Your instructor is right. We have a pretty big Vlanned network (3000 nodes). The only way for the traffic originating from one subnet to get to another subnet is to go through a router. Therefore, each Vlan (or subnet) needs an individual gateway (router) to get to other subnets. That is why you need a standby HSRP group for each subnet.
Side note - Cisco recommends that Vlan correspond to subnets - it is easier to keep track of things. Hope this helps Elwood P.
