DevOps-Foundation Exam Dumps and Practice Questions

Epics delivered is a software/process metric, not a business performance metric.

Business performance metrics include financial and market indicators: earnings, cashflow, market share, revenue growth.

Why not the others?

Earnings, Cashflow, Marketshare: Directly tied to business health.

Extract-style reference: ''Business performance metrics focus on outcomes such as earnings, cashflow, and marketshare. Agile metrics like epics delivered measure team output, not business value.'' --- Project to Product, Mik Kersten PeopleCert DevOps Foundation v3.6: Distinguishes business impact from process metrics.

The two best measures to show shared success across technology teams are throughput and stability:

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 on both ensures teams deliver quickly and safely. 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.'' --- Accelerate: The Science of Lean Software and DevOps, Ch. 2 PeopleCert DevOps Foundation v3.6: Shared success is about flow and reliability, not just one or the other.

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.

The Deming Cycle (Plan-Do-Check-Act) is foundational to continuous improvement in Lean, and is specifically applied in the Improvement Kata practice:

Improvement Kata: A structured routine for continuous, incremental improvement based on scientific thinking (PDCA).

Value Stream Mapping and Andon cord are Lean practices, but they don't directly reference PDCA as the core mechanism.

Extract-style reference: ''The Improvement Kata incorporates the Deming cycle (Plan-Do-Check-Act) to drive small, rapid cycles of change, helping teams to experiment, learn, and adjust.'' --- Toyota Kata, Mike Rother PeopleCert DevOps Foundation v3.6: Cites PDCA as integral to continuous improvement and Lean/DevOps adoption.

The ''Three Ways'' are foundational principles in DevOps:

The First Way focuses on increasing the flow of work from left (development) to right (operations). It is about optimizing the entire system for fast delivery, limiting bottlenecks, and enabling a rapid flow of features and fixes to customers.

The Second Way is about amplifying feedback loops so corrections can be made early.

The Third Way emphasizes continual learning and experimentation.

Extract-style reference: ''The First Way emphasizes the performance of the entire system, as opposed to the performance of a specific silo of work or department. The goal is to maximize the flow of work (value) from Development to Operations to the customer.'' --- Gene Kim, The Phoenix Project / DevOps Handbook PeopleCert DevOps Foundation v3.6 highlights this in the section on 'Principles and Practices,' emphasizing The First Way as critical to accelerating flow.
