Which route will a router use to forward an IPv4 packet after examining its routing table for the best match with the destination address?
- a level 1 child route
- a level 1 parent route
- a level 2 supernet route
- a level 1 ultimate route
Explanation: If the best match is a level 1 ultimate route then the router will forward the packet to that network. Level 1 parent route is a route that contains subnets and is not used to forward packets. Level 1 child routes and level 2 supernet routes are not valid routing table entries.
