A manufacturer has dual transports MPLS and Internet at a hub, both reaching remote Site 10. Engineering wants Internet preferred for bulk replication traffic to that prefix, with MPLS as backup, without changing system-wide defaults for other sites. Which TLOC preference configuration best influences path selection toward that destination?
Select an answer to reveal the explanation.
Short Explanation
You're voting for a favorite road without closing the other. A higher TLOC preference on Site 10's Internet TLOC tells the hub to favor Internet toward that destination first.
Full Explanation
The correct configuration works because TLOC preference is carried in OMP with the advertised prefix and is evaluated by the sender toward that specific destination, so raising it only on the Site 10 Internet TLOC makes the hub prefer Internet for routes to Site 10 while retaining Site 10 MPLS as backup and preserving defaults for all other sites. The centralized default approach fails by scope because modifying the default policy changes path selection overlay-wide rather than scoping influence to the Site 10 prefix, which violates the requirement to leave other sites unchanged even though preferring Internet is otherwise sound. The Site 10 MPLS approach fails by transport selection because it correctly uses destination-scoped preference and correct directionality but inverts the business intent, making deterministic MPLS preferred for bulk replication when the scenario explicitly requires Internet primary with MPLS only as backup. The hub Internet TLOC approach fails by directionality because a TLOC preference advertised by the hub controls how remotes select a path inbound to the hub, not how the hub selects a path outbound to a remote, so it cannot steer hub-to-Site 10 forwarding despite using the desired transport. An exam caveat is to distinguish TLOC preference for destination-specific egress selection from system-level or centralized defaults and from tie-breakers like TLOC carrier, site preference, or data-policy local-preference that operate at different scope. As a practical check, verify on the hub with the OMP table for the Site 10 prefix that the Internet TLOC shows higher preference and is selected as best, then confirm failover by withdrawing that path and observing MPLS becomes active without affecting other site prefixes.
