Free PeopleCert DevOps-Foundation Practice Exam with Questions & Answers

TheSite Reliability Engineer (SRE)role originated at Google and is now widely recognized. SREs apply software engineering principles to IT operations to create systems that arescalable, reliable, and highly available. Their responsibilities include:

Designing reliability into systems (SLIs, SLOs, SLAs)

Automating operational tasks to reduce toil

Building monitoring and alerting systems

Performing capacity planning and disaster recovery exercises

A(Site resilience engineer) is not a standard industry term.C(Software engineer) focuses on developing applications but not specifically on operational reliability.D(Product Owner) is a role in Agile frameworks that manages product backlog and priorities, not system reliability.

Thus, the correct answer isB – Site Reliability Engineer.

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.

A DevOps professional needs:

Business skills: Understanding the business context and value.

Technical skills: Automation, coding, cloud, infrastructure.

Core (soft) skills: Collaboration, communication, empathy, learning.

Self-management: Time, priorities, feedback.

Other options miss the full blend or focus too much on tech or process.

Extract-style reference:

“DevOps success requires a blend of business, technical, and core (soft) skills, as well as the ability to self-manage and continuously learn.”

PeopleCert DevOps Foundation v3.6: Holistic skillsets are emphasized for cross-functional teams.

When teams have experienced frequent top-down mandates without adequate involvement, they may feel change fatigue and resist new initiatives. PeopleCert DevOps Foundation v3.6 emphasizes the importance ofengagement and empowermentto build buy-in and ownership for DevOps transformation.

Empowering people means involving them in decisions, encouraging contribution of their ideas, and making them active participants in shaping the DevOps adoption plan. This approach builds trust, reduces resistance, and taps into collective knowledge, leading to solutions that are practical and widely accepted.

OptionsA,B, andCcan support DevOps adoption but do not address the root cause of low enthusiasm—lack of involvement. Empowerment fosters intrinsic motivation, which is essential for sustained cultural change.

Thus,Dis the most effective choice.

When developers practice agile but operations is slow to deploy, it means IT Operations have not kept pace—classic “left behind” scenario. DevOps aims to align development and operations, breaking down barriers and enabling faster, safer, and more frequent deployments. DevOps is not only about development (B is incorrect), does not break cadence but instead aligns it (C is incorrect), and is not the same as agile but complements it (D is incorrect).

Change fatigue occurs when employees experience too many changes without clear purpose or connection to business value. The most effective way to reduce resistance is to ensure that DevOps adoption isaligned with strategic business goalsand clearly demonstrates how it supports organizational priorities.

When teams see thedirect business impactof their work—such as improved customer experience, faster delivery of products, or increased competitiveness—they are more likely to embrace change.

OptionsA,B, andCmay have short-term benefits but do not address the underlying need for strategic alignment and purpose.

Thus,Dis the most effective way to minimize change fatigue during DevOps introduction.

Both B and C (Application of agile and lean methods + Management commitment to culture change)are critical success factors when launching DevOps in a traditional IT organization.

Agile/Lean methods: Accelerate delivery, reduce waste, create feedback.

Management commitment to culture change: Essential for breaking silos, changing behaviors, and making DevOps sustainable.

Forming a pilot team (A)helps, but isn’t sufficient without these foundations.

Extract-style reference:

“DevOps success starts with leadership commitment to cultural change and adopting Agile and Lean principles throughout the organization.”

—DevOps Handbook,State of DevOps Report

PeopleCert DevOps Foundation v3.6:Lists cultural commitment and Lean/Agile as prerequisites for DevOps transformation.

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.”

—DevOps Handbook

PeopleCert DevOps Foundation v3.6:Automation is a pillar of DevOps, referenced throughout the syllabus as a key driver for speed and reliability.

Deployment frequencyis not aculture metric.

It’s aprocessmetric, indicating how often code is released.

Culture metricsfocus on engagement, morale, retention, psychological safety, and NPS.

Why not the others?

Employee NPS:Measures employee satisfaction and willingness to recommend.

Engagement/morale:Direct indicators of cultural health.

Retention:How well an org keeps talented people, reflecting culture.

Extract-style reference:

“Measuring DevOps culture relies on employee engagement, morale, and retention, not on delivery metrics like deployment frequency.”

—State of DevOps Report

PeopleCert DevOps Foundation v3.6:Culture metrics focus on people, not just process.

Lean tools and practicesare foundational to DevOps because they help organizations systematically identify and eliminate waste, optimize value delivery, and continuously improve processes.

Lean thinkingfocuses on value stream mapping, reducing delays, bottlenecks, over-processing, handoffs, rework, and unnecessary tasks—core to making DevOps successful.

Option D, “They help identify waste and assist in the creation of improvement practices,” perfectly captures this focus.

Extract-style reference:

“Lean enables teams to identify value and non-value-added activities and to use continuous improvement techniques such as Kaizen, value stream mapping, and removing waste.”

—DevOps Handbook

PeopleCert DevOps Foundation v3.6: Lean tools like Value Stream Mapping, 5S, and Kaizen are cited as critical enablers for optimizing the flow and improving IT and business alignment.
