• 2During 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.

• 3Your 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.

  B.The available slack on the noncritical paths will increase.

  C.A new critical path may appear after the crash.

  D.All of the abov

  E.E.A and B.only.

• 5The critical path in a schedule network is the path that:

  D.Is not affected by schedule slippage

  E.All of the above.

• 6Increasing resources on the critical path activities may not always shorten the length of the project because:

  A.Certain activities are time-dependent rather than resource-dependent (i.e., using three ovens rather than one to bake a cake).

  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.

  E., additional people may need training and supervision.)E.All of the above.

  B.5 weeks

  C.6 weeks

  D.7 weeks

  E.None of the above.

  B.Only those activities with the longest time durations.

  C.Those activities on the critical path begining with the longest time duration activities.

  D.Those activities with the greatest degree of risk.

  E.None of the above.

• 9A network has been developed with resources from six different departments. One of the six departments has just informed you that they can increase the number of employees from 5 to 8. This will result in:

  A.A shortening of the critical path.

  B.A shortening of the noncritical path.

  C.A decrease in the total cost of the project.

  D.An increase in the cost of the project.

  E.A through D are possible based upon where the resources are deployed.
