When should teams use root cause analysis to address impediments to continuous delivery?
- A. During Inspect & Adapt (I&A)
- B. During the management review and problem-solving portion of PI Planning
- C. During the Iteration Retrospective
- D. During Iteration Planning
Answer: A
Explanation:
Explanation
According to the SAFe DevOps Practitioner 6.0 study guide1, root cause analysis is a technique that helps identify and eliminate the underlying causes of problems or defects in the Solution. Root cause analysis can be used to address impediments to continuous delivery by finding and fixing the root causes of issues such as delays, rework, waste, and errors. Root cause analysis can be performed during various phases of the PI, such as during the Iteration Retrospective, during the management review and problem-solving portion of PI Planning, or during Inspect & Adapt (I&A). However, the most effective time to use root cause analysis is during I&A, which is a significant event held at the end of each PI, where the current state of the Solution is demonstrated and evaluated. Teams then reflect and identify improvement backlog items via a structured problem-solving workshop. The result is a set of improvement backlog items that go into the ART Backlog for the next PI Planning event. Therefore, root cause analysis can help teams address impediments to continuous delivery by improving their performance and quality in the next PI.

NEW QUESTION # 46
Who is responsible for building and continually improving the Continuous Delivery Pipeline?
Choose the correct option from below list
- A. Agile Release Trains
- B. DevOps Teams
- C. System Teams
- D. Scrum 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 # 47
Which DevOps principle focuses on identifying and eliminating bottlenecks in the Continuous Delivery Pipeline?
- A. Recovery
- B. Automation
- C. Measurement
- D. Lean flow
Answer: D
Explanation:
Explanation
Lean flow is the DevOps principle that focuses on identifying and eliminating bottlenecks in the Continuous Delivery Pipeline. Lean flow is the application of Lean thinking and principles to optimize the flow of value from ideation to delivery. Lean flow aims to reduce waste, increase efficiency, and deliver value faster and more reliably. Lean flow involves the following practices:
Reducing batch size - Breaking down large batches of work into smaller, more manageable pieces that can be delivered more frequently and with less risk.
Limiting work in progress (WIP) - Restricting the amount of work that can be started or in flight at any given time, to avoid overloading the system and creating queues and delays.
Implementing pull systems - Aligning the production and consumption of work by allowing downstream customers to pull work from upstream suppliers when they are ready, rather than pushing work based on forecasts or schedules.
Managing queue lengths - Monitoring and controlling the amount of work waiting to be processed at each stage of the value stream, to reduce lead time and variability.
Reducing handoffs - Minimizing the number of transitions and dependencies between different teams or individuals, to avoid communication gaps, context switching, and rework.
Implementing Work in Process (WIP) visualization - Making the work and its status visible to all stakeholders, using tools such as Kanban boards, Cumulative Flow Diagrams (CFDs), and Value Stream Maps (VSMs), to enable collaboration, coordination, and improvement.
Implementing Work in Process (WIP) feedback - Establishing fast and frequent feedback loops within and across the value stream, using tools such as automated testing, monitoring, and metrics, to detect and resolve issues, validate assumptions, and learn from outcomes3
NEW QUESTION # 48
Innovation accounting stresses the importance of avoiding what?
- A. Quantitative metrics
- B. ROI calculations
- C. Vanity metrics
- D. Objective metrics
Answer: C
Explanation:
Explanation
Innovation accounting stresses the importance of avoiding vanity metrics. Vanity metrics are metrics that look good on paper but do not reflect the true value or impact of an innovation. Examples of vanity metrics include the number of downloads, page views, followers, or likes, which may not indicate whether the users are actually engaged, satisfied, or loyal to the product or service. Vanity metrics can be misleading, deceptive, or irrelevant, and can cause the enterprise to waste time and resources on pursuing the wrong goals or strategies.
Innovation accounting, on the other hand, is a term coined by Eric Ries in his book The Lean Startup, which describes a process of measuring and learning from the outcomes of innovation experiments. Innovation accounting involves defining the hypothesis, building the minimum viable product (MVP), and evaluating the results using actionable metrics. Actionable metrics are metrics that demonstrate the cause and effect relationship between the actions taken and the outcomes achieved. Examples of actionable metrics include the conversion rate, retention rate, revenue per customer, or customer satisfaction score, which can indicate whether the product or service is delivering value to the customer and the enterprise. Actionable metrics can help the enterprise to validate or invalidate the hypothesis, and to decide whether to pivot or persevere with the innovation78
NEW QUESTION # 49
What is one potential outcome of the Verify activity of the Continuous Delivery Pipeline?
- A. Analyze regression testing results
- B. Capture usage metrics from a canary release
- C. Roll back a failed deployment
- D. Fix a broken build
Answer: A
Explanation:
Explanation
According to the SAFe DevOps Practitioner 6.0 study guide and handbook, one potential outcome of the Verify activity of the Continuous Delivery Pipeline is to analyze regression testing results. This means that the Verify activity involves checking the functionality and performance of the Solution after a deployment, and comparing it with the expected results. The handbook states that "Verify is the activity of checking the functionality and performance of the Solution after a deployment, and comparing it with the expected results."1 Therefore, one of the possible outcomes of this activity is to analyze how well the Solution meets the quality standards and customer requirements.

What can impede the progress of a DevOps transformation the most?
- A. When teams use frequent retrospectives
- B. When various groups in the organization have different directions and goals
- C. When there is no DevOps team
- D. Lack of funding for CI/CD pipeline tools
Answer: B
Explanation:
Explanation
According to the SAFe DevOps Practitioner 6.0 study guide1, one of the main challenges of a DevOps transformation is when various groups in the organization have different directions and goals. This can create silos, conflicts, and inefficiencies that hinder the collaboration and integration needed for continuous delivery.
For example, some groups may prioritize speed over quality, while others may prioritize security over innovation. Some groups may resist change and adopt outdated practices, while others may embrace new technologies and methodologies. These differences can lead to misalignment, duplication, and waste of resources that slow down the delivery pipeline and reduce the value to customers. Therefore, having a common vision, culture, and set of technical practices that support the SAFe CALMR approach to DevOps is essential for overcoming this challenge.
NEW QUESTION # 54
How frequently should Agile Release Trains release?
Choose the correct option from below list
- A. One per PI
- B. Continuously
- C. Once per iteration
- D. On demand
Answer: D
Explanation:
Explanation
Agile Release Trains (ARTs) should release on demand, which means releasing new functionality immediately or incrementally based on business and customer needs. Release on demand is the final aspect of the Continuous Delivery Pipeline (CDP) in SAFe DevOps, which enables the delivery of value to the end user as fast as possible, based on market demand. The decision of what and when to release is a critical economic driver that requires careful consideration of the customer needs, market rhythms, and economic outcomes. Release on demand is decoupled from the Continuous Deployment activity, which automates the migration of new functionality from a staging environment to production, where it is made available for release

Which skill can significantly accelerate mean-time-to-restore by enabling support teams to see issues the way actual end users did?
- A. Incident management
- B. Session replay
- C. Blue/green deployment
- D. Page analytics
Answer: B
Explanation:
Explanation
One skill that can significantly accelerate mean-time-to-restore by enabling support teams to see issues the way actual end users did is session replay. Session replay is a technique that allows the support team to replay end-user sessions to research incidents and identify problems. Session replay captures the user's interactions with the application, such as clicks, scrolls, keystrokes, and mouse movements, and reproduces them in a video-like format. Session replay can help the support team to understand the user's behavior, context, and feedback, as well as to reproduce and diagnose errors, bugs, and performance issues. Session replay can also help the support team to communicate and collaborate with the development team and the stakeholders, by providing visual evidence and data of the incidents. Session replay can significantly accelerate mean-time-to-restore by reducing the time and effort required to investigate and resolve issues, as well as by improving the quality and reliability of the application
