of 100 Access Points simultaneously. This is an important specification to consider when planning for the deployment of wireless access points in a network.

A Location Appliance is used to track more than one device at a time in wireless network management.

In a mobility domain, the number of lightweight APs that can be supported is determined by the maximum number of APs that the controller can manage. The correct answer of 7200 suggests that in this particular scenario, the mobility domain can support up to 7200 lightweight APs.
