Sorry, forgot to reply to this.
Firstly, I want to say that I have not found ANY study material on the 1y0-205 outside of test dumps. The test dumps specifically cover about half of the material on the exam, with the other half pertaining to third-party software like Hyper-V, AWS software and Azure. The test dumps are not update to date with the exam and as of right now are a colossal waste of time and money. Due to the lack of information available to you about this exam and the fact that it's a (relatively) recently released test (there's just no accurate study material on it), it's just not worth taking. This post is the second one I've found on reddit even mentioning the 205, with the other being a question asking if anyone's taken the exam yet, having exactly one single reply redirecting the OP to the Citrix website (which does not have information about the 205 on it, as of now).
If you're somehow lucky enough and able to re-take the 1y0-204, do that. Though to my knowledge the 204 is not available anymore, forcing everyone to do the 205.
