Which statement describes a characteristic of a WAN?
- A WAN operates within the same geographic scope of a LAN, but has serial links.
- A WAN provides end-user network connectivity to the campus backbone.
- WAN networks are owned by service providers.
- All serial links are considered WAN connections.
Explanation: WANs are used to interconnect the enterprise LAN to remote branch site LANs and telecommuter sites. A WAN is owned by a service provider. Although WAN connections are typically made through serial interfaces, not all serial links are connected to a WAN. LANs, not WANs, provide end-user network connectivity in an organization.
