Question

Which network virtualization plane is used to separate traffic forwarding tables?

Options

Acontrol
Bdata
Cmanagement
Daccess

Explanation

In network virtualization architecture, the three planes are: the control plane (routing protocols, signaling, table-building), the data plane (also called the forwarding plane-actual packet forwarding using FIB/CEF tables), and the management plane (device configuration and monitoring). Separating traffic forwarding tables-such as creating per-VRF FIBs so that packets from different logical networks are forwarded independently-occurs in the data plane. The control plane builds the routing tables that feed those forwarding tables, but the act of maintaining and using separate forwarding tables for isolated traffic belongs to the data plane. The management plane and 'access plane' have no role in forwarding table separation.
