If I understand should exist in the Internal and public DNS servers.
So, how does Exchange CAS server know where to redirect the user request (to IP in public or internal DNS) ?

As I wrote in your other question, Exchange doesn't do the DNS lookup at all. It is the client that does it. All Exchange does it tell the client that the mailbox can be located at instead and then it is up to the client browser to find that location.

<<All Exchange does it tell the client that the mailbox can be located at >>

how does Exchange respond to the client ? how does Exchange tell the client "your mailbox can be located at".
The reason I am asking is there are 2 records, one in internal DNS and one in External DNS.

That is correct. You would have two legacy DNS records becaues you need it to work both internally and externally.

Exchange literally says the mailbox isn't here, go here instead.
