2 responses on "PMP Exam Question 130"

  1. PMP® Solution 130.

    X A. Start-to-start (SS) is a logical relationship in which a successor activity cannot start until a predecessor activity has started. For example, level concrete (successor) cannot begin until pour foundation (predecessor) begins. – In this case, there is no reason to prioritize this relationship. –

    X B. Finish-to.finish (FF) is a logical relationship in which a successor activity cannot finish until a predecessor activity has finished. For example, writing a document (predecessor) is required to finish before editing the document (successor) can finish. – In this case, there is no reason to prioritize this relationship. –

    X D. Multiple relationships – (more than 2) – between the same activities are not recommended, so a decision has to be made to select the relationship with the highest impact. Closed loops are also not recommended in logical relationships.

    Two activities can have two logical relationships at the same time (for example, SS and FF). – In this case, both relationships are compatible. since the successor activity can have a start date based on SS and a finish date based on FF, but they don´t necessarily need to.- Therefore, right answer is C.
