  B.Safety, OSHA and EPA may have placed restrictions on the number of people used on certain activities or in the physical location of the project.

  C.The skill level of the added resources might not be appropriate for the activities to be performe

  D.D.Adding more resources may create additional work and produce inefficiencies (i.

• 4During project execution, the customer authorizes and funds a scope change which requires a major change in the schedule. The baseline schedule:

  A.Now becomes the new schedule, including the changes, and the original baseline is disregarded.

  B.Is still the original baseline but annotated to reflect that a change has taken place.

  C.Is amended to reflect the scope change, but the original baseline is still maintained for post-project review.

  D.B.Is still the original baseline but annotated to reflect that a change has taken plac

  E.C.Is amended to reflect the scope change, but the original baseline is still maintained for post-project review.D.Is meaningless since every schedule update changes the baseline (i.e., a rubber baseline.)E.Is the same since baseline schedules cannot change once the development phase is completed.

• 5Your team has prepared a CPM schedule for your review. You notice that one node has six inputs (including two dummy activities) and four outputs (which include one dummy activity). Select the correct statement from the following:

  A.This is a valid representation if the logic is correct.

  B.This is invalid because a node can have a maximum of one dummy input representation if the logic is correct.

  C.This is invalid because nodes cannot have both dummy inputs and dummy outputs.

  D.This is a invalid because the number of outputs must equal the number of inputs.

  E.This is invalid because a maximum of two inputs and two outputs are allowed using the critical path method.
