The answer is time, cost, and scope. These three elements form the classic triple constraint in the PMBOK Guide, which states that any change to one constraint will inevitably impact at least one of the other two. For the CompTIA Project+ PK0-005 exam, this concept tests your understanding of how project constraints interact to define project success, often appearing in scenario-based questions where you must identify which constraint is most affected by a given change. A common trap is confusing quality or resources as a primary constraint, but PMBOK specifically recognizes scope, time, and cost as the core triple constraint. To remember this, think of the mnemonic "S-T-C" for Scope, Time, Cost—or simply recall that every project must answer "What will we do, how long will it take, and how much will it cost?"
PK0-005 Project Management Concepts Practice Question
This PK0-005 practice question tests your understanding of project management concepts. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which THREE of the following are commonly recognized project constraints according to the Project Management Body of Knowledge (PMBOK)?
Why wrong: Incorrect. Communication is a knowledge area, not a constraint.
C
Scope
Correct. Scope is a fundamental constraint that defines the work to be done.
D
Quality
Why wrong: Incorrect. Quality is often considered a constraint, but in the classic triple constraint it is not always included. However, the question specifies 'commonly recognized' which typically refers to scope, time, and cost.
E
Time
Correct. Time (schedule) is a key constraint affecting project completion.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Cost
Cost is a core project constraint in the PMBOK framework, representing the financial resources required to complete the project. It is part of the classic 'triple constraint' (scope, time, cost) that forms the foundation of project management. Managing cost involves budgeting, monitoring expenditures, and controlling changes to prevent budget overruns.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the distinction between project constraints (scope, time, cost) and knowledge areas (e.g., communication, risk, quality), leading candidates to mistakenly select communication or quality as primary constraints.
Detailed technical explanation
How to think about this question
The PMBOK Guide defines constraints as factors that limit the project management team's options, with the triple constraint (scope, time, cost) being the most fundamental. In practice, these constraints are interdependent: changing scope often affects time and cost, and trade-offs must be managed. Real-world projects use tools like earned value management (EVM) to track cost and schedule performance against the baseline.
KKey Concepts to Remember

Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the PK0-005 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.

Variation 1. Which TWO of the following are commonly considered as project constraints according to the Project Management Body of Knowledge?
medium
A.Communication
B.Quality
C.Resources
✓ D.Scope
✓ E.Budget
Why D: According to the PMBOK Guide, the triple constraint (also known as the iron triangle) traditionally includes scope, time, and cost (budget). Scope defines the work required to deliver the project's deliverables, and any change to scope directly impacts time and cost. Therefore, Scope (D) is a core project constraint.
