Answer: CD

Explanation:

VXLAN (Virtual Extensible LAN) is an overlay technology designed to support large-scale, multi-tenant environments. Unlike traditional VLANs which are limited to 4096 unique network identifiers, VXLANs can support up to 16 million unique network segments, providing significantly greater scalability. This is achieved through a 24-bit VXLAN Network Identifier (VNI). Additionally, being an overlay technology, VXLAN allows for the creation of virtualized Layer 2 networks over an existing

Layer 3 infrastructure.
