A community college asks what carries user traffic in the SD-Access fabric data plane at principle depth?
Select an answer to reveal the explanation.
Short Explanation
Data plane is the tunnels that actually haul student traffic across the fabric—VXLAN-style overlays between nodes. The management brain writes the plan; the overlay trucks do the hauling.
Full Explanation
A community college asking what carries user traffic in the SD-Access fabric data plane at principle depth should answer overlay encapsulation on the fabric data plane—VXLAN-based fabric forwarding concepts—between fabric nodes. The data plane is where student and staff frames are encapsulated and forwarded across the fabric underlay; management systems orchestrate and the control plane maps identity to location, but user traffic rides the overlay encapsulation between nodes.
Only CLI transcripts stored on the DNA Center appliance with no encapsulation on the wire confuses management logging with forwarding. Untagged access ports that permanently bypass all fabric edges for every subnet abandon the fabric data plane. SMTP relays that serialize each frame into email between buildings are absurd distractors unrelated to fabric forwarding.
Exam caveat: SD-Access data plane = VXLAN-style overlay forwarding between fabric nodes; management appliances do not replace on-the-wire encapsulation.
Operational check: capture or show fabric encapsulation between edge/border nodes for a test client, confirm underlay IP reachability supports the overlay, and keep DNA Center/management troubleshooting separate from data-plane path validation on the community college campus.
