- A
Crash activity X to gain 5 days, then accept the 15-day delay and request a schedule baseline change.
Why wrong: Does not maximize recovery; better to attempt more compression first.
- B
Implement only the fast-tracking option to save 10 days, then accept the remaining 10-day delay.
Why wrong: Sponsor likely wants full recovery; 10-day delay may be unacceptable.
- C
Implement only the crashing option to save 5 days, and then use management reserves to absorb the remaining 15 days.
Why wrong: Insufficient recovery; using reserves without exhausting other options is not optimal.
- D
Fast-track activities Y and Z to gain 10 days, crash activity X to gain 5 days, then negotiate a schedule change for the remaining 5 days.
Combines two compression techniques to recover most of the delay, then formally adjusts the schedule.
Quick Answer
The best integrated approach is to fast-track activities Y and Z to gain 10 days, crash activity X to gain 5 days, and then negotiate a schedule change for the remaining 5 days. This combination directly addresses the 20-day delay on the critical path by using both schedule compression techniques: fast-tracking overlaps sequential tasks to save time at the cost of increased risk, while crashing adds resources or overtime to critical path activities for a fixed cost. On the CAPM exam, this scenario tests your ability to apply schedule recovery and crashing and fast tracking concepts under the Predictive plan-based methodology, where the critical path has zero float and every day lost must be recovered. A common trap is choosing only one technique, which is insufficient for a 20-day gap, or accepting the delay outright without exhausting compression options. Remember the memory tip: “Fast for risk, crash for cost, then negotiate the rest.”
CAPM Predictive Plan-Based Methodologies Practice Question
This CAPM practice question tests your understanding of predictive plan-based methodologies. 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 the project manager for a large infrastructure project using a predictive plan-based methodology. The project has a critical path duration of 200 days. After 50 days of execution, a major delay occurs on a critical path activity due to unforeseen ground conditions, adding 20 days to that activity. The project has no float on the critical path. The sponsor requests a recovery plan to bring the project back on schedule. The team proposes two options: (1) crash activity X on the critical path by adding overtime, costing $10,000 and saving 5 days; (2) fast-track activity Y and Z by starting Y earlier, saving 10 days but increasing risk. What is the BEST integrated approach?

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
Fast-track activities Y and Z to gain 10 days, crash activity X to gain 5 days, then negotiate a schedule change for the remaining 5 days.
With a 20-day delay, the best approach combines fast-tracking (10 days) and crashing (5 days) to recover 15 days, then negotiate a schedule change for the remaining 5 days. Option D is correct. Option A only fast-tracks, insufficient. Option B only crashes, insufficient. Option C crashes and accepts, delaying completion.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

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.
