Question 2:
So let's begin. First, your statement supporting answer A is simply the wrong approach to the PMP exam. You have gone into the question with an assumption (or an agenda) on how YOU think things should be done. This is not how you approach PMP exam question. The point of all PMP exam questions is to pick the BEST (or least worst from those given). Let's start by eliminating two answers. Both B and C can be eliminated as nonsensical. First, "apply critical path method" is a scheduling technique not found in the current process and "options for recommended corrective action" is vague and vacuous.
Thus, we are left with A and D. The problem with D is "using the internet as a tool". The "internet" is not a tool per se and is vacuous. A Monte Carlo simulation is a computer program run iteratively which produces a range of possibilities. Secondly, the question is "how can we include the experts"? Obviously, this answer is not how you would design a Monte Carlo simulation and secondly, it does not help the experts communicate their ideas.
Thus, we are left with D. PMBOK, pg. 432 shows that facilitation is a tool and technique that can "can improve effectiveness by establishing a clear understanding of the purpose of the workshop, building consensus among participants, ensuring continued focus on the task, and using creative approaches to deal with interpersonal conflict or sources of bias.".
Again, this is a great PMP question because we have to make sure our answer fully answers the question. Facilitation is a tool and technique used in Perform Quantitative Risk Analysis, fully answers the question.
D, final answer.
