41. A project manager is managing a project that has reached the end of planning phase. The work scope has been agreed to and definitive cost estimates have been completed for the project. The total estimated cost of the project is $100,000. It is reasonable to expect that the project will not cost over which of the following value?
The following information and questions 42 through 51 refer to Figure 1
A schedule was developed for a project to install windows in an apartment building. The project is a rush job, and the contractor has agreed to schedule the work on a single shift basis but will work seven days per week until the job is done. The project is to begin on May 1.
42. What day in May will activity D have for its early finish date?
a. May 13
b. May 6
c. May 7
d. May 5
43. What is the free float for activity F?
44. What is the free float for activity D?
45. What is the critical path of the project?
a. A B E G H
b. A B D F H
c. A C G H
d. A B E D F H
46. What is the late start for activity F?
a. May 10
b. May 11
c. May 12
d. May 14
47. How long is the project in days?
48. What is the early start for activity F?
a. May 7
b. May 6
c. May 5
d. May 4
49. If there is a delay in activity F of six days, what is the effect on the project completion date?
a. Increases one day
b. No change to project completion date
c. Increases two days
d. Increases three days
50. What is the early finish date for activity A?
a. May 1
b. May 2
c. May 3
d. May 4
51. The above diagram is called:
a. Activity on arrow network diagram
b. Network diagram
c. Precedence diagram
d. Gantt chart
52. If a project manager were to make Thanksgiving dinner, two of the activities that might be of concern would be roasting the turkey and baking the sweet potatoes. In order to ensure that these two items will be finished cooking and will come out of the oven at the same time, what type of relationship should he or she use in the schedule between these two activities?
a. Finish – finish
b. Start – start
c. Finish – start
d. Start – finish
Questions 53 through 56 refer to the diagram in Figure 2 and the table that follows.
In a project to install concrete sewer lines there is a lot of uncertainty as to how long the durations should be for the tasks involved. The project manager has determined that the team will use the PERT technique to evaluate the project’s completion date. The diagram shows nine
activities and the table shows the optimistic, pessimistic, and most likely estimates that the team has already made.
53. What is the expected value of the number of days to complete the project?
54. It is desirable to make an estimate that has a greater than 95% chance of being correct. Which of the following ranges of time for the impletion of the project best describes this probability of being correct?
a. 33.31 to 31.36
b. 34.28 to 30.39
c. 14.39 to 33.48
d. 35.25 to 29.42
55. What is the expected value of the duration for activity B?
56. What is the standard deviation for the duration of activity B?
57. The project manager decided to improve the predicted completion date for the project by doing in parallel several of the activities that were scheduled to be done in sequence.
This is called:
b. Increasing priorities
c. Hurry up defense
d. Fast tracking
58. Crashing the schedule means:
a. Making the project shorter by any economic means
b. Running the project team on overtime
c. Doing activities that were in sequence in parallel
d. Getting out of town before the project is in trouble
59. The original schedule (for a project, a work package, or an activity). Plus or minus approved changes, is called:
a. The working schedule
b. The target schedule
c. The performance schedule
d. The baseline schedule
60. Schedules are used in many ways. In a project to build a bridge the project manager wants to use a tool that will show the scheduled activities in such a way that it is easy to see when each activity starts and finishes and which activities are taking place at the same time. Which tool should be used?
a. PERT chart
b. Gantt chart
c. Precedence diagram
d. GERT chart

May 12 ( it is as per 1 start method. 0 start and 1start method only difference is that ES and LS or different by 1 day. In this one start method is more appropriate. You can understand by both figues)
No change to project completion date
Finish – finish
Additional Note: This is option C (32.3) as you will need to find out the critical path for each possibility and then calculate the total number of days to complete the project. Then find out EV by formula (O+P+4M)/6. (O-28, P=38, M=32)
34.28 to 30.39
Additional Note: Find out values of EV,SD and activity variance of each activity on critical path. Sum up acitivity variance and take square root of the same. it is SD for project. To find out range ot time of completion for 95% is 2SD.
