Review Questions

1. 

Which NetWare log file(s) always indicate(s) the time and date at which a failure or an event occurred? (Choose all that apply.)

  1. SYS$LOG.ERR

  2. CONSOLE.LOG

  3. ABEND.LOG

  4. SYS$ERR.LOG

a, c.because both the sys$logt.err and abend.log files log errors that may or may not be critical, it is important that you know when these events occurred. as such, both of these netware log files contain date and time stamps for each event.

2. 

You have a user who cannot connect to the network. What is the first thing you could check to determine the source of the problem?

  1. Workstation configuration

  2. Station link light

  3. Patch cable

  4. Server configuration

b.the link light indicates that the network card is making a basiclevel connection to the rest of the network. it is a very easy item to check and if the link light is not lit, it is usually a very simple fix (like plugging in an unplugged cable).

3. 

A user cannot access the local intranet. Which action will not help you determine how to narrow the problem down to the intranet?

  1. Accessing the intranet from your workstation

  2. Accessing the intranet from the user’s workstation as yourself

  3. Replacing the patch cable on the workstation

  4. Asking another user to access the intranet from the problem user’s workstation

c.replacing the patch cable is a much more difficult troubleshooting step than testing intranet access from different workstations. because workstations are usually grouped together, it would be easier to have many people first try to access at once than to crawl around behind a desk or cubicle to replace a patch cable.

4. 

Several users can’t log in to the server. Which action would help you to narrow the problem down to the workstations, network, or server?

  1. Run tracert from a workstation

  2. Check the server console for user connections

  3. Run netstat on all workstations

  4. Check the network diagnostics

b.although all of these are good tests for network connectivity, checking the server console for user connections will tell you if other users are able to log into the server or not. if they can, the problem is most likely related to one of those users workstations. if they can t, the problem is either the server or network connection. this helps narrow down the problem.

5. 

Without a ______________________________________, you may not be able to perform 100 percent of the network diagnostics for a network card.

  1. Hardware loopback

  2. Patch cable

  3. Crossover cable

  4. Protocol analyzer

a.a hardware loopback is either a cable or plug that you attach to the network interface on a nic. the loopback connects nic outputs to that nic s inputs so that you can test the transmission and reception capabilities of the nic. without a hardware loopback, you can t run the full batch of tests in the nic s diagnostics program (since a transmission test is usually part of this batch of tests).

6. 

A user can’t log in to the network. She can’t even connect to the Internet over the LAN. Other users in the same area aren’t experiencing any problems. You attempt to log in as this user from your workstation with her username and password and don’t experience any problems. However, you cannot log in with either her username or yours from her workstation. What is a likely cause of the problem?

  1. Insufficient rights to access the server

  2. A bad patch cable

  3. The server is down

  4. Wrong username and password

b.because of all the tests given and their results, you can narrow the problem down to the network connectivity of that workstation. and because no other users in her area are having the same problem, it can t be the hub or server. you can log in as the user from your workstation, so you know it isn t a rights issue or username/password issue. the only possible answer listed is a bad patch cable.

7. 

A user is experiencing problems logging in to a Unix server. He can connect to the Internet over the LAN. Other users in the same area aren’t experiencing any problems. You attempt logging in as this user from your workstation with his username and password and don’t experience any problems. However, you cannot log in with either his username or yours from his workstation. What is a likely cause of the problem?

  1. The Caps Lock key is pressed.

  2. The network hub is malfunctioning.

  3. You have a downed server.

  4. You have a jabbering NIC.

a.because other users in the same area aren t having problem, it can t be a downed server, network hub, or jabbering nic. and because both you and the user can t log in, more than likely it s a problem specific to that workstation. the only one that would affect your ability to log in from that station is the caps lock key being pressed. that will cause the password to be in all uppercase (which most server oses treat as a different password) and will probably be rejected.

8. 

Which technical support resource has the most current information and up-to-date drivers and patches?

  1. README file

  2. Technical support CD-ROM

  3. Technical support website

  4. Technical phone support

c.a vendor s technical support website usually has the most current information because the information can be distributed immediately. most vendors have moved to using a technical support website as opposed to a cd-rom, because it s much cheaper and users prefer it.

9. 

You are troubleshooting your only PC at home at 11:30 on a Sunday night, but you are having trouble connecting to the Internet. You suspect that the modem needs a new driver. Which technical support resource could you possibly use to get the new driver?

  1. README file

  2. Technical support CD-ROM

  3. Technical support website

  4. Technical support phone support

b.of those options listed, the only place to get a driver is the technical support cd-rom or driver cd-rom that comes with the modem. you could normally get it from the internet, but your internet connection is not functioning and you can t call tech support because it s after most tech support s normal business hours.

10. 

Your NetWare 5 server suddenly experienced an error. It then started the shutdown procedure, and the error scrolled off the screen. You didn’t have CONLOG.NLM loaded when this happened. Next to the command prompt on the console, there was a number in angle brackets, like this: <2>. Which log file could you look in to determine the source of the problem and the error message that was displayed?

  1. BOOT.LOG

  2. ABEND.LOG

  3. SYS$LOG.ERR

  4. SYS$ERR.LOG

b.the conditions described indicate that the netware server experienced an abend. when this happens, a netware 5 server will write the abend error and the conditions under which the abend occurred to the abend.log file. so, of those listed, the best place to look would be the abend.log file.

11. 

A user calls you, reporting a problem logging in to the corporate intranet. You can access the website without problems using the user’s username and password. At your request, the user has tried logging in from other workstations unsuccessfully. What is the most likely cause of the problem?

  1. The user is logging in wrong.

  2. The network is down.

  3. The intranet server is locked up.

  4. The server is not routing packets correctly to that user’s workstation.

a.because the user can t log in correctly from any machine, more than likely he is using the wrong procedure for logging in. because no one else is having that problem (including yourself), the problem must be related to that user.

12. 

A user calls you reporting a problem logging in to the corporate intranet. You cannot access the website using the user’s username and password, but you can access it when logging in with your username. At your request, the user has tried logging in from other workstations, but without success. What is the most likely cause of the problem?

  1. The user is logging in wrong.

  2. The user’s workstation is misconfigured.

  3. The intranet server is locked up.

  4. The user doesn’t have the correct rights.

d.because you cannot log in with the user s password from your machine or from any other machine, the problem is most likely related to that particular username. the only answer listed that is specific to the username is that the user doesn t have the correct rights.

13. 

Which software-troubleshooting tool could you use to determine which protocol is configured with the wrong address?

  1. Performance-monitoring tools

  2. Protocol analyzer

  3. Antivirus checker

  4. Protocol-layer monitor

b.a protocol analyzer is a software tool that can be used to examine the details of packets as they travel across the wire. using this kind of tool, you could examine the addresses of packets as they cross the wire and see which station is configured incorrectly.

14. 

Which hardware-troubleshooting tool(s) could you use to find out where a cable is routed? (Choose all that apply.)

  1. Crossover cable

  2. Hardware loopback

  3. Tone generator

  4. Tone locator

c, d.a tone generator and tone locator can help you find out where cables are routed. the tone generator sends a signal down the wire. the tone locator is run along a wire to test if it contains the signal. using this tool, you can tell where a cable (the cable that you attach the tone generator to) is running and what path it takes.

15. 

Which Windows NT log file keeps track of all events, such as log in/log out and use of rights?

  1. Security

  2. System

  3. Application

  4. Console

a.the security log file in the event viewer logs all security-related events, including authentication, rights application, and breaches of those security methods. each time some kind of security event occurs, the item is written to the security log file.

16. 

Which Windows NT utility do you use to manage the major Windows NT log files?

  1. Log File Manager

  2. Event Viewer

  3. User Manager

  4. Server Performance Monitor

b.the event viewer is the windows nt utility used to manage the major nt log files (system, security, and application). it is an application that is installed with each installation of windows nt (start programs administrative tools event viewer).

17. 

A user calls you, complaining that he can’t access the corporate intranet web server. You try the same address, and you receive a Host Not Found error. Several minutes later, another user reports the same problem. You can still send e-mail and transfer files to another server. What is the most likely cause of the problem?

  1. The hub is unplugged.

  2. The server is not routing protocols to your workstation.

  3. The user’s workstation is not connected to the network.

  4. The web server is down.

d.because other people are experiencing the problem, most likely the problem is either network- or server-related. and because you can transfer files to and from another server, it can t be the network. thus, the problem is related to the web server.

18. 

You are connecting a cubicle farm to your network. You install NICs in all the workstations and run cables to a workgroup hub. You then connect the MDI port on the workgroup hub to the main hub with a standard patch cable. Upon powering up the cubicle farm computers, none of them can see the servers on the network. What could you replace to solve this problem?

  1. Hub patch cable

  2. Workstation patch cables

  3. Server patch cables

  4. Workgroup hub

a.the mdi port was designed to uplink one hub to another using a crossover cable. by putting in a standard patch cable, you prevent the hubs from communicating, thus the workgroup cannot communicate with the servers.

19. 

A user from the accounting department calls complaining that she can’t see any servers on the network or log in. Her computer operates fine otherwise. No other users from the accounting department are reporting any problems. What is the first thing you could check?

  1. Patch cable quality

  2. Link lights

  3. Power cables

  4. Server status

b.the link lights will tell if the computer can communicate with the rest of the network. although you could check all of these items for this problem, trying the link light(s) on the nic in the workstation and hub to make sure they can communicate is the first thing to do because it s the simplest.

20. 

Several users have complained of the server’s poor performance as of late. You know that the memory installed in the server is sufficient. What could you check to determine the source of the problem?

  1. Server’s NIC link light

  2. Protocol analyzer

  3. Performance-monitoring tools

  4. Server’s System Log file

c.performance-monitoring tools can give an idea of how busy the server and the rest of the network are. these tools use graphs to indicate how much traffic is going through that server.
