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 encapsulation type would you use. (ietf) 19. which statement is true regarding full duplex.( allows for transmission and receiving of data simultaneously) 20. purpose of icmp. (send error and control messages) 21. the command that saves the configuration stored in ram to nvram. (copy running-config startup-config) 22. 2 hdlc charcteristics. (supports point-to-point and multipoint, default serial encapsulation) 23. three key features of cdp. (does not require any layer 3 protocols to be configured, verify connectivity, will allow for the discovery of layer 3 addresses on neighbor routers) 24. what is the default ipx ethernet encapsulation. (novell-ether) 25. which osi layer is concerned with path determination. (network) 26. which osi layer is responsible for data presentation, formatting and encryption. (presentation) 27. which command will show all dlci configured. (show frame-relay pvc) 28. which command will set the bandwidth on serial0 to 56k. (router(config-if)#bandwidth 56) gl$1T%9 来 源 于 贵 州学 习网 IT认证思科认证 WWw.gzU521.COm gl$1T%9 29. which command will change the name of the router. (router (conifg)#hostname new name) 30. split horizon never sends information back to the interface, from which it was received. 31. valid lmi types (q933a, ansi, cisco=default) 32. banner motd# is the command to set message of the day, and is displayed at he time of login. if you want to set a message to be displayed at the time someone accesses a specific interface you will use the command description at the interface level. 33. from global configuration mode which command will create sub-interface # 1 for serial 0. (int s0.1 point-to-point) 34. which command enables load balancing over two multiple paths for ipx on a cisco router. (ipx maximum-paths 2) 35. how do you determine which ip access-lists are applied to interface e0. (show ip interface e0) 36. what command will enable igrp on a router. (router igrp autonomous # and to assign an address on the interface level write network class(a,b,c), i.e. router(config-if)#network 158.2.0.0 you don't specify the mask) 37. computer a is transmitting data to computer b and expects an acknowledgment after every 4 packets. after a while the expected acknowledgment increases to 6 packets. this is an example of what. (sliding window) 38. trace is the command that determines the path a packet takes. 39. on a 7500 series router the command format to configure serial interface is int s 1/0/0. first you specify interface that is s in this example then the slot that is 1, then the port adapter that is 0 and then the port that is 0. where as in case of a cisco 5500 switch, the command would be int s 1/0 where 1 is the slot and 0 is the port. 40. stp spanning tree protocol is used to prevent routing loops on a switch and sta is the algorithm created by stp. 41. what does the log parameter in the ipx access-list do. (records the number of times that a packet matches the list). 42. to configure an interface for ppp encapsulation use command router(config-if)# encapsulation ppp and to configure for ppp authentication use the command router(config-if)# ppp authentication chap|pap.   |
