City change policy requires pre/post health checks covering routes, tunnels, and VTEPs. What does that policy treat as fabric 'monitoring' for validation?
Select an answer to reveal the explanation.
Short Explanation
Pre/post checks are the before-and-after photos of the fabric's vital signs—routes, tunnels, VTEPs—not selfies of the chassis logo. If those vitals match the expected baseline after the window, the change landed; if not, you roll back with evidence. Coffee machines do not count as VTEP health.
Full Explanation
Fabric change validation at the describe level means collecting a deliberate health-check set: routing tables or session state, tunnel/VTEP reachability, and related overlay indicators before and after the window. Cosmetic checks, unrelated facility amenities, or ticket-number rituals do not constitute operational fabric monitoring for change control.
