Question

What is the function of the OMP TLOCs in a Cisco SD-WAN network?

Options

Arepresents services in the data center
Bidentifiers that map an OMP route to a physical site
Ccarries OMP service route information
DQoS tags that are used to prioritize traffic

Explanation

OMP TLOCs in a Cisco SD-WAN network are identifiers that map an OMP route to a physical site and its transport location.

Common mistakes.

A. OMP TLOCs represent the transport endpoints of WAN Edge routers, not services in a data center.
C. OMP carries OMP service route information, but the TLOCs themselves are not carrying that information; rather, TLOCs are referenced by OMP routes to indicate the next hop.
D. QoS tags are used to prioritize traffic based on class of service, which is a data plane function, whereas TLOCs are control plane identifiers for routing and reachability.
