SHORT ANSWER

 

1. What is an advantage and a disadvantage of having multiple LAN protocols on a network?

 

ANS:

An advantage of having multiple LAN protocols on a network is that such a network can perform many different functions on the same LAN, such as enabling Internet access and access to mainframe computers and servers.  The disadvantage is that some protocols operate in broadcast mode, meaning that they frequently send out packets to identify devices on the network, causing a significant amount of redundant network traffic.

 

PTS:   1                    REF:   213

 

2. In general, LAN protocols must provide what four functions?

 

ANS:

In general, LAN protocols must provide:

1. Reliable network links
2. Relatively high speeds
3. Source and destination node address handling
4. Adherence to network standards, particularly the IEEE 802 standards

 

PTS:   1                    REF:   213

 

3. What does the term binding mean?  How does it relate to protocols?

 

ANS:

Network protocols communicate with the NIC in a computer via a process called binding.  Binding a protocol to a NIC enables that NIC to efficiently interface with the network medium.  Binding is using software links in a network operating system to tie together network drivers, protocols, and a computer’s NIC to achieve efficient network communications.

 

PTS:   1                    REF:   218

 

4. Discuss two disadvantages of NetBEUI.

 

ANS:

Two disadvantages of NetBEUI are:

1. It cannot be routed. This is a major disadvantage for medium-sized and large networks.  A NetBEUI packet cannot be forwarded by a router from one network to another, because there is not enough information in the NetBEUI frame to identify specific networks.
2. There are few network analysis tools for NetBEUI other than those provided by Microsoft.

 

PTS:   1                    REF:   222

 

5. Discuss how the NetBEUI protocol corresponds with various layers of the OSI model.

 

ANS:

The NetBEUI protocol corresponds with several layers of the OSI model.  It uses the Physical and Data Link layers for network interface communications.  Within the Data Link layer, it uses the LLC and MAC sublayers for such tasks as flow control of frames and encoding frames.  It also performs functions corresponding to the Transport and Session layers, including insuring the reliability of transmissions, acknowledging transmissions, and establishing and ending sessions.

 

PTS:   1                    REF:   221

 

6. What does it mean to say that AppleTalk is a peer-to-peer network protocol?

 

ANS:

To say that AppleTalk is a peer-to-peer network protocol means that it is designed to enable Macintosh workstations to communicate regardless of the presence of a server.

 

PTS:   1                    REF:   222

 

7. What are the three basic services included in AppleTalk?

 

ANS:

The three basic services included in AppleTalk are:

1. Remote access to network files via the AppleShare File Server application (in conjunction with the AppleTalk Filing Protocol).
2. Printing services through the AppleShare Print Server application (which uses the Name Binding Protocol and the Printer Access Protocol).
3. File services to DOS- and Windows-based systems via the AppleShare PC application.

 

PTS:   1                    REF:   223

 

8. List three advantages of TCP/IP.

 

ANS:

Advantages of TCP/IP are:

1. It is used on most networks and the Internet, which makes it the international language of network communications.
2. There is a wide range of network devices designed for use with TCP/IP.
3. Most computer operating systems now use TCP/IP as their main protocol.
4. There are many troubleshooting and network analysis tools available for TCP/IP.
5. There is a larger body of network professionals who understand TCP/IP.

 

PTS:   1                    REF:   227

 

9. Discuss the advantages and disadvantages of SNA.

 

ANS:

SNA has both advantages and disadvantages.  In terms of advantages, SNA has been available for over a quarter of a century and provides reliable and tested communications with IBM systems.  A significant disadvantage is that SNA is a proprietary protocol suite that requires special devices and complex training to configure, manage, and troubleshoot.  For these reasons, an SNA network with IBM mainframe systems typically runs very well, but at a higher cost for training, personnel, and support.
