Refer to the exhibit. The Cisco ACI fabric forms an OSPF adjacency with R1. The fabric must generate a default route and advertise it to R1 together with all other OSPF routes. Which set of actions accomplishes these objectives?

Explanation

For an OSPF regular area such as area 0, a Cisco ACI Default Route Leak Policy must use the Context scope, which originates a Type 5 external LSA; the Outside scope is for an NSSA and produces a Type 7 LSA. The Leak Default Route in Addition criterion advertises the default route along with other routes, and Always = Yes originates the default route even if it is absent from the routing table.
