When I interviewed for junior dev roles I answered "I don't know" to questions during multiple job interviews and still got offers after those interviews. Usually after answering that I don't know something I would ask the interviewer how he would handle the proposed problem. My best advice would be if you don't know don't be afraid but have poise and show that you're eager to learn and willing to ask questions.
