13. Encryption techniques คือข้อไหน

1) Single key, public key & Digital signature

3) Public key, Private key & Digital signature

5) Private key & Digital signature

15. A backbone network is a:

1) High-speed central network that connects other networks in a distance spanning to several miles.

2) Group of personal computers connected to a common communication circuit that is able to exchange information.

3) Network spanning a geographic area that encompasses a city or county (3 to 30 miles).

4) Network that connects servers and storage devices in server room or small data center.

5) Network spanning a large geographical area (up to 1000s of miles).

25. Which of following layer is (are) part(s) of backbone?

5) All of 1, 2, 3, 4 are correct

30. A peer-to-peer LAN:

3) is generally cheaper in hardware and software than a dedicated server

1) has more capability than a dedicated server

2) supports a higher number of computers than a dedicated server

4) is not appropriate for sharing resources in a small LAN

5) is often much faster than dedicated server networks

33. Client-server architectures:

3) can use middleware to provide a standard way of communicating between software from more than one vendor

1) cannot connect computers that use different hardware

2) one of the least used network architectures today

4) assign the responsibility for the presentation logic to the server

5) were the earliest type of network architectures

34. Media access control:

1) is not very important in point-to-point with full duplex configuration

2) is not very important in local area networks

3) is not very important in a point-to-point with a half-duplex configuration

4) is not very important in a multipoint configuration

5) does not control when computers transmit

2) performs packetizing, as well as routing and addressing functions

1) is the least commonly used network protocol for LANs because it cannot be combined with Ethernet

3) is not very efficient and is prone to errors

4) is compatible with only one type of data link protocol, SDLC

5) refers to Telephone Control Procedures/Inter-exchange Procedures

38. Advantage of N-tiered architecture:

1) is generally more “scalable” than a three-tiered architecture

2) is generally less “scalable” than a three-tiered architecture

3) uses only two sets of computers in which the clients are responsible for the application and presentation logic, and the servers are responsible for the data

4) uses exactly three sets of computers in which the client is responsible for presentation, one set of servers is responsible for data access logic and data storage, and application logic is spread across two or more different sets of servers

5) puts less load on a network than a two-tiered architecture because there tends to be less communication among the servers

42. Which of the following is not a problem with dialed circuits?

5) Use of these circuits is very simple.

1) Data transmission rates on dialed circuits are relatively low.

2) Dialed circuits may vary in quality.

3) Transmission rates for dialed circuits can vary with each call.

4) It is hard to predict if a given connection will be clear or noisy.

43. Which of the following is not an example of identifying protocols that are needed to support hardware and software requirements of applications that will use the network?

5) an application will have drop down menu choices

1) an application will use HTTP over TCP/IP

2) an application will run on an IBM mainframe and so the network will require SNA traffic

3) an application will need a gateway to translate SNA traffic into TCP/IP protocols

4) an application will use SPX/IPX with a Novell file server

45. One reason that there are technical network integration management issues is the fact that:

1) The more different types of network technology used, the more complex network management becomes.

2) Internet protocols are very similar to traditional mainframe protocols.

3) Each LAN was developed by a centralized group.

4) All LANs used in an organization all use the same architecture.

5) All LANs used in an organization use the same type of technology.
