- Employees need to connect to the corporate email server through a VPN while traveling.
- Employees in the branch office need to share files with the headquarters office that is located in a separate building on the same campus network.
- Employees need to access web pages that are hosted on the corporate web servers in the DMZ within their building.
Which statement describes a characteristic of a WAN?
- A WAN operates within the same geographic scope of a LAN, but has serial links.
- WAN networks are owned by service providers.
