The answer is fast-tracking activities on the critical path. This technique is correct because schedule compression without cost increase must avoid adding resources, which is the hallmark of crashing; fast-tracking instead re-sequences tasks to run in parallel, leveraging existing resources at no extra cost, though it does increase risk. On the PMP exam, this scenario tests your ability to distinguish between the two compression techniques under a strict cost constraint—a common trap is to choose crashing when the sponsor demands speed, but the key is that crashing always adds cost for extra resources. Remember the memory tip: “Fast-track is free but risky; crashing costs cash.”
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 the project manager for a large infrastructure project. During a routine check, you discover that the project's SPI is 0.85 and the CPI is 0.90. The project sponsor is concerned about the schedule delay and asks you to compress the schedule without increasing costs. Which technique is BEST suited for this situation?

Correct answer & explanation
✓
Fast-tracking activities on the critical path
Option A is correct because crashing involves adding resources to critical path activities, which typically increases cost. Since the sponsor wants no cost increase, crashing is not appropriate. Fast-tracking can be done at no additional cost but may increase risk.
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.
✗
Reduce the scope of the project
Why it's wrong here
Reducing scope would require a change request and may not be acceptable to the sponsor without formal approval.
✓
Fast-tracking activities on the critical path
Why this is correct
Fast-tracking performs activities in parallel and typically does not increase cost, though it may increase risk.
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.
✗
Apply resource leveling to smooth resource usage
Why it's wrong here
Resource leveling can actually increase schedule duration, not compress it.
✗
Crashing the critical path by adding more resources
Why it's wrong here
Crashing usually increases cost, which contradicts the sponsor's constraint of no cost increase.
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.
