Exam Prep Questions

     
Question 1

You are the help desk support technician for an Internet service provider. A user calls to report that she is unable to establish a connection. When the user attempts to dial into the ISP, she receives an access denied error message. What should you do?

  • A. Have the user open the Phone and Modem applet to run diagnostics on the modem.

  • B. Tell the user to verify that the cable is securely in place.

  • C. Check the credentials the user is providing.

  • D. Check that the hardware configuration for the modem matches those of the remote access server.

A1:

Answer C is correct. An access denied error message indicates a problem with authentication. One of the first things you should check is that the user is providing the correct username and password. A hardware problem or a problem with the configuration of the modem would result in a different error message. Answer A is incorrect because a different error would appear if it was hardware related. Answer B is incorrect because a connection has been established, but authentication with the server is failing. Answer D is incorrect because the problem is not hardware related .

Question 2

You are the desktop support technician for a small insurance company. The IP-based network hosts approximately 20 workstations. All workstations are members of the same domain. A user on the network reports that he is unable to access any network resources. The problem did not occur the previous day. You have verified that the problem does not exist with the network card or cable. When you issue the ipconfig command, you receive the output shown in the following figure.

What is most likely causing the problem?

  • A. The client is configured with the incorrect IP address of the DNS server.

  • B. The client is unable to obtain an IP address from a DHCP server.

  • C. The network interface card is not functioning.

  • D. A domain controller is not available to authenticate the user.

A2:

Answer B is correct. The figure above indicates that Automatic Private IP Addressing (APIPA) is being used. If a DHCP server is unavailable, DHCP clients self-assign an IP address until the DHCP server is available. Therefore, answers A, C, and D are incorrect.

Question 3

A user reports that she is unable to access resources on another computer. When you use the UNC path to the remote computer, you receive the error shown in the following figure.

The user can successfully access other computers on the network. How should you begin troubleshooting the connectivity problem?

  • A. Replace the network cable to the network adapter.

  • B. Issue the ipconfig command to ensure TCP/IP is properly configured on the local computer.

  • C. Update the device driver for the network card.

  • D. Use the ping command to test connectivity between the two computers.

A3:

Answer D is correct. You can use the ping command to test connectivity between two hosts. You should use this command to verify that the remote computer is responding. If you receive an unsuccessful response, the remote computer may be offline. Because the user can access other computers on the network, you can eliminate the network card or cable as being the cause of the problem. This would also indicate that TCP/IP is properly configured on the local computer. Therefore, answers A, B, and C are incorrect.

Question 4

A user is having problems related to NetBIOS name resolution. You want to purge the contents of the local NetBIOS name cache. Which command must you use?

  • A. ipconfig

  • B. net diag

  • C. nbtstat

  • D. nslookup

A4:

Answer C is correct. You can use the nbtstat command to purge the contents of the local NetBIOS name cache. Answer A is incorrect because ipconfig can be used to view and manipulate IP parameters. Answers B and D are incorrect because neither of these commands allows you to empty the contents of the NetBIOS name cache.

Question 5

You have just updated a static record in the DNS database for Computer1. A user now reports that he is unable to access resources on this computer. You suspect an incorrect mapping in the user's DNS resolver cache. Which of the following commands can you use to purge the contents of the cache on the user's computer?

  • A. ipconfig /renew

  • B. ipconfig /flushdns

  • C. ipconfig /release

  • D. ipconfig /displaydns

A5:

Answer B is correct. Each DNS client maintains a cache of recently resolved hostnames. You can use ipconfig /flushdns to purge the contents of the cache. Therefore, answers A, C, and D are incorrect.

Question 6

A user calls to report that she is unable to establish a dial-up connection with her ISP. You discover that the modem does not make any noise when the user attempts to establish the connection. What two steps should the user perform to begin troubleshooting the problem? Choose two correct answers.

  • A. The user should check that the modem is properly seated in the computer.

  • B. The user should contact the modem's manufacturer for an update.

  • C. The user should verify she is using the correct username and password for authentication.

  • D. The user should check that the phone line is properly connected to the modem and phone jack.

A6:

Answers A and D are correct. Before having the user update the device driver for the modem, have the user check that the modem is properly seated inside the computer and that the phone line is properly connected. If neither method solves the problem, you can then begin looking at reinstalling or updating a device driver. Because the modem is not dialing out, authentication can be eliminated as the cause of the problem. Therefore, answer C is incorrect. Answer B is incorrect. Although this step may be necessary later, other simple troubleshooting steps should be performed first.

Question 7

You are the desktop support technician for a small consulting firm. A user calls to report that he is unable to access a shared folder on another computer. The user is trying to access the share using a mapped drive but receives an error message that the computer is not found. The user can successfully access other computers on the network. How should you troubleshoot the issue?

  • A. Use the ipconfig command to check the TCP/IP configuration of the user's computer.

  • B. Check the user's permission on the shared folder.

  • C. Verify that the user has a network connection.

  • D. Check to see that the remote computer is online.

A7:

Answer D is correct. If the user is unable to connect to the shared folder and is receiving a message that the computer cannot be found, verify that the remote computer is online. Because the user can successfully access other shares on the network, this eliminates TCP/IP and the user's network connection as the source of the problem. Therefore, answers A and C are incorrect. Answer B is incorrect because a permission problem would result in an access denied message.

Question 8

A user is not able to communicate on the network. You have verified that the network adapter installed in the user's computer is on the HCL for Windows XP. You want to check the status of the device to see whether it is functioning correctly. What should you do?

  • A. Open the properties window for the network adapter within Device Manager.

  • B. Open the Phone and Modems Option applet and use the Diagnostics tab.

  • C. Open the Command Prompt window and use the ping command with the loopback address.

  • D. Open the Command Prompt window and use the ipconfig /all command.

A8:

Answer A is correct. By opening the properties window for the network adapter within Device Manager, you can view the status of the device to determine whether it is functioning. Answers C and D are incorrect because these commands are used to diagnose TCP/IP problems. Answer B is incorrect because you use the Diagnostics tab located within the Phone and Modem Options applet to diagnose modem problems.

Question 9

You are the help desk support technician for an ISP. A user calls to report that she is unable to receive email. You determine that the user can successfully send email. However, the user also indicates that she receives a host not found message when attempting to send email. You also have determined that the user can successfully browse the Internet with the dial-up connection. What should you do?

  • A. Have the user ping the IP address of an Internet host.

  • B. Open the properties for the email account and verify the correct spelling of the username.

  • C. Open the properties for the email account and verify that the user has entered the correct name for the POP server.

  • D. Open the properties for the email account and verify the user has entered the correct name for the SMTP server.

A9:

Answer D is correct. An SMTP server is used for sending email. If the user receives a message that the host cannot be found, open the properties for the email account and verify that the user has put in the correct name of the SMTP server. Answer C is incorrect because a POP server is used for receiving mail. The user is not having a problem receiving email messages. Answer B is incorrect. If the user had an authentication problem, a different error message would appear. Answer A is incorrect because you have already established that the user can successfully browse Web pages on the Internet.

Question 10

Two hosts on your network are not able to communicate. You suspect that a problem may exist with one of the routers between the computers. What command can you use to determine which router may be causing the problem?

  • A. ipconfig /all

  • B. tracert

  • C. ping 127.0.0.1

  • D. ipconfig /renew

A10:

Answer B is correct. You can use the tracert command to trace the path a packet will take to reach a destination host. The results tell you if one of the routers is not responding. Answer A is incorrect because the ipconfig /all command enables you to view the IP configuration on a computer. Answer C is incorrect because this command enables you to test whether TCP/IP is initialized on the local computer. Answer D is incorrect because you use this command to renew an IP address obtained from a DHCP server.
