The DevOps Health Radar aligns the four aspects of the Continuous Delivery Pipeline to which four stakeholder concerns?
- A. Portfolio, Solution, ART, team
- B. Exploration, integration, development, reflection
- C. Alignment, quality, time-to-market, business value
- D. Productivity, efficiency, speed-to-market, competitive advantage
Answer: C
Explanation:
Explanation
The DevOps Health Radar aligns the four aspects of the Continuous Delivery Pipeline to four stakeholder concerns: alignment, quality, time-to-market, and business value. The DevOps Health Radar is a tool that helps Agile Release Trains (ARTs) and Solution Trains assess their ability to Release on Demand, which is the process of delivering value to customers whenever there is a business need. The DevOps Health Radar consists of four dimensions that correspond to the four aspects of the Continuous Delivery Pipeline: Continuous Exploration (CE), Continuous Integration (CI), Continuous Deployment (CD), and Release on Demand. Each dimension has four sub-dimensions that reflect the key practices and capabilities that enable the flow of value.
The DevOps Health Radar helps the ARTs and Solution Trains to measure their maturity in each sub-dimension, using a scale of Sit, Crawl, Walk, Run, or Fly. The DevOps Health Radar also helps the ARTs and Solution Trains to identify the gaps and improvement opportunities in their DevOps practices, and to prioritize the next steps toward achieving higher levels of maturity. The DevOps Health Radar aligns the four aspects of the Continuous Delivery Pipeline to four stakeholder concerns, as shown in Figure 1:
Alignment - Alignment is the concern of ensuring that the solution is aligned with the customer needs, market opportunities, and strategic goals of the enterprise. Alignment is achieved by applying the CE aspect, which involves exploring the market and customer problems, defining a vision, roadmap, and set of features for the solution, and validating the assumptions and hypotheses with customer feedback and data.
Quality - Quality is the concern of ensuring that the solution meets the functional and nonfunctional requirements and standards, and that it does not introduce any defects or vulnerabilities. Quality is achieved by applying the CI aspect, which involves developing, testing, integrating, and validating new functionality in preparation for deployment and release.
Time-to-market - Time-to-market is the concern of ensuring that the solution can be delivered and deployed to the production environment as fast and as frequently as possible, without compromising quality or security. Time-to-market is achieved by applying the CD aspect, which involves automating and streamlining the deployment process, and ensuring the stability and reliability of the production environment.
Business value - Business value is the concern of ensuring that the solution delivers the expected outcomes and benefits to the customer and the enterprise, and that it can be adapted and improved based on the changing needs and feedback. Business value is achieved by applying the Release on Demand aspect, which involves releasing new functionality to the customer incrementally or immediately, based on the market demand, and measuring and learning from the results12

NEW QUESTION # 39
Why is it important to take a structured approach to analyze problems in the delivery pipeline?
- A. It ensures that solutions are more likely to be approved for implementation
- B. It allows the solution to be demoed to key stakeholders
- C. It helps ensure that actual causes of problems are addressed, rather than symptoms
- D. It provides a structured roadmap for the SAFe implementation
Answer: C
Explanation:
Explanation
The reason why it is important to take a structured approach to analyze problems in the delivery pipeline is that it helps ensure that actual causes of problems are addressed, rather than symptoms. A structured approach to problem analysis involves following a systematic and logical process to identify, define, and understand the root causes of a problem, and to propose and evaluate possible solutions. A structured approach can help avoid jumping to conclusions, making assumptions, or applying band-aid fixes that do not solve the underlying issues. A structured approach can also help involve the relevant stakeholders, collect and analyze data, prioritize and categorize problems, and communicate and document the findings and recommendations. Some examples of structured approaches to problem analysis are the 5 Whys, the fishbone diagram, the Pareto chart, and the PDCA cycle
NEW QUESTION # 40
What does the %C&A metric measure in the Continuous Delivery Pipeline?
- A. The percent complete and average times of each pipeline activity
- B. The percent concurrent and accurate process times of each pipeline activity
- C. The percent of change averages of each pipeline activity
- D. The percent of time downstream customers receive work that is usable as-is
Answer: D
Explanation:
Explanation
The %C&A metric measures the percent of time downstream customers receive work that is usable as-is in the Continuous Delivery Pipeline. The %C&A metric is a measure of the quality of the work output from a process step. It indicates the percentage of time that the downstream customers receive work that is acceptable as is, without any rework or errors. To calculate the %C&A metric, the people responsible for the next step need to inspect the work output from the previous step and determine whether it meets the quality standards and expectations. They also need to provide feedback to the previous step on the defects or issues they find and how they affect the value stream. By measuring the %C&A metric, the enterprise can gain insight into the current state of the delivery process, such as the lead time, cycle time, throughput, quality, and waste. This insight can help the enterprise identify bottlenecks, dependencies, handoffs, delays, and inefficiencies that affect the flow of value. The %C&A metric can also help the enterprise understand how the flow of value can be improved by applying the principles and practices of DevOps, such as culture, automation, lean flow, measurement, and recovery. By improving the %C&A metric, the enterprise can increase customer satisfaction, reduce costs, accelerate time-to-market, and enhance business agility
NEW QUESTION # 41
What is the desired frequency of deployment in SAFe?
Choose the correct option from below list
- A. Once per Iteration
- B. Once per PI
- C. Continuous
- D. Daily
Answer: C
Explanation:
Explanation
The desired frequency of deployment in SAFe is continuous, meaning that new functionality can be deployed to production as soon as it is ready, without waiting for fixed release dates or schedules. Continuous deployment is an aspect of the CDP that automates the migration of new functionality from a staging environment to production, where it is made available for release. Continuous deployment enables the ability to release value at any time, in a sustainable way

- A. Failover/disaster recovery
- B. Design for operations
- C. Continuous security monitoring
- D. Security Operations
Answer: C
Explanation:
Explanation
Ensuring that security controls like threat modeling, application security, and penetration testing are in place throughout the Continuous Delivery Pipeline is an example of Continuous security monitoring. This skill involves the ongoing assessment and oversight of security measures within the pipeline to ensure that the software remains secure against potential threats at all stages of its development and deployment.
NEW QUESTION # 43
What is the purpose of the blue/green deployment pattern?
- A. To decouple deployment from release - xx
- B. To deploy to only some data centers to reduce the deployment risk
- C. To ensure no changes happen in production without going through the Continuous Delivery Pipeline
- D. To deploy between an inactive and active environment
Answer: D
Explanation:
Explanation
The purpose of the blue/green deployment pattern is to deploy between an inactive and active environment.
The blue/green deployment pattern is a change management strategy for software releases that reduces the downtime and risk of deploying new versions of software. The blue/green deployment pattern involves having two identical but separate environments: one is the active environment (blue) that serves the user traffic, and the other is the inactive environment (green) that hosts the new version of the software. The deployment process consists of switching the user traffic from the blue environment to the green environment, after verifying that the new version is working properly. The blue environment can then be kept as a backup or updated to become the next green environment. The blue/green deployment pattern has several benefits, such as:
It allows for fast and reliable rollback, in case of any issues or errors in the new version, by simply switching back to the blue environment.
It eliminates the need for complex and error-prone migration scripts, as the green environment can be prepared and tested in advance, without affecting the blue environment.
It enables testing and experimentation of the new version with a subset of users, by directing some user traffic to the green environment, before switching completely.
It facilitates continuous delivery and deployment, by automating the switching process and reducing the transaction cost and risk of moving changes to production
NEW QUESTION # 44
Who is responsible for building and continually improving the Continuous Delivery Pipeline?
Choose the correct option from below list
- A. Agile Release Trains
- B. Scrum Teams
- C. DevOps Teams
- D. System Teams
Answer: A
Explanation:
Explanation
The Agile Release Trains (ARTs) are responsible for building and continually improving the Continuous Delivery Pipeline (CDP) in SAFe DevOps. The CDP represents the workflows, activities, and automation needed to guide new functionality from ideation to an on-demand release of value. The CDP consists of four aspects: Continuous Exploration (CE), Continuous Integration (CI), Continuous Deployment (CD), and Release on Demand. Each ART builds and maintains, or shares, a pipeline with the assets and technologies needed to deliver solution value as independently as possible. The ARTs use the DevOps Health Radar to assess their current state and identify improvement opportunities for each aspect of the CDP. The ARTs also use the DevOps Transformation Canvas to create a vision, goals, and action plan for their DevOps transformation12
NEW QUESTION # 45
What is true about the Boundaries and Limitations portion of the DevOps Transformation Canvas?
Choose the correct options from below list
- A. It captures budget constraints that will prevent DevOps improvements
- B. It captures the people who need to be involved in the DevOps transformation
- C. It captures the lowest priority improvement items
- D. It captures improvement items that require the support of other people or teams
Answer: D
Explanation:
Explanation
The Boundaries and Limitations portion of the DevOps Transformation Canvas is used to capture improvement items that require the support of other people or teams. These are items that are outside the scope or control of the current team or value stream, but are necessary for achieving the DevOps vision and goals. They help to identify dependencies, risks, and stakeholders that need to be engaged or aligned
NEW QUESTION # 46
Which steps in the value stream should be the main focus when prioritizing improvement items?
- A. Steps with a long Active Time
- B. Steps with low Percent Complete and Accurate (%C&A) and short Active Time in the current-state map
- C. Steps with a high Flow Efficiency
- D. Steps with short Active Time and high %C&A in the future-state map
Answer: D
Explanation:
Explanation
According to the SAFe DevOps Practitioner 6.0 study guide1, when prioritizing improvement items, the steps with short Active Time and high %C&A in the future-state map should be the main focus. Active Time is the amount of time a step spends on performing work, while %C&A is the percentage of capacity utilization of a step. The future-state map shows how the Value Stream will look like after implementing improvements, based on customer feedback and business value. The improvement items are ranked by their impact on flow efficiency, customer satisfaction, and business agility. The steps with short Active Time and high %C&A in the future-state map indicate that they are bottlenecks or waste sources that need to be eliminated or reduced as soon as possible. Therefore, they should be prioritized for improvement actions.
NEW QUESTION # 47
What is the purpose of a minimum viable product?
- A. To release to production
- B. To sell to new markets
- C. To validate the hypothesis
- D. To demo to Product Management for feedback
Answer: C
Explanation:
Explanation
The purpose of a minimum viable product is to validate the hypothesis. A minimum viable product (MVP) is an early and minimal version of a new product or solution used to prove or disprove an epic hypothesis. An epic is a significant solution development initiative that requires the definition and approval of an MVP. An epic hypothesis is a statement that describes the expected outcome, benefit, and value of an epic. The MVP is the smallest possible solution that can be used to test the epic hypothesis with real customers or users, and to gather feedback and data. The MVP helps reduce the risk of investing in a solution that nobody wants or needs, and enables faster learning and adaptation. The MVP is not the final product or solution, but rather a starting point for further development and improvement
NEW QUESTION # 48
What is a consequence of working in isolation on long-lived code branches?
- A. Trunk/main will not always be in a deployable state
- B. End-to-end tests will fail
- C. Rollbacks will be difficult
- D. Deployments will fail
Answer: A
Explanation:
Explanation
According to the SAFe DevOps Practitioner 6.0 study guide and handbook, working in isolation on long-lived code branches can have negative consequences for the Continuous Delivery Pipeline. This includes making the trunk/main branch less stable and more prone to conflicts and errors. The handbook states that "Working in isolation on long-lived code branches can make the trunk/main branch less stable and more prone to conflicts and errors."1 Therefore, it is recommended to use short-lived feature branches and merge them frequently into the trunk/main branch.
NEW QUESTION # 49
What is one benefit of DevOps?
- A. Increased batch size
- B. Fewer defects
- C. Better alignment between strategy and execution
- D. Tightly coupled architecture
Answer: C
Explanation:
Explanation
According to the SAFe DevOps Practitioner 6.0 study guide1, one of the benefits of DevOps is better alignment between strategy and execution. DevOps is a mindset, culture, and set of technical practices that supports the integration, automation, and collaboration needed to effectively develop and operate a solution.
DevOps helps break down organizational silos and develop a Continuous Delivery Pipeline (CDP) - a high-performance innovation engine capable of delivering market-leading solutions at the speed of business.
By aligning strategy and execution, DevOps enables teams to deliver value to customers faster and more reliably, as well as to adapt to changing market conditions and customer needs. Therefore, better alignment between strategy and execution is one of the benefits of DevOps.
NEW QUESTION # 50
What is the recommended way to prioritize improvement items for the DevOps transformation?
Choose the correct options from below list
- A. Weighted Shortest Job First
- B. Minimum Viable Product
- C. Minimum marketable feature
- D. Lean business Case
Answer: A
Explanation:
Explanation
The recommended way to prioritize improvement items for the DevOps transformation is to use Weighted Shortest Job First (WSJF). WSJF is a prioritization model that considers the cost of delay, job size, and economic value of each improvement item. It helps to identify the most urgent and valuable items that can be delivered in the shortest amount of time
NEW QUESTION # 51
What is the first area that should be identified in Value Stream Mapping?
- A. The people who supervise the work
- B. Active Time, Flow Time. and Percent Complete and Accurate (%C&A)
- C. The bottlenecks
- D. The steps
Answer: D
NEW QUESTION # 52
How is Lean UX used in Continuous Exploration?
- A. To validate the return on investment
- B. To create a platform to continuously explore
- C. To automate the user interface scripts
- D. To identify minimum marketable features
Answer: D
Explanation:
Explanation
According to the SAFe DevOps Practitioner 6.0 study guide1, Lean UX is used in Continuous Exploration to create a platform to continuously explore. Continuous Exploration is the process of creating alignment on what needs to be built, synthesizing Solution ideas into ART Backlog Features, and utilizing WSJF to prioritize a DevOps backlog. Lean UX is a team-based approach to building better products by focusing less on the theoretically ideal design and more on iterative learning, overall user experience, and customer outcomes.
Lean UX design extends the traditional UX role beyond merely executing design elements and anticipating how users might interact with a system. Instead, it encourages a far more comprehensive view of why a Feature exists, the functionality required to implement it, and the benefits it delivers. By getting immediate feedback to understand if the system will meet the fundamental business objectives, Lean UX provides a closed-loop method for defining and measuring value. Therefore, Lean UX is used in Continuous Exploration to create a platform that enables teams to experiment with different hypotheses, validate their assumptions, and learn from their failures.
NEW QUESTION # 53
When preparing a DevOps backlog, prioritizing features using WSJF includes which two factors? (Choose two.) Choose the correct option from below list
- A. Team velocity
- B. Cost of delay
- C. Business value
- D. Duration/job size
- E. Total count of items on the Program Backlog
Answer: B,D
Explanation:
Explanation
When preparing a DevOps backlog, prioritizing features using WSJF includes two factors: cost of delay and duration/job size. WSJF stands for Weighted Shortest Job First, which is a prioritization model used to sequence work for maximum economic benefit. WSJF is estimated as the relative cost of delay divided by the relative job duration. Cost of delay is the money lost by delaying or not doing a job for a specific time. It is a measure of the economic value of a job over time. Job duration is the time it takes to complete a job. Jobs that can deliver the most value in the shortest duration provide the best economic return. WSJF also considers other factors that contribute to the cost of delay, such as user and business value, time criticality, and risk reduction and/or opportunity enablement
