• Question 162:

  What is the difference between the IEEE, the WiFi Alliance, and the FCC, ETSI, and TELEC?

  A. The IEEE and FCC are responsible for the standards that apply to wireless networks. The WiFi Alliance, ETSI, and TELEC are the governmental agencies that regulate compliance with local standards.
  B. The IEEE is responsible for Layer 1 and Layer 2 protocols. The WiFi Alliance is responsible for interoperability testing. The FCC, ETSI, and TELEC are responsible for radio frequency and transmission power-level regulations and standards in the U.S., Europe, and Japan.
  C. The IEEE is responsible for Layer 1 and Layer 2 protocols. The FCC, ETSI, and TELEC are responsible for interoperability testing and compliance. The WiFi Alliance is responsible for radio frequency and transmission power-level regulations and standards on a global basis.
  D. The IEEE and FCC are responsible for the Layer 3 protocol support and frequency and power-level regulations in the United States. ETSI and TELEC are responsible for frequency and power-level regulations in Europe and Japan. The WiFi Alliance is responsible to interoperability testing.
  B. The IEEE is responsible for Layer 1 and Layer 2 protocols. The WiFi Alliance is responsible for interoperability testing. The FCC, ETSI, and TELEC are responsible for radio frequency and transmission power-level regulations and standards in the U.S., Europe, and Japan.

  ---

  The FCC is the local regulatory authority responsible for frequency regulation in the United States. ETSI is a European standards organization responsible for producing standards for information and communications technologies. The Wi-Fi Alliance is an interoperability testing organization. The IEEE creates standards, and WPA is a pre-802.11 certification by the Wi-Fi Alliance.

• Question 163:

  In a network with a deployed Cisco WLC, which two entities must be configured with the shared secret key for 802.1X authentication? (Choose two.)

  A. WLC
  B. RADIUS server
  C. AP
  D. supplicant
  E. wireless client
  A. WLC
  B. RADIUS server

  ---

  The WLC needs to be configured in order to forward the user credentials to an external RADIUS server. The external RADIUS server then validates the user credentials and provides access to the wireless clients.

• Question 164:

  Which statement about ZigBee technology is true?

  A. It has low power consumption.
  B. It is designed only for point-to-point communications.
  C. It ranges up to 250 meters.
  D. It supports data rates up to 1 and 2 Mb/s.
  A. It has low power consumption.

  ---

  ZigBee is based on the IEEE 802.15.4 protocol for WPAN, and aims at developing hardware and applications with a low data rate but also low power consumption and low complexity -- for example, to control sensors. ZigBee-based products can access up to 16 separate 5 MHz channels in the 2.4 GHz band and are not compatible with 802.11 devices. The maximum power of ZigBee is 60 mW. Devices use low.

• Question 165:

  Refer to the exhibit.

  

  If Cisco WCS version 7.0 needs to have APs added, relocated, or removed on a respective map, which menu leads to the correct location to make that adjustment?

  A. Security
  B. Monitor
  C. Configure
  D. Services
  E. Administration
  F. Tools
  B. Monitor

  ---

  The Monitor menu provides you with a top-level description of the devices on your network. You can monitor your network, maps, Google Earth maps, various devices (controllers, access points, clients, tags, chokepoints, Wi-Fi TDOA receivers), RRM, alarms, and events.

• Question 166:

  Which two formats are supported for uploading background graphics to create a network map in Cisco WCS? (Choose two.)

  A. PNG
  B. JPEG
  C. DWG
  D. TIFF
  A. PNG
  B. JPEG

  ---

  Step 1 - Save the map in .PNG, .JPG, .JPEG, or .GIF format.

  Step 2 - Browse to and import the map from anywhere in your file system.

  Step 3 - Choose Monitor > Maps to display the Maps page.

  

  Step 4 - From the Select a command drop-down list, choose New Campus, and click Go.

  Step 5 - On the Maps > New Campus page, enter the campus name and campus contact name. Step 6 - Browse to and choose the image filename containing the map of the campus and click Open. Step 7 - Select the Maintain Aspect Ratio

  check box to prevent length and width distortion when WCS resizes the map.

  Step 8 - Enter the horizontal and vertical span of the map in feet.

  Step 9 - Click OK to add this campus map to the Cisco WCS database. WCS displays the Maps page, which lists maps in the database, map types, and campus status.

  Step 10 - (Optional) To assign location presence information, click the newly created campus link in the Monitor > Maps page.

• Question 167:

  Which statement about an infrastructure basic service set is true according to IEEE 802.11 specifications?

  A. The set also is called an ad hoc network.
  B. The BSSID is generated from the first wireless client that starts up in the IBSS.
  C. The set enables the use of ESS.
  D. No signals are relayed from one client to another client.
  C. The set enables the use of ESS.

  ---

  The set-up formed by the access point and the stations located within its coverage area are called the basic service set (or infrastructure basic service set, or BSS for short). Each BSS forms one cell.

  We can link several BSS's together (it means we link access points) using a connection called a distribution system in order to form an extended service set or ESS. The distribution system can also be a wired network, a cable between two

  access points or even a wireless network. Note: When a station moves from one access point to another in an ESS, it is called roaming.

• Question 168:

  The administrator needs to create a report that shows all controllers, APs, and Cisco 3300 Series MSEs in the WLAN, including hardware and software information. Which report includes this information?

  A. Device > Inventory
  B. Mesh > Nodes
  C. Network Summary > Executive Summary
  D. Network Summary > 802.11 Summary
  A. Device > Inventory

  ---

  In the left sidebar menu, all of the inventory report options are listed. These reports are generated based on the data already stored in the WCS database. Because inventory reports are not on-demand reports, some configuration changes may have occurred since the storage and may not duplicate the attributes of the controller that are reflected in the stored data. The choices are as follows:

  

  Access Point Inventory Report -- Provides data on deployed access points. The data that is returned includes but is not limited to the following: the access points' MAC address, model, location, and radio status.

  

  Combined Inventory Report -- Provides data on all deployed controllers, access points, and location appliances.

  

  Controller Inventory Report -- Provides data on deployed controllers. The data that is returned includes but is not limited to the following: the model, IP address, and serial number of the controller, what software version it is running, and where it is located. Location Server Inventory Report -- Provides data on deployed location appliances. The data that is returned includes but is not limited to the following: the IP address and version of the location appliance, which port is being used, and the time the appliance starts up.

• Question 169:

  Refer to the exhibit.

  

  Which syslog facility option is shown?

  A. an information field, which is added to every message that comes from the WLC
  B. a security feature, which is set on the syslog server
  C. the type of syslog server
  D. the Cisco WLC identifier for this syslog server
  A. an information field, which is added to every message that comes from the WLC

  ---

  A facility level is used to specify what type of program is logging a message. This lets the configuration file specify that messages from different facilities will be handled differently. Local7 maps to Facility level 23, which is local so the WLC will add this information to syslog messages when sending to the syslog server.

• Question 170:

  

  

  Option 43 is used to inform the DHCP client of the WLC AP-management IP address.

  

  Which four levels of messages will be sent to the logging server? (Choose four.)

  A. alerts
  B. critcal
  C. debugging
  D. emergencies
  E. errors
  F. informational
  G. notifications
  H. warnings
  A. alerts
  B. critcal
  D. emergencies
  E. errors

  ---

  There are a total of 8 logging severity levels. They are:

  

  We can see from the output that the severity level was set to Critical, which means that all messages level 3 and less will be sent.
