Question 1
What organization creates and manages the 802.11 standard?
c. IEEE
The Institute of Electrical and Electronics Engineers (IEEE) is an engineering
association dedicated to fostering technological innovation and excellence for the
benefit of humanity. They develop standards, in relation to Wi-Fi, for networking
communications and operations. The 802 standards committee focuses on developing
and maintaining networking standards and recommended practices for local, metro,
and other network types. Within the unlicensed spectrum bounds defined by the FCC
in North America, the IEEE creates the 802.11 standard. For Example, 802.11
channels as defined in the standard must fall within the FCC unlicensed ranges. Over
the years new technology has been introduced to improve the speed and reliability of
WLANs so the 802.11 standard has been amended to include additional features.
The correct answer is: IEEE
Question 2
The Wi-Fi Alliance certifies equipment to be compliant with IEEE standards and
compatible with other Wi-Fi equipment.
True
The Wi-Fi Alliance further defines standards within the bounds set by the 802.11
standard. The Wi-Fi Alliance promotes interoperability between the vendors of
WLAN equipment. The Wi-Fi Alliance is an important organization for wireless LAN
(WLAN) progress. In fact, the Wi-Fi Alliance owns the “Wi-Fi” trademark. The Wi-Fi
Alliance often takes the most important aspects of the 802.11 specifications and tests
those features and functions for multi-vendor functionality. Devices are provided by
product vendors to be tested, and if the products pass the interoperability tests, they
become Wi-Fi certified for a specific technology.
The correct answer is 'True'.
Question 3
IETF standards are defined through a document called an RFC Correct and each one
has a number
IETF standards are defined with several details including:
 RFC number: you can search for this number in any search engine as “RFC ###”
and quickly located and read the document. All IETF RFCs are freely available
online.
 Updated by: these are RFCs that make changes or additions to the current RFC.
 Obsoletes: this is the old version of the currently viewed RFC. When looking at
an old version of an RFC, you will see “Obsoleted by: ####” so that you know a
newer version is available.
 Contributors: the people or companies who helped to develop the standard.
 Name: the name of the standard is given in the opening title. For example, the
old version (RFC 2284) was named “PPP Extensible Authentication Protocol
(EAP)” but the new version (RFC 3748) is simply named “Extensible
Authentication Protocol (EAP).”
The correct answer is:
IETF standards are defined through a document called an [RFC] and each one
has a [number].
Question 4
Regulatory domains define the 802.11 standard PHYs for each domain.
False
Regulatory domains define which channels are available and other factors such as
output power settings, but they do not define the PHYs.
The correct answer is 'False'.
Question 5
What does a capital letter, such as the D in 802.1D, indicate about an IEEE document?
d. A capital letter indicates a standalone standard
In addition to the terms standard, draft, amendment and standard as amended, it is
important to know that the letters used can have significance. For example, 802.1X is
an important standard related to modern WLAN security. It provides the port-based
authentication we used in our enterprise WLANs. However, it is often mistakenly
called 802.1x, when it should be 802.1X. What is the difference?
 A lowercase letter indicates an amendment to a standard.
 An uppercase letter indicates a standard in and of itself.
 802.1X is not an amendment to some earlier port-based authentication standard,
but it is a standard for port-based authentication.
In the end, an x is not an X.
The correct answer is: A capital letter indicates a standalone standard
