Which network scenario requires the use of a WAN?
- Employee workstations need to obtain dynamically assigned IP addresses.
- 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.
- Traveling employees must connect to the corporate email server using a VPN.
Explanation: When traveling employees need to connect to a corporate email server through a WAN connection, the VPN creates a secure tunnel between an employee laptop and the corporate network over the WAN connection. Obtaining dynamic IP addresses through DHCP is a function of LAN communication. Sharing files among separate buildings on a corporate campus is accomplished through the LAN infrastructure. A DMZ is a protected network inside the corporate LAN infrastructure.
