The answer is crashing and fast-tracking, as these are the two appropriate schedule compression techniques recognized in the PMP framework. Crashing works by adding resources to critical path activities to reduce duration, while fast-tracking involves performing tasks in parallel that were originally planned sequentially. On the Project Management Professional PMP exam, this question tests your ability to distinguish schedule compression from resource optimization or scope changes—common traps include selecting resource leveling or scope reduction, which are not compression methods. A frequent exam scenario presents a delay caused by external factors, like regulatory changes, where you must choose techniques that do not alter project scope. Remember the memory tip: “Crash with cash, fast-track with overlap”—crashing costs more by adding resources, and fast-tracking risks rework by overlapping activities.
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 facing significant schedule delays due to unforeseen regulatory changes. You need to compress the schedule. Which TWO techniques are appropriate for schedule compression?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Fast-tracking: performing activities in parallel that were originally sequential
Crashing and fast-tracking are the two main schedule compression techniques. Crashing adds resources to critical path activities, while fast-tracking performs activities in parallel. Resource leveling is for resource optimization, and scope reduction is a scope change.
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.
✓
Fast-tracking: performing activities in parallel that were originally sequential
Why this is correct
Fast-tracking can reduce schedule but may increase risk.
Related concept
Static NAT maps one inside address to one outside address.
✓
Crashing: adding resources to critical path activities
Why this is correct
Crashing adds resources to shorten duration, often increasing cost.
Related concept
Static NAT maps one inside address to one outside address.
✗
Adding buffers to the schedule
Why it's wrong here
Adding buffers increases the schedule, not compress it.
✗
Resource leveling: smoothing resource demand to avoid peaks
Why it's wrong here
Resource leveling typically extends the schedule, not compresses it.
Scope reduction requires a change request and is not a schedule compression technique per se.
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.
