Read the first 7 Security Protocols & Network Optimization flashcards as text

  1. What encryption algorithm does WPA3-Personal use to replace the Pre-Shared Key (PSK) handshake?

    Answer: Simultaneous Authentication of Equals (SAE)

    WPA3-Personal replaces PSK with SAE (Dragonfly handshake), providing forward secrecy and resistance to offline dictionary attacks.

  2. Which EAP method uses server-side certificates only, with client credentials tunneled inside a TLS session?

    Answer: PEAP

    PEAP establishes a TLS tunnel using only a server certificate, then authenticates the client via MSCHAPv2 or another inner method inside the tunnel.

  3. A wireless survey shows high co-channel interference on channel 6. Which optimization technique directly addresses this?

    Answer: Reducing transmit power on overlapping APs

    Lowering transmit power reduces the RF footprint of each AP, shrinking the co-channel interference zone.

  4. Which 802.11 feature allows a client to roam between APs without re-running a full 802.1X authentication?

    Answer: 802.11r (Fast BSS Transition)

    802.11r pre-negotiates key material between APs, enabling a client to reassociate with a new AP in as few as two frames.

  5. A deauthentication flood attack is possible against WPA2 networks because management frames are unprotected. Which amendment addresses this vulnerability?

    Answer: 802.11w

    802.11w (Protected Management Frames) cryptographically protects action, disassociation, and deauthentication frames.

  6. In a WPA2-Enterprise deployment, what is the primary role of the PMK (Pairwise Master Key)?

    Answer: It seeds the 4-Way Handshake to derive the PTK used for data encryption

    The PMK is derived from 802.1X authentication and serves as the input to the 4-Way Handshake, which produces the PTK for frame encryption.

  7. A CWT candidate is asked about the CSMA/CA mechanism. What does the 'CA' stand for and why is it used in Wi-Fi instead of collision detection?

    Answer: Collision Avoidance; wireless nodes cannot detect collisions while transmitting

    Wi-Fi uses collision avoidance because a transmitting node cannot simultaneously listen for collisions on the half-duplex wireless medium.
