Q

When dealing with a Router-on-a-stick configuration, the router interface is configured to operate as a _____ link and is connected to a switch port that is configured in _____ mode. The router performs inter-VLAN routing by accepting VLAN-tagged traffic on the _____ interface coming from the adjacent switch, and then internally routing between the VLANs using subinterfaces.
