Chapter 1 Practice Test Answers 1. B. The key term here is sharing. When computers are networked together, they can share their data files, hardware, and software with other users of the network. 2. B. LANs may be confined to one building or several buildings in a small geographical area. 3. C. In a stand-alone environment, workers must resort to sneaker-netting, or copying files onto external or removable media, such as a floppy or Zip disk, and passing the disk from one computer to another. 4. D. Servers run a network operating system such as Microsoft Windows 2000 Server, Microsoft Windows NT Server, Novell NetWare, or UNIX. 5. A. Bus networks generally use coaxial cabling. 6. C. The star is the most common topology in use today. 7. D. In a peer-to-peer network, all computers are considered to be peers, or equal members, participating in the network. 8. A. A single token travels around the ring. . 9. C. In a client-server configuration, one or more servers have centralized control of security. A server is a high-powered computer that runs a network operating system such as Windows 2000 Server, Novell NetWare, or UNIX. A network administrator is responsible for creating user and group accounts, assigning passwords, and controlling the type of access required of the user. 10. A. WAN links are commonly used to connect two or more LANs together. 11. C. Mesh topologies can be quite complex to install and manage. For every node on the network (n), you will have n(n-1)/2 connections. For example, if your network contains 20 computers, you will have 190 connections. 12. C. The Internet is the largest WAN in use today. 13. A. In the star topology, each node uses its own cable to connect to a central device known as a multistation access unit (MAU). The MAU is typically a switch or a hub. 14. B. Devices such as portable computers or portable digital assistants (PDA) use ad hoc mode by connecting directly to each other without using an access point (AP). 15. D. Since each node is involved in the passing process and maintains the ability to regenerate the token, the token passing topology is considered an active topology. 16. D. WANs typically use telephone lines for a public carrier, along with one or more routers, to facilitate network communications. 17. C. The wire connected to the rear of the wall jack runs to a patch panel. 18. A In the ring topology, data packets are seen by all of the nodes on the network. 19. D. In a mesh topology, every node has a path or connection with every other node. This redundancy allows for a high level of fault tolerance on a network. 20. C. One or more network administrators is responsible for creating user and group accounts, assigning passwords, and controlling the type of access required of the user.
