EXAM
2026 Edition | Questions 1–250 | Answers + Explanations
Q1. Which coaching competency distinguishes a DevOps coach from a consultant? A) Delivering a pre‑defined solution B) Facilitating the team’s own discovery of solutions C) Managing project timelines directly D) Writing code for the team Answer: B) Facilitating the team’s own discovery of solutions Explanation: A coach enables the team to find answers themselves, whereas a consultant typically provides ready‑made solutions. This is the fundamental distinction—coaching builds capability rather than delivering fixes.
Explanation: Paraphrasing (summarizing in your own words) shows you have understood the speaker and encourages deeper dialogue. Planning responses or interrupting disrupts the listening process.
Q4. Ethical coaching requires maintaining confidentiality. Which scenario breaches this principle? A) Sharing a team’s post‑mortem findings only with senior leadership B) Documenting anonymized lessons learned in a public wiki C) Discussing a specific individual’s performance issue with another team without consent D) Asking for consent before publishing coaching outcomes Answer: C) Discussing a specific individual’s performance issue with another team without consent Explanation: Revealing personal performance details without explicit consent violates confidentiality. Anonymized data or obtaining permission before sharing maintains ethical boundaries.
Q5. According to Westrum’s typology, a “Generative” organization is characterized by: A) Strict hierarchy and blame culture B) Information flow and learning orientation C) Resistance to change and silos D) Minimal communication across departments Answer: B) Information flow and learning orientation Explanation: Generative cultures promote active information sharing, cross-functional collaboration, learning from failures, and continuous improvement. They stand in contrast to bureaucratic (rule-bound) or pathological (power-driven) cultures.
Q6. Amy Edmondson’s concept of psychological safety primarily aims to: A) Increase individual competition B) Reduce the need for documentation C) Encourage speaking up without fear of punishment D) Enforce strict adherence to processes
Q8. The First Way of DevOps emphasizes: A) Amplifying feedback loops B) The flow of work from development to operations to customer C) A culture of experimentation and learning D) Strict separation of duties Answer: B) The flow of work from development to operations to customer Explanation: The First Way focuses on optimizing the speed and quality of work as it flows through the entire value stream—from concept to cash, or from left to right.
Q9. The Second Way of DevOps emphasizes: A) Continuous integration B) Fast, frequent feedback loops C) Blameless post-mortems D) Infrastructure as Code
Answer: B) Fast, frequent feedback loops Explanation: The Second Way creates feedback loops from right to left—from operations back to development, from customers back to the team—enabling problems to be detected and fixed quickly.
Q10. Which statement best describes the Theory of Constraints (ToC) in a delivery pipeline? A) All steps should be equally balanced B) Identify and improve the single biggest bottleneck (“Herbie”) C) Eliminate all manual testing D) Automate every task regardless of value Answer: B) Identify and improve the single biggest bottleneck (“Herbie”) Explanation: ToC concentrates on the most limiting factor (the bottleneck) to improve overall throughput. Improving non- bottlenecks yields no overall gain. “Herbie” is a term for the constraint.
Explanation: CALMS = Culture, Automation, Lean, Measurement, Sharing. “Metrics” is the correct term, referring to data-driven decision-making. (Note: Some variations use “Measurement.”)
Q13. Which CI/CD practice supports trunk‑based development? A) Long‑lived feature branches merged monthly B) Frequent commits directly to mainline with short‑lived feature toggles C) Separate release branches for each environment D) Manual integration after each sprint Answer: B) Frequent commits directly to mainline with short‑lived feature toggles Explanation: Trunk-based development encourages developers to merge small, frequent changes directly to the main branch (trunk), often using feature toggles to hide incomplete work. This reduces merge conflicts and enables continuous integration.
Q14. Shift‑Left testing primarily aims to: A) Delay security reviews until production B) Perform testing early in the development lifecycle C) Increase the number of post‑release patches D) Move testing responsibilities to operations only Answer: B) Perform testing early in the development lifecycle Explanation: “Shifting left” means moving testing (including security and quality checks) earlier in the development process—from right (production) to left (design/coding). This finds defects when they are cheaper and easier to fix.
Q15. Conway’s Law suggests that system architecture mirrors: A) The programming language used B) The organization’s communication structure C) The hardware platform D) The market demand Answer: B) The organization’s communication structure
A) Enforce strict governance policies B) Facilitate informal knowledge sharing across teams C) Assign tasks to individual contributors D) Replace formal training programs Answer: B) Facilitate informal knowledge sharing across teams Explanation: CoPs bring together practitioners from different teams to share expertise, best practices, tools, and lessons learned. They are voluntary, peer-driven, and focus on learning rather than delivery.
Q18. In a retrospective at scale, which technique helps aggregate insights from many teams? A) Individual team retrospectives only B) A single all‑hands meeting without breakout groups C) A “Scrum of Scrums” or “Meta‑Retrospective” D) Ignoring team‑level feedback Answer: C) A “Scrum of Scrums” or “Meta‑Retrospective”
Explanation: Meta‑retrospectives collect and synthesize findings across multiple teams, identifying systemic patterns that individual team retrospectives might miss. This is critical for scaling agile and DevOps practices.
Q19. An Obeya room is used for: A) Private one‑on‑one coaching sessions B) Visual management of large‑scale initiatives C) Storing legacy code D) Hosting daily stand‑ups only Answer: B) Visual management of large‑scale initiatives Explanation: Obeya (Japanese for “big room”) centralizes visual artifacts such as metrics, progress charts, impediment lists, and strategic goals. It improves alignment, transparency, and decision- making across large programs.
Answer: B) Delivering end‑to‑end value for a particular product or service stream Explanation: Stream-aligned teams are structured around a flow of work (value stream) and have the autonomy to deliver value directly to customers without handoffs to other teams.
Q22. In Team Topologies, an “Enabling Team” helps: A) Stream-aligned teams by providing specialized capabilities and coaching B) Manage infrastructure without interacting with other teams C) Replace all other teams D) Focus only on legacy maintenance Answer: A) Stream-aligned teams by providing specialized capabilities and coaching Explanation: Enabling teams consist of specialists (e.g., security, database, testing) who assist stream-aligned teams in adopting new practices or technologies, then step away once capability is built.
Q23. The “Third Way” of DevOps emphasizes: A) Strict adherence to documented processes B) Continuous learning and experimentation C) Maximizing the number of releases per day D) Centralized decision‑making Answer: B) Continuous learning and learning Explanation: The Third Way fosters a culture of ongoing learning, experimentation, taking risks, and learning from failures. It ensures that lessons from the First and Second Ways are institutionalized.
Q24. The primary goal of DevOps in modern software development is: A) To increase developer independence B) To improve collaboration between development and operations for faster delivery C) To replace traditional project management D) To eliminate testing processes
Q26. Which driver is most influential in organizations adopting DevOps? A) Reducing team collaboration B) Increasing manual processes C) Accelerating delivery and improving quality D) Eliminating testing altogether Answer: C) Accelerating delivery and improving quality Explanation: Organizations adopt DevOps primarily to deliver value faster, with higher quality and reliability, by automating manual processes and fostering collaboration.
Q27. What is a typical characteristic of an organization at the initial stage of DevOps maturity? A) Fully automated deployment pipeline B) Manual deployments and siloed teams C) Continuous feedback and rapid iteration
D) High level of cloud integration Answer: B) Manual deployments and siloed teams Explanation: Early-stage organizations often rely on manual deployment processes, with development and operations functioning in separate silos, lacking automation and continuous delivery practices.
Q28. Which step is essential in the DevOps transformation framework? A) Ignoring organizational culture B) Establishing a clear roadmap and strategic alignment C) Avoiding leadership involvement D) Focusing only on tools Answer: B) Establishing a clear roadmap and strategic alignment Explanation: A successful DevOps transformation requires a clear, prioritized roadmap aligned with business strategy. Tools alone cannot drive change; strategy, leadership, and culture are critical.
