Honestly, for an interested one but with no experience, they can answer these questions with confidence.

But the question is, will they able to bring that confidence once they are now in actual trade?

The real game and challenge will be on the actual trade so those questions are not really a basic question if they are ready or not. Learn basic, be serious and start. The only one survives are those who will able to withstand the effect, stress, and pressure of doing day trades.
