This is feasible as long as your expertise is recognised in the organisation or you are in a position of power or your organisation is open to this kind of behaviour (quite often it isn’t the case). A junior asking this kind of questions in the wrong organisation may help fixing the problem at hand, assuming they are taken seriously, but they are likely to hinder their career progress if they repeat this behaviour too often. In many many many organisations looking smart is way more important than being smart.

(I’m not saying it’s a good thing)
