SAFE DevOps Exam Questions With All
Correct & Verified Answers
Lead Time (LT) Correct answer-Part of Activity Ratio. Time from when work was ready after the
previous station to completion
Process Time (PT) Correct answer-Part of Activity Ratio. Time to complete actual value-added work
Percent Complete and Accurate (%C&A) Correct answer-Percent of work that the next station
could process as-is
Activity Ratio Correct answer-Measures activity efficiency (PT/LT)
Rolled Percent Complete & Accurate Correct answer-Measures efficiency of entire flow (%C&A 1 *
%C&A 2 * %C&A n * 100)
Current State of Delivery Pipeline Correct answer-Visualized by laying out: Steps - Roles - Measure
Steps - Calculate Total Metrics
Continuous Exploration Correct answer-Section of Continuous Delivery Pipeline whose business
objective = Alignment and is broken down into the following domains: Hypothesize, Collaborate &
Research, Architect, Synthesize
Hypothesize Correct answer-Define the hypothesis to be validated through the Continuous
Delivery Pipeline; Skills = Lean Startup, Innovation Accounting
Lean Startup Correct answer-Focuses on identifying the viability of ideas following PDCA; includes
using MVP to establish baseline to test assumptions and gather objective data; if the MVP proves
out, the value stream will continue to develop features. If not, pivot. Uses Innovation Accounting.
Innovation Accounting Correct answer-Part of the Lean Startup Cycle. Validates learning and
reduces waste through fast feedback loops. It has 3 learning milestones: Minimum Viable Product
(MVP), Tune the Engine, and Pivot. Focuses on Leading Indicators and avoids Vanity Metrics.
Continuous Integration Correct answer-Section of Continuous Delivery Pipeline whose business
objective = Quality and is broken down into the following domains: Develop, Build, Test end-to-end,
and Stage
Builds quality into the development process by integrating ongoing work of Agile Teams. All work is
version controlled, and new functionality is built and continuously integrated into a full system or
solution and tested end-to-end before being validated on a staging environment.
Continuous Delivery Pipeline Correct answer-Represents workflows, activities, and automation
needed to support functionality from ideation to value to the end user.
Program Kanban Correct answer-Tool
Helps ensure that features are analyzed prior to reaching an iteration boundary. They are estimated
and prioritized appropriately, and feature acceptance criteria are established
, Scrum of Scrums Correct answer-Ceremony
- Visibility into progress and impediments
- Facilitated by RTE
- Participants: Scrum Masters, others as necessary
- Weekly or more frequently
- Timebixed and followed by a "Meet After"
PO Sync Correct answer-Ceremony
- Visibility into progress, scope, and priority adjustments
- Facilitated by RTE or PM
- Participants: PMs, POs, others as necessary
- Weekly or more frequently
- Timeboxed a d followed by a "Meet After"
ART Sync Correct answer-Ceremony
The combination of SoS and PO Sync
DevOps Correct answer-Approach to bridge the gap between development and operations to
deliver faster and more reliably.
- Is in the Value Stream
- Only occurs when end users are operating the solution
- Isn't optional; only question is how effective it is
Release on Demand Correct answer-Section of Continuous Delivery Pipeline whose business
objective = Value and is broken down into the following domains: Release, Stabilize, Measure, and
Learn
The process by which features deployed into production are released incrementally or immediately
to Customers based on market demand.
CALMR approach to DevOps Correct answer-- Culture: Establish and culture of shared
responsibility for development, deployment and operations
- Automation: Automate the Continuous Delivery Pipeline
- Lean flow: Keep batch size small, limit WIP, and provide extreme visibility
- Measurement: Measure the flow through the pipeline. Implement application telemetry
- Recovery: Architect and enable low-risk releases. Establish fast recovery, fast reversion, and fast fix-
forward.
**IMPLEMENTED IN REVERSE
Benefit Hypothesis Correct answer-Justifies feature implementation cost and provides business
perspective when making scope decisions
Feature Correct answer-Object
- Component of an Epic
- Has a Benefit Hypothesis
