The answer is to initiate a change request to increase the cost baseline, documenting the risk response and vendor selection. This is correct because when a hybrid project risk response—such as the planned mitigation of identifying an alternative vendor—causes the cost baseline to be exceeded, formal change control must be triggered to protect the integrity of the performance measurement baseline. The hybrid nature of the project does not bypass the need for a documented change; the predictive phase still requires a controlled baseline adjustment. On the PMP exam, this scenario tests your understanding that risk responses are executed within the Perform Integrated Change Control process, and a common trap is to skip the change request and simply spend the extra budget. Remember the mnemonic “Risk Response + Baseline Break = Change Request First”—never approve a cost overrun without a formal change.
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 hybrid project with both predictive and agile components. A key risk from the risk register materializes: a critical vendor may go bankrupt, threatening delivery of a hardware component needed for the predictive phase. The risk response plan includes 'mitigate by identifying alternative vendors.' However, the only alternative vendor quotes a price that would exceed the project cost baseline by 10%. What should you do NEXT?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Initiate a change request to increase the cost baseline, documenting the risk response and vendor selection
Option B is correct because the risk response plan's mitigation strategy (identify alternative vendor) is being enacted, but since it exceeds the baseline, a change request is needed to adjust the cost baseline. Option A ignores the need for change control. Option C is reactive and may not be necessary. Option D prematurely escalates.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Proceed with the alternative vendor and inform the sponsor of the cost overrun after the fact
Why it's wrong here
Proceeding without change control violates the project management plan.
✓
Initiate a change request to increase the cost baseline, documenting the risk response and vendor selection
Why this is correct
Since the response exceeds the baseline, formal change control is required.
Related concept
Static NAT maps one inside address to one outside address.
✗
Accept the risk and hope the vendor recovers, avoiding the cost increase
Why it's wrong here
Acceptance is a valid response but not when a proactive response was planned and feasible.
✗
Escalate to the sponsor for a decision on whether to cancel the project
Why it's wrong here
Escalation to cancel is premature; a change request is the appropriate next step.
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.
