  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 to access the network and are experiencing problems.

  Use the exhibits to resolve the issues.

  

  

  

  Tablets and other wireless clients are unable to connect at any 802.11 n data rates. 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 a/n is incorrectly configured.
  F. Wireless > 802.11a/n > Network is incorrectly configured.
  C. WLAN > Security properties are incorrectly configured.
