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

• Question 562:

  You have a computer that runs Windows 10. You must establish a secure connection to manage a Cisco WLC. Which two methods do you use? (Choose two.)

  A. HTTPS on the WLC management IP address
  B. Telnet session on the WLC management IP address
  C. SSH session on the WLC management IP address
  D. RDP session on the WLC management IP address
  E. HTTP on the WLC management IP address
  A. HTTPS on the WLC management IP address
  C. SSH session on the WLC management IP address

• Question 563:

  Which governing body analyzes the applications and environments in which wireless networks are used?

  A. EIRP
  B. ETSI
  C. FCC
  D. IEEE
  E. WiFi Alliance
  D. IEEE

  ---

  Hence the various wireless standards prefixed with IEEE. Wireless LANs are described in IEEE 802.11 standard that contains 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac and so forth.

• Question 564:

  Which two actions would you use to begin to troubleshoot an access point that fails to join a wireless LAN controller successfully? (Choose two.)

  A. SSH to the AP.
  B. SSH to the Cisco WCS.
  C. SSH to the Cisco WLC.
  D. Issue the Cisco WLC commandebug capwap events enable
  E. Issue the Cisco WLC commanshow capwap events
  C. SSH to the Cisco WLC.
  D. Issue the Cisco WLC commandebug capwap events enable

  The controller supports the use of the Telnet and Secure Shell (SSH) protocols to troubleshoot lightweight access points. Using these protocols makes debugging easier, especially when the access point is unable to connect to the controller. You can monitor the APs dialog with the controller using the debug capwap family of commands.

• Question 565:

  You are sitting in an airport preparing to use a free WLAN. When you look at the connections in your Windows 7 wireless client, you see a network name and three boxes with a yellow shield. What does this mean?

  A. You cannot connect to this WLAN.
  B. An open ad hoc network is nearby.
  C. The WLAN in the airport is open.
  D. A secure ad hoc network is nearby.
  E. A secure WLAN is in the airport.
  F. You must provide a username and password to access the WLAN in the airport.
  B. An open ad hoc network is nearby.

  ---

  You can connect to a detected network by clicking the wireless connection icon in the status bar, clicking an SSID name (the signal strength of the associated AP is represented by green bars, five bars representing the best signal; an exclamation mark inside a yellow shield is displayed if the SSID has no security [Open authentication, no encryption]), clicking Connect and completing the security parameters when applicable. http://www.ciscopress.com/articles/article.asp?p=2131139

• Question 566:

  A customer is trying to avoid utilizing DFS frequencies in the 5-GHz spectrum, because he is concerned about interference with radar signals. Which channel should be avoided?

  A. 36
  B. 161
  C. 52
  D. 149
  C. 52

• Question 567:

  A controller is connected to a Cisco Catalyst switch. The switch port configuration looks like this:

  interface GigabitEthernet 1/0/10 switchport switchport trunk encapsulation dot1q switchport trunk allowed vlan 1,20,30,50 switchport trunk native vlan 20 switchport mode trunk

  Which controller CLI command assigns its management interface to the native VLAN interface of the Cisco Catalyst switch?

  A. config interface vlan management 20
  B. config interface vlan management 0
  C. config interface vlan management 1
  D. config interface vlan management 30
  E. config interface vlan management 50
  B. config interface vlan management 0

  ---

  Since the controller management interface is connected to the native vlan interface of the Cisco Catalyst switch, the correct command is: config interface vlan management vlan-id 0 http://www.cisco.com/en/US/docs/wireless/controller/5.0/ configuration/guide/c5mint.html#wp11828

• Question 568:

  What is the result when client exclusion is enabled with a timeout value of zero?

  A. Clients are excluded indefinitely.
  B. Clients are never excluded.
  C. Client exclusion is disabled.
  D. Clients must be explicitly included by specifying the MAC address.
  E. Exclusion and inclusion is determined by access list.
  A. Clients are excluded indefinitely.

• Question 569:

  Which statement describes the difference between LAGs on WLCs and EtherChannels switches?

  A. Cisco Unified Wireless Controller supports a maximum of one LAG, but switches support multiple EtherChannels
  B. Cisco Unified Wireless Controller supports multiple LAGs, and switches support multiple EtherChannels
  C. Cisco Unified Wireless Controller supports a maximum of two LAGs, but switches support multiple EtherChannels
  D. Cisco Unified Wireless Controller supports a maximum of one LAG, and switches support one EtherChannel per switch.
  A. Cisco Unified Wireless Controller supports a maximum of one LAG, but switches support multiple EtherChannels

• Question 570:
