Sanitation branch routers must encrypt and forward overlay traffic, but staff confuse planes. Which statement correctly identifies the SD-WAN data plane role?
Select an answer to reveal the explanation.
Short Explanation
Data plane is the garbage truck route—actual payload moving, locked up with encryption. Control plane is dispatch radio. Staff were reading the radio manual when they needed the truck manual.
Full Explanation
Sanitation branch routers that must encrypt and forward overlay traffic use the SD-WAN data plane for that role. The data plane forwards and protects overlay user/site traffic between WAN edges, commonly with IPsec on the overlay path. Staff confusing planes often read management or control documentation when they need the forwarding/encryption path that actually moves garbage-route telemetry and branch application traffic.
Saying the data plane only issues GUI certificates for vManage users and never forwards packets assigns management PKI tasks to the wrong plane. Claiming it computes OSPF areas for the underlay and never encapsulates overlay frames mixes underlay routing design with overlay forwarding. Stating it stores only TACACS accounting records for edge administrators confuses AAA logging with packet forwarding.
Exam caveat: Data plane = forward and protect overlay traffic; do not assign GUI certs, underlay OSPF design, or TACACS accounting as the data-plane definition.
Operational check: confirm IPsec/overlay tunnels are up between sanitation sites, validate encrypted forwarding of user traffic, and keep certificate/management troubleshooting on the management path separate from data-plane drops.
