Which three major points are important for network virtualization to separate logical networks on a shared physical infrastructure? (Choose three.)
The correct answer is B. data plane C. control plane F. management plane. Network virtualization relies on separating the three functional planes of a network device: the data plane (B) handles actual packet forwarding and encapsulation/decapsulation of traffic; the control plane (C) manages routing decisions, signaling, and protocol exchanges (e.g…

Explanation
Network virtualization relies on separating the three functional planes of a network device: the data plane (B) handles actual packet forwarding and encapsulation/decapsulation of traffic; the control plane (C) manages routing decisions, signaling, and protocol exchanges (e.g., BGP, OSPF); and the management plane (F) handles device administration, SNMP, SSH, and configuration. Separating these three planes on a shared physical infrastructure is the architectural foundation of network virtualization. VLANs (A), VPNs (D), and VSANs (E) are specific technologies that implement virtualization, not the fundamental architectural planes themselves.
