   A school has a single SSID for students and teachers. Teachers should be able to discover a printer in the staff room, but students should not. The WLC is configured with a policy profile for the SSID. What is the best way to achieve this?

   • APut the printer on a separate VLAN and only allow teachers on that VLAN.
   • BCreate two mDNS profiles: one with the printer for teachers, one without for students, and assign them via RADIUS-based policy profiles.
   • CUse the same mDNS profile for both and rely on the printer's access control list.
   • DDisable mDNS for the entire SSID and use a static DNS entry for the printer.

   A hospital has a guest SSID on VLAN 10 and a staff SSID on VLAN 20. Doctors need to print to AirPrint printers that are on the staff VLAN while connected to the guest SSID. The WLC is already configured with an mDNS profile that includes the printers. What must be configured so that guest users can discover and use the printers?

   • AEnable mDNS snooping globally on the WLC and add the guest SSID to the mDNS profile.
   • BCreate a new mDNS profile for the guest SSID and bind it to the guest policy profile.
   • CConfigure the guest SSID to use the same VLAN as the staff SSID so mDNS broadcasts reach the printers.
   • DBind the existing mDNS profile to the guest policy profile and ensure the guest VLAN is in the mDNS gateway's bridge domain.
