This PMP practice question tests your understanding of people — leading projects. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
A key vendor informs you that due to raw material shortages, they cannot deliver a critical component on time. This component is on the critical path. The risk register included this as a high-probability risk with a contingency plan to use an alternative supplier. What should you do FIRST?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Activate the contingency plan and engage the alternative supplier
D is correct because the risk was already identified, assessed as high-probability, and a contingency plan (alternative supplier) was documented in the risk register. When the risk occurs, the first action is to execute the pre-approved contingency plan, not to reanalyze or seek new approvals, as the plan was already vetted during risk planning.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Ask the project sponsor to approve the alternative supplier
Why it's wrong here
The contingency plan should have pre-approved actions; the PM can implement it.
✗
Replan the project schedule to accommodate the delay
Why it's wrong here
Replanning without using the contingency plan may cause unnecessary delays.
✗
Perform a new risk analysis to assess the impact
Why it's wrong here
The risk was already identified and planned; re-assessing may delay response.
✓
Activate the contingency plan and engage the alternative supplier
Why this is correct
Since the risk was identified and a contingency plan exists, the PM should implement it.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse the need for a new risk analysis or approval with the fact that the contingency plan was already approved and documented, leading them to waste time on unnecessary steps instead of executing the pre-planned response.
Detailed technical explanation
How to think about this question
In project risk management, a contingency plan is a pre-defined set of actions to be taken when a specific risk event occurs, and it is typically included in the risk register with a trigger condition. Activating the plan immediately upon trigger avoids schedule slippage on the critical path, as the alternative supplier should have been pre-qualified and ready to step in. This aligns with the PMBOK Guide's 'Implement Risk Responses' process, which emphasizes executing planned responses without delay.

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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
