The correct answer is D – Provide a delivery range based on the team ' s estimated velocity.

In Agile, planning is iterative and inherently uncertain. Rather than committing to a fixed schedule, it is best practice to provide a forecasted delivery window based on the team’s actual measured velocity. This reflects the inspect-and-adapt mindset of Agile.

From the PMI Agile Practice Guide:

“Agile teams forecast delivery using velocity ranges derived from completed work. Ranges reflect uncertainty and promote realistic expectations with stakeholders.”

(PMI Agile Practice Guide, Section 5.4 – Adaptive Planning)

Mike Griffiths affirms:

“Planning with ranges rather than fixed commitments respects the uncertainty of estimates and the empirical nature of Agile delivery. Forecasts should be based on velocity trends and updated iteratively.”

(Mike Griffiths, PMI-ACP Exam Prep Book, Chapter 5 – Adaptive Planning)

Why the other options are less suitable:

A suggests triangulating data but wrongly implies a precise commitment.

B is more of a work preparation activity, not a planning technique.

C (analogous estimation) is better suited for initial planning, not for an in-progress agile project with real velocity data.

Answer: D

══════════════════════════════════════════════════

The correct answer is D — Identify this as a risk, decide on the response, and prioritize spike to determine the solution on the product backlog.

A spike is a time-boxed research activity used in Agile to explore potential solutions to uncertainty. The architectural concern is a technical risk, and it ' s best addressed by formally identifying it, analyzing potential responses, and scheduling a spike as a backlog item to investigate solutions.

PMI Agile Practice Guide:

“Spikes are stories used for time-boxed research and exploration when the team needs more information to understand technical or functional uncertainty.”

(PMI Agile Practice Guide, Section 5.2 – Types of Backlog Items)

Mike Griffiths:

“Agile risk management integrates spikes and prioritization. When risk is detected, the team should identify it transparently and explore mitigation or investigation through a spike.”

(PMI-ACP Exam Prep, Chapter 6 – Problem Detection and Resolution)

Incorrect options:

A skips backlog prioritization and team alignment.

B deflects the issue without analysis.

C ignores risk and blindly follows the existing priority.

Answer: D

—

When the team is uncertain about a technical solution, a spike—a timeboxed research task—is used to explore possible approaches. The PMI Agile Practice Guide (Section 5.2: Spikes) and Mike Griffiths’ PMI-ACP Exam Prep Book (Chapter 6: Adaptive Planning) recommend spikes as a formal way to explore unknowns and reduce risk in the backlog.

Option B is correct: spikes provide structure for resolving uncertainty.

Option A ignores the technical risk.

Option C disrupts team structure and ownership.

Option D defers the problem without seeking resolution.

The correct answer is C – Initiate an estimation session because agile planning is iterative and collaborative. When delivery timing is in question, especially during a release planning session, the team must first estimate the size of the work (epics and user stories). Once estimates are made (often using story points or relative sizing techniques), velocity can be used to forecast delivery timelines.

From the PMI Agile Practice Guide:

“Estimation is typically performed at the beginning of a release or iteration planning session to determine how much work can be completed. Teams use estimation to size items and then apply their known or projected velocity to forecast completion.”

(PMI Agile Practice Guide, Section 5.3 – Estimation and Velocity)

Mike Griffiths’ PMI-ACP Exam Prep Book also states:

“Before making any delivery commitments, teams should first engage in collaborative estimation to understand the scope and effort of the work. These estimates then inform velocity-based forecasting.”

(Mike Griffiths, Chapter 5 – Adaptive Planning)

Why the other options are incorrect:

A – Scrum Masters do not estimate work; estimation is a team activity.

B – You cannot determine deliverables based on velocity until the work has been estimated.

D – Historical data can support forecasting but must be preceded by proper estimation of current backlog items.
