Question 2 Multiple Choice (Single Answer)

What distinguishes traditional routing from router-on-a-stick?

  1. Traditional routing is only able to use a single switch interface. Router-on-a-stick can use multiple switch interfaces.
  2. Traditional routing requires a routing protocol. Router-on-a-stick only needs to route directly connected networks.
  3. Traditional routing uses one port per logical network. Router-on-a-stick uses subinterfaces to connect multiple logical networks to a single router port.
  4. Traditional routing uses multiple paths to the router and therefore requires STP. Router-on-a-stick does not provide multiple connections and therefore eliminates the need for STP.
