   A network engineer is configuring 802.1X on a Juniper switch for a mixed environment with both 802.1X-capable and non-802.1X devices.

   • AConfigure a firewall filter to restrict traffic to the printer and scanner on the port.
   • BConfigure the port as an access port in the restricted VLAN and disable 802.1X.
   • CUse dynamic VLAN assignment from RADIUS to place all devices in the restricted VLAN.
   • DConfigure a guest VLAN for the restricted network and enable MAB as a fallback.
