Chapter 1 Review SEC330 Questions
and Answers 100% correct
The IEEE 802.11-2012 standard mandates this encryption for robust security network
associations and the optional use of which other encryption? - answer E.
The 802.11-2012 standard de nes what is known as a robust security network (RSN)
and robust security network associations (RSNAs). CCMP/AES encryption is the
mandated encryption method, whereas TKIP/ARC4 is an optional encryption method.
What wireless security solutions are defined by Wi-Fi Protected Access? (Choose all
that apply.) - answer A, C.
The Wi-Fi Protected Access (WPA) certi cation was a snapshot of the not-yet-released
802.11i amendment, supporting only the TKIP/ARC4 dynamic encryption-key
generation. 802.1X/EAP authentication was required in the enterprise, and passphrase
authentica-
tion was required in a SOHO or home environment. LEAP is Cisco-proprietary and is
not speci cally de ned by WPA. Neither dynamic WEP nor CCMP/AES were de ned for
encryption. CCMP/AES dynamic encryption is mandatory under the WPA2 certi cation
Which wireless security standards and certifications call for the use of CCMP/AES
encryp-
tion? (Choose all that apply.) - answer B, D.
The 802.11-2012 standard de nes CCMP/AES encryption as the default encryp- tion
method, whereas TKIP/ARC4 is the optional encryption method. This was originally de
ned by the 802.11i amendment, which is now part of the 802.11-2012 standard. The Wi-
Fi Alliance created the WPA2 security certi cation, which mirrors the robust security de
ned by the IEEE. WPA2 supports both CCMP/AES and TKIP/ARC4 dynamic encryp-
tion key management.
A robust security network (RSN) requires the use of which security mechanisms?
(Choose all that apply.) - answer D, F.
The required encryption method de ned by an RSN wireless network is Counter Mode
with Cipher Block Chaining Message Authentication Code Protocol (CCMP), which uses
the Advanced Encryption Standard (AES) algorithm. An optional choice of encryption is
the Temporal Key Integrity Protocol (TKIP). The 802.11-2012 standard also requires the
use of an 802.1X/EAP authentication solution or the use of preshared keys for robust
security. It should be noted that TKIP encryption cannot be used for 802.11n and
802.11ac data rates.
The Wi-Fi Alliance is responsible for which of the following certification programs?
(Choose all that apply.) - answer A, D.
802.11-2012 is the IEEE standard, and WEP (Wired Equivalent Privacy) is de ned as
part of the IEEE 802.11-2012 standard. PSK is not a standard; it is an authentication
