NEW QUESTION # 19
Which skill can significantly accelerate mean-time-to-restore by enabling support teams to see issues the way actual end users did?
- A. Session replay
- B. Incident management
- C. Page analytics
- D. Blue/green deployment
Answer: A
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

NEW QUESTION # 23
Which DevOps principle focuses on identifying and eliminating bottlenecks in the Continuous Delivery Pipeline?
- A. Lean flow
- B. Automation
- C. Recovery
- D. Measurement
Answer: A
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 # 24
What is the purpose of a minimum viable product?
- A. To demo to Product Management for feedback
- B. To sell to new markets
- C. To release to production
- D. To validate the hypothesis
Answer: D
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 # 25
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
Answer: D
Explanation:
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

NEW QUESTION # 27
What is trunk-based development?
- A. Every team works in their own trunk
- B. Each developer maintains a separate branch
- C. Teams with similar dependencies create one single branch for the team's work
- D. All teams committing their code into one trunk
Answer: D
Explanation:
Explanation
Trunk-based development is a version control management practice where all developers work on the same trunk of shared code. The trunk is always in a releasable state, which means that at least once a day, developers must integrate their changes to the trunk. This is accomplished through short-lived feature branches related to project tasks. Trunk-based development is a common practice among DevOps teams and part of the DevOps lifecycle since it streamlines merging and integration phases. It also enables continuous integration, which is the practice of merging all development versions of a code base several times a day. Trunk-based development has several benefits, such as:
It reduces the complexity and conflicts of merging long-lived branches
It improves the quality and consistency of the code by enforcing frequent testing and validation It accelerates the delivery and deployment of new functionality by minimizing the transaction cost and risk It fosters a culture of collaboration and transparency among developers

- B. Continuous
- C. Once per PI
- D. Daily
Answer: B
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
NEW QUESTION # 29
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

Two of the technical practices that focus on Built-in Quality are pair work and test-driven development. Pair work is a collaborative technique where two developers work together on the same code, one writing the code and the other reviewing it. Pair work improves the quality of the code by reducing defects, increasing knowledge sharing, and enhancing creativity and problem-solving. Test-driven development (TDD) is a practice where developers write automated tests before writing the code, and then refactor the code until it passes the tests. TDD ensures that the code meets the requirements and specifications, as well as improves the design, readability, and maintainability of the code
NEW QUESTION # 34
What work is performed in the Build activity of the Continuous Delivery Pipeline?
- A. Automated acceptance testing
- B. Compile
- C. Code
- D. Code review
Answer: B
Explanation:
Explanation
The correct answer is B. Compile. The Build activity of the Continuous Delivery Pipeline is responsible for creating deployable binaries and merging development branches into the trunk. The Build activity includes the following practices:
Compile - Compile is the process of transforming the source code into executable code that can run on a specific platform or environment. Compile involves checking the syntax, semantics, and dependencies of the code, and resolving any errors or conflicts. Compile also involves linking the code with other libraries or components that are required for the functionality of the solution.
Package - Package is the process of bundling the compiled code and other resources into a format that can be easily deployed to the target environment. Package involves creating archives, containers, or installers that contain the necessary files and metadata for the deployment process. Package also involves applying versioning and configuration information to the packages, to ensure traceability and consistency.
Verify - Verify is the process of ensuring that the code and packages meet the quality standards and security checks, and that they are ready for deployment and release. Verify involves applying automated tools and processes, such as static code analysis, code coverage, code review, and code quality metrics, to detect and resolve any issues or vulnerabilities in the code and packages. Verify also involves ensuring compliance with the coding standards and guidelines, and documenting the results and feedback of the verification process12
