No, knowledge of an enterprise service bus is something that is handy. But it is not a prerequisite. If you are not familiar with the concepts that are typically associated with connecting systems, you can always have a discussion with our training department / our trainer, to see if you can attend the training. In some cases, we can give you some reading material. This is to improve your knowledge before the training.  Having said that, we have had project managers, with almost no development experience or knowledge of the concepts of the enterprise service bus, and they were able to complete the training.
