How should developers integrate refactoring into their workflow? Allocate a portion of their capacity to refactoring in every Iteration Create and estimate refactoring tasks for each story in the te ... am backlog Create and estimate refactoring stories in the team backlog Refactor continuously as part of Test-Driven Development What is one potential outcome of the Verify sub-dimension of the pipeline? Analyze end user behavior and feature adoption metrics Roll back a failed deployment Fix a broken build Analyze regression testing results The Explore dimension primarily supports which key stakeholder objective? Business Value Research and Development Alignment Hypothesize Which activity is performed in the Build sub-dimension of the pipeline? Code Compile Code review Automated acceptance testing Which statement describes what could happen when Development and Operations do not collaborate early in the pipeline? Lead times are reduced Automation of integration test is not possible Teams build things quickly but build the wrong things Surprises are found in deployment that lead to significant rework and delay Which two skills appear under the Respond sub-dimension? (Choose two.)You have reached the max number of allowed answers Telemetry Cross-team collaboration Version control Automatic rollback Service virtualization The DevOps Radar aligns the dimensions to which four stakeholder concerns? Productivity, efficiency, speed-to-market, competitive advantage Alignment, quality, time-to-market, business value Portfolio, solution, program, team Exploration, integration, development, reflection What are two parts of the Continuous Delivery Pipeline? (Choose two.) Continuous Delivery Continuous Integration Deploy on Demand Continuous Exploration Continuous Testing What does the Activity Ratio measure in the value stream? The percentage of time spent on value-added activities The efficiency of the business process activities as a ratio of process time to cycle time The percentage of time spent on delays to the number of processes in the value stream The percentage of time spent on non-value-added activities What is an output of the Release sub-dimension? A Feature deployed to production A Feature made available to internal users A Feature made available to end users A Feature migrated to the cloud Gemba walks are an important competency in support of which sub-dimension of the DevOps Health Radar? Collaborate and Research Hypothesize Learn Verify Why is hypothesis evaluation important when analyzing data from monitoring systems in the Release dimension? It helps Operations teams know where to apply emergency fixes It helps quickly create balanced scorecards for stakeholder review It helps identify the Minimum Viable Product for evaluating the hypothesis It helps link objective production data to the hypothesis being tested What are two reasons for test data management? (Choose two.) To provide a viable option for disaster-recovery management To track the results of automated test cases for use by corporate audit To automate provisioning data to an application in order to set it to a known state before testing begins To generate synthetic test data inputs in order to validate test scenarios for automated tests maintained in version control To truncate data from the database to enable fast-forward recovery Feature toggles are useful for which activity? To enable continuous testing To enable continuous code integration To decouple deployment from release To prevent testing complexity What is a consequence of working in isolation on long-lived code branches? Static analysis tests will fail Trunk/Main will not always be in a deployable state Rollbacks will be difficult Deployments will fail Which incident response practice most strongly suggests a lack of DevOps culture? Manual rollback procedures On-call developers Frequent server reboots Frequent fix-forward changes When does the Continuous Integration dimension of the Continuous Delivery Pipeline begin? When code is checked in to version control When the Team Backlog has been refined When a feature has been pulled for work When a user story has satisfied its definition of done Which statement illustrates the biggest bottleneck? LT = 10 days, PT = 0.5 day, %C&A = 100% LT = 1 day, PT = 0.5 day, %C&A = 90% LT = 6 days, PT = 5 days, %C&A = 100% LT = 5 days, PT = 2.5 days, %C&A = 100% What are the first two areas that should be identified in value stream mapping? (Choose two.)You have reached the max number of allowed answers Process time, lead time, and percent complete and accurate The steps The bottlenecks The people who do the work The people who supervise the work Which steps in the value stream should be the main focus when choosing the most important improvement items? Steps with a long process time Steps with a high activity ratio Steps with short process time and short lead time in the future-state map Steps with long lead time and short process time in the current-state map Which metric reflects the quality of output at each step in the value stream? Deployment frequency Escaped defects %C/A - percent complete and accurate Process Time Which technical practice incorporates build-time identification of security vulnerabilities in the code? Threat Modeling Penetration Testing Dynamic Code Analysis Application Security 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? Failover/disaster recovery Design for operations Continuous security monitoring DevSecOps What identifies potential changes to the current state value stream that could improve flow? Impact mapping Problem-Solving Workshop Value stream identification Future state mapping What are the top two advantages of mapping the current state of the delivery pipeline? (Choose two.)You have reached the max number of allowed answers To help identify and make short-term fixes To enable everyone in the organization to see how the value stream is actually performing To achieve a collective understanding and consensus around problems To identify some of the processes within the delivery pipeline To help with incremental software delivery Which is true about the "Boundaries and Limitations" portion of the DevOps Transformation Canvas? It captures the people who need to be involved in the DevOps transformation It captures cultural constraints that will prevent us from ever moving forward It captures actions that require the support of other people or teams It captures lower priority improvement items Where do features go after Continuous Exploration? Into Continuous Integration where they are merged and tested with other Features Into a backlog tool where they are then split into Epics Into development where they are then split into Stories Into the Program Backlog where they are then prioritized What are two benefits of DevOps? (Choose two.) Fewer defects Tightly coupled architecture Faster lead time Increase batch size Better alignment between strategy and execution What is the recommended way to prioritize the potential items for the DevOps transformation? Minimum Viable Product Lean Business Case Minimum Marketable Feature Weighted Shortest Job First When full deployment automation is not possible, which practice helps developers deploy code into production? Infrastructure as code Deployment automation Self-service deployment Continuous deployment Which two statements describe thepurpose of value stream mapping? (Choose two.) To deliver incremental value in the form of working, tested software, and systems To visualize how value flows To understand the Product Owner's priorities To create an action plan for continuous improvement To create an understanding of the budget Security vulnerability scanning is an important architectural consideration in which dimension of the DevOps Health Radar? Release on Demand Continuous Exploration Continuous Deployment Continuous Integration What can impede the progress of a DevOps transformation the most?6 Lack of funding for CI/CD Pipeline tools When various groups in the organization have different directions and goals When teams use frequent retrospectives When there is no DevOps team What triggers the release activity? Change validated in staging environment Successful user acceptance tests Business decision to go live Successful deployment to production What marks the beginning of the Continuous Delivery Pipeline? A committed feature An idea A checked-in change A committed user story A canary release involves releasing value to whom? One subset of users at a time External users only Internal users first Internal users only How is Lean UX used in Continuous Exploration? To validate the return on investment To create a platform to continuously explore To automate the user interface scripts To collaboratively create a benefit hypothesis What does value stream mapping help reveal in the Continuous Delivery Pipeline? Where documentation should be reduced Who is responsible for optimizing the value stream Bottlenecks to the flow of value Where automation is needed [Show More]
