   What is a primary use case for placing an IoT sensor at the network edge, such as on a switch or access point?

   • ATo provide a centralized view of cloud workloads
   • BTo monitor all traffic across the entire enterprise network from a single point
   • CTo reduce the need for any other security controls in the network
   • DTo inspect traffic from IoT devices as soon as it enters the network

   A government agency is deploying IoT sensors for building automation. They have a requirement to inspect all traffic, including traffic that stays within a building, but they also have a limited budget for sensor hardware. They are considering a combination of edge and core placement. Which combination is most cost-effective while meeting the requirement?

   • APlace sensors inline on every link between buildings.
   • BPlace sensors only in the core network.
   • CPlace sensors on the access switches in each building and also in the core.
   • DPlace sensors on every IoT device.

   What is a key characteristic of an inline IoT sensor placement?

   • AIt inspects traffic as it passes through, allowing immediate blocking of threats.
   • BIt only monitors traffic from cloud-based IoT devices.
   • CIt receives a copy of traffic from a switch port, so it cannot block traffic.
   • DIt has no impact on network performance because it is out of band.

   What is a primary advantage of placing an IoT sensor in the core network?

   • AIt is the only way to inspect encrypted IoT traffic.
   • BIt can monitor traffic from many different segments in a centralized location.
   • CIt eliminates the need for any other security controls.
   • DIt provides the lowest possible latency for IoT device communication.

   Which statement accurately describes a passive IoT sensor placement?

   • AIt inspects a copy of the traffic, so it does not add latency to the original data flow.
   • BIt requires a dedicated physical appliance at every switch.
   • CIt is always deployed in the cloud.
   • DIt sits in the data path and can drop malicious packets.
