What are three features of router-on-a-stick, inter-VLAN routing? (Choose three.)
both are the common inter networking devices(functionally) but the layer 3 switch has the functionality of both switch and router, layer 3 switch are most commonly used in frame relay networks, layer 3 switches are also capable of inter vlan routing
Advantages are that it is simple to implement, A Layer-3 switch (expensive) is not required, The router provides communication between VLANs.
A physical router device with an interface that routes between two or more VLANs that are attached to a VLAN network segment by a trunk link. In other words a " router on a [ TRUNK ] " which is originating from switches with independent non routing VLANs.

The IP address of each router subinterface mist be used as the default gateway for hosts on the corresponding VLAN.
Traditional inter-VLAN routing using physical interfaces does have a limitation. As the number of VLANs increases on the network, the physical approach of having one-router-interface-per-VLAN quickly becomes hindered by the physical hardware limitations of a router.Lewis, Wayne (2008-04-28).

Routing algorithms that are restricted to only work within the domain are referred as intera-domain routing algorithms and if they are not restricted only within the domains then they are inter-domain algorithms.
Using a simple show command will suffice to view that vlan's are configured properly. If the vlan's are configured properly on the routers as well as the switches, then the routers can talk to each other and so can the vlan's.show ip route - Provides a snapshot of the routing table entries.ping - verifies connectivity

inter_vlan routing on d'link DGS3612 is automatic,you just creates vlan and tag them to the port access and trunk
The protocols used to distribute routing information between AS's are known as Exterior Gateway Protocols (EGP's).
