Cisco 640-722 Online Questions & Answers

• Question 121:

  You have a small organization with multiple Cisco WCS servers. Management has become cumbersome and you are planning to deploy Cisco WCS Navigator.

  When the Cisco WCS Navigator has been deployed, how are the existing Cisco WCS servers added to the Cisco WCS Navigator, which software versions are supported, and which protocol(s) do they use to communicate with Navigator?

  A. Cisco WCS Navigator searches the enterprise intranet to locate the existing Cisco WCS servers and adds them automatically using SOAP as long as there is only a difference of one version or less between Cisco WCS and WCS Navigator.
  B. Each existing Cisco WCS server must be added manually and use SOAP/HTTP to communicate with the Cisco WCS Navigator platform as long as the software versions of Cisco WCS and Cisco WCS Navigator are the same.
  C. Cisco WCS must be on the same software version as Cisco WCS Navigator and each Cisco WCS server is added automatically using XML over HTTP.
  D. When Cisco WCS Navigator is added, all the Cisco WCS servers must be added manually, each system must use the same software release as Navigator, and the Cisco WCS communicates with Cisco WCS Navigator by using SOAP/ XML over HTTPS.
  D. When Cisco WCS Navigator is added, all the Cisco WCS servers must be added manually, each system must use the same software release as Navigator, and the Cisco WCS communicates with Cisco WCS Navigator by using SOAP/ XML over HTTPS.

• Question 122:

  What are three characteristics of WCS? (Choose three.)

  A. based on a single server licensing system
  B. used for wireless planning
  C. used for real-time tracking of multiple clients
  D. used for wireless management
  E. used for RF fingerprinting
  F. based on a per server licensing system
  A. based on a single server licensing system
  B. used for wireless planning
  D. used for wireless management

• Question 123:

  

  

  

  

  All equipment is operational. Through which two methods can a wireless client receive an IP address when associating to the WLAN? (Choose two.)

  A. The clients can receive an IP address from SW1.
  B. Tie clients can receive an IP address from WLC1.
  C. The clients will not receive an IP address from either DHCP server because of overlapping address ranges.
  D. The clients can receive an IP address in a round-robin manner from either SW1 or WLC1.
  E. The clients can use a static IP address.
  B. Tie clients can receive an IP address from WLC1.
  E. The clients can use a static IP address.

  ---

  As shown below, the DHCP server functionality has been enabled on the WLC1. Aside from DHCP, all clients can always statically assign themselves an IP address.

  

• Question 124:

  You are designing a wireless network in a medical facility. Which three areas are bad locations in which to install a wireless access point? (Choose three.)

  A. in front of the elevators doors
  B. in the hallways
  C. next to the electrical room
  D. inside offices
  E. near medical imaging devices
  F. in the lobby
  A. in front of the elevators doors
  C. next to the electrical room
  E. near medical imaging devices

  ---

  You should not install access points in areas where interference from outside devices can occur. A great deal of electrical interference can occur near the electrical room and near medical imaging devices. Also, because elevators often have metal doors and the shafts are often concrete or contain other materials that degrade Wi-Fi coverage, it is best to avoid them.

• Question 125:

  The administrator has noticed that the configuration on a controller is different than in Cisco WCS. How can the administrator fix this issue?

  A. The configuration can be copied from the controller to the Cisco WCS or from the WCS to the controller.
  B. The configuration can be copied only from the Cisco WCS to the controller.
  C. The configuration can be copied only from the controller to the Cisco WCS.
  D. The controller must be removed from the Cisco WCS and then added again.
  A. The configuration can be copied from the controller to the Cisco WCS or from the WCS to the controller.

  ---

  The Copy and Replace AP feature is useful if you need to remove an access point from the network and replace it with a new access point. All of the access point information, such as AP mode, name, and map location needs to be copied from the old access point to the new access point.

• Question 126:

  Which two statements about the Cisco WLC and AP code upgrade when 7.0 is running are true? (Choose two.)

  A. The AP can download and run new code only after a Cisco WLC reboot causes the AP discovery and join.
  B. The AP can download new code before the Cisco WLC reboot, but only if the AP is configured the CLI via SSH.
  C. The AP can download new code before Cisco WLC reboot if it is configuring the Cisco WLC directly using the GUI via HTTP or HTTPS.
  D. The Cisco WLC defaults to booting newer code, but it can boot older backup code only from the CLI configuration.
  E. The Cisco WLC can boot either primary or backup code configured from the GUI.
  F. The Cisco WLC can download only a single code at a time for reboot.
  C. The AP can download new code before Cisco WLC reboot if it is configuring the Cisco WLC directly using the GUI via HTTP or HTTPS.
  E. The Cisco WLC can boot either primary or backup code configured from the GUI.

  ---

  Each Cisco WLC can boot off the primary, last-loaded OS image or boot off the backup, earlier- loaded OS image. In order to change a Cisco WLC boot option, issue the config boot command. By default, the primary image on the controller

  will be chosen as the active image.

  Examples

  > config boot primary

  > config boot backup

  In order to configure the boot order using the WLC GUI, complete these steps:

  From the WLC GUI, navigate to the Commands page.

  From the Commands on the left, click Config Boot. The Config Boot Image page appears.

  

  This page displays the Primary and Backup images presently available on the controller, and also indicates the Active image. In order to change the Active image, select the desired image from the image drop-down menu and click Apply.

  

  In this example, Backup is selected.

  Save the configuration and reboot.

  When the WLC reboots and comes back up, it will boot with the backup image.

• Question 127:

  You have brought your MacBook Pro running OS 10.6 to work and intend use the enterprise wireless network. This network is using EAP-FAST and 2.4 GHz for data and 5 GHz for VoWLAN.

  Which statement about the laptop configuration and wireless connection is true?

  A. Install a USB wireless adapter and configure
  B. Install Apple EAP-Fast plug-in and configure
  C. Install Cisco AnyConnect v2.4 and configure
  D. Configure Apple network preferences for EAP-FAST
  E. The laptop does not support EAP-FAST and will be unable to connect
  F. The laptop only supports 5 GHz and will be unable to connect
  D. Configure Apple network preferences for EAP-FAST

  ---

  MacBook Pro using 10.6 supports 2.4Ghz only, so the EAP-FAST should be used. 5Ghz support was added to MacBook later.

• Question 128:

  Which two Cisco WLC management-access methods are available as the default setting? (Choose two.)

  A. SSH
  B. HTTPS
  C. Telnet
  D. HTTP
  A. SSH
  B. HTTPS

  ---

  The less secure methods of telnet and SSH are disabled by default and need to be manually configured. Only SSH and HTTPS are enabled by default.

• Question 129:

  Which information on the Monitoring page of a Cisco WLC verifies that the wireless network is operational?

  A. In the Access Point Summary section, the All APs number in the Up column is the same as in the Total column.
  B. In the Client Summary section, the Current Clients number is positive.
  C. In the Controller Summary section, the 802.11b/g Network State is shown as Enabled.
  D. In the Controller Summary section, the CPU Usage number is positive.
  A. In the Access Point Summary section, the All APs number in the Up column is the same as in the Total column.

  ---

  The output from the access point summary section of the Cisco WLC can be seen at the reference link below:

• Question 130:

  What are the interface statuses of a lightweight AP working in rogue-detection mode?

  A. radios turned off, Ethernet interface up
  B. radios and Ethernet interfaces up
  C. radios turned on, Ethernet interface shut down
  D. radios turned on, Ethernet interface status controlled by Cisco WLC
  A. radios turned off, Ethernet interface up

  ---

  In this mode, the AP radio is turned off, and the AP listens to wired traffic only. The controller passes the APs configured as rogue detectors as well as lists of suspected rogue clients and AP MAC addresses. The rogue detector listens for ARP packets only, and can be connected to all broadcast domains through a trunk link if desired.
