Chapter 7
1.What’s a routing table? Keeps track of the routes to use for forwarding datat to its destination
2. What is the most common static route used in a host computer? Default gateway
3. What command is used to view a PC computer 's routing table? Netstat –r /route prints
4. What is meant by a O.O.O.O network address entry with a subnet mask of 0.0. 0.0. in a PC 's routing table? Default route
5. What is the 127.0.0.1 IP address and what is it used for?loopback, the data is routed directly back to the source
14. What is the difference between a static and a dynamic routing protocol?Static routing protocol is of limited use for campuswide network routing but is essential when configuring the default route on router but dynamic routing protocols enable the router’s routingtable to be dynamically updated toaccount for loss or canges in routes or changes in data traffic.
15. What are the four key issues in dynamic routing protocols?Path determination, Metric, Convergence, Load Balancing
16. Define hop count.The number of routers the data packet must pass through to reach the destination network
17. Which of the following is not a metric used in dynamic routing protocols
a. Hop count
b. Cost
c. Runs
d. Ticks
18. A distance vector protocol typically uses what as the metric? Hop couints
22. Link state protocols issue what to update neighbor routers regarding route status? a. Hop status
b. Link state advertisements
c. "Hello" packets
d. Adjacencies
23. Which of the following are key issues of link state protocols?
a. Send updates every 90 seconds
b. Send update when routing changes
c. Use link lights to establish adjacencies
d. Use a hop count metric to determine the best route to a destination

24. RIP is classified as a
a. Distance vector protocol
b. Dynamic routing protocol
c. Link state protocol
d. a andc
e. a andb
f. b arid c
25. Define routing loops. Data is forwarded back to the
