Is the RabbitMQ RPC a kind of "Work queue" with response?

is the RabbitMQ RPC a kind of Work queue with response? In the RPC description you can read:

If the RPC server is too slow, you can scale up by just running another one. Try running a second rpc_server.py in a new console.

So in my mind RPC is a worker queue and every worker is responding if task is done. Or am I wrong?

Thanks in advance.
