A The corporate head office router will have a more specific static route and the branch office router will have a default route.
B The corporate head office router and the branch router will both have default routes.
C The corporate head office router will have a default route and the branch site will have a more specific static route.
D The corporate head office router and the branch office router will both have specific static routes.
Correct Answer: The corporate head office router will have a more specific static route and the branch office router will have a default route.
