Question 75.

You have just created the following network logic diagram to describe the planned flow of activities for your project which will start tomorrow:

Which potential inconsistency in the diagram should you solve right now to ensure that the activities and the milestones "Start" and "A-F finished" are correctly linked?

A. Activity E is open ended (a "dangle") in relation to the finish milestone path convergence.

B. Activity F is open ended in relation to the path divergence after the start milestone.

C. You cannot calculate a critical path when lags and/or leads are calculated in percent.

D. Activities E to F need another task drawn as a hammock to calculate level of effort.

yes relationship can be in % which means based on x% of predecessor the successor can start/finish depending on type of relationship
you cannot calculate critical path when relationship are in % and not absolute duration (e.g. days)

oliver mentions that Activity E is dangling activity which is also true and also option C is true
I am also not sure why option C was ruled out.
Activity F can start when activity E is 60% complete then no one really has dependency on when activity E will complete
A dangle activity is a "loose" activity in SND, and it has neither a predecessor activity neither a successor activity.
