PK0-005 Practice Question: Refer to the exhibit
Exhibit
Risk Register Risk ID | Description | Probability | Impact | Score | Response R001 | Resource shortage | 0.6 | High | 0.54 | Mitigate R002 | Vendor delay | 0.3 | Medium | 0.18 | Transfer R003 | Scope creep | 0.8 | High | 0.64 | Accept
Refer to the exhibit. Based on the risk register, which risk has the highest risk score?
⚠ Common exam trap
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).

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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
R001
Why it's wrong here
R001's score derives from multiplying its likelihood and impact values in the register; if that product falls below the highest-scoring entry, it cannot be the answer. It tempts because a high-impact or high-probability rating alone can look dominant, yet the score column, not either factor separately, determines ranking.
- ✓
R003
Why this is correct
R003 carries the highest risk score because its probability and impact ratings multiply to the greatest value in the register. Unlike risks with lower likelihood or milder consequences, R003's combined exposure exceeds every other entry, satisfying the stem's requirement to identify the risk with the maximum calculated score.
- ✗
All risks have the same score
Why it's wrong here
The exhibit's register lists differing probability and impact values, so identical scores cannot hold. It is tempting when several risks share a similar rating, but the risk score is probability multiplied by impact, and the register shows distinct products yielding one highest value.
- ✗
R002
Why it's wrong here
R002's likelihood-times-impact product is lower than the top-scoring risk in the register, so it cannot rank highest. It tempts because a severe impact rating draws attention, but the score column combines both factors; a moderate likelihood paired with that impact yields a lower total than the leading entry.
