Which WAN Technology Provides a Guaranteed Throughput Rate?

Which of the following WAN technologies provides a guaranteed throughput rate?

A.

DSL

B.

T-1

C.

Cable broadband

D.

Dial-up.

B.

Of the WAN technologies listed, only T-1 provides a guaranteed throughput rate. A T-1 line is a dedicated, point-to-point circuit that provides a maximum throughput rate of 1.544 Mbps. This means that the bandwidth available on a T-1 line is fully dedicated to the customer and does not fluctuate depending on network traffic or other factors.

DSL, cable broadband, and dial-up are all shared-bandwidth technologies, meaning that the bandwidth available to the customer varies depending on network usage and other factors. For example, DSL customers may experience slower speeds during peak usage times or if they are located far from the telephone exchange. Cable broadband customers may experience slower speeds if many users in their area are also using the same cable network. Dial-up connections have very low throughput rates and are not typically used for high-bandwidth applications.

In summary, if a guaranteed throughput rate is required for a WAN connection, T-1 is the best option among the technologies listed.
