A is right - B would be right if it stated "It allows VXLAN to be applied as a network virtualization overlay though encapsulation". but it doesn't it states "It allows LISP to be applied as a network virtualization overlay though encapsulation.".

Locator ID Separation Protocol (LISP) solves this issue by separating the location and identity of a device through the Routing locator (RLOC) and Endpoint identifier (EID): + Endpoint identifiers (EIDs) – assigned to end hosts. + Routing locators (RLOCs) – assigned to devices (primarily routers) that make up the global routing system.

LISP can be applied as a network virtualization overlay through encapsulation, but Cisco's SD-Access uses VXLAN. Are RLOC and EID two separate entries? Or are they one mapped entry?
