Correct Answer
An overlay protocol encapsulating Layer 2 frames in UDP/IP packets, extending Layer 2 networks across Layer 3 boundaries for data center virtualization
Explanation
VXLAN (RFC 7348) encapsulates Ethernet frames in UDP (port 4789) with a 24-bit VNI (16M virtual networks vs VLAN's 4096). Used by VMware NSX, Open vSwitch, and cloud providers for tenant isolation.
