Static routing will be used for a network connecting a corporate head office and a branch office. The head office has many attached subnetworks, while the branch office has one subnetwork and one connection to the head office. Which configuration is most likely on the head-office and branch-office routers?

Explanation

A branch router with one connection to the rest of the network is a stub router, so a default route can forward all traffic for nonlocal destinations toward the head office. The head-office router needs a specific static route to the branch subnet for return traffic. Cisco Networking Academy documentation likewise configures a default route on stub routers and specific routes on the upstream router for their internal networks.
