I can answer both questions with "it depends on the scenario".
Each PMP Exam question has to be viewed separately. One question will be this way and another question will be that way. It depends 100% on how the question was developed and framed.
My recommendation is always the same: Don't worry too much about how a question could be asked or not asked. The PMP exam doesn't try to "trick" you. It tests your understanding of general PM concepts.
That much said: Each question on the exam will have the correct amount of information needed for you to find the correct answer.
Until Next Time,
