The specification does not define any defaults, but your client library
may. "no-ack" and "auto-ack" are synonyms, so their defaults will be the
same.

No. You may be confusing any combination of basic.return, publishing
with the mandatory flag and publisher confirms. I suggest you read the
text of the tutorials which introduces messaging concepts:
