• Question 42:

  Instructions:

  1.

  THIS TASK DOES NOT REQUIRE DEVICE CONFIGURATION

  2.

  To access the multiple-choice questions, click on the numbered boxes on the left of the top panel.

  3.

  There is two multiple-choice question with this task. Be sure to answer the question before selecting the Next button

  Scenario:

  You are deploying a small wireless test network in a lab. The network is made up of a wireless LAN controller, a dual radio AP, and an iOS switch. You are testing the ability of wireless clients to access the network and are experiencing

  problems. Use the exhibits to resolve the issue.

  

  

  Old 2.4-GHz wireless laptops are unable to connect. What is the most likely cause of this problem?

  A. WLAN > General properties are incorrectly configured.
  B. WLAN > QoS properties are incorrectly configured.
  C. WLAN > Security properties are incorrectly configured.
  D. WLAN > Advanced properties are incorrectly configured.
  E. Wireless > AP > 802.11 b/g/n AP is incorrectly configured.
  F. Wireless > AP > 802.11 b/g/n > Network is incorrectly configured.
  F. Wireless > AP > 802.11 b/g/n > Network is incorrectly configured.

  Clientlink is not enabled and should be in a mixed client environment. Many networks still support a mix of 802.11a/g and 802.11n clients. Because 802.11a/g clients (legacy clients) operate at lower data rates, the older clients can reduce the capacity of the entire network. Cisco's ClientLink technology can help solve problems related to adoption of 802.11n in mixed-client networks by ensuring that 802.11a/g clients operate at the best possible rates, especially when they are near cell boundaries.

• Question 43:

  An enterprise needs their iPhones to connect to the EAP-TLS network. How should the devices be configured?

  A. Configure directly through the Settings application.
  B. Download the certificate from the web page then configure through the Settings application.
  C. Push the profile and certificate through Configuration Utility.
  D. Push the profile and certificate through iTunes.
  C. Push the profile and certificate through Configuration Utility.

• Question 44:

  Configurations are commonly uploaded and downloaded to a WLC. Which options are other examples of a file that can be uploaded from a Cisco 2500 Series WLC?

  A. packet capture
  B. crash file
  C. code
  D. login banner
  E. PAC
  B. crash file

  From Management > Tech Support, you can access useful information, such as controller crash files or AP crash logs (which logs the reasons for the crash). These files are usually transmitted to advanced tech support or TAC but usually not managed directly by Wireless CCNAs. Then, from the Command > Upload page in the web interface, you can upload the configuration file or other system files (event logs, message logs, trap logs, crash file, debug file, wireless attack signatures file, etc.

• Question 45:

  Which option describes computer-to-computer wireless communication?

  A. BSS and BSA
  B. IBSS and ad hoc network
  C. ad hoc network and BSA
  D. IBSS and ESS
  E. ESS and BSA
  F. BSS and ad hoc network
  B. IBSS and ad hoc network

  Ad-hoc mode is an 802.11 networking framework in which devices or stations communicate directly with each other, without the use of an access point (AP). Ad-hoc mode is also referred to as peer-to-peer mode or an Independent Basic Service Set (IBSS). Ad-hoc mode is useful for establishing a network where wireless infrastructure does not exist or where services are not required. http://www.webopedia.com/TERM/A/ad_hoc_mode.html

• Question 46:

  Which wireless client attempts to authenticate by using 802.1X?

  A. supplicant
  B. authenticator
  C. EAP
  D. RADIUS
  A. supplicant

  ---

  802.1x is an Institute of Electrical and Electronics Engineers (IEEE) standard that provides an authentication framework for WLANs. 802.1x uses the Extensible Authentication Protocol (EAP) to exchange messages during the authentication process. The authentication protocols that operate inside the 802.1x framework that are suitable for wireless networks include EAP-Transport Layer Security (EAP-TLS), Protected EAP (PEAP), and EAP-Tunneled TLS (EAP-TTLS). These protocols allow the network to authenticate the client while also allowing the client to authenticate the network. 802.1x authentication consists of three components: http://www.arubanetworks.com/techdocs/ArubaOS_60/UserGuide/802.1x.php

• Question 47:

  Refer to the exhibit.

  

  Which type of antenna does the H-plane pattern show?

  A. vertically polarized sector
  B. dipole
  C. diversity patch
  D. directional dish
  D. directional dish

• Question 48:

  Due to the terrain, a deployment requires a point-to-point wireless bridge to allow for network connectivity to a remote building. What 5GHz band would permitted to use the highest power in the U.S.?

  A. U-NII-3
  B. U-NII-2 Extended
  C. U-NII-2
  D. U-NII-1
  A. U-NII-3
