Erouting v4.0 Chapter 2Posted by Santhosh Kumar Wednesday, February 18, 2009Expect minimum percentage: 100%1. Refer to the exhibit. Given the output in the exhibit, how would a clock rate be determined for this link?ans:The rate configured on the DCE determines the clock rate2. Which piece of information is available from examining the output of the command show ip interface brief?ans:Interface IP address3. Refer to the exhibit. Which set of commands will configure static routes that will allow the WinterPark and the Altamonte routers to deliver packets from each LAN and direct all other traffic to the Internet?ans:WinterPark(config)# ip route 0.0.0.0 0.0.0.0 192.168.146.1Altamonte(config)# ip route 10.0.234.0 255.255.255.0 192.168.146.2Altamonte(config)# ip route 0.0.0.0 0.0.0.0 s0/14. The output of the Router# show interfaces serial 0/1 command displays the following:Serial0/1 is up, line protocol is down.What is the most likely cause for the line protocol being down?ans:No clock rate has been set5. Which two statements describe functions or characteristics of CDP? (Choose two.)ans:It starts up automatically and allows the device to detect directly connected neighbor devices that use CDPIt allows systems to learn about each other even if different network layer protocols are configured.6. What happens to a static route entry in a routing table when the outgoing interface is not available?ans:The route is removed from the table.7. What happens to a static route entry in a routing table when the outgoing interface is not available?ans:The route is removed from the table8. The routers in the diagram use the subnet assignments shown. What is the most efficient route summary that can be configured on Router3 to advertise the internal networks to the cloud?ans:192.1.1.0/259.Refer to the exhibit. What is the significance of the /8 in the route to the 10.0.0.0 network?ans:It indicates the number of consecutive bits, from the left, in the destination IP address of a packet that must match 10.0.0.0 to use that route10. A router has one static route configured to each destination network. Which two scenarios would require an administrator to alter the static routes that are configured on that router? (Choose two.)ans:The destination network no longer exists.A topology change occurs where the existing next-hop address or exit interface is not accessible.11. Refer to the exhibit. A company network engineer is assigned to establish connectivity between the two Ethernet networks so that hosts on the 10.1.1.0/24 subnet can contact hosts on the 10.1.2.0/24 subnet. The engineer has been told to use only static routing for these company routers. Which set of commands will establish connectivity between the two Ethernet networks?ans:R1(config)# ip route 10.1.1.0 255.255.255.0 192.168.0.2R2(config)# ip route 10.1.2.0 255.255.255.0 192.168.0.112. What two devices are responsible for converting the data from the WAN service provider into a form acceptable by the router? (Choose two).ans: a modema CSU/DSU device13.Which of the following is true regarding CDP and the graphic shown?ans:By default, Router A will receive CDP advertisements from routers B and C.14. Refer to the exhibit. How will packets destined to the 172.16.0.0 network be forwarded?ans:Router1 will perform recursive lookup and packet will exit S0/0.15. Refer to the exhibit. What two commands will change the next-hop
