   A hospital has IoT devices (smart beds) that are classified by Device-ID. The beds need to communicate with a nurse call system on a different subnet. A security policy allows this traffic, but it is still being blocked. The admin has verified the policy is correct and the Device-ID tag is correct. What is the most likely remaining cause?

   • AThe SD-WAN appliance is not the gateway for the nurse call system.
   • BThe nurse call system's subnet is not included in Device-ID network settings.
   • CThe nurse call system is not sending traffic back to the beds.
   • DThe smart beds are sending traffic from a different source IP than expected.

   A university is deploying IoT sensors across multiple buildings. Each building has its own VLAN and subnet. The security team wants Device-ID to classify all sensors, but they are on different subnets. What is the most efficient way to configure Device-ID for this environment?

   • AUse DHCP reservations to assign IPs from a single subnet for all sensors.
   • BEnable Device-ID on the uplink interface to capture all traffic regardless of subnet.
   • CAdd each sensor subnet to the Device-ID network settings individually.
   • DConfigure a single supernet that covers all sensor subnets.

   A security admin is configuring Device-ID for a new IoT deployment. The devices are on a subnet that is configured in Device-ID. However, the admin notices that some devices are not being classified because they are using a protocol that Device-ID does not recognize. What is the best way to handle this?

   • AMove the devices to a different subnet that uses a supported protocol.
   • BCheck if the protocol can be identified by Device-ID or if a custom signature is needed.
   • CDisable Device-ID for the subnet and rely on IP-based policies.
   • DEnable Device-ID on the WAN interface to capture more traffic.
