  A. an AP tied to a pole that is used for active surveys
  B. an AP connected to the wired network with a single cable
  C. an AP with a single antenna and multiple spatial streams
  D. an AP that is used to switch packets between SSIDs
  D. an AP that is used to switch packets between SSIDs

• Question 52:

  A wireless engineer is designing a network for the London branch of a company. Which 5-GHz band allows the branch to use the highest EIRP?

  A. 2.4-GHz ISM
  B. UNII-1
  C. UNII-2
  D. UNII-2 Extended
  D. UNII-2 Extended

• Question 53:

  In a typical wireless network using WPA, WPA2 or VPN, why is it still possible for a rogue client to launch a DOS attack?

  A. WPA and WPA2 are not considered strong encryption algorithms and are easily cracked.
  B. 802.11 management frames are easily compromised.
  C. Cisco Compatible Extensions v5 are required with WPA, WPA2, or VPN to keep rogues from launching attacks in the wireless network.
  D. The message integrity check frames are never encrypted or authenticated, which allows rogues to spoof clients.
  B. 802.11 management frames are easily compromised.

  A different receiver is needed for each 802.11a, b, g, and n radios, so using all simultaneously would severely impact the overall battery life of a mobile device.

• Question 54:

  You are testing a new autonomous Cisco Aironet 1260 AP that has booted for the first time on the existing corporate network, which includes voice, data, and location services. How do you reach the GUI of the AP?

  A. HTTP to 10.0.0.1.
  B. HTTP to 192.168.1.1.
  C. HTTP to the DHCP address.
  D. HTTPS to 10.0.0.1.
  E. HTTPS to the 192.168.1.1.
  F. HTTPS to the DHCP address.
  C. HTTP to the DHCP address.

  ---

  Make sure DHCP is enabled on the network or DNS resolution is available. The access point must receive its IP address through DHCP or DNS resolution, and the GUI can be accessed by using HTTP to this address. http://www.cisco.com/c/en/us/td/docs/wireless/access_point/1260/quick/guide/ap1260getstart.html

• Question 55:

  An engineer has just deployed a Cisco Aironet 3702 Access Point with an access layer switch that supports IEEE 802.1af Power over Ethernet. How will the access points react to the wattage that is available in 802.1af?

  A. disable the BVI interface
  B. fail to boot in CAPWAP mode
  C. operate in 3x3 MIMO mode
  D. enable the 2.4-GHz radios with 40-MHz channel bonding
  C. operate in 3x3 MIMO mode

• Question 56:

  In the current RF environment, the noise floor is -95 dBm. A tablet needs an SNR of 25 dB to transmit at the required speed. What must the RSSI cell edge be to meet the required SNR?

  A. -120 dBm
  B. -90 dBm
  C. -70 dBm
  D. -60 dBm
  E. -50 dBm
  C. -70 dBm

  B. foreign
  C. broadcasting
  D. SE-connect
  D. SE-connect

• Question 58:

  A. ISE Policy Services
  B. Prime Infrastructure
  C. ISE Monitoring
  D. Wireless Controller
  E. DHCP Server
  B. Prime Infrastructure
  C. ISE Monitoring

• Question 59:

  B. If a Cisco 5760 wireless controller is used, it acts as a mobility controller.
  C. If a Cisco 2504 wireless controller is used, it acts as a mobility agent.
  D. One or more discrete controllers must be used to support the desired access point count.
  E. If a Cisco 5508 wireless controller is used, it acts as a mobility controller.
  F. If a Cisco 5760 wireless controller is used, it acts as a mobility controller and mobility agent.
  A. A single stack of Catalyst 3850 series switches can be used to support the desired access point count.
  B. If a Cisco 5760 wireless controller is used, it acts as a mobility controller.
  D. One or more discrete controllers must be used to support the desired access point count.
