t is as follows: No. of Questions: 78 Passing Score: 755 marks Exam Time: 120 minutes. You can't go back, means what's done is done. Pretty tough Ha! I scored 89.7%. It wasn't as hard as I was expecting it to be. Resources I used to prepare for CCNA Cisco Press Official Course Book. ICRC. The dump from DIAMOND, it's good. Questions I recommend you study are: 1. Identify the command to configure the router to boot from an IOS located on a TFTP server. (boot system tftp IOS filename IP address of tftp server) 2. What IP command would you use to test the entire IP stack. (Telnet) 3. Identify the three characteristics of IPX RIP. (60 sec update, distance vector, uses tics and hop count as a metric) 4. Identify the command to configure all the default vty ports. (Router(config)#line vty 0 4) 5. Identify the command that displays the SAP table. (sh ipx servers) 6. What is the bandwidth of a serial connection. (1.544 Mbps, T1) 7. What is true for two routers running IGRP to communicate their routes. (Same autonomous system number) 8. Maximum numbers of bits that can be borrowed from a class B network. (14 bits, hosts can't be all 1s or 0s) 9. Identify the command which connects access-list 101 inbound to interface e0. (Router(config-if)# ip access-group 101 in, out is default) 10. The command to display the IP host table. (show hosts) 11 Identify three features of IGRP. (updates every 60 sec, composite metric, Poison reverse, default metrics are bandwidth and delay) 12. Command to display IP routing table. (sh ip route) 13. Three methods to prevent routing loops.(Split horizon, Hold down timers, poison reverse) 14. Which OSI layer is responsible for end to end communication, segmentation and re-assembly. (Transport) 15. Administrative distance for RIP and IGRP. (RIP=120, IGRP=100) 16. The range for extended IP access-list. (100-199) 17. Two switching methods. (Cut through: Fast, cause reads only the frame, initiates the destination and forwards the packet. Decreases latency. (latency means delay). Store & Forward: Reads the frame, stores the complete packet in the buffer and then forwards, reliable delivery. Increases Latency.) 18. Configuring a Cisco router to connect to a non Cisco router across a Frame Relay network, which e
