Confused on Reflexive ACL

All:

I searched through the archives and did not find what I was looking for. I
looked through the Cisco documentation and found some conflicting
information on the same topic. Here are couple of quick questions:

1. On an exterior interface, is the extended applied in the outbound or
inbound direction? My belief was that if applied in the outbound, that
would create the entry in the nested ACL and allow return traffic back into
the network. Clarify??

2. On an external facing interface, with NAT (outside) configured, will
reflexive ACLs even work?

3. Unsure about the evaluate command. Cisco says the default is not to use
it, but what does it do as opposed to the regular reflexive ACL?

Thanks and regards,

Bob
