To create a strong DevO ... ps team with leadership support To create immutable infrastructure to avoid changes to the production environment To align people across the Value Stream to deliver value continuously To implement an advanced tool chain to automate the entire Continuous Delivery Pipeline What are two important items to monitor in production to support the Release on Demand aspect in SA Deployment lead time System performance Time-to-market Lead time to defect fixing Business value Which statement describes the Lean startup lifecycle? Define a Lean business case, build a minimum viable product, implement the Epic Features until all Features a Define the minimum viable product (MVP), build the MVP, implement Epic Features until all Features are delive Create a hypothesis statement, assign an Epic owner, deliver Features created from the Lean business case, d Define the hypothesis, build a minimum viable product (MVP), continuously evaluate the MVP while implement DevOps is a key enabler of continuous delivery. What does continuous mean in this context? WRONG To deploy to production and release at least once every Program increment To deploy to production multiple times per year and release on a cadence once or twice a year To deploy to production and release on cadence every Iteration To deploy to production as often as possible and release when the business needs it Which term describes the time it takes value to flow across the entire Value Stream? Total lead time Rolled percent complete and accurate Activity ratio Deployment frequency When preparing a DevOps backlog, prioritizing features using WSJF includes which two factors? (Cho Team velocity Business valueTotal count of items on the Program Backlog Duration/job size Cost of delay What is the primary benefit of value stream mapping? It creates the hypothesis of which Solution to build It provides insight into organizational efficiency and value flow It identifies how to build Agile Release Trains It fosters collaboration among development and operations managers Value stream mapping metrics include calculations of which three Metrics? (Choose three.) Rolled % Complete and Accurate Emergency Change % Outage Frequency Release Frequency Total Process Time Activity Ratio Which statement describes a measurable benefit of adopting DevOps practices and principles? It creates a highly functional, cross-team culture It guarantees an increase in profits and decrease in downtime It results in faster lead time, and more frequent deployments It identifies key Value Streams What is trunk-based development? Teams with similar dependencies create one single branch for the team's work All teams committing their code into one trunk Each developer maintains a separate branch Every team works in their own trunk The Release on Demand aspect enables which key business objective? Business value Alignment Time-to-market Quality What is the primary purpose of creating an automated test suite? To increase unit test coverage during an Iteration To enable continuous testing To eliminate all manual testing To increase the return on investment for finding defects What falls outside the scope of the Stabilize activity?Failover and recovery processes are in place Blue/green deployment Continuous security monitoring is done Features are monitored after release Value flows through which aspect in the Continuous Delivery Pipeline? Monitor Continuous Integration Develop Research What is the blue/green deployment pattern? To deploy between an inactive and active environment To deploy to only some data centers to reduce the deployment risk To ensure no changes happen in production without going through the Continuous Delivery Pipeline To decouple deployment from release In what activity of Continuous Exploration are Features prioritized in the Program Backlog? Finalize Synthesize Hypothesize Research What is the purpose of a minimum viable product? To validate the hypothesis To sell to new markets To demo to Product Management for feedback To release to production Which two areas should be monitored in the Release on Demand aspect to support DevOps and Contin answers Agile Release Train velocity Build status Full-stack system behavior Business Metrics Deployment cycle time Which DevOps principle focuses on identifying and eliminating bottlenecks in the Continuous Delivery Recovery Measurement Automation Lean flowWhy are canary releases used? To introduce minimum viable features To allow incremental release To reduce deployment times To prevent outages Which practice prevents configuration drift between production and non-production environments? W Deployment automation Immutable infrastructure Session replay Self-service deployment What is the correct order of activities in the Continuous Integration aspect? Build, Develop, Stage, Test end-to-end Develop, Test end-to-end, Build, Stage Develop, Build, Test end-to-end, Stage Stage, Develop, Build, Test end-to-end Who is responsible for building and continually improving the Continuous Delivery Pipeline? DevOps Teams System Teams Agile Release Trains Scrum Teams Who is responsible for ensuring quality is built into the code in SAFe? Developers Agile Teams Testers Product Owners What is one recommended way to architect for operations? WRONG Implement feature toggles Require developers to support their own code Establish an architecture review board Create detailed run books Which statement is true about DevOps? It enables a tolerance for low-risk, low-failure, and rapid recovery It enables low-risk releases and fast recovery with no room for errors It enables high-risk releases and fast recovery with fast fix-forward It enables low-risk releases and fast recovery with fast fix-forwardWhich technical practice is key to enabling trunk-based development? WRONG Feature branching Refactoring Code freezes Gated commits Who should be consulted first when calculating the % Complete and Accurate? End users The people responsible for the next step The lead developer Testers What is the primary goal of the Stabilize activity? To achieve active-active site replication To establish quality-of-service agreements with customers To enhance stability with blue/green deployment To avoid unplanned outages and security breaches What is the desired frequency of deployment in SAFe? Daily Once per Iteration Once per PI Continuous One goal of DevOps in SAFe is to fully automate the steps between which two pipeline activities? Code commit and stage Code commit and user acceptance testing Code commit and deploy Code commit and release What are two aspects of the Continuous Delivery Pipeline, in addition to Continuous Integration? (Cho Continuous Release Continuous Deployment Continuous Testing Continuous Improvement Continuous Exploration What does the %C&A metric measure in the Continuous Delivery Pipeline? The percent of time downstream customers receive work that is usable as-is The percent concurrent and accurate process times of each pipeline activity The percent of change averages of each pipeline activity The percent complete and average times of each pipeline activityMapping the value stream helps accomplish which two actions? (Choose two.)You have reached the To serve as a blueprint for development To gain insight into organizational efficiency To add or remove user segments based on business decisions To understand how the flow of value can be improved To prioritize the Program Backlog Which two security skills are part of the Continuous Integration aspect? (Choose two.)WRONG Application security Penetration testing SOX compliance analysis Network security practices Security board review What are two benefits of DevOps? (Choose two.) Less time spent on new work Less time spent fixing security issues Fewer defects Less frequent deployments More lead time Which skill can significantly accelerate mean-time-to-restore by enabling support teams to see issues Session replay Incident management Page analytics Blue/green deployment Why is it important to take a structured approach to analyze problems in the delivery pipeline? It allows the solution to be demoed to key stakeholders It helps ensure that actual causes of problems are addressed, rather than symptoms It provides a structured roadmap for the SAFe implementation It ensures that solutions are more likely to be approved for implementation What does Culture in a CALMR approach mean? A culture where developers code and operations deploys A culture where technical expertise is paramount A culture of shared responsibility and risk tolerance A culture where development and operations report to the same manager Which two technical practices focus on Built-in Quality? (Choose two.) Environment configuration Feature togglesCanary releases Pair work Test-driven development [Show More]
