Which of the following is a benefit of using a WAN?

Using a Wide Area Network (WAN) provides significant benefits, particularly when it comes to cost-effective data sharing over long distances. This capability allows businesses and organizations to connect multiple locations that are geographically dispersed, facilitating communication and data exchange without prohibitive costs. WANs enable users to share resources, including applications and files, across vast distances, which is essential for companies operating in multiple regions or countries.

The cost-effectiveness arises from the ability to use shared communications infrastructure (like the Internet) rather than relying on expensive private lines. This makes it feasible for organizations to maintain communications and operational efficiency across their branches or remote sites without incurring substantial expenses associated with traditional long-distance communication methods. Overall, the capability to optimize data transfer and enhance accessibility over extensive areas underscores the strength of WANs in modern networking.
