Question 1
What is the BEST evidence that a project's schedule configuration management is functioning effectively?
- The schedule has been re-baselined four times this year
- Every change is traceable from request to implementation
- The team uses the most expensive scheduling software
- The project manager personally approves each schedule edit
Show answer & explanation
Correct answer: B - Every change is traceable from request to implementation
Question 2
An activity has a PERT expected duration of 10 days and a standard deviation (σ) of 2 days. There is approximately a 95% probability the activity will finish within:
- 8 to 12 days (one standard deviation either side of the mean)
- 10 to 12 days (only adding one standard deviation to the mean)
- 4 to 16 days (three standard deviations either side of the mean)
- 6 to 14 days (two standard deviations either side of the mean)
Show answer & explanation
Correct answer: D - 6 to 14 days (two standard deviations either side of the mean)
Question 3
An activity has Total Float = 5 days and Free Float = 2 days. Delaying its start by 4 days will:
- Result in negative float, requiring crashing or fast-tracking to recover the schedule
- Use 4 days of total float only, with no delay to any of the successor activities
- Use 4 days of free float, with no impact whatsoever on the project's end date
- Use 2 days of free float and 2 days of total float, delaying at least one successor
Show answer & explanation
Correct answer: D - Use 2 days of free float and 2 days of total float, delaying at least one successor
Question 4
When a hard date constraint forces an activity to start earlier than the network logic permits, the scheduler will typically observe:
- Artificial positive float on the constrained activity that masks the actual risk
- Negative float that the schedule cannot mathematically resolve cleanly
- Doubled durations on the constrained activity within the project schedule
- Automatic deletion of the constrained activity by the scheduling tool
Show answer & explanation
Correct answer: B - Negative float that the schedule cannot mathematically resolve cleanly
Question 5
A project reports BAC = $100,000, EV = $40,000, AC = $50,000, and PV = $45,000 at the data date. The project is:
- On schedule (EV = PV) and exactly on budget (AC equals EV) right now
- Ahead of schedule (EV > PV) and under budget (AC < EV) at the data date
- Behind schedule (EV < PV) and over budget (AC > EV) at the data date
- Insufficient information given to determine schedule and cost status today
Show answer & explanation
Correct answer: C - Behind schedule (EV < PV) and over budget (AC > EV) at the data date
Question 6
The SPI convergence problem is the PRIMARY motivation for which scheduling technique?
- Critical Chain Method, which uses buffers instead of activity reserves
- Earned Schedule, which expresses schedule performance in time units
- Monte Carlo simulation, which models thousands of network iterations
- DCMA 14-Point assessment, which evaluates schedule quality metrics
Show answer & explanation
Correct answer: B - Earned Schedule, which expresses schedule performance in time units
Question 7
A project has Planned Duration = 100, Earned Schedule = 60, and Actual Time = 70 at the data date. TSPI(t) - the To-Complete Schedule Performance Index in time - is approximately:
- (70 − 60) / 100 = 0.10 - interpreted as a simple variance ratio at the data date
- (100 − 70) / (100 − 60) = 30 / 40 = 0.75 - indicating future ease at hand
- (60 − 70) / 100 = −0.10 - interpreted as a negative variance ratio at date
- (100 − 60) / (100 − 70) = 40 / 30 = 1.33 - indicating future challenge
Show answer & explanation
Correct answer: D - (100 − 60) / (100 − 70) = 40 / 30 = 1.33 - indicating future challenge
Question 8
Project A has 1 critical path. Project B has 1 critical path plus 7 near-critical paths (all within 3 days of the critical path). Project B is:
- Less risky because more paths offer redundancy in network execution
- More fragile because more paths can become critical with small slippage
- Identical in risk profile because both have one true critical path each
- Unable to be analyzed by CPM since multiple near-critical paths invalidate
Show answer & explanation
Correct answer: B - More fragile because more paths can become critical with small slippage
Question 9
When performance evaluation at closeout reveals significant unfavorable schedule variance, the project team should:
- Document root causes thoroughly to support lessons learned and OPA updates
- Hide the variance from stakeholders to maintain confidence in the team
- Re-baseline retrospectively to make the variance disappear from records
- Cancel the closeout process and continue execution despite the project end
Show answer & explanation
Correct answer: A - Document root causes thoroughly to support lessons learned and OPA updates
Question 10
Honest communication of unfavorable schedule news to stakeholders is:
- Required only when the project sponsor requests a formal compliance review
- Optional based on the project manager's discretion and stakeholder relationships
- Required only when the customer's external auditor requests a written review
- Required by the PMI Code of Ethics regardless of how unwelcome the news is
Show answer & explanation
Correct answer: D - Required by the PMI Code of Ethics regardless of how unwelcome the news is
