A WAN is a network that covers a large geographical area. The Internet is an example of a WAN. A private WAN can be built for a specific organization to link offices across the country or globally. These types of WANs are constructed using dedicated leased lines, satellites, and$/$or microwave communications.

Typically, the LAN$-$to$-$WAN domain addresses many of the WAN connectivity standards. As a result, this domain$$s standards tend to focus primarily on the WAN build$-$out and supporting components. Some organizations may not have any WAN$-$specific standards or policies.

Activity: Provide your commentary $($thoughts$)$ regarding the above statement in terms of an organization not having any specific WAN standards$/$policies in lieu of relying on such needs only in the LAN$-$WAN domain. Is relying on the LAN$-$WAN domain in terms of connectivity standards adequate enough? What about the ISP who provides WAN domain services, should an organization adopt the providers standards as their own?
