- A
Request a change request to update the cost baseline and budget.
The cost increase requires a change request to update the cost baseline through formal change control.
- B
Notify key stakeholders about the situation and the plan to proceed.
Stakeholders should be informed about the risk occurrence and the response being taken.
- C
Instruct the team to work overtime to recover the schedule.
Why wrong: Overtime may help schedule but does not address the vendor delay directly and may not be effective.
- D
Implement the contingency plan by engaging the alternative vendor.
The contingency plan exists for this risk; implement it as planned.
- E
Reject the vendor's notice and demand they meet the original deadline.
Why wrong: Demanding compliance without a viable alternative is unrealistic and may damage the relationship.
Quick Answer
The answer is to implement the contingency plan by engaging the alternative vendor, then assess the cost impact to update the cost baseline through change control, and finally communicate the situation to stakeholders. This sequence is correct because a contingency plan is pre-approved for execution when a risk trigger occurs, but any resulting cost impact must be formally integrated into the project budget via the Perform Integrated Change Control process, while transparent communication with stakeholders fulfills the Plan Communications Management requirement. On the PMP exam, this scenario tests your ability to distinguish between executing a planned response and the subsequent need for change management, as a common trap is to skip the cost baseline update or to delay implementation while seeking approval. The search intent keywords—contingency plan implement, cost impact, and communicate stakeholders—are directly embedded in this workflow. Remember the mnemonic ICA: Implement, Cost assess, Announce.
PMP Process — Managing Technical Aspects Practice Question
This PMP practice question tests your understanding of process — managing technical aspects. 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.
You are managing a large-scale construction project. A critical vendor has informed you that they will be delayed by two months due to a raw material shortage. This risk was identified and recorded in the risk register with a contingency plan to use an alternative vendor. However, the alternative vendor's materials are more expensive and will increase project costs by 10%. Which THREE actions should you take?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Request a change request to update the cost baseline and budget.
First, implement the contingency plan as it was pre-approved. Then, assess the cost impact to update the cost baseline through change control. Finally, communicate the situation to stakeholders. These steps align with PMI's risk and communication management.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related PMP NAT questions on configuration and troubleshooting.
