One of the recommended ways to architect for operations is to implement feature toggles, which are mechanisms that allow developers to turn features on or off without redeploying the code. Feature toggles enable faster and safer deployments, as well as experimentation and testing in production. They also allow the operations team to control when and how new features are released to the end users, based on business needs and market demand. Feature toggles can also be used to mitigate risks and roll back changes in case of errors or failures
NEW QUESTION # 53
Which statement describes a measurable benefit of adopting DevOps practices and principles?
Choose the correct option from below list
- A. It results in faster lead time, and more frequent deployments
- B. It identifies key Value Streams
- C. It creates a highly functional, cross-team culture
- D. It guarantees an increase in profits and decrease in downtime
Answer: A
Explanation:
Explanation
One of the measurable benefits of adopting DevOps practices and principles is that it results in faster lead time and more frequent deployments. Lead time is the time it takes from the moment a change is requested until it is delivered to the customer. Frequent deployments are the number of times a change is deployed to production. Both of these metrics indicate the speed and efficiency of the DevOps process, as well as the ability to respond to customer needs and feedback. According to the State of DevOps Report 2020, high-performing DevOps teams have 208 times faster lead times and 106 times more frequent deployments than low-performing teams
NEW QUESTION # 54
What marks the beginning of the Continuous Delivery Pipeline?
- A. A committed user story
- B. A checked-in change
- C. An idea
- D. A committed Feature
Answer: C
Explanation:
Explanation
According to the SAFe DevOps Practitioner 6.0 study guide1, the Continuous Delivery Pipeline (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. The CDP enables organizations to deliver new functionality to users far more frequently than traditional processes. The first step in the CDP is Continuous Exploration, which focuses on creating alignment on what needs to be built. In CE, design thinking ensures the enterprise understands the market problem or customer need and the solution required to meet that need. It starts with a hypothesis of something that will provide value to customers. Therefore, an idea marks the beginning of the CDP in CE.
NEW QUESTION # 55
What organizational anti-pattern does DevOps help to address?
- A. Teams that are isolated and working within functional areas (e.g., business, operations, and technology)
- B. Walls of confusion between Customers and the business
- C. Too much focus on centralized planning
- D. Organizations that make decisions along functional lines
Answer: A
Explanation:
Explanation
According to the SAFe DevOps Practitioner 6.0 study guide1, one of the organizational anti-patterns that DevOps helps to address is teams that are isolated and working within functional areas (e.g., business, operations, and technology). This anti-pattern creates silos, conflicts, and inefficiencies that hinder the collaboration and integration needed for continuous delivery. For example, some teams may prioritize speed over quality, while others may prioritize security over innovation. Some teams 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, DevOps helps to break down the functional silos and enable cross-functional teams that work together to deliver value to customers faster and more reliably.
NEW QUESTION # 56
What triggers the Release activity?
- A. Change validated in staging environment
- B. Business decision to go live
- C. Successful user acceptance tests
- D. Successful deployment to production
Answer: B
Explanation:
Explanation
According to the SAFe DevOps Practitioner 6.0 study guide and handbook, the Release activity is triggered by a business decision to go live. This means that the Solution is ready to be delivered to end users and customers, based on the validation and testing done in the previous activities. The handbook states that "The Release activity is triggered by a business decision to go live."1 Therefore, this activity involves releasing value to customers on demand, while also measuring and learning from the feedback.
NEW QUESTION # 57
Which teams should coordinate when responding to production issues?
- A. SRE teams and System teams
- B. Support teams and Dev teams
- C. Dev teams and Ops teams
- D. Teams across the Value Stream
Answer: D
Explanation:
Explanation
According to the SAFe DevOps Practitioner 6.0 study guide1, when responding to production issues, the DevOps teams should coordinate with each other and with the SRE teams and System teams. The DevOps teams are responsible for developing, building, integrating, testing, deploying, and monitoring the Solution, while the SRE teams and System teams are responsible for ensuring the reliability, availability, security, and performance of the Solution in production. The Ops teams are responsible for managing the infrastructure and services that support the Solution in production. Therefore, all three groups of teams should work together to resolve production issues effectively.
NEW QUESTION # 58
Which technical practice incorporates build-time identification of security vulnerabilities in the code?
- A. Dynamic code analysis
- B. Penetration testing
- C. Threat modeling
- D. Application security
Answer: A
Explanation:
Explanation
According to the SAFe DevOps Practitioner 6.0 study guide and handbook, dynamic code analysis is a technical practice that incorporates build-time identification of security vulnerabilities in the code. This means that the code is scanned for potential security risks during the compilation or execution phase, rather than during the testing phase. The handbook states that "Dynamic code analysis is a technique that identifies security vulnerabilities in the code during compilation or execution."1 Therefore, dynamic code analysis helps teams detect and fix security issues early in the development process.
NEW QUESTION # 59
Which DevOps principle focuses on identifying and eliminating bottlenecks in the Continuous Delivery Pipeline?
- A. Recovery
- B. Lean flow
- C. Measurement
- D. Automation
Answer: B
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 # 60
What is true about the Critical Flow Properties portion of the DevOps Transformation Canvas?
- A. It captures the lowest priority improvement items
- B. It captures the work-in-process (WIP) limits that should be applied to the Value Stream
- C. It captures the people who need to improve the flow properties
- D. It captures the flow properties that are most in need of improvement
Answer: D
Explanation:
Explanation
According to the SAFe DevOps Practitioner 6.0 study guide1, the Critical Flow Properties portion of the DevOps Transformation Canvas captures the flow properties that are most in need of improvement. Flow properties are the characteristics of a value stream that affect how well it delivers value to customers. The Critical Flow Properties portion identifies the flow properties that have the most impact on customer satisfaction and business outcomes, and prioritizes improvement actions accordingly. The Critical Flow Properties portion is based on data from monitoring systems, customer feedback, and business value analysis.
Therefore, it captures the flow properties that are most in need of improvement for each value stream.
NEW QUESTION # 61
Where do features go after Continuous Exploration?
- A. Into Continuous Integration, where they are then split into Stories
- B. Into Continuous Integration, where they are deployed with feature toggles
- C. Into the Portfolio Backlog, where they are then prioritized
- D. Into Continuous Development, where they are implemented in small batches
Answer: A
Explanation:
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.
NEW QUESTION # 62
What differentiates Deployment and Release in the continuous Delivery Pipeline?
Choose the correct option from below list
- A. Deployment involves moving changes to staging; release involves moving them to productionwrong
- B. Deployment occurs multiple times per day; release occurs on demand
- C. Deployment involves moving changes to production; release involves making them available to end users
- D. Deployment occurs multiple times per day; release occurs in PI boundaries
Answer: C
Explanation:
Explanation
Continuous Deployment (CD) is an aspect of the Continuous Delivery Pipeline that automates the migration of new functionality from a staging environment to production, where it is made available for release. CD is a technical practice that enables the ability to release value at any time, in a sustainable way. CD is not the same as Release on Demand, which is the business decision to make the new functionality available to end users. Release on Demand is the final aspect of the Continuous Delivery Pipeline, which enables the delivery of value to the end user as fast as possible, based on market demand
NEW QUESTION # 63
What is one potential outcome of the Verify activity of the Continuous Delivery Pipeline?
- A. Analyze regression testing results
- B. Fix a broken build
- C. Capture usage metrics from a canary release
- D. Roll back a failed deployment
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.
NEW QUESTION # 64
How should developers integrate refactoring into their workflow?
Choose the correct option from below list
- A. Refactor continuously as part of test-driven development
- B. Create and estimate refactoring tasks for each Story in the Team Backlog
- C. Allocate a portion of their capacity to refactoring in every Iteration
- D. Create and estimate refactoring Stories in the Team Backlog
Answer: D
Explanation:
Explanation
Refactoring is the activity of improving the internal structure or operation of a code or component without changing its external behavior. The goal of software development is the continuous delivery of business value to users and stakeholders. Constantly changing technology and evolving business objectives make maintaining and continuously increasing business value difficult. Refactoring enables an emergent design, ensuring the system continues to meet future business needs. Refactors are a particular type of Enabler story in SAFe, and, like any other Story, they must be estimable, verifiable, and valuable, as well as accepted by the Product Owner. SAFe emphasizes the importance of keeping all work visible, including refactoring. Like user value work, refactoring must be planned for, estimated, and prioritized. Therefore, developers should create and estimate refactoring Stories in the Team Backlog, and work on them according to their WSJF1
NEW QUESTION # 65
Weighted shortest job first (WSJF) is applied to backlogs to identify what?
- A. Proxy for job size
- B. User business value
- C. Epics, Features, and Capabilities
- D. Relative economic value
Answer: D
Explanation:
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.

Explanation:
Explanation
According to the SAFe DevOps Practitioner 6.0 study guide and handbook, value flows through Continuous Integration in the Continuous Delivery Pipeline. This aspect involves merging code changes from multiple developers into a shared repository and running automated tests to ensure quality and functionality. The handbook states that "Continuous Integration is the process of merging code changes from multiple developers into a shared repository and running automated tests to ensure quality and functionality."1 Therefore, Continuous Integration enables teams to deliver value faster and more reliably by reducing integration errors and conflicts.
NEW QUESTION # 70
What falls outside the scope of the Stabilize activity?
- A. Continuous security monitoring is done
- B. Features are monitored after release
- C. Blue/green deployment
- D. Failover and recovery processes are in place
Answer: C
Explanation:
Explanation
Blue/green deployment falls outside the scope of the Stabilize activity. The Stabilize activity is part of the Release on Demand aspect of the Continuous Delivery Pipeline, which is responsible for releasing new functionality to end users, either immediately or incrementally, based on business and customer needs. The Stabilize activity ensures that the solution is working well from a functional and nonfunctional perspective, and that it can be operated and supported effectively. The Stabilize activity involves the following practices:
Continuous security monitoring - Applying automated tools and processes to detect and respond to security threats and vulnerabilities in the production environment, and ensuring compliance with security policies and standards.
Failover and recovery processes - Establishing and testing backup and restore mechanisms, disaster recovery plans, and business continuity procedures, to ensure the availability and resilience of the solution in case of failures or disruptions.
Features monitoring - Collecting and analyzing data on the usage, performance, and outcomes of the released features, to measure their value and impact, and to identify any issues or defects that need to be fixed or improved.
Support and maintenance - Providing ongoing support and maintenance for the solution, such as resolving incidents, handling requests, applying patches, and performing upgrades, to ensure the reliability and quality of the solution.
Blue/green deployment, on the other hand, is a technical practice that belongs to the Continuous Deployment aspect of the Continuous Delivery Pipeline, which is responsible for deploying new functionality into the production environment, where it can be tested and validated. Blue/green deployment is a change management strategy that reduces the downtime and risk of deploying new versions of software. It involves having two identical but separate environments: one is the active environment that serves the user traffic (blue), and the other is the inactive environment that hosts the new version of the software (green). The deployment process consists of switching a small portion of the user traffic from the blue environment to the green environment, after verifying that the new version is working properly. The portion of users who receive the new version are called canaries, as they serve as early indicators of the quality and performance of the new version. If the canary release is successful, the entire user traffic is gradually switched to the green environment, which becomes the new active environment. If the canary release fails, the user traffic is switched back to the blue environment, which remains the active environment. Blue/green deployment 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 active environment.
It eliminates the need for complex and error-prone migration scripts, as the inactive environment can be prepared and tested in advance, without affecting the active environment.
It enables testing and experimentation of the new version with a subset of users, by directing some user traffic to the inactive 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 # 71
Who is responsible for ensuring quality is built into the code in SAFe?
- A. Testers - xx
- B. Developers
- C. Product Owners
- D. Agile Teams
Answer: D
Explanation:
Explanation
Agile Teams are responsible for ensuring quality is built into the code in SAFe. SAFe is a framework for scaling agile practices across the enterprise, based on the principles of Lean, Agile, and DevOps. SAFe organizes the enterprise into Agile Release Trains (ARTs), which are teams of Agile Teams that deliver value in a regular cadence. Agile Teams are the fundamental building blocks of SAFe, and they are cross-functional, self-organizing, and self-managing teams that deliver value in short iterations. Agile Teams are responsible for ensuring quality is built into the code in SAFe, by applying the following practices:
Test-first - Test-first is a practice that involves writing tests before writing code, to ensure that the code meets the requirements and standards, and does not introduce any defects or vulnerabilities. Test-first helps to improve the design and maintainability of the code, and to accelerate the feedback and validation process. Test-first can be implemented using various techniques, such as Test-Driven Development (TDD), Behavior-Driven Development (BDD), or Acceptance Test-Driven Development (ATDD).
Built-in quality - Built-in quality is a practice that involves applying quality standards and checks throughout the solution lifecycle, rather than inspecting quality after the fact. Built-in quality helps to prevent defects from escaping to downstream stages or customers, and to reduce the cost and risk of rework and waste. Built-in quality can be achieved using various methods, such as code quality and security analysis, code review, pair programming, refactoring, and continuous testing.
Continuous testing - Continuous testing is a practice that involves automating and executing tests at every stage of the Continuous Delivery Pipeline, to verify that the solution meets the functional and nonfunctional requirements and standards, and to detect and resolve any issues or defects as early as possible. Continuous testing helps to ensure the reliability and performance of the solution, and to support the delivery and deployment of value to the customer. Continuous testing can be performed using various tools and frameworks, such as unit testing, integration testing, system testing, acceptance testing, performance testing, and security testing
NEW QUESTION # 72
Who is responsible for building and continually improving the Continuous Delivery Pipeline?
Choose the correct option from below list
- A. Scrum Teams
- B. DevOps Teams
- C. System Teams
- D. Agile Release Trains
Answer: D
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 # 73
What is an element of CALMR?
- A. Recovery
- B. Compliance
- C. Application security
- D. Metrics
Answer: A
Explanation:
Explanation
According to the SAFe DevOps Practitioner 6.0 study guide and handbook, recovery is an element of CALMR. This means that recovery is the ability to restore the Solution to a desired state after a failure or incident. The handbook states that "Recovery is the ability to restore the Solution to a desired state after a failure or incident."1 Therefore, recovery is one of the key aspects of DevOps excellence that enables continuous delivery.
NEW QUESTION # 74
What are two important items to monitor in production to support the Release on Demand aspect in SAFe?
(Choose two.)
- A. Business value
- B. Number of concurrent users
- C. Unit test coverage
- D. Percent Complete and Accurate (%C&A)
- E. System performance
Answer: B,E
Explanation:
Explanation
Two important items to monitor in production to support the Release on Demand aspect in SAFe are the number of concurrent users and the system performance. The number of concurrent users is the number of users who are accessing the system at the same time. It is an indicator of the demand and popularity of the system, as well as the potential load and stress on the system resources. The system performance is the measure of how well the system responds to user requests and meets the nonfunctional requirements, such as availability, reliability, scalability, and security. Monitoring the number of concurrent users and the system performance helps to support the Release on Demand aspect in SAFe by providing valuable information for the following purposes:
To optimize the release strategy and timing, based on the user behavior and preferences To ensure the system can handle the expected and unexpected user traffic, and to scale up or down the system resources as needed To detect and resolve any issues or incidents that may affect the user experience and satisfaction To evaluate the impact and value of the released features, and to identify areas for improvement or innovation 5
NEW QUESTION # 75
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 as often as possible and release when the business needs it
- C. To deploy to production multiple times per year and release on a cadence once or twice a year
- D. To deploy to production and release at least once every Program increment
Answer: B
Explanation:
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
