You can find the answers to the following questions in Appendix A, "Answers to Chapter Review Questions."

1:	Router R4 has two working Ethernet interfaces, and each interface has been configured with an IP address. What is the least number of routes that R4 should have in its routing table, and why?
2:	Router R4 has a working Ethernet1 interface whose IP address is 10.10.10.10. The subnet number of the subnet attached to that interface is 10.10.10.0, with all hosts that share the first 3 octets of 10.10.10 in the same subnet. List the routing table entry that R4 will place in its routing table for this route, including the destination, outgoing interface, and next-hop router fields.
3:	Referring to Figure 12-8, list the three parts of the IP route that could be statically added to R1's configuration so that it could forward packets to the web server. Include the destination, outgoing interface, and next-hop router as appropriate. Figure 12-8. Figure Referenced in Chapter 12 Review Questions
4:	Referring to Figure 12-8, list the three parts of the IP route that R1 would learn from R2 using a routing protocol. Include the destination, outgoing interface, and next-hop router as appropriate.
5:	Referring to Figure 12-8, list the three parts of the IP route that R2 would learn from R1 in the figure. Include the destination, outgoing interface, and next-hop router as appropriate.
