It's wrong to think of an exchange as having "contents". An exchange
really just names a collection of routing rules (i.e. bindings). At no
point is a message ever held "in" an exchange.

But otherwise, yes, exchanges just exist on every node, but the bindings
of that exchange will vary dynamically with the actions of clients and
the failure or restoration of nodes within the cluster.
