The statement provides an accurate and standard definition of a Wide Area Network (WAN). A WAN is fundamentally a network that spans a large geographical area, often crossing metropolitan, regional, or national boundaries. Its primary purpose is to provide long-distance connectivity, interconnecting geographically separate networks such as Local Area Networks (LANs), Metropolitan Area Networks (MANs), and by extension, specific large-scale LAN implementations like campus networks and data center networks. The use cases mentioned—interconnecting campus and data center networks—are typical enterprise applications for WAN technologies.

This is a "TRUE OR FALSE" question; therefore, there is no incorrect option to evaluate. The provided statement is factually correct.

1. Huawei HCIA-Datacom V1.0 Training Material. In the module covering fundamental network concepts

a WAN is defined by its large geographical scope and its function of connecting other networks like LANs. The material states

"A WAN provides long-distance communication and covers a wide range of areas

such as a country or a continent... A WAN is mainly used to connect LANs in different regions." (HCIA-Datacom V1.0 Training Material

Chapter 1: Data Communication and Network Basics).

K. W. (2021). Computer Networking: A Top-Down Approach (8th ed.). Pearson. This foundational university textbook defines network types by scale. In Chapter 1

it distinguishes between LANs and WANs

stating

"A wide area network (WAN) [...] typically spans tens or hundreds of kilometers. [...] Enterprises often use WANs to connect their geographically distributed offices." This aligns with the statement's description of connecting LANs/MANs in different areas. (Chapter 1

Section 1.2: The Network Edge).

W. (2014). Data and Computer Communications (10th ed.). Pearson. This academic text provides a clear definition: "A wide area network (WAN) covers a large geographical area. A WAN typically consists of a number of interconnected switching nodes. [...] These nodes and the networks they support (which are typically LANs at subscriber sites) are connected by transmission lines." This confirms the role of a WAN in interconnecting LANs.
