web dev net platform | 11. Which of the following commands would you use to configure a default route to any destination NOT found in the routing table of router PC1 ?

1. PC1 (config)# ip default-route 0.0.0.0 255.255.255.255 s0
2. PC1 (config)# ip route 0.0.0.0 0.0.0.0 s0
3. PC1 (config)# ip default-route 0.0.0.0 0.0.0.0 s0
4. PC1 (config)# ip route 0.0.0.0 255.255.255.255 s0

12. Router PC1 has just received a packet and needs to route it. What action must this router take in order to route incoming packets?

1. None of the above
2. Validate sources of routing information.
3. Inspect the routing table to select the best path to the destination network addresses.
4. Inspect the ARP table to verify a legitimate source MAC address for each packet.

13. You are given a PC, a router, and a cable. Select the correct combination that will allow you to log into router PC1 locally using a terminal emulation program such as HyperTerminal.

1. Connect the PC’s Ethernet port to the router’s Ethernet port using a rollover cable
2. Connect the PC’s COM port to the router’s Ethernet port using a straight-through cable
3. Connect the PC’s COM port to the router’s console port using a rollover cable
4. Connect the PC’s COM port to the router’s console port using a straight-through cable

14. The WAN is migrating from RIPv1 to RIPv2. Which statement is correct about RIP version 2?

1. None of the above
2. It supports authentication
3. It has a lower default administrative distance than RIP version 1
4. It uses broadcast for its routing updates

15. Some of the routers have been configured with default routes. What are some of the advantages of using default routes?

1. The keep routing tables small.
2. They require a great deal of CPU power.
3. They establish routes that will never go down.
4. None of the above

16. RIP version 2 is being used as the routing protocol within the network. What does RIP version 2 use to prevent routing loops?

1. Split horizon
2. CIDR
3. Authentication
4. Classless masking

17. You have a single Class C IP address and a point-to-point serial link that you want to implement VLSM on. Which subnet mask is the most efficient for this point to point link?

1. 255.255.255.240
2. 255.255.255.252
3. 255.255.255.0
4. 255.255.255.248

18. Split horizon has been enabled within the routed network. Which one of the following statements best explains the split horizon rule?

1. Once a route is received on an interface
2. advertise that route as unreachable back out the same interface.Information about a route should never be sent back in the direction from which the original update came.
3. Only routers can split boundaries (horizons) between networks in separate AS numbers.
4. Each AS must keep routing tables converged to prevent dead routes from being advertised across boundaries.
