Study Hall Questions Wrong

Cristina, I do agree that B is a better answer given no other information is mentioned.

That said, if the radiology team at the hospital is directly involved in site readiness, equipment installation coordination, training schedules, and clinical acceptance, they might control critical path activities that influence the overall timeline which would make A as the most correct answer but nothing of this sort is mentioned in the stem.

I heard from lots of candidates about the confusion that PM Study Hall questions are creating. I personally like PM PrepCast simulator because it provides rationale for all answers and this is where you learn most. 

Cristina, in this case, I would say that D is the most correct answer. Here’s my rationale:

We’re entering a high-activity phase, which means communication needs will likely increase and possibly change in format, frequency, and urgency. Before jumping into tactics like sending updates, choosing tools, or scheduling training, the project manager should start by revisiting the communications management plan.

This plan serves as the foundation for how, when, and with whom communication happens. If the increased demands of this new phase weren’t fully anticipated during planning, then formally updating the plan is the right first step to ensure alignment and consistency across all stakeholder groups.

That said, I do think the question is missing a bit of context that would help make the decision clearer but based on what’s given, D is the most appropriate choice.

Hope this helps!
