Assuming he has no help of course!
“Ask” a question, probably not.
“Get” a question, why, certainly, it is possible, though I suspect that he deliberatly avoids a lot of questions.
Here’s one for him that he probably wouldn’t get:
“Dear Cecil, can you name every Republican to serve as a Chicago alderman since 1931?”
(Mind you, he lives in that city, so he might still be able to get it.)
Of course not-- don’t be silly!
Cecil is all-knowing, and he has no need to ask questions.

If he would ask: What’s the meaning of life?
No, that would violate the Cecil’s Incompleteness Theorem.
