Explanation

WAN connectivity methods are technologies used to connect geographically separated networks over a service provider's infrastructure. PPP (Point-to-Point Protocol) is a standard Layer 2 WAN encapsulation protocol used over serial links, dial-up, and DSL. DSL (Digital Subscriber Line) is a common WAN access technology delivered over telephone lines. WLAN is a wireless local area network technology, not a WAN method. L2TPv3 is a tunneling protocol that runs over an existing WAN link rather than being a WAN connectivity method itself. Ethernet is a LAN technology (though Metro Ethernet exists, plain 'Ethernet' in this context refers to LAN).
