Bservice
Clocal preference

Explanation

A TLOC, or Transport Locator, is a critical component in Cisco SD-WAN identified by system IP, color, and encapsulation, and can optionally include a 'tag' attribute for policy-based grouping.

Common mistakes.

B. A 'service' is typically an attribute of a service route or a specific type of traffic, not a direct attribute of a TLOC itself, though TLOCs transport services.
C. 'Local preference' is an attribute associated with OMP routes to influence path selection, not a direct attribute of a TLOC; TLOCs have a 'preference' attribute for path selection.
D. Encryption is a security function applied to tunnels formed using TLOCs, but 'encryption' itself is not an attribute of the TLOC, which defines the tunnel endpoint.
