Explanation

Cisco ACI uses VXLAN (Virtual Extensible LAN) as its fabric encapsulation technology. VXLAN encapsulates Layer 2 Ethernet frames within UDP/IP packets using a 24-bit VNID (VXLAN Network Identifier), supporting over 16 million logical segments - far exceeding the 4,094 VLAN limit. This allows ACI to build logical overlay networks (EPGs, tenants, VRFs) completely decoupled from the physical underlay, enabling true infrastructure virtualization. The APIC controller automates VXLAN tunnel provisioning across the leaf-spine fabric. STP (A) is a loop-prevention protocol, IPsec (B) is for encryption and secure tunneling, and NSX (D) is VMware's competing SDN/overlay platform - none are used by Cisco ACI as its native encapsulation.
