Cisco 640-722 Online Questions & Answers

• Question 11:

  A network engineer in the GUI of WCS version 7 wants to add an access point to a map. Where can this command be found within the drop-down menu?

  A. Monitor > Maps
  B. Reports > Maps
  C. Monitor > Network Summary
  D. Configure > Maps
  A. Monitor > Maps

  ---

  The physical location of the client (such as building, floor, and so on). Clicking the map location displays information in the Monitor > Maps page. Reference: http://www.cisco.com/c/en/us/td/docs/wireless/wcs/7-0/configuration/guide/WCS70cg/7_0clientmgmt.html

• Question 12:

  Which path do you take to manage the results of a report that had been run on network utilization?

  A. Reports > Report Launch Pad > Device > Utilization
  B. Reports > Report Launch Pad > Scheduled Run Results
  C. Reports > Saved Reports > Scheduled Run Results
  D. Reports > Scheduled Run Results
  D. Reports > Scheduled Run Results

  ---

  There are five menus on each window: Monitor, Reports, Configure, Location, Administration, and Help. When you move the mouse over any of the menus, a drop-down menu appears.

• Question 13:

  What protocol overcomes the weaknesses of LEAP?

  A. EAP-TLS
  B. PEAP
  C. EAP-FAST
  D. EAP-TTLS
  C. EAP-FAST

• Question 14:

  A lightweight AP has been deployed in local mode in a network that consists of 10 wireless LAN controllers in a single mobility group. The AP has been configured to use primary, secondary, and tertiary Cisco WLCs. Due to a major power failure, all those Cisco WLCs are unavailable.

  Which step does the AP take next?

  A. The AP reboots and repeatedly attempts to join the configured primary, secondary, and tertiary Cisco WLCs in that order. The process continues until one of the configured Cisco WLCs is available.
  B. The AP attempts to join a Cisco WLC configured as a master controller.
  C. The AP attempts to join the Cisco WLC that has the greatest capacity available.
  D. The AP state transitions to AP Fallback Mode and continues to provide limited WLAN services (that is, no new client authentications) until a Cisco WLC is available.
  B. The AP attempts to join a Cisco WLC configured as a master controller.

  ---

  1. The LAP looks at the Master Controller flag field in the LWAPP discovery responses from the candidate WLCs if one of these items is true:

  

  No primary, secondary, and/or tertiary controllers have been configured for an AP.

  

  These controllers cannot be found in the candidate list.

  

  The LWAPP joins to those controllers have failed.

  If a WLC is configured as a Master Controller, the LAP selects that WLC and sends it an LWAPP join request.

• Question 15:

  What tool can be used to increase accuracy of WCS heat maps?

  A. Map Editor
  B. Planning Tool
  C. CleanAir
  D. Cisco Spectrum Expert
  A. Map Editor

• Question 16:

  You are about to use a hotel's guest wireless services using a wireless laptop. Which three items do you need to establish a wireless connection? (Choose three.)

  A. SSID name
  B. RF channel
  C. RF signal
  D. 802.1X/EAP credentials
  E. pre-shared key
  F. web page
  G. WPA/WPA2 settings
  A. SSID name
  C. RF signal
  F. web page

  ---

  Another common authentication method, especially for guest networks (for example, in hotels, where Internet access must be simple, requiring only an SSID with decent RF signal in each room and a web page to authenticate the user, regardless of the underlying operating system), is Web authentication.

• Question 17:

  Which Cisco AnyConnect module allows you to set the parameters that are needed to connect to the wireless network?

  A. NAM
  B. DART
  C. posture
  D. telemetry
  A. NAM

  ---

  The main components used in IUWNE are the Cisco AnyConnect Mobility Client itself, associated with the Network Access Module (NAM) used to manage existing profiles and provide the wireless connectivity. You also can click Advanced to open the NAM front end. You can then manage profiles (create, delete, reorder). The network administrator can restrict the types of networks that the end user can manipulate on the NAM.

• Question 18:

  Refer to the exhibit.

  

  Which tool is shown?

  A. Cisco WCS client troubleshooting tool
  B. Cisco WLC client troubleshooting tool
  C. WLAN Client Debug Analyzer
  D. Cisco WLAN Connection Advisor
  A. Cisco WCS client troubleshooting tool

• Question 19:

  Which two statements about the requirements to configure inter-controller roaming are true? (Choose two.)

  A. The same mobility domain names are configured across controllers.
  B. The same RF group names are configured across controllers.
  C. The same controller hardware version is configured across controllers.
  D. The same AP manager interface is configured across controllers.
  E. The same virtual interface is configured across controllers.
  F. The same controller software version is configured across controllers.
  A. The same mobility domain names are configured across controllers.
  E. The same virtual interface is configured across controllers.

  ---

  All controllers must be configured with the same mobility group name.

  All controllers must be configured with the same virtual interface IP address.

  If necessary, you can change the virtual interface IP address by editing the virtual interface name on the Controller > Interfaces page. If all the controllers within a mobility group are not using the same virtual interface, inter- controller roaming

  may appear to work, but the handoff does not complete, and the client loses connectivity for a period of time.

• Question 20:

  The IEEE 802.11n standard provides 40-MHz channels, improved MAC efficiency, and MIMO. Which three elements define the 802.11n implementation of MIMO? (Choose three.)

  A. channel bonding
  B. dynamic frequency selection
  C. maximal ratio combining
  D. packet aggregation
  E. spatial multiplexing
  F. transmit beam forming
  C. maximal ratio combining
  E. spatial multiplexing
  F. transmit beam forming

  ---

  Maximal ratio combining (MRC) is typically used on all 802.11n access points. Transmit beam forming is used to increase the gain towards the client. For 802.11n clients, spatial multiplexing is used to deliver enhanced high throughput data rates upwards of 300 Mbps
