A public health clinic network maps each underlay attachment for policy matching. What construct identifies those transport attachments in Cisco SD-WAN policy?
Select an answer to reveal the explanation.
Short Explanation
Each WAN plug gets a color name—biz-internet, mpls, lte—like labeled doors on the clinic Edge. Policy matches those TLOC colors when it picks paths. Serial numbers and OSPF process IDs don’t play that matching role.
Full Explanation
A TLOC represents a transport location on an Edge, and its color labels a particular underlay attachment for control-plane advertisement and policy matching. Public-health clinic designs assign colors such as mpls, biz-internet, or lte so Application-Aware Routing, control policy, and data policy can match the correct transport when steering or restricting paths. Without stable color identity, path policy has nothing reliable to match against when underlays change.
The OSPF process ID of the LAN VRF alone does not identify WAN transport attachments for SD-WAN policy matching. Chassis serial without regard to WAN interfaces does not label per-transport TLOCs used in overlays. The vManage cluster name is an operations construct, not the per-attachment match key for underlay colors on an Edge.
Exam caveat: color is the policy-facing name of the transport attachment; do not confuse it with LAN routing process IDs, inventory serials, or controller cluster names when reading exam scenarios.
Operational check: list TLOCs and colors on the clinic Edge, confirm each WAN handoff has the intended color, verify centralized policy matches those colors, and test a color-down scenario to prove steering behaves as designed for clinic traffic.
