Which Cisco SD-WAN transport location type commonly represents MPLS, broadband internet, or LTE WAN connectivity?

• A. TLOC
• B. VRF
• C. VNI
• D. SGT

Answer: (A)

In Cisco SD-WAN, the element that maps to the underlying WAN connections is the Transport Locator, or TLOC. Each edge can have multiple TLOCs, with each one representing a different transport path such as MPLS, broadband Internet, or LTE. These TLOCs advertise reachability and are used by the overlay to perform dynamic path selection and fast failover, letting traffic ride the best available link based on policies and performance metrics. VRF pertains to separate routing tables, not the transport type. VNI is the overlay network identifier for traffic segmentation, and SGT is a security tag for policy application. Therefore, the transport location type that commonly represents MPLS, broadband Internet, or LTE WAN connectivity is the Transport Locator.
