An IT associate is working with a video streaming provider. What is a common approach to reduce bandwidth cost while supporting the same or an increasing number of video streams and customers?

Stopping service when a price limit is reached negatively impacts user experience and is not a sustainable business strategy for a video streaming provider.

Reducing the bitrate indiscriminately can significantly degrade video quality, potentially leading to customer dissatisfaction, even if it saves bandwidth.

Limiting the number of users would restrict growth and customer access, directly contradicting the goal of supporting the 'same or an increasing number' of customers.

A CDN distributes content from edge servers geographically closer to users, reducing the load on the origin server and minimizing the long-haul network traffic and associated bandwidth costs. By caching video streams closer to viewers, CDNs improve delivery speed and reliability, enabling support for more streams and customers more efficiently.
