What happens to traffic traversing SD-WAN fabric that doesn’t match any SD-WAN policies?
A . Traffic is dropped because there is no matching SD-WAN policy to direct traffic.
B . Traffic matches a catch-all policy that is created through the SD-WAN plugin.
C . Traffic matches implied policy rules and is redistributed round robin across SD-WAN links.
D . Traffic is forwarded to the first physical interface participating in SD-WAN based on lowest interface number (i.e., Eth1/1 over Eth1/3).

Answer: C

Explanation:

If there is no match to any SD-WAN policy rule in the list, the session matches an implied SD-WAN policy rule at the end of the list that uses the round-robin method to distribute unmatched sessions among all links in one SD-WAN interface, which is based on the route lookup.
