Assignment 7 Part 3

1. Identify the Class B private address range.
2. Which form of NAT is the simplest form?
3. In which implementation of NAT must the network administrator define a pool of public addresses?
4. What two conditions causes overlapping to occur?
5. Protocols having packet headers that can contain network layer addresses are called:
6. Protocols used by routers to make path determination choices and share those choices with other routers are called:
7. How many routing protocols generally run on an autonomous system?
8. What are the two categories of routing protocols?
9. What are the two types of IGPs?
10. Packets bouncing endlessly around a network is a problem called:
11. Which type of routing protocol generally has faster convergence?
12. Identify some disadvantages of using link-state routing protocols.
13. A problem of RIP only using hop count as a metric is:
14. Which command will display a RIP routing table.
15. A technician enters the command "show ip route". While viewing the results she sees the route to a network was learned by the router with codes C and R. Briefly describe which route would be preferred including why it's preferred.
16. At what point is a RIP learned route considered invalid?
17. Why should the "debug ip rip" command only be used when troubleshooting?
18. Briefly describe how IGRP uses the hop count metric.
19. What are the default IGRP metrics?
20. Provide three facts about autonomous system numbers.
21. Which command allows monitoring of learned IGRP routes?
22. Give two disadvantages of using static routing.
23. Explain why static routes are very powerful.
24. Why do most network administrators use a combination of static routes and dynamic routing protocols?
25. What are quad zero routes?
