The answer is to submit a change request to fix the defect, assessing the impact on schedule and cost, and obtain approval. This is correct because quality is a non-negotiable constraint in project management; releasing software with a critical defect that could cause data loss introduces unacceptable risk to the organization and stakeholders, far outweighing the cost of a one-week delay. The Project Management Professional PMP exam tests your understanding that even when behind schedule, the project manager must follow the formal change control process rather than making unilateral decisions—a common trap is choosing to “fix it immediately” without approval, which violates the PMBOK’s integrated change control. When a critical defect found during testing demands a best course of action, always prioritize risk management over schedule pressure. Memory tip: think “CRITICAL = Change Request, Impact, Then Approval, Communicate, Act, Log”—the CRITICAL mnemonic ensures you never skip the formal process.
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 project to develop a mobile app. During the testing phase, a critical defect is found that could cause data loss. The team estimates it will take one week to fix, but the project is already two weeks behind schedule. What is the BEST course of action?

Correct answer & explanation
✓
Submit a change request to fix the defect, assessing the impact on schedule and cost, and obtain approval
Quality is a key constraint; releasing with a critical defect poses high risk. The PM should follow the change control process to assess the impact and get approval for the fix.
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.
✗
Release the app as scheduled and patch the defect later to avoid further delays
Why it's wrong here
Releasing with a critical defect that could cause data loss is unacceptable and risks reputation.
✓
Submit a change request to fix the defect, assessing the impact on schedule and cost, and obtain approval
Why this is correct
Following change control ensures the decision is informed and documented.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
Escalate to the sponsor and ask for a decision on whether to fix or release
Why it's wrong here
The PM should analyze and recommend; simply escalating without analysis is not proactive.
✗
Fix the defect immediately and update the schedule without formal approval
Why it's wrong here
Fixing without approval bypasses change control; the schedule change should be evaluated.
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.
