  A. Defined DSSS and FHSS as possible methods for modulation
  B. Designed to operate in the 5 GHz ISM frequency spectrum
  C. The most common deployment is three non-overlapping channels that are 20 MHz wide

  E. Defined FHSS and OFDM as possible methods for modulation
  F. The most common deployment is three non-overlapping channels that are 22 MHz wide
  G. Designed to operate in the2.4 GHz ISM frequency spectrum
  H. The protocol sets the maximum throughput at1 Mb/s
  A. Defined DSSS and FHSS as possible methods for modulation
  C. The most common deployment is three non-overlapping channels that are 20 MHz wide
  D. The protocol sets the maximum throughput at 1 Mb/s or 2 Mb/s
  G. Designed to operate in the2.4 GHz ISM frequency spectrum

  FHSS is still described in the original 802.11 protocol, but another technique was preferred and adopted by all 802.11 networks: Direct Sequence Spread Spectrum. Instead of small channels and a jumping sequence, the information is sent over a wider channel. This channel is 22 MHz wide (if the center frequency is 2.412, this channel spans from 2.401 GHz to 2.423 GHz) and does not move (no hopping, which is why the sequence is said to be direct instead of hopping). Then, over this 22 MHz channel, several bits of information are sent in parallel. If a source of interference affects part of the channel, it will prevent only the bits sent in that frequency from reaching the receiver.

• Question 314:

  Which Cisco program for WLAN client vendors helps to ensure that their devices are interoperable with Cisco WLAN infrastructure?

  A. CCX
  B. CCMP
  C. ASDM
  D. WLSE
  A. CCX

  IEEE and industry standards define how a Wi-Fi radio interoperates with a wireless LAN infrastructure, and the Wi-Fi CERTIFIEDTM seal ensures interoperability. For many organizations that rely on mobile computers, however, Wi-Fi CERTIFIED is not enough. These organizations need assurance that their mobile computers will interoperate with a Cisco wireless LAN infrastructure and support Cisco wireless LAN innovations for enhanced security, mobility, quality of service, and network management. The Cisco Compatible seal gives organizations the assurance that they seek.

  A mobile computer earns the Cisco Compatible seal through a program called Cisco Compatible Extensions, or CCX. Like the Wi-Fi certification program, CCX:

  The CCX specification is a superset of that used for Wi-Fi certification. In fact, a device cannot be certified for CCX unless it, or the Wi-Fi radio inside it, is Wi-Fi CERTIFIED. http://www.digikey.com/Web%20Export/Supplier%20Content/ Laird_776/PDF/laird-wireless-value-cisco-compatible-extenstion.pdf?redirected=1

• Question 315:

  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 316:

  Microsoft Active Directory integrated machines are not authenticating to the internal WLAN. The WLAN settings are WPA2-AES-802.1x and are authenticating to a Cisco Identity Services Engine server. You investigate and note that non-domain authenticated machines are properly authenticating to the WLAN using their Active Directory credentials. Why would this problem occur?

  A. The WLAN is configured improperly in group policy.
  B. The ISE server is not joined to the domain, causing authentications to fail.
  C. The domain machines are configured to disable the wireless adapter.
  D. The non-domain machines are using local accounts that are not authenticated through the domain.
  A. The WLAN is configured improperly in group policy.

• Question 317:

  During Layer 2 intercontroller roaming, which two items change? (Choose two.)

  A. SSID
  B. VLAN
  C. IP address
  D. AP
  E. controller
  D. AP
  E. controller

  ---

  When the client associates to an access point joined to a new controller, the new controller exchanges mobility messages with the original controller, and the client database entry is moved to the new controller. New security context and associations are established if necessary, and the client database entry is updated for the new access point. This process remains transparent to the user. http://www.cisco.com/c/en/us/td/docs/wireless/controller/7-0/configuration/guide/c70/c70mobil.html

• Question 318:

  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

  Select and Place:

  

  

• Question 320:

  Which three items do you need to establish a wireless connection to an enterprise wireless network? (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
  D. 802.1X/EAP credentials

  Most clients enable you to associate to a detected network (broadcasted SSID) or configure a specific profile. In all cases, you must configure the network name (SSID), the operating mode (ad-hoc or infrastructure), and some security settings (that will be different depending on whether the SSID uses Pre-Shared Key Security or Enterprise [EAP/802.1x] security).
