Cisco 200-355 Online Questions & Answers

• Question 471:

  Which type of authentication is used initially by a controller-based AP so that a guest client can get an IP address?

  A. 802.1x
  B. EAP
  C. LEAP
  D. open authentication
  E. TLS
  F. SSL
  D. open authentication

  ---

  Open authentication allows any device to authenticate and then attempt to communicate with the access point. Using open authentication, any wireless device can authenticate with the access point, but the device can communicate only if its Wired Equivalent Privacy (WEP) keys match the access point's WEP keys. Devices that are not using WEP do not attempt to authenticate with an access point that is using WEP. Open authentication does not rely on a RADIUS server on your network. http://www.cisco.com/c/en/us/td/docs/routers/access/wireless/software/guide/SecurityAuthenticationTypes.html#wp1035025

• Question 473:

  Which purpose does a spectrum analyzer serve during a site survey?

  A. Detect and measure RF energy on a frequency.
  B. Identify and monitor rogue APs in the environment
  C. Capture and save RF traffic to analyze it offline.
  D. Generate a list of interference reports.
  A. Detect and measure RF energy on a frequency.

• Question 474:

  Which method of encryption does the 802.11i standard use?

  A. AES/CCMP
  B. AES/ECB
  C. AES/OCB
  D. TKIP
  E. both AES/ECB and AES/CCMP
  A. AES/CCMP

  Counter Mode Cipher Block Chaining Message Authentication Code Protocol, Counter Mode CBC-MAC Protocol or simply CCMP (CCM mode Protocol) is an encryption protocol designed for Wireless LAN products that implement the

  standards of the IEEE 802.11i amendment to the original IEEE 802.11 standard. CCMP is an enhanced data cryptographic encapsulation mechanism designed for data confidentiality and based upon the Counter Mode with CBC -MAC (CCM)

  of the AES standard. It was created to address the vulnerabilities presented by WEP, a dated, insecure protocol.
