   A hospital is deploying IoT sensors to monitor infusion pumps and patient monitors on each floor. The network team is concerned about adding latency to time-sensitive monitoring traffic and wants to ensure that even if a sensor fails, traffic continues to flow. They also need to see all device-to-device communication between IoT devices on the same floor. Which placement approach best meets these requirements?

   • ADeploy the sensor as a passive tap on the uplink from each access switch to the distribution layer.
   • BDeploy the sensor inline between each IoT device and the access switch.
   • CDeploy the sensor in the core network and monitor traffic at the data center aggregation point.
   • DDeploy the sensor on the IoT gateway that each device connects to via Bluetooth.

   Which scenario is best suited for a cloud-based IoT sensor?

   • AWhen all IoT traffic must remain on the local network segment
   • BWhen IoT devices are distributed across many locations and centralized monitoring is needed
   • CWhen IoT devices require the lowest possible network latency
   • DWhen there is no internet connectivity at the IoT site

   A smart building management system uses IoT gateways to aggregate data from thousands of sensors. The security team wants to detect and block malicious traffic from compromised sensors before it reaches the core network. They are willing to accept that the gateway may become a bottleneck. Which placement approach best meets this requirement?

   • APlace the sensor passively on the gateway's uplink.
   • BPlace the sensor on each individual IoT device.
   • CPlace the sensor inline on the IoT gateway.
   • DPlace the sensor in the core network.

   What is a key difference between cloud-based IoT sensors and on-premises sensors?

   • ACloud-based sensors can scale more easily to handle large volumes of traffic.
   • BCloud-based sensors always have lower latency than on-premises sensors.
   • COn-premises sensors cannot inspect encrypted traffic.
   • DCloud-based sensors are only used for cloud-hosted IoT devices.
