The 802.11i standard has two main components to it. Which of the following best describes these two components?

A.
One component uses AES to allow for backward compatibility. The other component uses the TKIP algorithm in counter mode and CBC-MAC.

B.
One component uses 802.1x to allow for backward compatibility. The other component uses the 3DES algorithm in counter mode and CBC-MAC.

C.
One component uses TKIP to allow for backward compatibility. The other component uses the AES algorithm in counter mode and CBC-MAC.

D.
One component uses CCMP to allow for backward compatibility. The other component uses the AES algorithm in counter mode and CBC-MAC.

Explanation:
Companies and individuals that already have a WLAN setup, can apply
802.11i, which uses TKIP. TKIP provides more keying material for the RC4 algorithm
that is used within WEP. Companies that have not yet deployed a WLAN, can use the
portion of the standard that uses the AES algorithm in counter mode and uses
CBC-MAC.
