ould you do to improve the network perfomance? a.replace the server with a multiprocessor computer b.install additional RAM in the server c.install disk strippiing with parity on the server d.segment the network by adding another adapter on the server ans:d 87.In the past year ,you have added 55 client computors to you 10BaseT Ethernet network.users on the jnetwork reports that network response is slow during peak hours of usage. Which solution es the most economical? a .replace with FDDI b.replace with ethernet switchs:low costs: c.replace with 100Mbps ATM d.replace with 10-Mbps token-ring ans:b 88.Current network configratiohn: SERVER27,RUN WINDOWS NT SERVER CLIENTS750 PROTOCOLS NETBEUI ,NWLINK.TCP/IP You add a new client computer to the network,which use nwlink ipx,you are not able to access to some of the shared network resources from the new computer.All of the other computer on the network are able to connect to all the resource. What is the most likely cause of the problem? a.the subnet mask setting on the new client computer, b.there is a protocol mismatch between the new client computer with some of the server. c.the netbios name of the new client computer is the same with the server it cannot connect to. ans:b 89.you are the administrator of a 20 computer Ethernet network.Sometimes 1 or 2 computors are not able to access network resources. the problems have been occured on every computer randomly times.Some of the cable is RGB58 /U SOLID CORE COAXIAL CABLES, and some are RGB58 A/U STRANDED CORE COAXIAL CABLES.You use a Volt-ohmerter to measure the resistance between the center core and the shield on the cable.on T-connecters,and the temminitor.you obtain the following data: RGB58-A/U COAXIAL CABLE :(ohms) BOTH -CONNECTERS(Tohms) : BOTH TERMINATORS:(ohms) 50 What must you do to repair the network? a.replace the 50 ohms terminator with 25 ohm termenator b.replace RGB58-/U CABLE withRGB58-A/U CABLE c.replace RGB58-/U CABLE withRGB62 /U CABLE d.replace T-connecter with new ones. ans:b 90.The users on your network compolained about the slow perfomance on the 500-network .you suspect that a networkadapter card are generating large mount of traffic.Which tool could you use to detect it: a.tdr b.volt-ohmeter c.otdr
