- A
Add buffer time to the sprint plan to accommodate potential rework
Why wrong: Adding buffer does not address the root cause of unclear requirements.
- B
Instruct the team to proceed with their best interpretation of requirements
Why wrong: Proceeding without clarification increases rework; the PM should facilitate clarity.
- C
Introduce a requirements clarification step before each sprint planning
An upfront clarification step helps ensure requirements are understood before the sprint begins.
- D
Work with the product owner to implement one of the team's suggested improvements in the next sprint
Implementing improvements based on retrospective findings is a core agile practice.
- E
Ensure the product owner attends all sprint planning and grooming sessions to clarify requirements
Product owner involvement is crucial for clarifying requirements and reducing rework.
Quick Answer
The correct actions are ensuring the product owner attends all sprint planning and grooming sessions, implementing only one improvement per sprint, and adding a requirements clarification step before development begins. These three choices directly address the root cause of unclear requirements by improving communication and process discipline, rather than applying superficial fixes like adding buffer time or bypassing the product owner. On the PMP exam, this scenario tests your understanding of the Scrum Master’s role in facilitating transparency and continuous improvement within the Agile framework, often appearing as a trap where candidates confuse a schedule buffer with a real solution. A common memory tip is to remember that the Scrum Master protects the process, not the timeline—so any option that avoids the product owner or adds slack without fixing the input is automatically wrong. Think “Clarify, Commit, Improve” to recall that you must clarify requirements, commit to one change per sprint, and improve the grooming process.
PMP People — Leading Projects Practice Question
This PMP practice question tests your understanding of people — leading projects. 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.
During a sprint retrospective, the team identifies that unclear requirements from the product owner are causing rework. The team suggests improvements. Which THREE actions should the project manager (Scrum Master) take?
Answer choices
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
Introduce a requirements clarification step before each sprint planning
Options A, C, and D are correct because implementing one improvement per sprint, ensuring the product owner participates, and adding a requirements clarification step address the root cause. Option B is incorrect because adding buffer time does not solve the root cause. Option E is incorrect because bypassing the product owner violates the Scrum framework.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

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 PMP NAT questions on configuration and troubleshooting.
