You can take the CCNP tests in any order, but you should have passed the CCNA exam before pursuing your CCNP. | 416 Appendix A Practice Exam 12. C. EIGRP routes have a default administrative distance of 90. 13. B D. The show ip bgp neighbor command displays all the advertised routes and the show ip bgp command looks at all the connections. 14. D. If you write out the networks 172.16.100.0 24 and 172.16.106.0 24 in binary and see how many leading bits that they have in common you will find that the first 20 bits are the same for both networks. If you then convert these 20 bits back into decimal you will have the address of the summarized route. 15. A and B. In an OSPF network there must always be a backbone area which is numbered as Area 0. If a router has any of its interfaces connected to Area 0 that router is said to be a backbone router. 16. A B C E F. Access lists snapshot routing compression techniques Dial-on-Demand Routing DDR and incremental updates all can help reduce bandwidth usage. 17. A.

The answer here can be tricky. There are six initialization steps but not all of them are always seen. Many times the Loading phase is not necessary between the Exchange state and the Full state. 24. B. Route summarization is most effective when used with contiguous address space because contiguous address space tends to have the most higher-order bits in common. 25. C. The init state is simply the state of receiving Hello packets on the interface no
