Question 1

How do you define Wait Time?

ALead time minus cycle time

BCycle time minus lead time

CLead time plus cycle time

DCycle time multiplied by lead time

Answer : A

Wait Time is 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.

Question 2

What is the BEST description of the Theory of Constraints?

AA methodology for identifying the most important limiting factor that stands in the way of achieving a goal

BA methodology for shortening feedback loops so that IT is able to understand and respond faster to customer needs

CA methodology for encouraging experimentation and learning so that organizations can identify constraints and practice for failure

DA methodology for designing and implementing the processes that underpin deployment pipelines

Answer : A

Theory of Constraints is a methodology that seeks to identify the single, most important limiting factor (constraint) in a process and systematically improve it until it's no longer the limiting factor.

Extract-style reference: ''The Theory of Constraints provides a powerful framework for identifying bottlenecks (constraints) that limit system performance and focusing improvement efforts on these areas to maximize throughput.'' --- Goldratt's Theory of Constraints DevOps Foundation syllabus discusses this as a foundational Lean concept, directly applicable to software delivery pipelines, where delays or resource shortages can restrict overall throughput.

Question 3

Which of the following DevOps practices encourages conversation driven development, delivery and support?

AThe Second Way

BChatOps

CCommunication Platforms

DVisOps

Answer : B

ChatOps is the DevOps practice of using chat platforms (like Slack, Teams, Mattermost) as the central interface for communication, collaboration, and even automated deployment or support tasks. It encourages ''conversation-driven development, delivery, and support,'' making processes transparent and collaborative.

Second Way (A) is about feedback loops, but not specifically conversational platforms.

Communication Platforms (C) is a generic term.

VisOps (D) is not a standard DevOps term.

Extract-style reference: ''ChatOps is a collaboration model that connects people, tools, process, and automation into a transparent workflow. Teams communicate and execute commands from a central chat client.'' --- DevOps Handbook PeopleCert Foundation v3.6: ChatOps promotes rapid feedback and a culture of sharing.

Question 4

According to the State of DevOps Reports, LOW performing organizations have:

AMore frequent code deployments

BFaster lead times from commit to deploy

CFaster mean times to recovery

DHigher change failure rates

Answer : D

The State of DevOps Reports show that LOW performing organizations have higher change failure rates, meaning a larger percentage of changes lead to incidents, outages, or degraded service. In contrast, high performers have more frequent deployments, faster lead times, and quicker recovery from incidents. Reference: DevOps Foundation v3.6 syllabus section 2.2; Accelerate: The Science of Lean Software and DevOps.

Question 5

Agile funding can be______

AFixed cost

BContinuous cost

CReviewed frequently

DAll of the Above

Answer : D

Agile funding is flexible and adapts to the iterative, incremental nature of Agile and DevOps projects.

It can be fixed cost for some work, continuous cost for ongoing value streams, and is reviewed frequently to align with evolving priorities.

All three characteristics are true, so D (''All of the Above'') is correct.

Extract-style reference:

''Agile funding models support continuous review and adaptation, providing the flexibility required for digital transformation and DevOps ways of working.''

--- Project to Product, Mik Kersten

PeopleCert DevOps Foundation v3.6: Advocates funding models that encourage agility, experimentation, and rapid value delivery.

Question 6

Which of the following MOST accurately describes DevOps?

AA team

BA methodology

CA standard

DA cultural and professional movement

Answer : D

DevOps is not simply a team, methodology, or standard. The PeopleCert DevOps Foundation v3.6 materials define DevOps as a ''cultural and professional movement'' that stresses communication, collaboration, integration, and automation to improve workflow between software developers and IT operations professionals. The cultural transformation is fundamental, emphasizing shared responsibilities, breaking down silos, and fostering continuous improvement. Reference: DevOps Foundation v3.6 syllabus section 1.1; State of DevOps Report; 'The Phoenix Project'.

Question 7

Which of the following is NOT a crucial ingredient when leading a digital transformation?

ACollaboration

BCommand

CCuriosity

DCourage

Answer : B

Command (authoritarianism) is not a crucial ingredient for leading digital transformation. The key ingredients:

Collaboration

Curiosity

Courage

DevOps leadership is about empowering teams, experimenting, and driving change, not command-and-control.

Extract-style reference: ''Digital transformation leaders embrace collaboration, curiosity, and courage, fostering an environment where experimentation and learning drive change.'' --- Accelerate, DevOps Handbook PeopleCert DevOps Foundation v3.6: Advocates servant and transformational leadership, not command/control.
