NEW QUESTION # 12
Which statement is NOT TRUE?
- A. Continuous Integration requires developers commit code to trunk at least daily
- B. Continuous Delivery ensures software is always in a releasable state
- C. Waterfall approaches can take advantage of continuous integration and test-driven development practices
- D. Continuous Deployment requires a manual push button
Answer: D
Explanation:
Let's clarify what these terms mean in DevOps:
* Continuous Integration (CI):Developers integrate code into a shared repository frequently (ideally daily), with each integration automatically verified by tests.
* Continuous Delivery (CD):Ensures software is always in a releasable state. Every change can be deployed to production, but the deployment itself may be a manual decision.
* Continuous Deployment:Every change that passes automated tests is automatically deployed to production,withoutmanual intervention.
Why is D ("Continuous Deployment requires a manual push button") NOT TRUE?
BecauseContinuous Deploymentis aboutno manual intervention-once code passes all tests, it's automatically pushed live. Manual deployment is a feature of Continuous Delivery, not Continuous Deployment.
Extract-style reference:
"Continuous Deployment means that every change goes through the pipeline and is automatically put into production, resulting in many production deployments every day."
-Accelerate: The Science of Lean Software and DevOps, Jez Humble & Nicole Forsgren DevOps Foundation v3.6distinguishes between Continuous Delivery (manual trigger) and Continuous Deployment (fully automated).
NEW QUESTION # 13
Successful DevOps relies on the adoption and integration of multiple frameworks including:
- A. Agile Service Management, Change Management, and Release Management
- B. Value Stream Management, Lean, Agile
- C. A shared vision, goals, and incentives
- D. Agile, ITSM, and Lean
Answer: D
Explanation:
DevOps is not a standalone framework-it draws from several methodologies and frameworks to achieve its goals. PeopleCert emphasizes the integration of:
* Agilefor iterative delivery, customer collaboration, and responsiveness
* ITSMfor effective service delivery and operational stability
* Leanfor waste elimination, flow optimization, and continuous improvement WhileAlists relevant processes, they are subsets rather than foundational frameworks.Cdescribes cultural alignment but is not a set of frameworks.Dincludes valuable concepts but does not match the official trio highlighted in PeopleCert's materials.
Thus,Bis correct.

NEW QUESTION # 14
Updates to a complex critical business service are released every calendar quarter. The business would like to increase the frequency of releases for this service.
Why would segmenting the service into microservices help to improve the frequency of release?
- A. Microservices are always open source so they can be modified frequently to meet business requirements
- B. Microservices can be built quickly to correct or remove errors in the primary system
- C. Microservices are less expensive and therefore can be built and released more frequently
- D. Microservices create a service architecture built on smaller modules that can be updated independently without affecting the primary system
Answer: D
Explanation:
Microservices architecturebreaks down applications into small, independent, loosely coupled services that can be developed, tested, and deployed independently.
* Why does this improve release frequency?Each microservice can be updated, tested, and deployed on its own, reducing the risk and coordination overhead associated with monolithic releases.
* This allows for faster feedback and more frequent delivery of value to users.
Extract-style reference:
"Microservices enable teams to deploy independently, reduce deployment risk, and increase release frequency by decoupling services."

- B. Common workspaces
- C. Hackathons
- D. Simulations
Answer: A
Explanation:
PeopleCert outlines multiple methods to encourage sharing and collaboration:
* A: Common workspaces promote informal communication and rapid problem-solving.
* B: Hackathons provide an engaging environment for innovation, cross-functional teamwork, and sharing solutions.
* C: Simulations (e.g., Game Days) allow teams to practice scenarios, learn from each other, and share insights in a low-risk setting.
Each of these fosters trust, transparency, and mutual learning. Using them together can amplify cultural change and skill growth.
Thus,D-All of the above-is correct.

NEW QUESTION # 16
Why is organizational culture so critical to successful DevOps?
- A. It represents the way teams are organized in their work environment
- B. It represents the strategic direction of the organization
- C. It represents the way people think and behave in their work environment
- D. It represents the way automation will be introduced into their organization
Answer: C
Explanation:
In DevOps,culturerefers to the shared values, beliefs, and behaviors that influence how people work together.
PeopleCert highlights culture as the foundation for collaboration, trust, and open communication-critical for breaking down silos and enabling continuous delivery.
OptionAbest captures this definition: culture reflects theway people think and behavein their daily work, including attitudes toward experimentation, problem-solving, and collaboration.
While team structure (B), automation strategy (C), and strategic direction (D) are important, they are outcomes or enablers that depend on the underlying culture. Without the right cultural foundation, DevOps practices and tools will not achieve their full potential.

NEW QUESTION # 17
An organization is architecting a DevOps toolchain that includes products from both open source and proprietary software providers.
Which of the following is necessary for applications within the toolchain to connect efficiently and effectively?
- A. Application Programming Interfaces
- B. Containers
- C. Open source applications
- D. Microservices
Answer: A
Explanation:
ADevOps toolchainis an integrated set of tools that supports the entire software delivery lifecycle-planning, coding, building, testing, releasing, deploying, operating, and monitoring. Regardless of whether tools are open source or proprietary, their ability to work together depends onApplication Programming Interfaces (APIs).
APIs define how different software components communicate and exchange data. In a DevOps context, APIs enable:
* Automation by allowing tools to trigger actions in other tools
* Data flow between systems (e.g., CI pipelines updating ticketing systems)
* Integration across heterogeneous environments
A(open source applications) is about licensing, not integration.B(containers) package and run applications consistently but do not inherently integrate tools.D(microservices) is an architectural style for applications, not the integration mechanism between delivery tools.
Therefore,C-APIs-are essential for efficient, effective toolchain integration.

NEW QUESTION # 18
How do shortened feedback loops PRIMARILY improve IT's performance?
- A. They ensure a faster flow between Dev and Ops
- B. They encourage learning and experimentation
- C. They help to create and share knowledge when needed
- D. They create a value stream map
Answer: A
Explanation:
According to PeopleCert DevOps Foundation v3.6, theSecond Wayof DevOps focuses on creating and amplifyingfeedback loops. The primary purpose of shortening these loops is toaccelerate the flow of work and informationbetween all stages of the delivery pipeline, especially between Development and Operations.
When feedback loops are short, defects, performance issues, and risks can be identified and resolved earlier in the process, preventing costly delays and large-scale rework. This supportsfaster, safer releasesand improves the organization's responsiveness to customer needs.
WhileA(learning) andD(knowledge sharing) are important benefits of feedback loops, they aresecondary outcomes. The main, direct effect is improvingflow efficiency-ensuring that handoffs between Dev and Ops happen smoothly, quickly, and with higher quality.
OptionC(value stream mapping) is a useful Lean practice to identify delays and bottlenecks, but it is a diagnostic tool, not the primary improvement gained from shortening feedback loops.
Thus, the correct answer isB-shortened feedback loops primarily improve IT performance by ensuringfaster flowbetween Development and Operations.

NEW QUESTION # 20
Which statement about deployment success rate is CORRECT?
- A. May apply to multiple environments, not just production
- B. Is the same as change success rate
- C. Is used to measure application reliability and stability
- D. Applies only to production
Answer: A
Explanation:
Deployment success ratemeasures the proportion of deployments that meet their objectives without causing incidents, rollbacks, or degraded service. PeopleCert notes this metric is not limited to production-it can be applied to any environment where deployments occur (staging, testing, pre-prod).
Ais incorrect because focusing only on production misses valuable insights from earlier environments.Cis partially correct-success rate can inform reliability-but reliability is more broadly measured with other metrics like availability and MTTR.Dis incorrect becausechange success ratetypically includes all changes, not just deployments.
Therefore,Bis the accurate statement.

NEW QUESTION # 21
Why are feedback loops important for improving DevOps capabilities?
- A. Trust grows
- B. Information is not amplified
- C. Sharing is prevented
- D. They drive more unplanned work
Answer: A
Explanation:
In the PeopleCert DevOps framework, feedback loops are essential for creatingtrustbetween teams. When feedback is timely, accurate, and acted upon, teams see that issues are addressed quickly, leading to increased confidence in the process and in each other.
High-trust environments promote openness, knowledge sharing, and collaborative problem-solving. This encourages teams to raise issues early and experiment with improvements without fear of blame.
OptionsA,B, andDdescribe negative effects that actually occur when feedback loops areabsentor ineffective.
Well-designed loops reduce unplanned work, promote sharing, and amplify important information to the right people.
Therefore,C-trust grows-is the correct answer.

NEW QUESTION # 22
Learning organizations understand that not embedding learning into the culture of an organization creates cultural debt.
Which of the following are characteristics of high performing organizations?
- A. Individualism
- B. Employees & Leadership Committed to Learning
- C. Change Management Team requiring Training
- D. Incentive Plans offered but frowned upon being used
Answer: B
Explanation:
High-performing organizationsembed learning into their culture, which leads to continuous improvement, innovation, and adaptability.
* Employees and leadership committed to learning (option C) is a proven characteristic of high performance.
* Other options-individualism, mandated training, and disincentivized development-are actually barriers to DevOps success.
Extract-style reference:
"High-performing organizations deliberately invest in learning and development and have leaders who model and reward learning behaviors."
-Accelerate: The Science of Lean Software and DevOps, Nicole Forsgren et al.
PeopleCert DevOps Foundation v3.6: The syllabus highlights that a "culture of learning" and psychological safety are core characteristics of successful DevOps organizations.
NEW QUESTION # 23
An organization has identified they have a culture of blame where people are fearful of failure and lack the courage to try new things.
What can they do to encourage more courageous and experimentational behaviors?
- A. Build rituals that reward risk taking
- B. Both b and c
- C. Sharing is inhibited
- D. Identify and punish the people that make mistakes
Answer: A
Explanation:
Ablame cultureis toxic and inhibits innovation. DevOps encourages a culture where risk-taking and experimentation are rewarded, not punished.
Organizations should "build rituals that reward risk taking"-examples include celebrating "fast failures" and running blameless post-mortems.
Extract-style reference:
"Encourage a culture where failure is seen as a learning opportunity, not a cause for punishment. Rituals that reward risk-taking foster innovation and create psychological safety."
-DevOps Handbook
DevOps Foundation v3.6 (Cultural Principles section) advocates psychological safety, learning from failure, and reward systems that incentivize experimentation.
NEW QUESTION # 24
What are the CORRECT set of DevOps values?
- A. Culture, Collaboration, Communication, Commitment
- B. Culture, Automation, Lean, Measurement, Sharing
- C. Culture, Accountability, Lean, Metrics, Sharing
- D. Culture, Automation, Lean, Metrics, Sharing
Answer: B
Explanation:
According to PeopleCert DevOps Foundation v3.6, the five primary values that guide successful DevOps adoption are summarized in theCALMSframework:Culture, Automation, Lean, Measurement, and Sharing.
* Culturefocuses on breaking down silos, encouraging trust, and promoting collaboration between development, operations, security, QA, and business teams.
* Automationis essential for speeding up delivery, reducing manual errors, and ensuring repeatability across the software delivery lifecycle.
* Leanemphasizes the elimination of waste, limiting work in progress (WIP), and improving flow.
* Measurementmeans using metrics and data to inform decisions, identify bottlenecks, and drive continuous improvement.
* Sharingfosters transparency, knowledge transfer, and a unified approach to goals and problem-solving.
Option A replaces automation and lean principles with softer collaboration aspects, which are important but not recognized as the formal value set. Option C replaces "Measurement" with "Metrics," which is only a part of measurement. Option D substitutes "Accountability" for "Automation," which is not part of the CALMS model.
Therefore, the official correct set of values per the DevOps Foundation syllabus isB.

NEW QUESTION # 25
Which of the following are benefits of automation?
- A. Higher quality and faster recovery
- B. Fewer errors and slower lead time
- C. More frequent and turbulent releases
- D. Decreased security and risk mitigation
Answer: A
Explanation:
Automationbrings multiple key benefits in DevOps:
* Higher quality:Automated tests and deployments catch errors earlier, reduce human error, and ensure consistency.
* Faster recovery:Automated monitoring and remediation help restore services quickly after incidents.
* Other options either decrease quality, increase errors, or make releases less predictable-contradicting DevOps goals.
Extract-style reference:
"Automation reduces errors, increases quality, accelerates lead time, and shortens recovery by ensuring repeatable, reliable processes."

NEW QUESTION # 26
What is one of the PRIMARY benefits of Continuous Delivery?
- A. It prioritizes working on new features over keeping software deployable
- B. It reduces the cost, time, and risk of delivering incremental changes to the business
- C. It ensures that all releases are deployed into production in a timely manner
- D. It automates all of the tasks associated with development and operations
Answer: B
Explanation:
Continuous Delivery's primary benefit is that itreduces the cost, time, and risk of delivering incremental changes. By keeping software deployable at all times, teams can ship small, low-risk releases as needed.
* A:Prioritizing features over deployability increases risk.
* B:Not all releases are deployed immediately; CD keeps themready.
* D:CD doesn't automate everything-some manual steps may remain, especially in Continuous Delivery (vs. Continuous Deployment).
Extract-style reference:
"Continuous Delivery reduces deployment pain by ensuring that code is always in a deployable state, decreasing the cost, time, and risk associated with releases."

NEW QUESTION # 27
The IT department of a very large insurance company is trying to improve the collaboration and communication between development and operational teams without much success. The department has many silos that are organized by expertise and led by a different manager. The managers of each team do not seem to be particularly interested in DevOps since they have been operating this way for many years and like their silo culture.
What is this organization suffering from?
- A. Low trust
- B. Organizational change
- C. Change fatigue
- D. Cultural debt
Answer: D
Explanation:
The scenario describes entrenched silos and resistance to change-managers are protective of their domains and don't see the value of DevOps.
* This is a textbook example ofcultural debt: the gap between the organization's current culture and the adaptive, collaborative culture needed for DevOps success.
* Cultural debt, like technical debt, accumulates over time and "must be paid back" for transformation to succeed. It creates friction, slows delivery, and blocks cross-team collaboration.
Why not the others?
* Organizational changeis what's needed, not what they're suffering from.
* Change fatiguearises when people are burned out bytoo muchchange, not resistance.
* Low trustis a symptom, but the core problem here is ingrained culture.
Reference/Extract:
"Cultural debt is accrued when organizations fail to evolve their culture to match new ways of working, like DevOps. It manifests in resistance to collaboration, entrenched silos, and leadership unwilling to change."

NEW QUESTION # 28
Which of the following metrics relates to The Third Way?
- A. Change fail rate
- B. Change cycle times
- C. Change lead times
- D. Hypothesis or experiments log
Answer: D
Explanation:
TheThird Wayin DevOps emphasizescontinuous learning and experimentation. It's about fostering a culture where teams test hypotheses, take calculated risks, and learn from both successes and failures.
Ahypothesis or experiments logdirectly supports this principle by capturing:
* The changes or experiments attempted
* The hypothesis behind them
* The results and insights gained
Metrics likeA,B, andCare more aligned with theFirst Way(flow) andSecond Way(feedback). They measure speed and stability but not the experimental learning process itself.
By tracking experiments, organizations can make data-driven decisions, reinforce a learning culture, and continuously refine practices-core aspects of the Third Way.

NEW QUESTION # 29
A large organization conducts a DevOps toolchain review and discovers that multiple development teams have built their own continuous delivery pipelines with a variety of different tooling.
Which of the following strategies would NOT help them manage their toolchain evolution moving forwards?
- A. Having IT Operations or infrastructure squads architect and manage a DevOps toolchain service to offer to the development teams
- B. Telling all development teams they must immediately migrate to a standard set of tools dictated by IT Operations
- C. Making the DevOps toolchain available self-service
- D. Using sensible defaults to guide teams' choices
Answer: B
Explanation:
Forcing all development teams toimmediately migrateto a standard set of tools dictated by IT Operations is nota recommended DevOps strategy.
* DevOps promotescollaboration, flexibility, and evolutionof toolchains, allowing teams to choose what fits their needs while moving toward sensible defaults and integration over time.
* Abrupt, top-down mandates undermine trust and autonomy, often leading to resistance and lower adoption.
Why are the other options better?
* IT Ops or infra squads managing toolchain as a service(A),sensible defaults(C), andself-service(D) are all recognized best practices to support DevOps evolution and developer enablement.
Extract-style reference:
"Mandating a single toolset without considering team needs reduces engagement. Toolchains should be managed as self-service platforms with sensible defaults, supporting but not constraining teams."

NEW QUESTION # 30
How do you define Wait Time?
- A. Lead time minus cycle time
- B. Lead time plus cycle time
- C. Cycle time minus lead time
- D. Cycle time multiplied by lead time
Answer: A
Explanation:
Wait Timeis the time work spends waiting between process steps-wasted, non-value-added time.
* Mathematically,Wait Time = Lead Time - Cycle Time
* Lead Time:Time from work request to delivery.
* Cycle Time:Time spent actively working on the item.
Why is this important in DevOps?
Identifying and reducing wait time (waste) is central to Lean/DevOps, directly improving flow and reducing delays.
Extract-style reference:
"Wait time is calculated as the difference between lead time and cycle time-highlighting bottlenecks in the value stream."
-DevOps Handbook
PeopleCert DevOps Foundation v3.6:Wait time is a core Lean concept for optimizing flow.
NEW QUESTION # 31
Which of the following is NOT a characteristic of a DevOps culture?
- A. Command and control
- B. Reflective
- C. Data driven
- D. Accountability
Answer: A
Explanation:
ADevOps cultureis built on principles like being data-driven, reflective (willing to learn from experience), and accountable (taking ownership, not blaming others).
* Command and controlcultures are the opposite: hierarchical, rigid, discouraging initiative and learning. DevOps strives for empowerment, experimentation, and psychological safety.
Why not the others?
* Data-driven:Decisions are based on measurement and feedback, core to DevOps.
* Reflective:Regular retrospectives and post-incident reviews are essential DevOps rituals.
* Accountability:Teams are responsible for the software they build and operate.
Reference/Extract:
"DevOps culture values collaboration, continuous learning, and a data-driven, accountable approach to improvement. Command and control structures stifle innovation and slow down feedback."
-State of DevOps Report(2019), PeopleCert DevOps Foundation v3.6 Section 3.2
NEW QUESTION # 32
An organization has had a series of recent failures in one of their core applications. The time it took to identify and resolve the error exceeded agreed service levels. The IT service provider is trying to identify ways to improve their ability to recover while also improving their resiliency. Which of the following principles behind the Third Way could help their situation?
- A. They could analyze their internal processes to identify constraints that are affecting workflow and delays
- B. They could review their MTTR statistics to see where they could add more redundant systems
- C. They could intentionally inject faults into their infrastructure to practice their ability to recover and identify ways to increase their resiliency
- D. They could provide more opportunities for feedback from DevOps stakeholders
Answer: C
Explanation:
TheThird Wayin DevOps emphasizescontinual learning and experimentation. One of the most effective resilience-building practices in this category ischaos engineeringor deliberate fault injection. This involves introducing controlled failures into systems-such as shutting down services, simulating network latency, or exhausting resources-totest the organization's recovery capabilityin realistic scenarios.
By practicing recovery under controlled conditions, teams identify weaknesses in monitoring, automation, documentation, and communication before a real incident occurs. This improvesMean Time to Recovery (MTTR)and overall system resilience.
OptionA(constraint analysis) relates to theFirst Way(flow optimization). OptionCfocuses on feedback loops ( Second Way). OptionD(adding redundancy) is a possible improvement but does not inherently practice and improve operational recovery skills in the same way as deliberate fault injection.
Therefore,Bis the most appropriate Third Way principle for improving resilience in this scenario.
