Which network virtualization architecture component transports traffic over isolated Layer 3 partitions?
- path isolation
- access control
- virtual machine
- services edge
Explanation: The network virtualization architecture consists of three main components: access control, path isolation, and services edge. Path isolation is the specific component that functions as an overlay network to create independent logical traffic paths, effectively isolating traffic between different groups over a shared physical infrastructure. This is achieved by maintaining isolated Layer 3 partitions using technologies such as Virtual Routing and Forwarding (VRF), GRE tunnels, or MPLS VPNs to provide end-to-end connectivity while keeping user groups separate.
