PK0-005 Risk Score Practice Question
Network Topology
A project manager reviews the following risk register: R1 (Vendor delay) has a probability of 0.8 and an impact of 0.6; R2 (Resource shortage) has a probability of 0.6 and an impact of 0.5; R3 (Technical failure) has a probability of 0.6 and an impact of 0.6; R4 (Scope creep) has a probability of 0.7 and an impact of 0.5. Which risk should the project manager prioritize for active monitoring and response?
⚠ Common exam trap
PK0-005 often tests the risk score calculation, and candidates may incorrectly prioritize the risk with the highest impact (R3) or highest probability alone, forgetting to multiply probability by impact.

Correct answer & explanation
✓
R1 - Vendor delay
R1 has the highest risk score when multiplying probability by impact: 0.8 × 0.6 = 0.48, which is higher than R2 (0.6 × 0.5 = 0.30), R3 (0.6 × 0.6 = 0.36), and R4 (0.7 × 0.5 = 0.35). Therefore, R1 should be prioritized for active monitoring and response. The project manager uses the risk score (probability × impact) to rank risks and focus attention on the highest exposure.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
R1 - Vendor delay
Why this is correct
It has the highest risk score and requires active monitoring.
- ✗
R3 - Technical failure
Why it's wrong here
Though impact is high, probability is low, and it's accepted.
- ✗
R4 - Scope creep
Why it's wrong here
It is being avoided, which may reduce priority compared to active risks.
- ✗
R2 - Resource shortage
Why it's wrong here
R2 scores 0.30, below R1's 0.48 and R3's 0.36, so it ranks third rather than first. Expected monetary value multiplication is the axis here. Resource shortage monitoring suits staffing plans where labour availability drives the schedule, but this register's probabilities and impacts place it behind higher-scoring risks.
