As mentioned in the introduction, "All About the CCNP, CCDP, and CCIP Certifications," you have two choices for review questions. The questions that follow next give you a bigger challenge than the exam itself by using an open -ended question format. By reviewing now with this more difficult question format, you can exercise your memory better and prove your conceptual and factual knowledge of this chapter. The answers to these questions are found in Appendix A.
For more practice with examlike question formats, including questions using a router simulator and multichoice questions, use the exam engine on the CD-ROM.
Which systems would you configure as Level 1-2 systems?
Which IS-IS configuration uses a full mesh and simulates a broadcast technology?
What are the four stages of the routing process?
What does an LSP contain?
When are LSPs generated?
State at least one of the main steps of the flooding process on a point-to-point link.
Which three fields determine whether the LSP is valid?
Once the link-state databases are synchronized, the Dijkstra algorithm is run. Describe where the router places itself in the tree.
State two criteria in determining which paths are to be placed in the forwarding database.
What are the ISO metrics?
How many equal-cost paths is it possible to have in the IS-IS routing table of a Cisco router?
What is a narrow metric?
Where is the IS-IS metric applied?
What action will the routing process take if it sees an incomplete LSP fragment?
Why is the IS-IS default of cost the only metric supported by Cisco?
When designing a network for fast convergence, what is the compromise that you need to consider?
What is a suboptimal routing decision?
Where does route summarization take place?
When is a DIS elected in a WAN environment?
Explain briefly how the IS-IS NBMA cloud is different than the configuration of the OSPF cloud.
