A water utility wants audit-sensitive spoke-to-spoke flows forced through a hub while camera streams may use direct tunnels. Which SD-WAN capability expresses those different topology intents?
Select an answer to reveal the explanation.
Short Explanation
Topology policy lets you be choosy: some water-works traffic must punch the time clock at the hub, while cameras can take the direct tunnel shortcut. One-size full mesh for every VPN ignores audit needs. PortFast at the plant switch does not shape overlay spoke-to-spoke rules.
Full Explanation
Cisco SD-WAN centralized topology policies control whether sites form full mesh, hub-and-spoke, or custom connectivity per VPN or traffic class. Utilities often hairpin regulated flows through hubs for inspection or logging while allowing high-bandwidth camera traffic more direct paths. PortFast is a LAN edge STP feature and does not define overlay topology. Permanently collapsing to a single TLOC reduces resilience rather than encoding nuanced topology intent.
