Explanation

VXLAN (Virtual Extensible LAN) is the encapsulation protocol used by VMware NSX to create overlay networks, tunneling Layer 2 frames over a Layer 3 UDP infrastructure - enabling virtual networks to span physical boundaries without changing the underlying network. VRLAN (A) and VMLAN (D) are fabricated distractors that don't correspond to real networking protocols. GRE (C) is a real tunneling protocol, but it's a general-purpose Cisco-associated encapsulation method and is not what NSX uses for its software-defined networking fabric. Memory tip: think VXLAN = eXtensible - NSX extends virtual networks across data centers, and VXLAN is the protocol that makes that extension possible.
