Q13:
You get a call from a network administrator who tells you that he typed the following into his router:
Router(config)#router ospf 1
Router(config-router)#network 10.0.0.0 255.0.0.0 area 0

D The AS configuration is wrong.

Q14:
Which is true regarding EIGRP successor routes?
  1. A successor route is used by EIGRP to forward traffic to a destination.
  2. Successor routes are saved in the topology table to be used if the primary route fails.
  3. Successor routes are flagged as "active" in the routing table.
  4. A successor route may be backed up by a feasible successor route.
