CWNP FINAL STUDY GUIDE QUESTIONS & ANSWERS. VERIFIED. 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. - -What organization creates and manages the 802.11 standard? 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 Wi-Fi Alliance certifies equipment to be compliant with IEEE standards and compatible with other Wi-Fi equipment. 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)." - -IETF standards are defined through a document called an RFC and each one has a number. 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'. - -Regulatory domains define the 802.11 standard PHYs for each domain. 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. - -What does a capital letter, such as the D in 802.1D, indicate about an IEEE document
