CWNP Study Guide Test 1 Questions & Answers 100% CORRECT 2024/2025 4-way Handshake - ANSWERSA protocol that uses a frame exchange between two stations (STAs) to create dynamic encryption keys that are unique to any two radios. Either preshared key (PSK) or 802.1X authentication creates a Pairwise Master Key (PMK) that seeds the 4-Way Handshake process. The four frame exchange completes the authentication process once the final encryption keys are created. 40 mhz intolerant - ANSWERSa bit potentially set in the 802.11 frame allowing STAs to indicate that 40 MHz channels should not be used in their BSS or in surrounding networks. The bit is processed only in the 2.4 GHz band. 802.11 - ANSWERSA standard maintained by the IEEE for implementing and communicating with wireless local area networks (WLANs). Regularly amended, the standard continues to evolve to meet new demands. Several Physical Layer (PHY) methods are specified and the Medium Access Control (MAC) sublayer is also specified. 802.11 state machine - ANSWERSThe 802.11 state machine defines the condition of the connection of a client STA to another STA and can be in one of the three states Unauthenticated/Unassociated, Authenticated/Unassociated, or Authenticated/Associated. 802.11a - ANSWERSAn 802.11 standard that operates in the 5 GHz frequency band and, by using OFDM, supports speeds up to 54 Mbps. 802.11aa - ANSWERSan 802.11 amendment that added support for robust audio and video streaming through MAC enhancements. it specifies a new category of station called a Stream Classification Service (SCS) station. The SCS implementation is optional for a WMM QoS station. 802.11ac - ANSWERSAn 802.11 amendment that operates in the 5GHz band. It uses MU-MIMO, beamforming, and 256 QAM technology, up to 8 spatial streams and OFDM modulation. Support is included for data rates up to 6933.3 Mbps
