PSM II - Developing and Delivering Products Professionally Example Questions

Test your knowledge of Developing and Delivering Products Professionally

Question 1

A Scrum Team has been using the same Definition of Done for eight Sprints. During a Sprint Retrospective, a Developer suggests removing the 'documentation update' criterion because it slows them down. The Product Owner agrees, saying stakeholders care more about speed. As the Scrum Master, how should you facilitate this discussion?

Encourage the team to keep the criterion and instead find ways to streamline the documentation process so it takes less time each Sprint Help the team understand the long-term implications of removing criteria and encourage them to consider whether the criterion still serves product quality before deciding Recommend that the team replace the documentation criterion with a lighter alternative that still captures essential knowledge for future maintenance Support the team's autonomy by allowing them to vote on removing the criterion since the Definition of Done belongs to the Scrum Team as a whole

Correct Answer: Help the team understand the long-term implications of removing criteria and encourage them to consider whether the criterion still serves product quality before deciding

The correct answer reflects the Scrum Master's role as a facilitator and coach who helps the team make informed decisions by understanding the consequences of lowering quality standards, rather than directing the outcome or simply deferring to a vote.

Supporting a simple vote ignores the Scrum Master's coaching responsibility to ensure the team understands the implications of weakening their Definition of Done. Recommending a specific alternative is prescriptive and removes the team's ownership of the decision. Encouraging them to keep the criterion is also directive and undermines self-management by pre-determining the outcome.

The key concept tested is the Scrum Master's role in facilitating informed decision-making about the Definition of Done without being directive, ensuring transparency about quality trade-offs.

Question 2

An agile team maintains a 24/7 e-commerce platform. Currently, they use scheduled maintenance windows to release new increments. Users frequently complain about these disruptions, and the Product Owner wants a way to release updates seamlessly while ensuring a fast fallback option in case of critical failures. Which architectural infrastructure practice should the team adopt to address this requirement?

Establish a monolithic architecture breakdown strategy to deploy individual components independently during off-peak hours. Setup an immutable infrastructure container registry to ensure all servers are replaced sequentially with the new version. Use comprehensive automated acceptance tests to prevent degraded performance issues from reaching the live portal interface. Implement a blue-green deployment strategy to shift user traffic to the updated environment only after successful validation.

Correct Answer: Implement a blue-green deployment strategy to shift user traffic to the updated environment only after successful validation.

Blue-green deployment allows teams to release updates seamlessly with zero downtime by running two identical production environments and instantly re-routing traffic, providing an immediate fallback option if issues occur.

Immutable infrastructure replaces servers sequentially but does not inherently ensure zero downtime or instant rollback capabilities. Breaking down a monolith for off-peak deployment still relies on scheduled downtime windows and disrupts users. Automated acceptance tests are vital for quality assurance before a release but do not architecturally enable zero-downtime routing or fast fallbacks.

The key concept tested is advanced architectural deployment strategies for continuous delivery and high availability.

Question 3

A Scrum Team is working on a new feature. During refinement, a Developer mentions that the existing code in that area uses outdated patterns and will be harder to extend. The Product Owner says the feature is urgent and asks if they can just build on top of what exists. What should the Scrum Master do?

Advise the Developers to create a separate backlog dedicated to refactoring so the Product Owner can schedule it after the urgent feature ships Encourage the Developers to update the outdated patterns first and then begin the feature work in a subsequent Sprint to ensure quality Support the Product Owner's decision since they are accountable for maximizing value and the team should respect the urgency of the request Help the team and Product Owner understand the trade-off between building on fragile code now and the increased cost of future changes

Correct Answer: Help the team and Product Owner understand the trade-off between building on fragile code now and the increased cost of future changes

The Scrum Master should facilitate transparency by helping both the team and Product Owner understand the trade-off between short-term speed and long-term maintainability, enabling an informed decision rather than making the decision for them.

Creating a separate refactoring backlog artificially separates technical work from product work and defers necessary conversations. Insisting on refactoring first overrides the Product Owner's value judgment and ignores urgency. Simply deferring to the Product Owner without ensuring they understand the technical implications fails the Scrum Master's coaching responsibility, as the PO needs full transparency to make a truly informed decision about value maximization.

Key concept tested: facilitating informed decision-making through transparency about technical debt trade-offs.
