Cisco 200-355 Online Questions & Answers

• Question 401:

  Transmitter 20DB - 2db cable loss + 4 antenna gain (69db free space path loss) +4 antenna gain = 2db =?

  A. -45
  B. -46
  A. -45

• Question 402:

  A lightweight AP has been deployed in local mode in a network that consists of 10 wireless LAN controllers in a single mobility group. The AP has been configured to use primary, secondary, and tertiary Cisco WLCs. Due to a major power failure, all those Cisco WLCs are unavailable.

  Which step does the AP take next?

  A. The AP reboots and repeatedly attempts to join the configured primary, secondary, and tertiary Cisco WLCs in that order. The process continues until one of the configured Cisco WLCs is available.
  B. The AP attempts to join a Cisco WLC configured as a master controller.
  C. The AP attempts to join the Cisco WLC that has the greatest capacity available.
  D. The AP state transitions to AP Fallback Mode and continues to provide limited WLAN services (that is, no new client authentications) until a Cisco WLC is available.
  B. The AP attempts to join a Cisco WLC configured as a master controller.

  If a WLC is configured as a Master Controller, the LAP selects that WLC and sends it an LWAPP join request.

• Question 403:

  Which two statements about AES-CCMP are true? (Choose two.)

  A. It is an encryption algorithm used in the 802.11i security protocol.
  B. It is defined in 802.1X.
  C. It is the encryption algorithm used in TKIP implementations.
  D. It is required in WPA.
  E. It is required in WPA2.
  A. It is an encryption algorithm used in the 802.11i security protocol.
  E. It is required in WPA2.

  ---

  WPA2 has replaced WPA. WPA2, which requires testing and certification by the Wi-Fi Alliance, implements the mandatory elements of IEEE 802.11i. In particular, it includes mandatory support for CCMP, an AES-based encryption mode with strong security. http://en.wikipedia.org/wiki/Wi-Fi_Protected_Access

• Question 404:

  When configuring a WLC to support multiple WLANs, which type of interface must be created?

  A. dynamic
  B. ap-manager
  C. virtual
  D. management
  A. dynamic

• Question 405:

  What is a risk when initiating the containment of a rogue AP?

  A. disassociating clients of valid access points that are operated by a neighboring organization
  B. disrupting transmission of neighboring AP clients
  C. breaking the radio of the containing AP
  D. breaking the rogue client radio or its firmware
  A. disassociating clients of valid access points that are operated by a neighboring organization

• Question 406:

  Which two statements are characteristics of RF mathematics? (Choose two.)

  A. For every gain of 3 dB, multiply the transmit power mW by 2
  B. For every gain of 10 dB, multiply the transmit power mW by 100
  C. For every loss of 30 dB, multiply the transmit power mW by 1000
  D. For every loss of 30 dB, decrease the transmit power mW by 1000
  E. For every gain of 3 dB, divide the transmit power mW by 2
  A. For every gain of 3 dB, multiply the transmit power mW by 2
  E. For every gain of 3 dB, divide the transmit power mW by 2

• Question 407:

  Instructions:

  1.

  THIS TASK DOES NOT REQUIRE DEVICE CONFIGURATION

  2.

  To access the multiple-choice questions, click on the numbered boxes on the left of the top panel.

  3.

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

  Scenario:

  A Cisco Wireless LAN Controller has been correctly configured for AP and wireless client access. The WLC and AP have been connected using a configured CISCO iOS switch. Unexpected results are occurring for the AP association to the

  WLC. Refer to the exhibits to answer the question.

  

  

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

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

• Question 408:

  The Cisco WLC administrator needs the guest client traffic to be sent via a tunnel to a specified controller in the DMZ, no matter which AP the guest user is connected to. What must be configured for a WLAN to achieve this requirement?

  A. asymmetric tunneling
  B. static mobility anchor
  C. symmetric tunneling
  D. FlexConnect
  B. static mobility anchor

• Question 409:

  D. LDAP server
  E. WLC IP
  A. SSID name
  C. PSK

• Question 410:
