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

  1. What is the primary security risk associated with using open (unauthenticated) Wi-Fi networks?

    Answer: Eavesdropping due to unencrypted over-the-air transmissions

    Open networks transmit data without encryption, allowing any nearby device in promiscuous mode to capture and read the traffic.

  2. Which 802.11ax (Wi-Fi 6) feature reduces power consumption for IoT devices by scheduling when they wake to receive data?

    Answer: TWT (Target Wake Time)

    TWT allows an AP and client to negotiate specific times for the client to wake and exchange data, significantly extending battery life.

  3. BSS Coloring in 802.11ax is designed to improve which aspect of WLAN performance?

    Answer: Spatial reuse by allowing concurrent transmissions in overlapping BSSs

    BSS Coloring tags frames with a color identifier so stations can differentiate overlapping BSS transmissions and defer only when necessary, improving spatial reuse.

  4. A wireless technician discovers that a client is sending 802.11 probe requests with randomized MAC addresses. What is the security purpose of this client behavior?

    Answer: To prevent tracking of the device's physical location across Wi-Fi networks

    MAC address randomization during scanning prevents third parties from correlating probe requests to a specific device over time.

  5. In a high-density WLAN deployment such as a stadium, which channel width is recommended for 5 GHz to maximize the number of available non-overlapping channels?

    Answer: 20 MHz

    20 MHz channels maximize the number of non-overlapping channels available in the 5 GHz band, reducing co-channel interference in dense environments.

  6. Which protocol does WPA3-Enterprise mandate for protecting management frames to comply with its enhanced security requirements?

    Answer: 802.11w (Protected Management Frames)

    WPA3-Enterprise mandates 802.11w PMF to protect deauthentication and disassociation frames from spoofing attacks.

  7. A WLAN controller shows a 'hidden node' problem between two clients. Which 802.11 mechanism is designed to mitigate this issue?

    Answer: RTS/CTS (Request to Send / Clear to Send)

    RTS/CTS reserves the wireless medium before transmitting, alerting hidden nodes that cannot hear each other to defer their transmissions.
