A couple jobs ago we had a dedicated "dumb-questions" slack channel that only junior-mid devs were invited to; no managers, so there won't be any fear of judgement. Often the juniors would end up answering each other's questions. Another reason it worked well was that, being a group channel, you didn't have to worry about bothering a specific person who might be busy.
