Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 478

Which protocol is responsible for data plane forwarding in a Cisco SD-Access deployment?

Answer options

• A. IS-IS
• B. OSPF
• C. VXLAN
• D. LISP

Correct answer: C

Explanation

VXLAN is the correct answer because it is specifically designed for overlay networking and data plane forwarding in SD-Access. IS-IS and OSPF are routing protocols used for control plane functions, while LISP provides additional capabilities for endpoint identification and location but is not primarily focused on data plane forwarding.
