   How are Device-IDs used in security policy enforcement?

   • AAs match criteria in security policies to apply rules to specific IoT devices
   • BTo replace the need for user authentication on the network

   A university is deploying new smart projectors on its network. The security team wants to create a security policy that allows the projectors to communicate only with the media server. They have not yet configured a Device-ID for the projectors. What is the first step they must take to enforce this policy effectively?

   • ACreate a Device-ID for the projectors so that the security policy can reference the device type.
   • BEnable logging on the default security policy to monitor the projectors' traffic.
   • CConfigure the projectors to use a static IP address so they can be identified in the policy.
   • DCreate a security policy that allows all traffic from the projector subnet to the media server.

   Why is logging IoT events important for security auditing?

   • AIt provides a historical record of device activity that can be reviewed for compliance and security incidents
   • BIt replaces the need for real-time monitoring
   • CIt reduces the amount of network traffic generated by IoT devices
   • DIt automatically prevents all security breaches
