What is the primary purpose of WAN technologies?

• A. To connect devices within a single local building
• B. To connect multiple LANs across large geographic areas
• C. To replace the Internet
• D. To increase hardware costs

Answer: (B)

WAN technologies are meant to connect networks over long distances, letting separate local networks work together as part of a larger, wide-area network. That explains why the right choice focuses on linking several LANs across large geographic areas. Connecting devices within a single building describes a LAN, not a WAN. Replacing the Internet isn’t what WANs do—the Internet itself relies on wide-area networking to connect networks globally. And increasing hardware costs isn’t the goal of WANs; the purpose is to enable long-distance connectivity so resources can be shared across locations. For example, a company with offices in different cities uses a WAN to connect its branch LANs so everyone can access the same services and data.
