ChatOpsis the practice of conducting operational work directly through chat platforms (e.g., Slack, Microsoft Teams) integrated with automation and tooling. In this case:

Teams from multiple locations are collaborating in real-time via Slack.

They are running commands and queries directly from the chat to the delivery and monitoring systems.

This allows shared visibility, immediate context, and rapid action during incident resolution.

WhileA(Swarming) describes a collaborative incident response, it does not specifically imply integration with chat-based tools.C(Incident Management) is the overall process, andD(IT Support) is a function, but neither capture the specific ChatOps approach.

Thus,B – ChatOpsis the most accurate answer here.

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.

Epics deliveredis asoftware/process metric, not a business performance metric.

Business performance metricsinclude 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.

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.

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.
