16 CHAPTER 1 Network Fundamentals Top Five Toughest Questions 1. A new intranet has been created in your organization, and it includes a File Transfer Protocol (FTP) site to download files and a news server for sharing information. The network is internetworked with a network belonging to a subsidiary of the company. The subsidiary’s network uses Apple computers and uses AppleTalk as a network protocol. To access the intranet, which of the following protocols would need to be installed on your computer A. IPX/SPX B. NWLink C. TCP/IP D. AppleTalk 2. Your company’s network is on several floors of a building. Because of the amount of data being stored, there are three file servers, a Web server for the intranet, an e-mail server for internal e-mail, and an SQL Server that is used for several databases that have been developed in house. Because of security reasons, floppy disks and other devices to transfer or transmit data to and from the computer have been removed and aren’t permitted. What type of network model is being used A. Client/server B. Peer-to-peer C. MAN D. PAN 3. A company has multiple offices that are internetworked. Office A has a single computer that has the capability to dial into the Internet but isn’t connected to the other offices. Office B is in another part of the country from the other offices but doesn’t have its network interconnected to the other offices. Offices C and D are in separate states but have a dedicated connection between them. Office C has 20 computers that access each other’s machines and provide services and data to one another. Office D has 50 computers that log onto the network using a single server. Based on this information, which of the Offices are part of a LAN and a WAN A. Offices A and B B. Offices B and C C. Offices C and D D. The entire network (Offices A, B, C, and D) 4. You receive a call that the network is down. In this network, all the computers are connected together using a single cable, which they are connected to using T-connectors. Looking at the situation, you find that there is no break through the trunk. Which of the following is most likely the cause of the problem A. A failed network card B. One of the computers is turned off C. T-connectors are missing from the ends of the cable D. Terminators are missing from the ends of the cable
Network Types 17 5. Your network has 10 computers that are networked together using a star topology. Which of the following is a possible point of failure for this topology that could bring down the entire network A. Cable B. Network card C. T-connector D. Hub Answers 1. Correct answer and explanation: C. TCP/IP. Intranets use the same technologies as the Internet, which uses TCP/IP. To access an intranet using a Web browser, and fully take advantage of the services it provides, you would need to have TCP/IP installed just as you would if you were going to access the Internet. Incorrect answers and explanations: A, B, and D. Answer A is incorrect because IPX/SPX is a protocol used on Novell NetWare networks but isn’t a protocol that’s used to access Internet sites (such as FTP sites that require TCP/IP). Although IPX/SPX was a default protocol for NetWare, recent versions use TCP/IP as a default protocol. Answer B is incorrect for similar reasons, as NWLink is an IPX/SPX compatible protocol that’s used by Microsoft operating systems to connect to NetWare networks. Answer C is incorrect because AppleTalk is used for Apple networks but isn’t the protocol used by various Internet technologies (such as FTP Sites). 2. Correct answer and explanation: A. Client/server. A decentralized network model has network resources and administration distributed throughout the network. Administration is shared by designating responsibility to system administrators or individual users, while resources such as servers and other devices are installed at various locations throughout the network. By sharing administrative burdens in this way, certain resources can now be managed by other members of the organization. Incorrect answers and explanations: B, C, and D. Answer B is incorrect because servers are being used, so this isn’t a peer-to-peer network. On a peer-to-peer network, computers on the network are equal and aren’t in the role of dedicated servers. Answers C and D are incorrect because these aren’t network models and are types of networks. Because the network doesn’t extend across a metropolitan area, it isn’t a MAN, and because personal devices aren’t being used to network with computers or other network devices, it isn’t a PAN. 3. Correct answer and explanation: C. Offices C and D. Both these offices have LANs. Office C has a peer-to-peer network, while Office D has a client\server network. They are interconnected to one another and thereby part of a WAN. Incorrect answers and explanations: A, B, and D. Answer A is incorrect because Office A doesn’t have a network but only an Internet connection.
