An engineer is tasked with designing a dual BGP peering solution with a service provider. The design must meet these conditions:

The routers will make this selection regardless of the service provider configuration.

Which solution should the engineer include in the design?

Use a route map and access list to block the desired networks, and apply the route map to BGP neighbors inbound.

Use a route map and prefix list to block the desired networks, and apply the route map to BGP neighbors outbound.

Use an IP prefix list to block the desired networks and apply the IP prefix list to BGP neighbors outbound.
