When searching on Google, I found that it's a lot more common to use is than are in phrases such as "What is/are your name and date of birth?".
Why is that? To me, it feels more natural to use is in the sentence; however, seeing as we're asking about both name and date of birth (i.e., two things) I wonder why the plural form (are) isn't used.
What's grammatically correct in the following sentences, and why?
What is vs. what are your name and height?
What is vs. what are your favorite possession and dream car?
Thanks.
Perhaps you could be so kind as to direct me to the questions you're referring to?

No-one ever asks for anything like name and height, nor possession and dream car but if they forced themselves to ask unnatural questions in order to prove a point, they should use are.
