the analyst uses any model he wants. I hear capm is not the most used model in practice. In exam u will only be given input for one method, or u will be told which method to use. Cfai writes very clear questions

I am not sure what u meen by second part. The items in brackets are equivilant so it depends on what u r given

If u have risk premium you use it as if. If u dont have it, u get it by doin market-rf. If your question is realy just that, i hope u dwel on it and undestand why it is done. It is very simple yet very important
