• Question 132:

  What path displays the current maps within the WCS version 7 GUI?

  A. Monitor > Maps
  B. Reports > Maps
  C. Services > Maps
  D. Administration > Maps
  E. Configure > Maps
  F. Tools > 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 133:

  When Cisco AnyConnect modules are installed on a PC, which module must be installed first?

  A. telemetry
  B. web security
  C. VPN
  D. NAM
  E. DART
  F. posture
  G. CSSC
  C. VPN

  ---

  The VPN module is mandatory for all other modules to function correctly and must be installed first. Even if the VPN module is not selected for installation, it will be pushed and installed on the client.

• Question 134:

  What is Cisco WCS Navigator?

  A. a single point of management for multiple Cisco WCS servers
  B. a server for storing and reviewing Cisco Spectrum Expert station data
  C. a server for storing the location data of wireless clients
  D. a GUI for displaying the data of Cisco CleanAir APs, aligned with an uploaded map
  E. a single point of management for multiple Cisco WLC systems
  A. a single point of management for multiple Cisco WCS servers

  ---

  The Cisco WCS Navigator centralizes the operational control and management of multiple Cisco WCS management platforms. This easy-to-use platform delivers the following cross-system capabilities:

  

  Network monitoring

  

  Aggregated alarm notifications

  

  Automated browser redirect

  

  Simplified setup and configuration

  

  Quick and advanced searches

  

  Location tracking of client, Wi-Fi, and rogue devices Inventory reports

  

  Secure administrative access

• Question 135:

  What are three primary components that describe TKIP? (Choose three.)

  A. broadcast key rotation
  B. dynamic WEP
  C. message integrity check
  D. per-packet key hashing
  E. symmetric key cipher
  F. WPA2 enterprise mode
  A. broadcast key rotation
  C. message integrity check
  D. per-packet key hashing

  ---

  TKIP uses the same underlying mechanism as WEP, and consequently is vulnerable to a number of similar attacks. The message integrity check, per-packet key hashing, broadcast key rotation, and a sequence counter discourage many attacks. The key mixing function also eliminates the WEP key recovery attacks.

• Question 136:

  Which of the following are three functions of Cisco RRM? (Choose three.)

  A. TPC
  B. intercontroller roaming
  C. dynamic channel assignment
  D. intracontroller roaming
  E. coverage hole detection
  A. TPC
  C. dynamic channel assignment
  E. coverage hole detection

  ---

  RRM can periodically reconfigure the 802.11 RF network for best efficiency. To do this, RRM performs these functions:

  

  Radio resource monitoring

  

  Transmit power control

  

  Dynamic channel assignment

  

  Coverage hole detection and correction

• Question 137:

  What are three characteristics of the 802.11g standard? (Choose three.)

  A. speed of as much as 11 Mb/s
  B. speed of as much as 54 Mb/s
  C. backward-compatibility with 802.11a
  D. backward-compatibility with 802.11b
  E. OFDM as an additional modulation technique
  F. OFDM and CCK as additional modulation techniques
  B. speed of as much as 54 Mb/s
  D. backward-compatibility with 802.11b
  E. OFDM as an additional modulation technique

  ---

  802.11g is the third modulation standard for wireless LANs. It works in the 2.4 GHz band (like 802.11b) but operates at a maximum raw data rate of 54 Mbit/s. Using the CSMA/CA transmission scheme, 31.4 Mbit/s [1] is the maximum net throughput possible for packets of 1500 bytes in size and a 54 Mbit/s wireless rate (identical to 802.11a core, except for some additional legacy overhead for backward compatibility). In practice, access points may not have an ideal implementation and may therefore not be able to achieve even 31.4 Mbit/s throughput with 1500 byte packets. 1500 bytes is the usual limit for packets on the Internet and therefore a relevant size to benchmark against. Smaller packets give even lower theoretical throughput, down to 3 Mbit/s using 54 Mbit/s rate and 64 byte packets. Also, the available throughput is shared between all stations transmitting, including the AP so both downstream and upstream traffic is limited to a shared total of 31.4 Mbit/s using 1500 byte packets and 54 Mbit/s rate. 802.11g hardware is fully backwards compatible with 802.11b hardware. Details of making b and g work well together occupied much of the lingering technical process. In an 802.11g network, however, the presence of a legacy 802.11b participant will significantly reduce the speed of the overall 802.11g network. Some 802.11g routers employ a back-compatible mode for 802.11b clients called 54g LRS (Limited Rate Support). [2] The modulation scheme used in 802.11g is orthogonal frequency-division multiplexing (OFDM) copied from 802.11a with data rates of 6, 9, 12, 18, 24, 36, 48, and 54 Mbit/s, and reverts to CCK (like the 802.11b standard) for 5.5 and 11 Mbit/s and DBPSK/DQPSK+DSSS for 1 and 2 Mbit/s. Even though 802.11g operates in the same frequency band as 802.11b, it can achieve higher data rates because of its heritage to 802.11a.

• Question 138:

  A client is deploying lightweight APs. Those with LAN connections to the controller would be considered what mode of deployment, while access points deployed across a higher latency connection are deployed in what mode?

  A. HREAP; Bridge
  B. Local; Bridge
  C. HREAP; Flex Connect
  D. Local; Flex Connect
  D. Local; Flex Connect

• Question 139:

  You have a lightweight AP that has been moved to a new subnet and has become stranded because DNS and DHCP servers are unavailable. The AP cannot connect to the controller. When connected to the console port, which three minimum parameters must you configure? (Choose three.)

  A. AP IP address
  B. controller name
  C. AP hostname
  D. default gateway IP address
  E. controller IP address
  F. username and password
  A. AP IP address
  D. default gateway IP address
  E. controller IP address

  ---

  In order to manually configure static information on a LAP using the AP CLI interface, you can use these EXEC mode CLI commands: AP#capwap ap ip address

  AP#capwap ap ip default-gateway

  AP#capwap ap controller ip address

  AP#capwap ap hostname

  (optional)

  Notice the first 3 are needed for the AP to connect to the controller; the last step is optional and not needed for basic connectivity to the controller.
