   A city is deploying a fleet of autonomous delivery robots that navigate sidewalks and roads. The robots use Wi-Fi for communication when near buildings and cellular (LTE/5G) for wide-area coverage. The robots must maintain continuous connectivity to a central control system, and handovers between Wi-Fi and cellular must be seamless to avoid losing control data. The city's IT team is evaluating IEEE 802.21 to manage these handovers. However, they are concerned about the complexity of implementing the standard. Which approach should they take to ensure seamless handovers with minimal disruption?

   • ADeploy IEEE 802.11r for fast roaming within Wi-Fi and ignore cellular handovers
   • BImplement IEEE 802.21 media-independent handover services on the robots and network infrastructure
   • CUse a proprietary handover solution from the robot manufacturer
   • DRely on the robots' built-in Wi-Fi roaming and cellular fallback mechanisms

   A network architect is planning a TSN deployment for a smart factory. The factory has a mix of legacy switches that do not support TSN and new TSN-capable switches. The architect wants to use IEEE 802.1Qcc for centralized configuration. What is the primary challenge they will face?

   • ACentralized configuration is only possible with a single vendor's equipment.
   • BThe centralized controller must be placed in a specific location to minimize latency.
   • C802.1Qcc requires a separate time synchronization network.
   • DLegacy switches may not support the TSN configuration protocols, limiting the scope of centralized management.

   A hospital is deploying a large number of IoT devices, including Wi-Fi-connected infusion pumps, Bluetooth-enabled patient monitors, and Zigbee (802.15.4) environmental sensors. All operate in the 2.4 GHz band. The hospital's network team is concerned about interference and wants to use IEEE 802.19 to manage coexistence. Select all the mechanisms that IEEE 802.19 can provide to improve coexistence in this environment.

   • ATime-division multiplexing to schedule transmissions of different technologies in separate time slots.
   • BPower control to reduce transmission power and limit interference range.
   • CDynamic frequency selection to move devices to less congested channels.
   • DEncryption of all wireless traffic to prevent eavesdropping.
