The project manager for a project is going to use the PERT method of scheduling for the project that she is working on. using PERT calculation the variance fr the project is found to be 25 days. What is the range of values for the project duration such that here will be a least 95% probability that the actual project completion will fall between the high and low value of range of values:

A. 164 - 173 days
B. 144 - 194 days
C. 119 - 219 days
D. 159 - 179 days

answer => D

You just created the following network logic diagram to describe the planned flow of activities for your project which will start tomorrow:

diagram

A. Activity E is a logical dangle in relation to the sink before the finish milestone.
B. Activity F is a logical dangle in relation to the burst point after the start milestone.
C. You can not calculate a critical path when lags and/or leads are calculated in percent.
D. Activities E to F need another task drawn as a hammock to calculate Level Of Effort.

answer => A

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 Time Management 247 table shows the optimistic, pessimistic, and most likely estimates that the team has already made.

What is the expected value of the number of days to complete the Project?
A. 47.3
B. 22.0
C. 32.3
D. 48

answer => C

Use the following information and assumptions for questions bellow:

  • Ÿ A PDM network
  • Ÿ Duration = finish date minus start date + 1
  • Ÿ For a simple FS relationship, the start date of the successor will be one day after the finish date of the predecessor.

-
Activity B Early Start is Day 1; Early Finish is Day 3.
Late Start is Day 6; Late Finish is Day 8.

Activity B has a FS relationship with succeeding Activity C. Activity B has no other immediate succeeding activities. Activity C has an Early Start of 6 days and a Late Start f 11 days.

What is the float or total float for Activity B? (use PMBOK Guide definition of “float” as defined above.)
A. 2 days
B. 5 days
C. 7 days
D. 0 days

answer => B

What is the free float for Activity B? (use definition of “free float” as defined in PMBOK guide above.)
A. 2 days
B. 5 days
C. 7 days
D. 0 days

answer => A
