As I take quizzes in the 2021 simulator I've come across questions where the answer was "give up" and notify the stakeholder that the objective was unattainable. Then there was one that the answer was terminate project (saying that was the best choice but had the choice to notify the stakeholder, then notify stakeholder would be the preferred choice since PMs can't terminate a project without approval. But how will I know when it comes to answering a question on the exam? In the example above, I knew PMs can't terminate so I didn't pick that and my answer was wrong and that the correct answer was Terminate project. Another example is where there is no way an objective cannot be met, then terminate project. Whereas if the schedule was unattainable, then the answer was submit C/R to modify schedule baseline. If approved, go forward. If denied, then may inform stakeholder that it is unattainable and stakeholder would have to decide to terminate project.
Please advise
