   A company is deploying new IoT devices and wants to ensure they are classified by Device-ID. The devices are on a new subnet that has been added to Device-ID. What is the next step to verify that Device-ID is working correctly?

   • ACreate a security policy that allows all traffic from the new subnet.
   • BAdd the devices to a static ARP table on the SD-WAN appliance.
   • CCheck the Device-ID logs to confirm the devices are being classified.
   • DReboot the SD-WAN appliance to apply the new configuration.

   A company is deploying IoT devices across multiple sites. Each site has its own SD-WAN appliance. The devices at each site are on different subnets. The security team wants Device-ID to classify all devices consistently across sites. What is the most important configuration consideration?

   • AEnsure each site's Device-ID network settings include the local IoT subnet.
   • BUse the same subnet at every site for IoT devices.
   • CConfigure a central Device-ID policy that applies to all sites.
   • DEnable Device-ID on the WAN interface at each site.

   A hospital is deploying IP-based infusion pumps on a dedicated IoT subnet (10.20.30.0/24). The pumps must be identified by Device-ID so that security policies can be applied based on the device type. The network team has already created the VLAN and assigned the subnet. What additional network setting must be configured in the SD-WAN fabric to ensure Device-ID can classify these pumps?

   • AAssign a loopback interface on the SD-WAN appliance with an IP in the 10.20.30.0/24 range.
   • BConfigure a static ARP entry for each pump's IP address in the SD-WAN appliance.
   • CEnable DHCP snooping on the VLAN to dynamically map MAC addresses to IP addresses for Device-ID.
   • DAdd the 10.20.30.0/24 subnet to the Device-ID network settings so the fabric knows which IP range to inspect for IoT devices.
