  • 2. 

    Which of the following is not a functional area of the Cisco Unified Wireless Net- work?

    • A.

      AP

    • B.

      Controller

    • C.

      Client

    • D.

      ACS

    Correct Answer
    D. ACS
    Explanation
    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.

  • 3. 

    Of all the Cisco Wireless LAN Controllers, what is the greatest number of APs you can support?

    • A.

      Up to 50

    • B.

      Up to 150

    • C.

      Up to 300

    • D.

      Up ton 30,000

    Correct Answer
    C. Up to 300
    Explanation
    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.

    Rate this question:

  • 4. 

    What protocol is used for communication between an AP and a WLC?

    • A.

      STP

    • B.

      LWAPP

    • C.

      LDAP

    • D.

      TCP

    Correct Answer
    B. LWAPP
    Explanation
    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.

    Which of the following functions does the controller handle? (Choose all that apply.)

    • A.

      Association

    • B.

      Reassociation when you have clients that are roaming

    • C.

      The authentication process

    Correct Answer(s)
    A. Association
    B. Reassociation when you have clients that are roaming
    C. The authentication process
    Explanation
    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.

      Frame bridging

    • C.

      Send responses to probe requests from different clients on the network

    • D.

      Forward notifications of received probe requests to the controller

    Correct Answer(s)
    A. Buffer and transmit the frames for clients that are in power-save mode
    C. Send responses to probe requests from different clients on the network
    D. Forward notifications of received probe requests to the controller
    Explanation
    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.

  • 11. 

    When an AP operates in H-REAP mode, where would it be seen?

    • A.

      In a campus

    • B.

      At the remote edge of a WAN

    • C.

      In the data center

    • D.

      Bridging site-to- site 

    Correct Answer
    B. At the remote edge of a WAN
    Explanation
    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.

    True or false: An AP must run the same version of code as the controller.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    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.
