DevOps-Foundation Exam Dumps - PeopleCert DevOps Questions and Answers

Forcing all development teams toimmediately migrateto a standard set of tools dictated by IT Operations isnota 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.”

—State of DevOps Report;DevOps Handbook

PeopleCert DevOps Foundation v3.6:Encourages enabling choice, not enforcing uniformity without context.

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.

The two best measures to showshared successacross technology teams arethroughputandstability:

Throughput(deployment frequency, lead time): Measures how fast teams deliver value.

Stability(change failure rate, MTTR): Measures how reliably systems operate.

Why these two?

Focusing onbothensures teams deliver quicklyandsafely. High throughput without stability causes outages; stability without throughput slows business.

Other options:

Deployment frequency + change lead/cycle time: Both are throughput measures, missing stability.

MTTR + change failure rate: Both are stability, missing throughput.

Employee retention and NPS: People measures, not delivery.

Extract-style reference:

“High performers in DevOps exhibit both high throughput (deployments per day) and high stability (low failure rates, fast recovery), proving it’s possible to achieve both.”

PeopleCert DevOps Foundation v3.6:Shared success is about flowandreliability, not just one or the other.

Cycle Timein Agile and DevOps measures the time taken for work to move from thestart of active work (“in progress”) to completion (“done”). It reflects the efficiency of the development process and helps identify bottlenecks in active work.

BandCdescribeLead Time, which includes the time spent in the backlog before work starts.Dis a subset metric related to build/test time, not the full cycle time.

Shorter cycle times indicate more efficient processes and faster delivery of value. Monitoring cycle time enables continuous improvement by highlighting delays within active work.

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.

Successful DevOps transformation hinges onmanagement commitment to cultural change. This includes leadership support for breaking down silos, encouraging collaboration, fostering psychological safety, and aligning incentives.

While budget, reorganization, and deployment pipelines are important enablers, they cannot deliver sustainable transformation without cultural alignment. Leaders must model desired behaviors, remove systemic blockers, and reinforce the new ways of working.

Without cultural change, DevOps becomes a tooling initiative rather than a true organizational shift.

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.

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.

The most effective approach to tool selection in DevOps is to establish a toolchain—a set of integrated tools that support the end-to-end lifecycle (planning, coding, building, testing, releasing, deploying, operating, and monitoring).

This encourages consistency, automation, and traceability, while still allowing flexibility for teams.

Why not standardize on one vendor?

This reduces flexibility, can cause vendor lock-in, and doesn’t support the varied needs of Dev and Ops teams.

Encouraging independent selection (C) increases fragmentation.

Focusing solely on testing (D) ignores the broader lifecycle.

Extract-style reference:

“Establishing an integrated toolchain provides end-to-end visibility and automation across the software delivery pipeline, aligning tools with process and cultural change.”

— State of DevOps Report; DevOps Handbook

PeopleCert DevOps Foundation v3.6: Recommends a toolchain approach for supporting collaborative DevOps practices.

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.
