Given two VRFs (Red and Blue) and a next-hop 10.1.1.1 reachable in both VRFs, which static route configuration ensures connectivity for both VRFs?

The correct option uses the ip route vrf command followed by the VRF name, the destination network (0.0.0.0), the subnet mask (0.0.0.0 for a default route), and the next-hop IP address (10.1.1.1). This configuration explicitly creates a default static route within each specified VRF (Red and Blue), directing all traffic for those VRFs to the common next-hop 10.1.1.1. Each VRF requires its own route definition. The incorrect options either use an incorrect subnet mask (255.255.255.255 is not a valid mask for a default route) or only configure the route for a single VRF, which would not provide connectivity for both.
