Scaled Agile SAFe DevOps Practitioner Exam SDP (6.0) SAFe-DevOps Exam Practice Test

Answer : B

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

Answer : B

Under the Respond activity in the context of DevOps, the practice of Rollback is often included. Rollback is a key response mechanism used to quickly revert a system to a previous stable state in the event of a failure or issue in the production environment. This practice is critical for maintaining system stability and minimizing downtime.

Answer : A, E

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

Answer : D

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.

Answer : E

After the team maps the steps of the current state value stream during value stream mapping, the next two steps are to measure the performance at each step and calculate the activity ratio. Measuring the performance at each step involves collecting data on cycle time, lead time, process time, wait time, defect rate, and other relevant metrics. This helps to identify the sources of waste, delays, and inefficiencies in the value stream. Calculating the activity ratio involves dividing the total process time by the total lead time and multiplying by 100. This gives the percentage of time that is spent on value-adding activities versus non-value-adding activities.The activity ratio helps to quantify the flow and identify opportunities for improvement

Answer : D

According to the SAFe DevOps Practitioner 6.0 study guide and handbook, specific improvements to the Continuous Delivery Pipeline are identified in Future-state Value Stream Mapping. This activity involves envisioning and designing the ideal state of the value stream, based on the current state and the desired outcomes.The handbook states that 'Future-state Value Stream Mapping is a way of defining how you want your value stream to look like in the future.'1Therefore, Future-state Value Stream Mapping helps teams identify and prioritize the areas that need improvement in their Continuous Delivery Pipeline.

Answer : B

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.
