An internet service provider (ISP) has a network with multiple users requiring different bandwidth allocations. The ISP needs to multiplex the traffic of 7 users, each with different bandwidth requirements, using Frequency Division Multiplexing (FDM). The bandwidth requirements of the users are as follows: User 1 needs (B+C) Mbps, User 2 needs (C+D) Mbps, User 3 needs (D+E) Mbps, User 4 needs (E+F) Mbps, User 5 needs (F+G) Mbps, User 6 needs (G+H) Mbps, and User 7 needs (H+E) Mbps. To multiplex the traffic efficiently, a guard band of (G+H+B+5) Mbps is required between each user's bandwidth allocation to avoid interference. Illustrate the configuration of the multiplexing and demultiplexing using the frequency domain with proper labeling. Compute the minimum bandwidth requirement as well.

2. A telecommunications company is designing a multiplexing system for transmitting data from six different sources. Each source generates data at varying rates. The bandwidth requirements for multiplexing are as follows: Source 1 requires 6Mbps, Source 2 requires 2Mbps, Source 3 requires 8Mbps, Source 4 requires 6 Mbps, Source 5 requires 11 Mbps, and Source 6 requires 10 Mbps. The multiplexing technique to be used is Statistical Time Division Multiplexing (STDM). Given the requirements above, find: (a) What is data rate management technique that can be used for multiplexing

17. What use case involves providing optimized network paths and bandwidth allocation for different types of traffic, such as voice, video, and data?

Suppose a number of users share a 4 Mbps link. Also, suppose that each user transmits continuously at 2 Mbps when transmitting, but each user transmits only 20% of the time.When circuit switching is used, how many users can be supported? No explanation is required.

16A network administrator is measuring the transfer of bits across the company backbone for a mission critical financial application. The administrator notices that the network throughput appears lower than the bandwidth expected. Which three factors could influence the differences in throughput? (Choose three.)the amount of traffic that is currently crossing the networkthe sophistication of the encapsulation method applied to the datathe type of traffic that is crossing the networkthe latency that is created by the number of network devices that the data is crossingthe bandwidth of the WAN connection to the Internetthe reliability of the gigabit Ethernet infrastructure of the backbone
