1. (A) and (D)

The AppleTalk protocol works in NT with the Services for Macintosh to support the Apple Mac hosts.

2. (A)

TCP/IP is the universal Internet protocol. It's very efficient for WANs and is a connectionless, routable protocol.

3. (B) and (C)

This would work and be a good solution. NetBEUI is a low-overhead protocol and is fast and easy to configure. It is non-routable, so it works well with small Microsoft networks.

4. (A)

If you are connecting to the Internet, you must use TCP/IP. You can implement IPX/SPX elsewhere on your network and use a proxy server, but you can run a straight IP network if you wish.

5. (D)

SMB is the file-sharing and printer-sharing protocol of Windows NT Operating System.

6. (B)

File Transfer Protocol (FTP) allows you to transfer the file to the UNIX host.

8. (C)

Routers maintain the routing tables to the local and remote networks. You can choose to manually configure the routers, but using RIP, OSPF, or another routing protocol makes the routing table configuration and updates automatic.

9. (D)

ISA come in 8 or 16 bit, MCA cards come in 16 or 32 bit, and EISA are 32 bit. Bus mastering is the fastest memory transfer listed, and is supported on EISA, MCA, and PCI cards. The EISA with bus mastering would give the best performance.

10. (A)

An 8-bit card is not going to provide good performance, and a card that uses Cat 5 cabling will not affect the speed of the network card. A card that supports shared memory transfer would provide better performance than one that uses DMA.

11. (B)

10Base2 transmits at 10 Mbps and is flexible and easy to use, but is not the cheapest method. And unless there is good reason to do otherwise (ie: distance or interference), a new network should be set up using 10BaseT.

12. (B)

The IEEE is responsible for assigning network card addresses. The EIA/TIA created standards for UTP cable, InterNIC is the organization responsible for assigning Internet IP addresses, and AWG is a standard known as American Wire Gauge.

13. (C)

The transceiver on the network adapter card is responsible for converting data to and from serial and parallel forms.

14. (B)

The IRQ is probably conflicting with another device like the sound card. Network cards don't use COM ports. The wrong transceiver setting would prevent network communication, but wouldn't prevent the system from seeing the network card.

15. (D)

The buffer is a portion of RAM that is set aside to hold data.

16. (B)

The default for COM1 and COM3 is IRQ 4.

17. (C)

LPT1 uses IRQ 7

18. (D)

A repeater is used to boost the signal loss caused by attenuation.

19. (D)

By default, COM 1 uses IRQ 4, COM 2 uses IRQ 3, LPT 1uses IRQ 7, and LPT 2 uses IRQ 5.
