What typically happens when a Cisco router network is being rolled out is that a base configuration for all routers is defined, and has the modified IP addresses for each location It makes life easier if this base configuration can be loaded into each router from a network server each time a new router is installed It is more time-efficient to modify an existing configuration than to create one from scratch There is a simple way to achieve this, using any machine that can act as a TFTP (Trivial File Transfer Protocol) server Many of the more full-featured TCP/IP stacks available commercially provide TFTP server functionality Any Unix machine also can act as a TFTP server TFTP is a simple file transfer protocol that is not as complex or as fully functional as FTP TFTP has little in the way of security, user authentication, or end-to-end reliability, because it uses UDP rather than TCP as the layer 4 protocol Let's look at setting up a Unix machine as a TFTP server, saving the configuration file of a router to this TFTP server, and then reloading the configuration

9 Which of the following is the most reliable indicator that a network server could be overloaded A The activity light on the network card is constantly lit B Performance Monitor shows network requests are backing up in the queue C Network Monitor shows too many packets are leaving this server D The computer is very slow to respond when you log on 10 Which of the following is not a good recommendation when it comes to performing a baseline of your network A Monitor traffic at different times of the day B Configure the snapshots to take place at midnight each night C Monitor traffic for days, even weeks D Take as many traffic snapshots as possible

11 You feel you are having driver incompatibility problems with your network adapter What is the best resource for finding another network adapter driver A TechNet B Resource kit C Vendor web site D Documentation CD 12 You are instructed to migrate the DHCP service from a Windows NT 40 server to a Windows 2000 server What is the best resource to begin preparing for the migration A A Windows magazine B Telephone tech support C Vendor CDs D Resource kits 13 You are experiencing lockup problems with a new version of the virus-scanning utility that you just implemented Which of the following is probably not needed when you open a technical support incident A The version of affected software or hardware B The number of users on the network C Troubleshooting steps taken so far and their results D Current operating system

The last field in the SPX header before the Data field is the Allocation field The value in this 16-bit field represents the number of listen buffers available in one direction on the connection Because the unavailability of listen buffers would cause new packets to be lost, SPX can only transmit packets until the Sequence Number equals the value of the remote Allocation Number

14 You have a user receiving the error message, A domain controller cannot be found Assuming that no one else has called you with this error, which of the following is not likely to be the problem A The TCP/IP configuration is not correct on the computer B The domain controller could be down C The network card is not functioning correctly D A cable might be faulty or not plugged in 15 Which of the following is not likely to be an abnormal condition on a network A It takes a long time to print a large document that contains images B It takes longer to become authenticated C Users are having problems connecting to the SQL database D You continually lose connection to the mainframe 16 Which of the following will you not need prior to installing DNS A The DHCP address scope B Your domain name C The hostnames of each server D The IP address of each server for which you want to provide name resolution 17 Which of the following is not true regarding WINS A It resolves NetBIOS names to IP addresses B You must replicate with all other WINS servers C You must manually enter the address mappings D WINS dynamically updates the WINS database
