Answers
1. | A is correct. End users must have a licensed copy of Windows XP (any version) to install service packs. B is incorrect because both Home and Professional Editions can be used to obtain and install Windows Update files. C is incorrect because registration is optional. D is incorrect because the computer would not function after two years if the product had never been activated. E is incorrect because everyone should install distributed service packs. |

1. | A small office user has a network that consists of four computers. One computer running Windows XP Professional Edition acts as the host and provides ICS services, and the other three computers access the Internet through this host computer’s Internet connection. The administrator of the network wants to protect the network by using ICF. What must the administrator do?

2. | You are troubleshooting a network connection and need to use the Ping command to see if a host is reachable. Which ICMP option should you enable on the host computer?
|
|
Answers
1. | C is correct. Enabling ICF on the host computer is all the administrator needs to do on a network that is already configured and running properly. A and B are incorrect because routers, DSL, and cable modems are not requirements of ICF. D is incorrect because ICF should not be installed on computers that are not directly connected to the Internet. |
2. | B is the correct answer because it allows the host computer to respond to ping requests. A is incorrect because this option passes on information about connected routers and the flow of traffic from the computer. C is incorrect because this option allows the computer to send a message to slow the flow of data. D is incorrect because this option allows routers to redirect data to more favorable routes. |

2. | You work for an Internet service provider (ISP). An end user calls and reports that he has a virus on his computer. He has discovered through his friends and from watching the national news that he has the Blaster worm. He does not have any antivirus software installed. Although it is not your job to assist the user in ridding the computer of the virus, you want to assist in some way in the time you are allotted. List four ways the user can get help in ridding the computer of the virus. |
|
Answers
1. | B is correct. These symptoms are common signs of a virus that is a worm. A is incorrect because simple replicating viruses usually replicate only through e-mail and the network. C is incorrect because viruses can travel in ways other than e-mail. D is incorrect because these are not common signs of a corrupt installation; they are common signs of a virus. |

1. | An end user is setting up a server that he will host himself using his small office network, and he wants Internet users to be able to connect to the Web pages stored on it. He is also setting up an additional server that will permit users to upload and download files using the Internet instead of the local network. Which two services must he enable to permit the required traffic to flow through the ICF he currently has configured on this connection? (Choose two.)

|
Answers
1. | A and B are correct. The Web Server (HTTP) service allows users to access the Web pages stored on the Web server, and the FTP Server service allows users to upload and download files stored on the additional server. C is incorrect because Telnet servers are used to log on to network computers from remote locations. D is incorrect because POP3 servers are used to receive e-mail. |

1. | As a desktop technician for a small office network, it is your job to make sure all the computers on the network are as secure and protected as possible. You have configured Windows Update to obtain and install updates automatically, you have ICF configured on all of the computers that need it, you have antivirus software installed on each computer, you incorporate a router for extra protection, and you enforce password policies that require users to create strong passwords on their computers. You now want to be able to test the computers on the network regularly from your desktop computer and check for additional vulnerabilities as they arise. The computers are all in the IP range of 192.168.0.1 to 192.168.0.12. You want to check the following:
