Hello Rachel,
I am confused why you assumed the answers are completely opposite. I urge you to check my reply again.
for the first question I said " the question clearly stated that the assessment of the CR has been completed. so clearly the next step is to issue the CR and send it for approval." which maps to option A as proposed by the question author.
As for the second question I said "The CR was just raised verbally so the next step is to assess the impact of the CR and then document the CR and send it for approval" this narrows the selection to both B and D as good choices, but remember you always have to choose the best option. my only problem with option B is it referring to project constraints as triple constraints (seems the questions are based on older version of the PMBOK as in newer version there are six competing project constraints Scope,Quality, Schedule, Budget, Resources, and Risks) so this leaves us with option D as the best (I would have chosen B if it didn't specify triple constraints)
It would be great if we can have different point of views and opinions from other members, what would you chose as a correct answer ?
