The correct answer is R003 because its risk score of 0.72 is the highest, calculated by multiplying its probability of 0.8 by its impact of 0.9. In project risk management, the risk score is determined by the formula probability × impact, and R003’s product exceeds those of R001 (0.35) and R002 (0.48). On the CompTIA Project+ PK0-005 exam, this concept tests your ability to read a risk register and apply the risk score calculation to prioritize threats; a common trap is confusing the individual probability or impact values with the final score, so always multiply them. Remember the memory tip: “Multiply the odds and the damage to get the real risk.”
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.

Correct answer & explanation
✓
R003
Risk R003 has the highest risk score because the risk register shows a probability of 0.8 and an impact of 0.9, yielding a risk score of 0.72 (0.8 × 0.9). This is higher than R001 (0.5 × 0.7 = 0.35) and R002 (0.6 × 0.8 = 0.48). In project risk management, the risk score is calculated by multiplying probability and impact, and R003's product is the greatest.
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
The trap here is that candidates may incorrectly assume the highest probability or highest impact alone determines the risk score, rather than multiplying both factors, leading them to pick R002 (highest impact) or R001 (misreading values).

Detailed technical explanation
How to think about this question
The risk score is a quantitative measure derived from the formula Risk Score = Probability × Impact, where both factors are typically on a scale from 0.0 to 1.0. This calculation is foundational to the PMBOK Guide's risk assessment process, enabling prioritization of risks for response planning. In real-world projects, a risk with a score above 0.5 often triggers immediate mitigation actions, and R003's score of 0.72 would be considered high priority.

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.
