Question 1: In a time-phased budget, the cumulative Planned Value (PV) curve is commonly referred to as what shape?
- Bell curve
- S-curve (Correct answer)
- J-curve
- Exponential curve
Correct answer: S-curve
The cumulative PV baseline typically forms an S-curve, starting slow, accelerating through mid-project, and tapering near completion.
Question 2: What are 'liquidated damages' (LD) in the context of project scheduling?
- A daily bonus paid to the contractor for early completion
- The total cost of all schedule delays on a project
- A predetermined daily amount the contractor must pay the owner for each day the project extends beyond the contract completion date (Correct answer)
- The amount the owner reimburses the contractor for accelerating the schedule
Correct answer: A predetermined daily amount the contractor must pay the owner for each day the project extends beyond the contract completion date
Liquidated damages are a fixed daily monetary penalty specified in the contract that the contractor owes the owner for each calendar day of delay beyond the contract completion date.
Question 3: Which scheduling concept defines the earliest point in time an activity can begin based on its predecessors?
- Late Start (LS)
- Early Start (ES) (Correct answer)
- Planned Start (PS)
- Early Finish (EF)
Correct answer: Early Start (ES)
Early Start (ES) is the earliest possible date an activity can begin, determined by the forward pass through the network.
Question 4: Which scheduling output is considered the PRIMARY tool for communicating the project timeline to stakeholders?
- S-curve
- Network diagram
- Gantt chart (bar chart) (Correct answer)
- Resource histogram
Correct answer: Gantt chart (bar chart)
Gantt charts visually display activities against a calendar timeline and are the most widely used tool for communicating schedules to stakeholders.
Question 5: A Start-to-Start (SS) relationship with a lag of 2 days between Activity A and Activity B means:
- B must start at least 2 days before A starts
- B cannot start until at least 2 days after A starts (Correct answer)
- A and B must start on the same day within 2-day tolerance
- B finishes 2 days after A starts
Correct answer: B cannot start until at least 2 days after A starts
An SS+2 lag requires B's start to be delayed at least 2 days after A begins, allowing partial completion of A before B commences.
Question 6: When a project schedule shows negative float on the critical path, this indicates:
- The project cannot meet its imposed finish date without corrective action (Correct answer)
- Resources are under-allocated
- The network logic has an error that must be corrected
- The project will finish ahead of schedule
Correct answer: The project cannot meet its imposed finish date without corrective action
Negative float means the calculated project finish date exceeds the target finish date, requiring schedule compression or scope/resource changes.
Question 7: In schedule risk analysis, what does a 'three-point estimate' consist of?
- Early start, planned start, and late start dates
- Optimistic, most likely, and pessimistic duration estimates for an activity (Correct answer)
- Best case, base case, and worst case cost estimates
- Minimum, average, and maximum resource units
Correct answer: Optimistic, most likely, and pessimistic duration estimates for an activity
A three-point estimate uses optimistic (O), most likely (M), and pessimistic (P) durations to model activity duration uncertainty for risk analysis.
Question 8: Which process group involves tracking and reviewing project progress?
- Executing.
- Initiating.
- Planning.
- Monitoring and Controlling (Correct answer)

Question 11: A project manager wants to compress the schedule by overlapping phases. Which CPM technique involves starting a successor activity before its predecessor is fully complete?
- Crashing
- Fast-tracking (Correct answer)
- Monte Carlo simulation
- Resource leveling
Correct answer: Fast-tracking
Fast-tracking overlaps activities that would normally be done sequentially, introducing parallel work and potential rework risk.
Question 12: In a delay claim, the concept of 'float ownership' is significant because:
- It is used to calculate the SPI for disputed periods
- It determines which party can consume project float without liability for resulting delays (Correct answer)
- It identifies which activities have the most schedule risk
- It assigns dollar values to each day of float remaining
Correct answer: It determines which party can consume project float without liability for resulting delays
Float ownership determines whether the contractor or owner has the right to use available float; most contracts assign float to the project (not the contractor), meaning owners can use it without owing the contractor time relief.
Question 13: When applying the Critical Path Method, a 'near-critical path' is significant because:
- It has very little float and could become critical if delays occur (Correct answer)
- It has the longest duration in the network
- It identifies activities that should be fast tracked first
- It represents activities with the highest resource requirements
Correct answer: It has very little float and could become critical if delays occur
Near-critical paths have minimal float and pose schedule risk because small delays can make them critical.
Question 14: A resource is assigned to three parallel activities each requiring 4 hours/day. The resource's capacity is 8 hours/day. What is the most appropriate corrective action?
- Replace the resource with two separate resources
- Reduce the work content of all three activities
- Accept the over-allocation and log it as a risk
- Sequence at least one activity to a different time period (Correct answer)
Correct answer: Sequence at least one activity to a different time period
Shifting one activity to a non-overlapping period reduces daily demand from 12 to 8 hours, matching available capacity.
Question 15: If the SPI = 1.15 and the project is 60% complete by schedule, what does this suggest?
- The project will finish 15 days early regardless of remaining work
- The project is 15% over budget
- The project has 15% remaining float
- The project is performing 15% more efficiently than planned and is likely ahead of schedule (Correct answer)
Correct answer: The project is performing 15% more efficiently than planned and is likely ahead of schedule
An SPI of 1.15 means the team is earning $1.15 of planned value for every $1.00 worth of scheduled time, indicating ahead-of-schedule performance.

- In progress with an assumed 0% completion
- Behind schedule and automatically assigned negative float by the scheduling software
- Out-of-sequence if they have predecessors that are not yet complete (Correct answer)
- Complete because the data date has passed their planned start
Correct answer: Out-of-sequence if they have predecessors that are not yet complete
If an activity begins before all its predecessors are finished, it is out-of-sequence, which can create logic conflicts in the schedule.
Question 39: A scheduler is performing 'what-if' analysis by changing activity durations. After increasing Activity M's duration from 5 to 9 days, the project end date does not change. What can be concluded?
- Activity M had at least 4 days of Total Float (Correct answer)
- Activity M is on the critical path
- Activity M had exactly 4 days of Free Float

Correct answer: The Earned Value Management System (EVMS) Compliance Certification
EVMS compliance certification (per ANSI/EIA-748) verifies that the contractor's system meets the 32 guidelines before it can be used for formal government cost reporting.
Question 69: What is a 'Notice to Proceed' (NTP) and how does it affect the project schedule?
- A contractor's formal acceptance of a change order
- An official authorization from the owner allowing the contractor to begin work, which triggers the schedule's start date (Correct answer)
- The date when the first submittal is approved
- A notice issued when procurement is complete
Correct answer: An official authorization from the owner allowing the contractor to begin work, which triggers the schedule's start date
The Notice to Proceed is the owner's official authorization for the contractor to commence work, and it sets the contractual start date from which scheduled durations and completion dates are calculated.
Question 70: Which of the following is a correct statement about total float in a CPM network?
- Total float is shared by all activities on the same path and using it reduces float for other activities on that path (Correct answer)
- Total float can be negative only when the project has no defined end date
- Total float is the exclusive property of a single activity and cannot be shared
- Total float always equals free float for activities on the critical path
Correct answer: Total float is shared by all activities on the same path and using it reduces float for other activities on that path
Total float belongs to the path, not individual activities; consuming float on one activity reduces the available float for others on the same path.

- Budgeted Cost of Work Performed (Correct answer)
Correct answer: Budgeted Cost of Work Performed
BCWP (now called Earned Value) represents the budgeted value of work actually completed, the central metric of EVM performance measurement.
Question 90: In the context of project scheduling, what is a 'hammock activity'?
- An activity that can be performed at any time
- A summary activity that spans between two specified activities in the network (Correct answer)
- A recurring activity that happens throughout the project
- An activity with no predecessors or successors
Correct answer: A summary activity that spans between two specified activities in the network
A hammock activity summarizes a group of related activities and its duration is determined by the start and finish of the activities it spans.
Question 91: What can cause resource overallocation?
- Providing resource availability data.
- Assigning multiple tasks to a single resource beyond capacity (Correct answer)
- Underestimating project timelines.
- Setting strict task priorities.
Correct answer: Assigning multiple tasks to a single resource beyond capacity
Resource overallocation occurs when a resource, such as a team member or piece of equipment, is assigned more work than they can realistically complete within a given timeframe. This typically happens when a single resource is scheduled to work on multiple tasks concurrently, exceeding their available working hours or capacity. It leads to burnout, delays, and decreased quality of work.
Question 92: The process of determining how long each project activity will take, considering resource availability and skill levels, is called:
- Activity duration estimating (Correct answer)
- Activity sequencing
- Schedule development
- Activity resource estimating
Correct answer: Activity duration estimating
Activity duration estimating quantifies the number of work periods needed to complete each schedule activity with estimated resources.
Question 93: What is the significance of the 'critical chain' concept compared to the traditional critical path?
- Critical chain eliminates the use of float entirely
- Critical chain accounts for resource constraints and uses buffers instead of individual activity float (Correct answer)
- Critical chain focuses on the longest path ignoring resource constraints
- Critical chain only applies to construction projects
Correct answer: Critical chain accounts for resource constraints and uses buffers instead of individual activity float
Critical Chain Project Management (CCPM) factors in resource dependencies and replaces individual activity buffers with shared project and feeding buffers.
Question 94: The Estimate to Complete (ETC) assumes all future work will be performed at the budgeted rate. Which formula represents this?
- ETC = AC + BAC
- ETC = EV - AC
- ETC = BAC - EV (Correct answer)
- ETC = (BAC - EV) / CPI
Correct answer: ETC = BAC - EV
ETC = BAC - EV assumes the remaining work will be completed at the originally planned cost efficiency (CPI = 1.0).
Question 95: In Monte Carlo simulation for schedule risk analysis, what does the P80 date represent?
- The date with the highest probability of completion
- The date representing 80% schedule progress
- The date by which there is an 80% probability of completing the project (Correct answer)
- The 80th calendar day of the project
Correct answer: The date by which there is an 80% probability of completing the project
The P80 date is the date at which there is an 80% statistical confidence that the project will be completed, based on simulated schedule outcomes.
Question 96: What is the purpose of a schedule management plan?
- To identify all project risks that could affect the schedule
- To document the actual project schedule with all activity dates
- To establish policies, procedures, and documentation for planning and managing the project schedule (Correct answer)
- To define the work breakdown structure for the project
Correct answer: To establish policies, procedures, and documentation for planning and managing the project schedule
The schedule management plan defines how the schedule will be developed, maintained, and controlled throughout the project.
Question 97: What is the primary purpose of reconciling a cost-loaded schedule with the project's Control Account Plan (CAP)?
- To ensure the schedule matches the master project schedule
- To confirm that the schedule logic has no loops
