The correct first step is to assess the impact on the critical path and overall schedule. This is because, in a hybrid project environment, the critical path represents the longest sequence of dependent tasks that determines the project’s finish date, and losing a key team member responsible for those tasks introduces immediate schedule risk. Before any corrective action can be taken—whether it’s reallocating resources, fast-tracking, or crashing—the project manager must quantify the delay and understand which specific path activities are affected. On the PMP exam, this scenario tests your ability to prioritize analysis over reaction, a common trap where candidates jump to hiring or reassigning staff without first evaluating the schedule variance. A useful memory tip is “Assess before you address”—always measure the disruption to the critical path before deciding on a response.
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 using a hybrid approach. During the execution phase, one of your key team members, a senior engineer, resigns unexpectedly. This engineer was responsible for critical path tasks. What is the FIRST thing you should do?
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
✓
Assess the impact on the critical path and overall schedule
Option D is correct. The PM should first evaluate the impact on the schedule and critical path before taking further action. Options A, B, and C are premature without understanding the impact.
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.
✗
Immediately request a replacement from HR
Why it's wrong here
First assess the impact before requesting a replacement.
✗
Update the risk register and plan for a schedule delay
Why it's wrong here
First assess impact, then update risk register.
✗
Reassign the engineer's tasks to other team members
Why it's wrong here
This should be done after impact assessment.
✓
Assess the impact on the critical path and overall schedule
Why this is correct
Understanding the impact is the first step in determining the appropriate response.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
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.
