Summary
A WAN is defined asA data communications network that operates beyond the geographic scope of a LAN
WAN primarily operate on layer 1 & 2 of the OSI model
WAN technologies include–Leased line
–ISDN
–Frame relay
–X.25
–ATM

Summary Cisco Enterprise Architecture
–This is an expansion of the hierarchical model that further divides the enterprise network into
•Physical areas
•Logical areas
•Functional areas
Selecting the appropriate WAN technology requires considering some of the following:
–WAN’s purpose
–Geographic scope of WAN
–Traffic requirements
–If WAN uses a public or private infrastructure
