The answer is to analyze the impact on the critical path and evaluate options. This is correct because, when a supplier delays delivery, the project manager must first determine whether the delay actually affects the project’s overall completion date; only tasks on the critical path directly influence the schedule, so a two-week delay to a non-critical task might be absorbed by float, while a critical path delay demands a formal response. On the Certified Associate in Project Management CAPM exam, this scenario tests your understanding of schedule management and the principle that analysis precedes action—a common trap is jumping to fast-track or crash the schedule without first confirming the critical path impact. To remember this, think of the mnemonic “ACE”: Analyze the Critical path first, then Evaluate options.
CAPM Practice Question: Project Management Fundamentals and Core Concepts
This CAPM practice question tests your understanding of project management fundamentals and core concepts. 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.
A construction project is underway. The project manager receives a report that the concrete supplier will deliver late, causing a two-week delay. The project has no schedule reserve. What is the best course of action?

Correct answer & explanation
✓
Analyze the impact on the critical path and evaluate options
Option D is correct because the project manager should first analyze the impact on the critical path before deciding on a response. The other options are premature without analysis.
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.
✗
Inform the sponsor and request a schedule extension
Why it's wrong here
Extension should be considered only after analysis.
✗
Immediately crash the schedule by adding resources to critical path activities
Why it's wrong here
This is a possible response but should be based on analysis first.
✗
Fast-track the remaining activities to recover the delay
Why it's wrong here
Fast-tracking may increase risk and should be evaluated.
✓
Analyze the impact on the critical path and evaluate options
Why this is correct
Analyzing impact is the first step in the change control or risk response process.
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.
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 CAPM NAT questions on configuration and troubleshooting.
