As far as I'm aware, only through BGP. If you have access to a core cisco router, you can do something like
sh ip bgp 1.2.3.4
and see the multiple routes for an address (if they have some).

No they shouldn't both be allowed. There isn't a way to dynamically choose the route based on whether one or the other connection is up. Packets sent to the down route are simply lost.
