An organization currently has 10 employees. The network has a 3 Mbps WAN link. For most of the working day, the WAN link has a utilization of 2.5 Mbps. Occasionally, this peaks to 3Mbps; when this occurs, WAN packet loss increases from 0% to 5%.

Predict the bandwidth of the WAN link that will be required when the organization expands to 25 employees. Give sound reasoning to justify your prediction.
