Is the CCSP vendor-neutral? I am using various sources with practice test questions and I keep seeing questions about VMWare, Microsoft, etc.
Yes, it's
I believe the development team attempt to keep the certs as vendor neutral as possible.
Just to add.
I took CCSP in 2018, I cannot disclose the content but at least the question asked during the exam, I believe the exam is a vendor neutral.
Also I just visit the exam outline and they are also pretty neutral.

I don't know your various source of "question" is coming from. I have not used the CSSP study app and flash card but you may also download the Official CCSP Study App and Official CCSP Flash Cards and check it out.
