  1. A hotel needs to isolate guest Wi-Fi traffic from the property management system on the same physical infrastructure. What is the best solution?

    Answer: Use VLANs mapped to separate SSIDs for guest and management traffic

    VLAN segmentation allows multiple logical networks to share the same physical AP and switches while keeping traffic isolated at Layer 2.

  2. A user in a large open-plan office reports excellent signal strength but very slow speeds. The SNR is 25 dB. What is the most likely cause?

    Answer: High client density causing medium contention and airtime exhaustion

    In high-density environments, even with strong signal, too many clients competing for airtime on the same channel degrades throughput significantly.

  3. You are designing a wireless network for an outdoor stadium seating 50,000 people. Which deployment strategy best addresses high user density?

    Answer: Deploy directional sector antennas aimed at seating sections with small, controlled cells

    Directional antennas focused on seating sections create many small, low-interference cells, distributing client load across more APs and channels.

  4. A manufacturing plant running 802.11n reports that adding a new CNC machine causes packet loss on the wireless network. A spectrum scan shows wideband noise. What should you investigate first?

    Answer: Whether the CNC machine's motor or VFD emits RF interference

    Variable frequency drives (VFDs) and electric motors in industrial equipment can emit significant broadband RF noise that disrupts wireless communications.

  5. After migrating from WPA2-Personal to WPA2-Enterprise, several legacy printers can no longer connect. What is the most likely reason?

    Answer: Legacy printers lack 802.1X supplicant software to authenticate to the RADIUS server

    WPA2-Enterprise requires an 802.1X supplicant for EAP-based authentication, which many older IoT devices and printers do not support.

  6. A network admin notices that an unknown AP with a familiar SSID appears in rogue AP reports. Users may be unknowingly connecting to it. What type of attack is this?

    Answer: Evil twin or honeypot AP attack

    An evil twin AP mimics a legitimate SSID to lure clients into connecting, enabling credential theft and man-in-the-middle attacks.

  7. A healthcare clinic deploys 802.11ac but finds VoIP calls on wireless drop when nurses move between rooms. What feature should be enabled to fix this?

    Answer: 802.11k and 802.11v for assisted roaming

    802.11k provides neighbor reports and 802.11v enables BSS transition management, together helping clients roam proactively before signal degrades.
