Question 1 options: o True o False Question 2 (1 point) The network diagram depicts how work packages are sequenced. Question 2 options: o True o False Question 3 (2 points) A network diagram Question 3 options: o Outlines the project’s communication network o Shows how information flows from one project to another o Shows how information flows from one project deliverable to another project deliverable o Displays how project activities are sequenced Question 4 (2 points) Which of the following best shows the time flow and progression of project work? Question 4 options: o WBS o Gantt chart o Network diagram o S-curve Question 5 (1 point) The critical path of a project can be determined using the forward pass algorithm Question 5 options: o True o False Question 6 (2 points) All of the following are techniques which can be used for estimating activity duration and cost except Question 6 options: o 3-point o Parametric o Critical path o Analogous Question 7 (2 points) Which of the following is most useful for visualizing dependency bottlenecks between activities? Question 7 options: o Network diagram o Gantt chart o Critical path o Leads and lags Question 8 (2 points) Which of the following is not true about the critical path? Question 8 options: o It is the path with the largest number of activities o It is a longest (in overall duration) begin-end path in the network diagram o It is a path with the most schedule risk o It is usually the path with the least scheduling flexibility Question 9 (1 point) The project activity with the highest duration must be on a critical path Question 9 options: o True o False Question 10 (2 points) You (as the project manager) are presenting the project schedule to your sponsor and executive team. Which of the following is the best way to present the project’s schedule to them? Question 10 options: o As a single number (example: 21 weeks) o As a range (example: between 19 and 26 weeks) o As a single number and a likelihood (example: 60% likelihood of finishing in 21 weeks) o As a range and a likelihood (example: 95% likelihood of completing within 19 to 26 weeks) Question 11 (2 points) Which of the following is not a possible output of the Estimate Costs process? (Hint: Consult the PMBOK Guide, Sixth Edition, although you should be able to derive the answer from the lectures.) Question 11 options: o Activity cost estimates o Basis of estimates o The project’s cost baseline o Risk register updates Question 12 (2 points) The dependency between activities A and B is a start-to-start: B cannot start until A has started. If the duration of A is 5 days and the duration of B is 7 days, how many days after A starts will A and B both be done? Question 12 options: o 12 o 10 o 2 o 7 Question 13 (1 point) The project activity with the least duration can never be on a critical path Question 13 options: o True o False Question 14 (1 point) The Control Schedule process could update the Lessons Learned Register Question 14 options: o True o False Question 15 (1 point) The schedule baseline can be updated in the Control Schedule process Question 15 options: o True o False Question 16 (1 point) The project schedule is an input into determining the project’s budget/S-curve Question 16 options: o True o False Question 17 (1 point) A Gantt chart depicts activity duration using bubbles – larger bubbles for longer activities. Question 17 options: o True o False Question 18 (1 point) Financing costs (like interest and loan origination fees) are typically not incorporated in project/activity cost estimates Question 18 options: o True o False Question 19 (2 points) What is the duration of the project shown below (numbers are duration in days, and dependencies are all Finish-to-Start AND THERE IS A LAG OF 3 days between D and F, meaning that F can start exactly three days after D finishes). Question 19 options: o 23 days o 25 days o 27 days o 24 days Question 20 (2 points) An agile development team has completed four iterations A, B, C, and D whose durations were 3 weeks, 2 weeks, 4 weeks, and 3 weeks respectively. The story points completed in each iteration were 19, 13, 29, and 23, respectively. Based solely on the team’s velocity (measured in story points per week) roughly how many story points might they be expected to complete in the next 5-week long iteration? (While teams usually plan iterations of equal duration, it is possible to sometimes have slightly unequal duration.) Question 20 options: o 18 o 35 o 45 o 27
