You can't create 'a consumer for an exchange'.

Except from that, that's pretty common question. It all depends on your
design. Often you can have a single queue with one consumer
and a whole bunch of exchanges and bindings. The other time
it might be better to have a single exchange and many queues.

That's the whole point of AMQP, you can create topology as you need it.
So start with something simple, that you feel comfortable with.

Yes, a queue can have multiple bindings.

BTW, have you seen our tutorials?
