Answers to Exam Prep Questions

  1. Answer C is correct. The first process in the planning group is develop project management plan. Answers A, B, and D skip the first process and start subsequent processes prematurely.

  2. Answer B is correct. The preliminary scope statement is an input you need before starting the scope definition process. Answer A is incorrect because product analysis is a tool and technique of scope definition, not an input. Answer C is incorrect because project management plan updates are an output, not an input. Answer D is incorrect because the WBS is an output of a subsequent process and would not be available at this point. Know your inputs, tools, techniques, and outputs of all processes.

  3. Answer A is correct. A properly sized work package is one that is small enough to allow for reliable estimates for required resources and duration. Answers B, C, and D are incorrect because they assume you are working toward some artificial target that does not contribute to well-sized work packages.

  4. Answer B is correct. Rolling wave planning is providing detailed plans for tasks that are about to start in the near future using the most current information and revisiting future activities when they near their starting dates. Answer A is incorrect because progressive elaboration is the reason many project details might not be known up front, not the practice of providing detailed plans as project activities near their start date. Answers C and D are incorrect because they are not valid project planning terms.

  5. Answer A is correct. The precedence diagramming method (PDM) supports finish-to-start, finish-to-finish, start-to-start, and start-to- finish dependencies. Answer B is incorrect because the arrow diagramming method (ADM) only allows for finish-to-start dependencies. Answers C and D are incorrect because they are both nonexistent diagramming methods.

  6. Answer B is correct. The arrow diagramming method (ADM) is also referred to as activity-on-arrow (AOA) diagramming method. Answer A is incorrect because the precedence diagramming method (ADM) is also referred to as activity-on-node (AON) diagramming method. Answers C and D are incorrect because they are both non-existent diagramming methods.

  7. Answer B is correct. The path A-C-E-G is the longest direct path from start to finish. All other answers are incorrect because they either state the incorrect path or project duration.

  8. Answer A is correct. Because task D is not on the critical path and has a slack of one day, it can start one day late (at most) without affecting the project end date.

  9. Answer C is correct. Because task C is on the critical path, any delay of the task delays the project.

  10. Answer B is correct. Bottom-up estimating is the process of calculating estimates by aggregating the individual estimates of activities that make up the desired activity group. Answer A is incorrect because parametric estimating uses a process of multiplying quantity of work by the productivity rate. Answer C is incorrect because top-down estimating starts with an estimate and decomposes the estimate into smaller units to apply to the individual work packages. Answer D is incorrect because analogous estimating uses similar work packages, not estimate aggregation.
