The answer is crashing. Crashing is the best schedule compression technique when additional budget is available because it focuses on adding resources—such as overtime, extra staff, or specialized equipment—directly to critical path activities to reduce overall project duration. Unlike fast tracking, which runs tasks in parallel and risks rework, crashing trades cost for time and is explicitly designed for scenarios where budget constraints are not the primary limitation. On the PMP exam, this question tests your ability to distinguish between schedule compression methods under specific constraints; a common trap is confusing crashing with fast tracking or assuming resource leveling can shorten the schedule. Remember the memory tip: “Crash the critical path with cash”—if you have budget, you crash.
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.
Your project is behind schedule, and you need to compress the schedule. The critical path has been identified. What is the BEST schedule compression technique to use if you have additional budget available?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Why wrong: Fast tracking performs activities in parallel, which can increase risk without additional cost, but the question specifies having additional budget.
B
Crashing
Crashing adds resources to critical path activities to shorten duration, typically with increased cost.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Crashing
Crashing adds resources to critical path activities and is appropriate when budget allows. Option A is correct. Option B does not compress schedule. Option C may not reduce duration. Option D is not defined.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

For each option: why learners choose it and why it is or isn't the right answer here.
✗
Fast tracking
Why it's wrong here
Fast tracking performs activities in parallel, which can increase risk without additional cost, but the question specifies having additional budget.
✓
Crashing
Why this is correct
Crashing adds resources to critical path activities to shorten duration, typically with increased cost.
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.
✗
Resource smoothing
Why it's wrong here
Resource smoothing adjusts activities without changing critical path length.
✗
Resource leveling
Why it's wrong here
Resource leveling addresses resource constraints but may increase schedule.
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.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. Your project is running behind schedule. You need to compress the schedule without significantly increasing cost. Which TWO techniques should you consider?
medium
✓ A.Add resources from non-critical path activities to critical path tasks
✓ B.Fast-track activities by performing them in parallel
C.Eliminate non-essential deliverables without approval
D.Reduce quality standards to save time
E.Reduce project scope without change control
Why A: Option A (fast-tracking) and Option D (adding resources from non-critical path) are valid schedule compression techniques. Fast-tracking performs activities in parallel; adding resources (crashing) can be done selectively without major cost impact if resources are available. Option B changes scope without approval. Option C reduces quality. Option E reduces scope.
