The answers to the following questions can be found in Appendix A. Some of the questions in this section are repeated from the "Do I Know ThisAlready" Quiz so that you can gauge the advancement of your knowledge of this subject matter.
1. Briefly explain why Cisco IOS troubleshooting commands and tools need proper handling.
2 What does proper handling of troubleshooting tools entail?
3 Define switching and specify whether it is considered a complex task.
4 Define routing and compare its complexity to switching.
5 List the sources of information used by a routing process for building its routing table.
6 When a packet is process-switched, what major tasks are performed?
7 Provide a short and generic explanation for route caching (or fast switching) and the purpose behind it.
8 Which of the route caching methods are not enabled by default? And from which configuration mode (prompt level) can they be enabled?
9 On which component of the Cisco 7000 router is the Fast Switch Cache located?
10 Name the two major components that participate in the routing and switching tasks within a Cisco 7000 router.
11 What is the difference between the Silicon Switch Processor (SSP) and the Switch Processor (SP) with respect to the switching cache options?
12 What is the command for enabling IP fast switching on an interface?
13 What is the command for enabling IP autonomous switching on a Cisco 7000 series router interface?
14 What is the command for enabling IP silicon switching on a Cisco 7000 series router (with SSP) interface?
15 With regard to speed and switching optimization, how did Cisco Systems improve the Cisco 7500 routers in comparison to the 7000 series?
16 What switching method (route caching) can be enabled on the 7000/7500 series routers' VIP cards?
17 On which Cisco router models is Netflow switching supported? (Specify the IOS version.)
18 What information does Netflow use as the basis of identifying a flow?
19 Briefly describe the advantages of Netflow switching. Also specify whether there should be any precautions with respect to enabling Netflow switching.
