The answer is that fast-tracking primarily increases the risk of rework. This occurs because fast-tracking compresses the schedule by executing tasks in parallel that were originally planned sequentially, which forces dependencies to overlap without the usual buffer for verification. When a predecessor task is not fully complete, a successor task may begin with incomplete or incorrect information, leading to errors that must be corrected later. On the CompTIA Project+ PK0-005 exam, this concept tests your understanding of schedule compression techniques and their trade-offs; a common trap is confusing fast-tracking with crashing, which adds cost rather than risk. To remember this, think of the phrase “parallel paths, parallel problems”—the more you overlap, the higher the chance you’ll have to redo work.
PK0-005 Project Life Cycle Phases Practice Question
This PK0-005 practice question tests your understanding of project life cycle phases. 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 project is in the executing phase. The project manager notices that the actual cost is consistently higher than planned, and the schedule is behind. After analyzing the situation, the project manager decides to fast-track some tasks. What is the primary impact of fast-tracking?

Correct answer & explanation
✓
It increases risk of rework
Fast-tracking involves performing tasks in parallel that were originally planned sequentially, which increases risk but can compress the schedule.
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.
✗
It reduces cost by eliminating tasks
Why it's wrong here
Fast-tracking does not eliminate tasks; it may increase coordination costs.
✓
It increases risk of rework
Why this is correct
Parallel execution can lead to rework if dependencies are not fully understood.
Clue confirmation
The clue word "primary" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
It immediately lowers resource costs
Why it's wrong here
Fast-tracking may require additional resources, potentially increasing costs.
✗
It decreases the project's scope
Why it's wrong here
Fast-tracking does not change scope; it changes 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.
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 PK0-005 NAT questions on configuration and troubleshooting.
