What is a benefit of using VXLANs in a cloud-scale environment?

The correct answer is A. extends Layer 2 segments across the underlying Layer 3 infrastructure. This is the core benefit of VXLAN in cloud-scale designs. VXLAN encapsulates Layer 2 frames into IP/UDP headers, allowing isolated Layer 2 segments (per VNI) to be stretched across a routed IP network. This enables: Multi-tenant Layer 2 connectivity across a distributed cloud…

Explanation

This is the core benefit of VXLAN in cloud-scale designs. VXLAN encapsulates Layer 2 frames into IP/UDP headers, allowing isolated Layer 2 segments (per VNI) to be stretched across a routed IP network. This enables: Multi-tenant Layer 2 connectivity across a distributed cloud fabric Mobility of virtual machines or containers while keeping same IP/MAC addressing Use of an IP-based leaf璼pine or service provider underlay for scalability and resiliency
