  3.

  There is one multiple-choice question with this task. Be sure to answer the question before selecting the Next button

  Scenario:

  You are deploying a small wireless test network in a lab. The network is made up of a wireless controller (WLC1), a dual radio access point (AP1) and a switch (SW1) that is configured as a DHCP server. The IP subnet being used for this

  network is 10.10.0/24. You would like to test how clients join the network and from which DHCP server they receiver an address.

  

  

  

  

  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. The 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. The 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 533:

  What is the function of the Cisco AnyConnect DART tool?

  A. creates a compressed bundle of client logs and information
  B. visualizes a WLAN environment, showing the possible locations of problems
  C. gathers statistics from neighboring clients for comparison to the baseline
  D. helps to troubleshoot a WLAN connection by using easy-to-use wizards and statistic viewers
  A. creates a compressed bundle of client logs and information

  ---

  AnyConnect offers the DART module that can be used to analyze and troubleshoot connections.

  The information collected by DART can be examined locally or exported and sent to a network support desk for analysis. The DART tool is able to create a bundle to log information for all the wireless clients.

• Question 534:

  Refer to the exhibit.

  

  Which menu gives you access to manage background tasks in Cisco WCS?

  A. None, because the General tab provides access to the management of background tasks
  B. Monitor
  C. Configure
  D. Services
  E. Administration
  F. Tools
  E. Administration

  ---

  The Administration menu enables you to schedule tasks like making a backup, checking a device status, auditing your network, synchronizing the MSE, and so on. It also contains Logging to enable various logging modules and specify restart requirements. For user administration such as changing passwords, establishing groups, setting application security settings, and so on, choose AAA. From the Administration Menu, you can also access the licensing information, set user preferences, and establish high availability (a secondary backup device running WCS).

• Question 535:

  Which statement about customization of a web page that is used on a WLC to authorize guest users is true?

  A. The administrator can use either a modified internal login page or the customized web page.
  B. The administrator can use only the internal login page, and only the organization logo can be changed.
  C. The administrator can use only the internal login page with a customized logo, headline, and message.
  D. The administrator can use only the customized web page that is uploaded to a WLC.
  A. The administrator can use either a modified internal login page or the customized web page.

• Question 536:

  Which technique divides a 20-MHz channel into 52 subchannels to transmit wireless data?

  A. OFDM
  B. DSSS
  C. CCK
  D. FHSS
  A. OFDM

• Question 537:

  What are two attributes used to characterize antenna performance? (Choose two.)

  A. attenuation
  B. beamwidth
  C. gain
  D. harmony
  E. interference
  B. beamwidth
  C. gain

• Question 538:

  A wireless engineer has been asked to plan a deployment covering the aisles of a warehouse with optimal coverage while bleeding RF across aisles. Which antenna type provides the necessary coverage?

  A. patch
  B. omnidirectional
  C. Yagi
  D. parabolic dish
  A. patch

• Question 539:

  A WLAN deployment uses a combination of Cisco Aironet 1260 APs and multiple Cisco 5500 Wireless LAN Controllers to provide wireless LAN access to end- users. The network administrator has decided to use DHCP Option 43 to enable the APs to discover the wireless LAN controllers. When configuring the DHCP scope, which format should be used for the Cisco WLC addresses?

  A. a comma-separated ASCII string of Cisco WLC AP-manager addresses
  B. a comma-separated ASCII string of Cisco WLC management addresses
  C. a comma-separated ASCII string of Cisco WLC virtual IP addresses
  D. a hexadecimal string of Cisco WLC AP-manager addresses
  E. a hexadecimal string of Cisco WLC management addresses
  F. a hexadecimal string of Cisco WLC virtual IP addresses
  E. a hexadecimal string of Cisco WLC management addresses

  ---

  Complete these steps in order to configure DHCP Option 43, in the embedded Cisco IOS DHCP server, for all Cisco Aironet APs that run Cisco IOS. This includes all APs except for the VxWorks 1000 Series (see the next section) and the 600

  Series OEAP which does not use Option 43. ip dhcp pool

  network

  default-router

  dns-server

  option 43 hex

  The hexadecimal string in step 3 is assembled as a sequence of the TLV values for the Option 43 suboption: Type + Length + Value. Type is always the suboption code 0xf1. Length is the number of controller management IP addresses times

  4 in hex. Value is the IP address of the controller listed sequentially in hex.

• Question 540:

  When the pre-shared key authentication method is used for WPA or WPA2, for which two functions is the pre-shared key used? (Choose two.)

  A. to act as the Group Transient Key during the bidirectional handshake
  B. to act as the Pairwise Master Key during the bidirectional handshake
  C. to derive the nonce at each side of the exchange
  D. to derive the Pairwise Transient Key
  B. to act as the Pairwise Master Key during the bidirectional handshake
  D. to derive the Pairwise Transient Key

  ---

  Pre-shared key (PSK) is computed based on a shared secret (pass- phrase) which was previously shared between the two parties using some secure channel before it needs to be used. It is used to identify both peers to each other.

  The strength of the PSK depends on the strength of the pass-phrase. The strength of the PSK is important, because WPA-Personal (and WPA2-Personal) use the PSK as the Pairwise Master Key (PMK). The PMK, when combined with two random numbers (nonces) and the MAC addresses of the access point and the client, produces a unique Pairwise Transient Key (PTK) that secures the unicast traffic between the access point and the client. A new PTK is produced each time a client connects to the access point.
