What is the recommended way to prioritize the potential items for the DevOps transformation? Minimum marketable feature Lean business case Minimum viable product Weighted Shortest Job First Weighted shortest job first is applied to backlogs to identify what? Epics, Features, and Capabilities Proxy for job size Maximum economic value User business value Which steps in the Value Stream should be the main focus when prioritizing improvement items? Steps with long lead time and short process time in the current-state map Steps with a long process time Steps with short process time and short lead time in the future-state map Steps with a high activity ratio What are two parts of the Continuous Delivery Pipeline? (Choose two.) Continuous Testing Deploy on Demand Continuous Delivery Continuous Deployment Continuous Integration What marks the beginning of the Continuous Delivery Pipeline? A checked-in change A committed Feature A committed user story An idea What are two benefits of DevOps? (Choose two.)You have reached the max number of allowed answers Faster lead time Increased batch size Fewer defects Tightly coupled architecture Better alignment between strategy and execution Where do features go after Continuous Exploration? Into the Program Backlog where they are then prioritized Into Continuous Integration where they are merged and tested with other Features Into development where they are then split into Stories Into a backlog tool where they are then split into Epics Ensuring that security controls such as threat modeling, application security, and penetration testing are in place throughout the Continuous Delivery Pipeline is an example of which stabilizing skill? DevSecOps Continuous security monitoring Failover/disaster recovery Design for operations Which two statements describe the purpose of value stream mapping? (Choose two.)You have reached the max number of allowed answers To create an action plan for continuous improvement To visualize how value flows To understand the Product Owner’s priorities To create an understanding of the budget To deliver incremental value in the form of working, tested software and systems How is Lean UX used in Continuous Exploration? To validate the return on investment To collaboratively create a benefit hypothesis To create a platform to continuously explore To automate the user interface scripts When should teams use root cause analysis to address impediments to continuous delivery? During Iteration Planning During the Iteration Retrospective During the management review & problem solving portion of PI Planning During Inspect and Adapt The Continuous Exploration aspect primarily supports which key stakeholder objective? Business value Research and development Alignment Hypothesize What triggers the Release activity? Business decision to go live Successful user acceptance tests Change validated in staging environment Successful deployment to production Feature toggles are useful for which activity? To enable continuous code integration To decouple deployment from release To enable continuous testing To prevent testing complexity Which teams should coordinate when responding to production issues? SRE teams and System Teams Teams across the Value Stream Support teams and Dev teams Dev teams and Ops teams What organizational anti-pattern does DevOps help to address? Organizations that make decisions along functional lines Teams that are isolated and working within functional areas (e.g., business, operations, and technology) Organizations that have at least three management layers Too much focus on centralized planning When does the Continuous Integration aspect of the Continuous Delivery Pipeline begin? When the Team Backlog has been refined When a user story has satisfied its definition of done When a Feature has been pulled for work When code is checked-in to version control What is an output of the Release activity? A Feature migrated to the cloud A Feature deployed to production A Feature made available to end users A Feature made available to internal users What is a consequence of working in isolation on long-lived code branches? Deployments will fail Trunk/main will not always be in a deployable state Rollbacks will be difficult Static analysis tests will fail Gemba walks are an important competency in support of which activity of the DevOps Health Radar? Hypothesize Learn Verify Collaborate and Research The DevOps Health Radar aligns the four aspects of the Continuous Delivery Pipeline to which four stakeholder concerns? Alignment, quality, time-to-market, business value Exploration, integration, development, reflection Productivity, efficiency, speed-to-market, competitive advantage Portfolio, Solution, program, team What can impede the progress of a DevOps transformation the most? When teams use frequent retrospectives When there is no DevOps team When various groups in the organization have different directions and goals Lack of funding for CI/CD pipeline tools What should be measured in a CALMR approach to DevOps? Measure everything Deployment frequency Unit test coverage Mean time to restore What does the activity ratio measure in the Value Stream? The percentage of time spent on manual activities The percentage of time spent on non-value-added activities The percentage of time spent on value-added activities The percentage of time spent on delays to the number of processes in the Value Stream What identifies potential changes to the current-state Value Stream that could improve flow? Impact mapping Value Stream identification Problem-solving workshop Future-state mapping Which technical practice incorporates build-time identification of security vulnerabilities in the code? Threat modeling Penetration testing Dynamic code analysis Application security Scanning application code for security vulnerabilities is an important step in which aspect of the Continuous Delivery Pipeline? Release on Demand Continuous Deployment Continuous Exploration Continuous Integration Which two skills appear under the Respond activity? (Choose two.) Service virtualization Telemetry Cross-team collaboration Version control Automatic rollback Which Metric reflects the quality of output at each step in the Value Stream? Escaped defects Deployment frequency Percent complete and accurate (%C/A) Process time What are two reasons for test data management? (Choose two.)You have reached the max number of allowed answers To track the results of automated test cases for use by corporate audit To truncate data from the database to enable fast-forward recovery To generate synthetic test data inputs in order to validate test scenarios for automated tests maintained in version control To automate provisioning data to an application in order to set it to a known state before testing begins To provide a viable option for disaster-recovery management What work is performed in the Build activity of the Continuous Delivery Pipeline? Code Compile Automated acceptance testing Code review What should the team be able to do after current-state mapping? Define a plan to reduce the lead time and increase process time Describe the biggest bottlenecks in the delivery pipeline Identify those responsible for the biggest bottlenecks in the process Understand the steps needed to improve the Continuous Delivery Pipeline Which statement illustrates the biggest bottleneck? LT = 1 day, PT = 0.5 day, %C&A = 90% LT = 10 days, PT = 0.5 day, %C&A = 100% LT = 5 days, PT = 2.5 days, %C&A = 100% LT = 6 days, PT = 5 days, %C&A = 100% When full deployment automation is not possible, which practice helps developers deploy code into production? Infrastructure as code Deployment automation Continuous Deployment Self-service deployment A canary release involves releasing value to whom? Internal users only One subset of users at a time External users only Internal users first What does value stream mapping help reveal in the Continuous Delivery Pipeline? Who is responsible for optimizing the Value Stream Bottlenecks to the flow of value Where automation is needed Where documentation should be reduced Continuous Deployment enables which key business objective? Release continuously Business value Manage technical debt Time-to-market What is one potential outcome of the Verify activity of the Continuous Delivery Pipeline? Analyze regression testing results Analyze end user behavior and Feature adoption Metrics Roll back a failed deployment Fix a broken build Why is hypothesis evaluation important when analyzing data from monitoring systems in the Release on Demand aspect? It helps quickly create balanced scorecards for stakeholder review It helps identify the minimum viable product for evaluating the hypothesis It helps operations teams know where to apply emergency fixes It helps link objective production data to the hypothesis being tested What are the top two advantages of mapping the current state of the delivery pipeline? (Choose two.) To achieve a collective understanding and consensus around problems To enable everyone in the organization to see how the Value Stream is actually performing To help identify and make short-term fixes To help with incremental software delivery To identify some of the processes within the delivery pipeline Which statement describes what could happen when development and operations do not collaborate early in the pipeline? Surprises are found in deployment that lead to significant rework and delay Lead times are reduced Teams build things quickly but build the wrong things Automation of integration test is not possible What differentiates Deployment and Release in the Continuous Delivery Pipeline? Deployment is performed by development; release is performed by operations Deployment is done on a cadence; release is done on demand Deployment involves moving value to production; release involves making value available to end users Deployment occurs every Iteration; release occurs at PI boundaries What is true about the Boundaries and Limitations portion of the DevOps Transformation Canvas? It captures budget constraints that will prevent DevOps improvements It captures the people who need to be involved in the DevOps transformation It captures improvement items that require the support of other people or teams It captures the lowest priority improvement items What are the first two areas that should be identified in value stream mapping? (Choose two.) The people who do the work The steps Process time, lead time, and percent complete and accurate The bottlenecks The people who supervise the work How should developers integrate refactoring into their workflow? Create and estimate refactoring Stories in the Team Backlog Refactor continuously as part of test-driven development Create and estimate refactoring tasks for each Story in the Team Backlog Allocate a portion of their capacity to refactoring in every Iteration
