A tax assessor needs to add a new closet switch to an existing SD-Access fabric without rebuilding the campus underlay from scratch. What approach aligns with incremental fabric expansion?
Select an answer to reveal the explanation.
Short Explanation
Adding a closet should feel like plugging in another desk phone on a working PBX—not ripping out the whole phone system. Discover it, give it underlay IP reachability, then let the controller provision the edge role. Greenfield rebuilds are the wrong reflex for one new switch.
Full Explanation
SD-Access supports incremental addition of fabric devices: inventory the switch, integrate it into the underlay with correct addressing and routing, then assign fabric roles and provision overlay features through the controller. Rebuilding all VNs or converting to unrelated architectures is unnecessary for a single closet expansion. The critical dependencies remain underlay reachability and successful controller management of the new node.
