Routers R1 R2, and R3 are running a classful routing protocol between them. Assuming that router R1 advertises all directly connected networks, how will these networks be represented in router R3's routing table?

  • A. Router R3's routing table can only contain one of the routes, which will result in route flapping.
  • B. Router R3's routing table will have one entry for 10.1.1.0/24 and one entry for 10.1.2.0/24.
  • C. The networks will be represented with one entry of 10.0.0.0/8 in router R3's routing table.
  • D. The networks will be represented with one entry of 10.0.0.0/24 in router R3's route table.


Answer : C

  • C. The protocol field of the network layer header.
  • D. The port field of the network layer address.


Answer : B

Static routing will be used in a network between a corporate head office, with many connected networks, and a branch office, with one connection to the head office. Which of the following best describes the likely configuration?

  • B. The corporate head office router and the branch office router will both have specific static routes.
  • C. The corporate head office router and the branch router will both have default routes.
  • D. The corporate head office router will have a more specific static route and the branch office router will have a default route.
