Question 1
Which of the following is the correct definition of a project according to the Project Management
Institute (PMI)?
A) An ongoing process that produces repetitive results
B) A temporary endeavor undertaken to create a unique product, service, or result
C) A continuous operational activity with no defined end date
D) A routine task performed daily by an organization
Correct Answer: B
Rationale: A project is temporary (definite beginning and end) and creates a unique deliverable.
Operations are ongoing and repetitive.
Question 2
The five process groups in project management according to PMBOK are:
A) Initiation, Planning, Execution, Monitoring & Controlling, Closing
B) Planning, Design, Development, Testing, Deployment
C) Analysis, Design, Implementation, Testing, Maintenance
D) Concept, Development, Production, Operation, Termination
Correct Answer: A
Rationale: PMBOK defines five process groups: Initiating, Planning, Executing, Monitoring &
Controlling, and Closing.
Question 3
Which of the following is NOT a typical constraint in project management?
A) Scope
B) Time
C) Cost
D) Marketing
,Correct Answer: D
Rationale: The classic triple constraint is Scope, Time, and Cost (also called the "iron triangle").
Quality, resources, and risk are also constraints, but marketing is not a project constraint.
Question 4
The project charter serves what primary purpose?
A) To list all project tasks in detail
B) To formally authorize the project and give the project manager authority
C) To create the project schedule
D) To track project costs
Correct Answer: B
Rationale: The project charter is issued by the sponsor and formally authorizes the project,
defines high-level scope, and gives the PM authority to apply resources.
Question 5
Who is typically responsible for approving the project charter?
A) The project manager
B) The project sponsor or initiator outside the project organization
C) The project team
D) The customer
Correct Answer: B
Rationale: The project sponsor (or other external authority) issues and approves the project
charter, providing funding and resources.
Question 6
Which document defines how the project will be executed, monitored, and controlled?
A) Project charter
B) Project management plan
C) Work breakdown structure (WBS)
D) Risk register
Correct Answer: B
Rationale: The project management plan integrates all subsidiary plans (scope, schedule, cost,
quality, etc.) and guides project execution.
,Question 7
The Work Breakdown Structure (WBS) is:
A) A list of project risks
B) A hierarchical decomposition of the total scope of work to be executed by the project team
C) A schedule of project activities
D) A budget spreadsheet
Correct Answer: B
Rationale: The WBS breaks project deliverables into smaller, manageable components (work
packages), forming the basis for scheduling, costing, and assigning responsibilities.
Question 8
The lowest level of the WBS is called a:
A) Task
B) Work package
C) Activity
D) Deliverable
Correct Answer: B
Rationale: The work package is the lowest level of the WBS, representing a deliverable that can
be estimated, scheduled, and assigned to a single person or team.
Question 9
In a WBS, a "100% rule" means that:
A) The project must be 100% complete
B) The WBS includes 100% of the project scope
C) The budget must be 100% accurate
D) The schedule must be 100% on time
Correct Answer: B
Rationale: The 100% rule requires that the WBS captures all deliverables and work required for
project completion, without overlap.
Question 10
What is the purpose of a Responsibility Assignment Matrix (RAM), such as a RACI chart?
A) To assign financial responsibilities
, B) To link project activities to team members and define roles (Responsible, Accountable,
Consulted, Informed)
C) To track project risks
D) To create the project budget
Correct Answer: B
Rationale: A RACI chart clarifies roles: Responsible (does the work), Accountable (approves),
Consulted (provides input), Informed (kept updated).
Question 11
The Critical Path Method (CPM) identifies:
A) The shortest path through the network diagram in terms of duration
B) The longest path through the network diagram, which determines the project's minimum
completion time
C) The most expensive activities
D) The highest-risk activities
Correct Answer: B
Rationale: The critical path is the longest sequence of dependent activities (with zero float) that
determines the earliest project completion date.
Question 12
Float (slack) is defined as:
A) The amount of time an activity can be delayed without delaying the project finish date (total
float)
B) The cost overrun amount
C) The number of resources available
D) The quality variance
Correct Answer: A
Rationale: Float is the amount of time an activity can be delayed without affecting the project
end date (total float) or a successor (free float).
Question 13
An activity on the critical path has:
A) Positive float
B) Zero float (or negative float if delayed)
C) Unlimited float
