It could be considered as a plagiarism depending on the kind of question the question is,there are

some generic questions that might not be

considered as plagarism,but remember i used the word “might”meaning i am not sure,but to be on

the safe side what you should do is that you should first of all ensure you search the question

on musing.io to know if the question is already available ,if it is not available then you can now go

ahead to ask the question but if it is available then you have to stop asking the question
