  1. Chabot College • Chapter 5 – Routing Protocols: IGRP Review Questions Semester IIIELEC 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? • 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? • 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
