how can frame from host 1 exit on FA0/0? that port is bringing the traffic IN to the router. The traffic going outbound from host 1 via router 1 will take the Fa0/1 route, since that's the outbound port. Look at the picture in reference to the router, the left of the router is inbound and right is outbound (when you are sending data from host 1). Once you look at it from the router's perspective, it should clear your confusion.
