Options

ATLOC routes
BvRoutes
Cmulticast routes
Dservice routes

Explanation

This question asks for the specific term used in Cisco SD-WAN to describe routes learned from a local site via a WAN Edge router.

Common mistakes.

A. TLOC routes (Transport Locator routes) represent the WAN Edge router's public-side interface IP address, transport color, and encapsulation, not the prefixes behind the local site.
C. Multicast routes are specifically for multicast traffic and are a subset, not the general term for all local site prefixes.
D. Service routes is a broader term that sometimes encompasses vRoutes, but vRoutes is the more precise and commonly used term in Cisco SD-WAN for routes learned from local services and advertised into the overlay.

Concept tested. SD-WAN route types - vRoutes
