Part 4 Network Support Quiz



  • Question #1
  • Which of the following security scenarios is the most restrictive?

  • A. Share level access
  • B. User level access
  • C. None of the above
  • D. Make everyone an Administrator


  • Answer: B

  • Explanation:
  • User level security is more granular that share level security. Furthermore, as user level security implements centralized security which enables a more restrictive network wide security approach.

  • Question #2
  • Maria, who works in the finance department, calls you and states that she cannot print to the network printer. She is member of a group who has the correct permissions to print. However, all other users of the same group can print to the printer. What is the problem?

  • A. Her user access permissions are set wrong
  • B. Her printer domain is set wrong
  • C. Her share access is set wrong


  • Answer: A

  • Explanation:
  • To be able to print you must have print permission (access permission) to the printer.
  • The term printer domain does not apply.
  • Share access permissions are used to configure permissions for folders and files that are shared, and not for sharing printers.

  • Question #3
  • What utility can you use to troubleshoot an HTTP server?

  • A. PING
  • B. TDR
  • C. Telnet
  • D. NBTSTAT


  • Answer: C

  • Explanation:
  • Telnet can be used to connect to a HTTP server. With telnet you can issue local commands on the HTTP server which could aid you in troubleshooting.
  • PING can be used to test connectivity to a server. You could test connectivity to the HTTP server, but this is not actually troubleshooting the HTTP server.
  • A time domain reflectometry(TDR) is used to test network cabling.
  • Nbtstat.exe is a Windows command-line program that displays information about the NetBIOS over TCP/IP connections that Windows uses when communicating with other Windows computers on the TCP/IP LAN. This would not be useful in troubleshooting an HTTP server however.

  • Question #4
  • You receive a call from a user working from a virtual office at home. The office is connected to the corporate site using ADSL through a local ISP. All of the light on the external DSL modem indicate that it is connected to the CO. A reboot of the modem indicates a normal reconnect to the CO. However, the user is not able to connect to the Internet? What is the possible DSL problem?

  • A. The user's phone line is busy.
  • B. The DSL access multiplexer is down.
  • C. The DSL filter is connected to the modem.
  • D. The ISP connection to the DSL access multiplexer is down.


  • Answer: D

  • Explanation:
  • Your ADSL modem has a valid connection to the CO. There must be a problem betweenthe CO and the ISP.
  • CO (Central Office) is where the other end of your copper phone line goes to. The length of this copper limits your ability to get DSL and at what speed you can connect. The CO is a Building where the phone switching equipment lives.

  • Question #5
  • You are assisting your senior technician in extending the Demarc for a new DSL circuit. Which tool should you use?

  • A. multimeter
  • B. optical tester
  • C. punch down tool
  • D. bit error rate tester


  • Answer: C

  • Explanation:
  • The Demarc is a connection point between the local network and the Telco network. Extending the Demarc is to physically connect the local network with the Telco network. A punch down tool could be of use.

  • Question #6
  • Before being moved to a new network with Internet access, a user was able to log in to the main Windows NT server and access the Internet. The user is now unable to access the Internet or the file server. What is the problem?

  • A. IPX needs to be installed on the workstation.
  • B. DLC needs to be installed on the workstation.
  • C. DHCP needs to be disabled and a static IP address needs to be assigned.
  • D. NetBEUI automatic configuration needs to be disabled and a static NetBEUI address needs to be assigned.


  • Answer: C

  • Explanation:
  • Correct IP address assignment required to gain access to the Internet. IP configuration is either obtained dynamically from DHCP server or configured statically.

  • Question #7
  • A user is able to access the Internet and departmental drives, but is unable to see the home directory. You verify that the user directory is located at the appropriate server location. What is the most probable cause?

  • A. The user is not logged in to the domain.
  • B. The directory location has been unmapped in the user's profile.
  • C. The user has logged on to the network with the wrong password.
  • D. The network cable between the user's workstation and the flex point is bad.


  • Answer: B

  • Explanation:
  • The user has access to the local network as he can access the departmental drives, which most likely are part of the network. Furthermore, the problem is just that he can't see that home directory. We just need to remap it or browse for it.

  • Question #8
  • A new workstation has been installed in the network. The user regularly uses a Novell 3.11 server. The user cannot access the Internet. Which protocol is NOT installed on the workstation?

  • A. IPX
  • B. DLC
  • C. TCP/IP
  • D. NetBEUI


  • Answer: C

  • Explanation:
  • Internet access required the TCP/IP protocol.

  • Question #9
  • A contractor added a DHCP server to your 200-node network. The contractor was instructed to use the same range of address that was being used previously. You are able to make manual changes to most of the machines, but some machines are in locked areas. Which error messages should you expect to see on those machines?

  • A. IP address conflicts
  • B. IPX address conflict
  • C. NIC address conflicts
  • D. Server address conflicts


  • Answer: A

  • Explanation:
  • In this scenario we are migrating a network from static IP addresses to dynamic IP addresses. The same IP address range should be used. If we keep some static addresses the DHCP server could at some point lease an address that already is in use. This would result in an IP address conflict. A DHCP server automates IP configuration of computers.

  • Question #10
  • Your company is moving into a new building. The cabling company has labeled all 10BaseT jacks for the workstation. However, when you plug in a workstation to a jack and plug the patch cable from the patch panel to the hub, you do not get a link light on the NIC or the hub. You have tried to replace both patch cables with known, good patch cables. It still does not work. What should you do next?

  • A. Hook a protocol analyzer to the hub.
  • B. Reinstall the network interface card driver.
  • C. Test the cable from wall jack to patch panel.
  • D. Replace the workstation patch cable with a crossover cable.


  • Answer: C

  • Explanation:
  • We should analyze the cable. It could be the cause of the problem. It seems likely that this is a physical problem, not a network configuration problem. It seems likely that this is a physical problem, not a driver problem. A crossover cable should not be used between the PC and the wall jacket. Crossover cables are used to connect two similar devices, for example two hubs, or two PCs.

  • Question #11
  • Prior to any new network implementation, which two procedures need to be implemented? (Choose two.)

  • A. Compile documentation
  • B. Disable network logins
  • C. Implement network load balancing
  • D. Determine needs and expectations


  • Answer: A and D

  • Explanation:
  • Solid documentation of the network implementation will be beneficial later on. Needs and expectations should always be considered before implementing a network. In general, it is not necessary to disable network logins. Load balancing is only required to increase performance.

  • Question #12
  • You have a permanent connection to the Internet for your network. Your local network includes a Web server and an SMTP server. You are concerned about the threat of hackers gaining access from the Internet. You have enforced HTTPS access to your Web server. After you make this change, your Web server is no longer accessible from the Internet, but can still be accessed by your internal network users. What would you predict is causing this problem?

  • A. Your DNS server is down.
  • B. Your Web server address has changed.
  • C. Your Internet router is blocking port 389.
  • D. Your Internet router is blocking port 443.


  • Answer: D

  • Explanation:
  • HTTPS (the SSL protocol) use port 443. The router might be blocking this port.
