1 Chabot College Chapter 5 – Routing Protocols: IGRP Review Questions Semester IIIELEC 99.09 Semester III ELEC 99.09

2 6. After a router determines which path to use for a packet, it can then proceed with which of the following? A. A broadcast B. Storing the packet in a routing table C. Choosing a routing protocol D. Switching the packet A. A broadcast B. Storing the packet in a routing table C. Choosing a routing protocol D. Switching the packet

3 7. The success of dynamic routing depends on which of the following? A. Manually entering routes B. Maintaining a routing table C. Periodic routing updates D. B and C A. Manually entering routes B. Maintaining a routing table C. Periodic routing updates D. B and C

4 8. ________ routing protocols determine the direction and distance to any link in the internetwork; ________ routing protocols are also called the shortest path first A. Distance-vector; link-status B. Distance-vector; hybrid C. Link-state; distance-vector D. Dynamic; static A. Distance-vector; link-status B. Distance-vector; hybrid C. Link-state; distance-vector D. Dynamic; static

5 9. Which of the following is not a variable IGRP uses to determine a composite metric? A. Bandwidth B. Delay C. Load D. IGRP uses all of these A. Bandwidth B. Delay C. Load D. IGRP uses all of these

6 10. To select IGRP as a routing protocol, which command do you use? 10. To select IGRP as a routing protocol, which command do you use? A. show igrp B. router network igrp C. enable igrp D. router igrp A. show igrp B. router network igrp C. enable igrp D. router igrp

7 11. IGRP is a _________ based protocol A. Time B. Cost C. Distance-vector D. Link-state A. Time B. Cost C. Distance-vector D. Link-state

8 12. What is one advantage of dynamic routing? 12. What is one advantage of dynamic routing? A. Takes little network overhead and reduces network traffic B. Reduces unauthorized break-ins because security is tight C. Adjusts automatically to topology or traffic changes D. Requires little bandwidth to operate efficiently A. Takes little network overhead and reduces network traffic B. Reduces unauthorized break-ins because security is tight C. Adjusts automatically to topology or traffic changes D. Requires little bandwidth to operate efficiently

9 13. IGRP does not use which of the following as part of the metric? A. Bandwidth B. Delay C. Load D. Hop count A. Bandwidth B. Delay C. Load D. Hop count

10 14. Which one of the following configuration commands should be configured to broadcast the network 10.1.1.0/24 using IGRP? A. RouterA# network 10.1.1.0 B. RouterA(config-router)# network 10.1.1.0 C. RouterA(config)# network 10.0.0.0 D. RouterA(config-router)# network 10.0.0.0 A. RouterA# network 10.1.1.0 B. RouterA(config-router)# network 10.1.1.0 C. RouterA(config)# network 10.0.0.0 D. RouterA(config-router)# network 10.0.0.0

11 15. To enable IGRP routing protocol, you must type “router igrp” A. True B. False A. True B. False

12 16. What is a valid metric for IGRP? A. Reliability B. Hop count C. MTU D. Both A and C A. Reliability B. Hop count C. MTU D. Both A and C

13 17. For routers to communicate IGRP without redistribution, they must be in the same ____________ A. Autonomous system B. Interior gateway C. Exterior gateway D. Domain A. Autonomous system B. Interior gateway C. Exterior gateway D. Domain

14 18. Which of the following are true of administrative distance? A. Measures the distance to a destination network B. Only applies to IGRP and EIGRP C. Measures the “reliability” of an IP routing protocol D. The higher the value, the more important the routing information A. Measures the distance to a destination network B. Only applies to IGRP and EIGRP C. Measures the “reliability” of an IP routing protocol D. The higher the value, the more important the routing information

15 19. What is the default route on an IP network? A. This is the route that will be chosen first by IP for delivery of a datagram B. The address of the nearest downstream neighbor in a Token Ring network C. At the router, it is a route manually defined as the path to take when no route to the destination is known D. Any dynamic route listing in a routing table A. This is the route that will be chosen first by IP for delivery of a datagram B. The address of the nearest downstream neighbor in a Token Ring network C. At the router, it is a route manually defined as the path to take when no route to the destination is known D.
