• Question 31:

  How is Lean UX used in Continuous Exploration?

  A. To automate the user interface scripts
  B. To create a platform to continuously explore
  C. To validate the return on investment
  D. To identify minimum marketable features
  D. To identify minimum marketable features

  ---

  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.

• Question 32:

  What are two benefits of DevOps? (Choose two.)

  A. Less frequent deployments
  B. More lead time
  C. Less time spent on new work
  D. Fewer defects
  E. Less time spent fixing security issues
  D. Fewer defects
  E. Less time spent fixing security issues

  ---

  Explanation

  Two benefits of DevOps are fewer defects and less time spent fixing security issues. 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 -- a high-performance innovation engine capable of delivering market-leading solutions at the speed of business. DevOps has many benefits for the enterprise, such as: Fewer defects ?DevOps improves the quality and consistency of the solution by enforcing frequent testing and validation throughout the solution lifecycle. DevOps applies various testing techniques and tools, such as unit testing, integration testing, acceptance testing, performance testing, and security testing, to verify that the solution meets the functional and nonfunctional requirements and standards. DevOps also enables early detection and resolution of defects, by implementing fast and frequent feedback loops within and across the value stream. DevOps reduces the cost and risk of defects, by shifting quality left and building quality in, rather than inspecting quality out. Less time spent fixing security issues ?DevOps enhances the security and compliance of the solution by integrating security practices into the value stream. DevOps applies the DevSecOps approach, which emphasizes the importance of proper information security practices in the pursuit of continuous delivery. DevSecOps involves applying automated tools and processes to detect and respond to security threats and vulnerabilities in the development and production environments, and ensuring compliance with security policies and standards. DevSecOps also involves collaborating with security teams and stakeholders, to foster a culture of shared responsibility and awareness for security. DevSecOps reduces the time and effort spent on fixing security issues, by shifting security left and building security in, rather than bolting security on8

• Question 33:

  Weighted shortest job first (WSJF) is applied to backlogs to identify what?

  A. Epics, Features, and Capabilities
  B. User business value
  C. Relative economic value
  D. Proxy for job size
  C. Relative economic value

  ---

  Explanation

  According to the SAFe DevOps Practitioner 6.0 study guide and handbook, Weighted Shortest Job First (WSJF) is applied to backlogs to identify relative economic value. This means that the WSJF algorithm uses factors such as user and business value, time criticality, risk reduction and/or opportunity enablement, and job size to rank the jobs in the backlog based on their economic benefit. The handbook states that "WSJF is estimated as the relative cost of delay divided by the relative job duration."1 Therefore, WSJF helps teams prioritize their backlog items for continuous delivery.

• Question 34:

  The Continuous Exploration aspect primarily supports which key stakeholder objective?

  A. Hypothesize
  B. Business value
  C. Alignment
  D. Research and development
  C. Alignment

  ---

  Explanation

  The Continuous Exploration aspect in SAFe primarily supports the key stakeholder objective of aligning business and technology. This phase focuses on exploring market needs and defining solutions that deliver the most significant customer and business value within the constraints of technology and feasibility. It helps ensure that the development efforts are in sync with business goals and market demands, thereby fostering alignment between various stakeholders..

• Question 35:

  What does Flow Efficiency measure in the Value Stream?

  A. The percentage of time spent on delays to the number of processes in the Value Stream
  B. The percentage of time spent on value-added activities
  C. The percentage of time spent on non-value-added activities
  D. The percentage of time spent on manual activities
  B. The percentage of time spent on value-added activities

  ---

  Explanation

  The correct answer is

  B. Flow Efficiency measures the percentage of time spent on value- added activities in the Value Stream. A Value Stream is a sequence of activities that deliver value to the customer, from concept to cash. Value-added activities are those that directly contribute to the customer value proposition, such as coding, testing, and deploying. Non- value-added activities are those that do not directly contribute to the customer value proposition, such as waiting, handoffs, rework, and approvals. Flow Efficiency is calculated by dividing the total time spent on value-added activities by the total flow time, which is the time elapsed from when a work item enters the Value Stream to when it is delivered to the customer. Flow Efficiency is a metric that helps to identify and eliminate waste and delays in the Value Stream, and to optimize the flow of value to the customer. Flow Efficiency can be improved by applying the principles and practices of DevOps, such as reducing batch size, limiting work in progress, implementing pull systems, managing queue lengths, reducing handoffs, implementing Work in Process (WIP) visualization, and implementing Work in Process (WIP) feedback

• Question 36:

  Where do features go after Continuous Exploration?

  A. Into Continuous Integration, where they are deployed with feature toggles
  B. Into Continuous Development, where they are implemented in small batches
  C. Into the Portfolio Backlog, where they are then prioritized
  D. Into Continuous Integration, where they are then split into Stories
  D. Into Continuous Integration, where they are then split into Stories

  ---

  Explanation

  In the Scaled Agile Framework (SAFe), after features are defined and designed during Continuous Exploration, they move into Continuous Integration. Here, they are further broken down into smaller, implementable parts known as user stories. These stories are then developed, tested, and integrated into the existing codebase. This process ensures that new features are developed in a systematic and efficient manner, with regular integration and testing to maintain quality and readiness for release.

• Question 37:

  DevOps is a key enabler of continuous delivery.

  What does continuous mean in this context?

  Choose the correct option from below list

  A. To deploy to production and release on cadence every Iteration
  B. To deploy to production and release at least once every Program increment
  C. To deploy to production as often as possible and release when the business needs it
  D. To deploy to production multiple times per year and release on a cadence once or twice a year
  C. To deploy to production as often as possible and release when the business needs it

  ---

  Explanation

  Continuous means to deploy to production as often as possible and release when the business needs it in the context of continuous delivery in SAFe DevOps. Continuous delivery is the ability to deliver value to the end user whenever there is a business need. It requires a Continuous Delivery Pipeline (CDP) that supports the integration, automation, and collaboration needed to effectively develop and operate a solution. Continuous delivery enables the enterprise to respond to changing customer needs and market conditions with speed and quality. Continuous delivery does not mean releasing every change to the end user immediately. Rather, it means decoupling deployment from release, and allowing the business to decide when to release the new functionality based on customer demand and economic outcomes1

• Question 38:

  Who is responsible for building and continually improving the Continuous Delivery Pipeline?

  Choose the correct option from below list

  A. System Teams
  B. Agile Release Trains
  C. Scrum Teams
  D. DevOps Teams
  B. Agile Release Trains

  ---

  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

• Question 39:

  Identifying the Minimal Marketable Feature is part of what? Choose the correct option from below list

  A. Lean Principles
  B. Lean Leadership
  C. Lean Startup
  D. Lean UX
  D. Lean UX

  ---

  Explanation

  Identifying the Minimal Marketable Feature (MMF) is part of Lean UX, which is a user- centric approach to designing and delivering products. An MMF is a small, self-contained feature that can be developed quickly and that delivers significant value to the user. It is the smallest unit of functionality that can be released to the market and generate feedback. Lean UX advocates for releasing MMFs as early and often as possible, to validate assumptions, learn from users, and iterate on the product

• Question 40:

  Which two statements describe the purpose of value stream mapping? (Choose two.)

  Choose the correct option from below list

  A. To deliver incremental value in the form of working, tested software and systemscorrect
  B. To create an understanding of the budget
  C. To create an action plan for continuos improvement
  D. To understand the Product Owner's priorities
  E. To visualize how value flows
  A. To deliver incremental value in the form of working, tested software and systemscorrect
  E. To visualize how value flows

  ---

  Explanation

  The purpose of value stream mapping is to visualize how value flows from concept to cash and to deliver incremental value in the form of working, tested software and systems. Value stream mapping helps to identify the current state of the value stream, the steps, activities, roles, and tools involved, and the delays, waste, and inefficiencies that can be eliminated or improved. It also helps to create a future state vision and an action plan for continuous improvement
