A municipal hospital campus is bringing up SD-Access and wants a safe build order. Which sequencing best matches common fabric deployment practice?
Select an answer to reveal the explanation.
Short Explanation
You do not hang patient monitors before the walls and wiring exist. Stand up the underlay roads, then the LISP phone books (control plane), then doors to the outside (borders), then access edges, and only then walk hosts onboard. That order keeps the hospital fabric from collapsing mid-build.
Full Explanation
A typical SD-Access bring-up sequence establishes underlay IP/IGP reachability first, then control-plane mapping services, then border external connectivity, then edge nodes, and finally host onboarding and policy. Skipping ahead to production hosts or wireless without underlay and CP foundations creates unstable overlays and difficult rollback. Sequencing reduces cutover risk on sensitive campuses such as hospitals.
