RED1 is correct:
Loose Mode:
supports using the default route as a route reference
requires the source address to be routable
Strict Mode:
permits only packets that are received on the same interface as the exit interface for destination address
able to drop legitimate traffic
see Question 30
They have given the good answer
I dont agree:
Loose mode: just require the presence of source address in the route table, it can also permit the default route if asked to it. So it support the default route as a route reference.
Strict mode: the packet must be received on the interface that the router would use to forward the return packet.
It can drop a legitimate packet,
