1. What does a Work Breakdown Structure (WBS) help with? → Breaking down project tasks into smaller components
2. What is the purpose of a 'resource calendar' in a resource-loaded schedule? → To define when each resource is available, including vacations and holidays
3. Why are cloud-based scheduling tools advantageous? → They provide real-time collaboration and accessibility
4. When applying fast-tracking, which type of dependency is most commonly modified? → Discretionary finish-to-start dependencies
5. In schedule risk analysis, what does a 'three-point estimate' consist of? → Optimistic, most likely, and pessimistic duration estimates for an activity
6. What is the relationship between the Authorized Work (AW) and the Performance Measurement Baseline (PMB) in a government EVM system? → AW equals PMB plus management reserve
7. Which quality assurance method is most commonly applied in cost-loaded schedule integration to verify that CST professional standards are being met? → Structured audits, peer reviews, and performance metrics aligned with industry benchmarks
8. What scheduling document is commonly required by public agency contracts to substantiate a contractor's request for a time extension? → A contemporaneous schedule delay analysis using the accepted project schedule
9. What is the primary ethical obligation of a CST professional when a conflict of interest arises during resource loading & leveling activities? → Disclose the conflict to all relevant parties and recuse from the decision if necessary
10. Which of the following is a fundamental principle of cost-loaded schedule integration as it applies to Certified Scheduling Technician? → Systematic evaluation and adherence to established industry standards
11. Which lag type applied to a milestone predecessor relationship would delay a milestone by 2 weeks after its predecessor finishes? → Positive lag of 2 weeks on a Finish-to-Start link
12. Which AACE International Recommended Practice is specifically associated with forensic schedule analysis and delay claim methodologies? → RP 29R-03
13. A schedule network shows that Activity C can start as soon as Activity A is 50% complete. This is modeled as a: → Start-to-start relationship
14. Which of the following is a primary risk associated with fast-tracking? → Increased rework if errors in overlapped activities propagate downstream
15. The 'But For' analysis in schedule delay disputes attempts to answer: → What would the schedule look like but for the alleged delay event?
16. Which quality assurance method is most commonly applied in critical path & float analysis to verify that CST professional standards are being met? → Structured audits, peer reviews, and performance metrics aligned with industry benchmarks
17. Which scheduling concept specifically uses milestones as weighted events to measure physical percent complete in government contracts? → Milestone Weighted Method (MWM)
18. Which Integrated Baseline Review (IBR) objective verifies that the cost-loaded schedule is achievable given available resources? → Validate that the PMB is realistic, executable, and adequately resourced
19. In Microsoft Project, what does the 'Peak' field in a resource usage view represent? → The maximum units allocated to a task in any single time period
20. A project schedule shows a Schedule Performance Index (SPI) of 0.75. This means the project is: → 25% behind schedule — only 75 cents of work done per $1 planned
21. Which document outlines who is responsible for each project task? → Responsibility Assignment Matrix (RAM)
22. In Primavera P6, which earned value calculation method computes BCWP based on the physical percent complete entered by the user? → Physical Percent Complete
23. Which risk response strategy involves adding parallel activities to reduce schedule risk? → Fast-tracking
24. What is a milestone in project scheduling? → A major event or achievement in the project
25. In schedule compression, crashing differs from fast tracking in that crashing: → Adds resources to critical path activities to shorten duration
26. What is a primary benefit of using scheduling software? → Increases scheduling efficiency and accuracy
27. What is the purpose of a project schedule? → To plan and track project activities and deadlines
28. What is the primary ethical obligation of a CST professional when a conflict of interest arises during p6 & ms project proficiency activities? → Disclose the conflict to all relevant parties and recuse from the decision if necessary
29. A project schedule network diagram that shows all activities as nodes connected by arrows representing dependencies is using which method? → Precedence Diagramming Method (PDM)
30. In Monte Carlo simulation for schedule risk analysis, what does the P80 date represent? → The date by which there is an 80% probability of completing the project
