QUESTION: 17

Which statement illustrates the biggest bottleneck?

WT = 5 days, AT = 2.5 days, %C&A = 100%
WT = 10 days, AT = 0.5 day, %C&A = 100%
WT = 1 day, AT = 0.5 day, %C&A = 90%
WT = 6 days, AT = 5 days, %C&A = 100%

Answer(s): B

Explanation:

According to the SAFe DevOps Practitioner 6.0 study guide and handbook, the statement that illustrates the biggest bottleneck is B. WT = 10 days, AT = 0.5 day, %C&A = 100%. This means that the value stream has the longest lead time (WT), the shortest actual time (AT), and the highest relative economic value (C&A). These are the three metrics that are used to measure and optimize the value stream performance. The handbook states that "The three metrics used to measure and optimize value stream performance are WT, AT, and %C&A."1 Therefore, a bigger bottleneck indicates a lower value stream efficiency and a higher waste or inefficiency.

QUESTION: 18

The DevOps Health Radar aligns the four aspects of the Continuous Delivery Pipeline to which four stakeholder concerns?

Portfolio, Solution, ART, team
Productivity, efficiency, speed-to-market, competitive advantage
Exploration, integration, development, reflection
Alignment, quality, time-to-market, business value

Answer(s): D

Explanation:

The DevOps Health Radar aligns the four aspects of the Continuous Delivery Pipeline to four stakeholder concerns: alignment, quality, time-to-market, and business value. The DevOps Health Radar is a tool that helps Agile Release Trains (ARTs) and Solution Trains assess their ability to Release on Demand, which is the process of delivering value to customers whenever there is a business need. The DevOps Health Radar consists of four dimensions that correspond to the four aspects of the Continuous Delivery Pipeline: Continuous Exploration (CE), Continuous Integration (CI), Continuous Deployment (CD), and Release on Demand. Each dimension has four sub- dimensions that reflect the key practices and capabilities that enable the flow of value. The DevOps Health Radar helps the ARTs and Solution Trains to measure their maturity in each sub-dimension, using a scale of Sit, Crawl, Walk, Run, or Fly. The DevOps Health Radar also helps the ARTs and Solution Trains to identify the gaps and improvement opportunities in their DevOps practices, and to prioritize the next steps toward achieving higher levels of maturity. The DevOps Health Radar aligns the four aspects of the Continuous Delivery Pipeline to four stakeholder concerns, as shown in Figure
1:
Alignment Alignment is the concern of ensuring that the solution is aligned with the customer needs, market opportunities, and strategic goals of the enterprise. Alignment is achieved by applying the CE aspect, which involves exploring the market and customer problems, defining a vision, roadmap, and set of features for the solution, and validating the assumptions and hypotheses with customer feedback and data.
Quality Quality is the concern of ensuring that the solution meets the functional and nonfunctional requirements and standards, and that it does not introduce any defects or vulnerabilities. Quality is achieved by applying the CI aspect, which involves developing, testing, integrating, and validating new functionality in preparation for deployment and release. Time-to-market Time-to-market is the concern of ensuring that the solution can be delivered and deployed to the production environment as fast and as frequently as possible, without compromising quality or security. Time-to-market is achieved by applying the CD aspect, which involves automating and streamlining the deployment process, and ensuring the stability and reliability of the production environment.
Business value Business value is the concern of ensuring that the solution delivers the expected outcomes and benefits to the customer and the enterprise, and that it can be adapted and improved based on the changing needs and feedback. Business value is achieved by applying the Release on

Demand aspect, which involves releasing new functionality to the customer incrementally or immediately, based on the market demand, and measuring and learning from the results12

QUESTION: 19

Which metric reflects the quality of output at each step in the Value Stream?

Code quality
Active Time
Percent Complete and Accurate (%C&A)
Flow Efficiency

Answer(s): C

Explanation:

According to the SAFe DevOps Practitioner 6.0 study guide and handbook, the metric that reflects the quality of output at each step in the Value Stream is Percent Complete and Accurate (%C&A). This metric measures the relative cost of delay divided by the relative job duration, which indicates how efficiently the value stream delivers value to customers. The handbook states that "Percent Complete and Accurate (%C&A) is a metric that measures the relative cost of delay divided by the relative job duration."1 Therefore, %C&A helps teams identify and eliminate any waste or inefficiencies in their value stream.

QUESTION: 20

Which practice helps developers deploy their code into production?

Deployment automation
Continuous Deployment
Infrastructure as code
Self-service deployment

Answer(s): B

Explanation:

According to the SAFe DevOps Practitioner 6.0 study guide and handbook, Continuous Deployment is a practice that helps developers deploy their code into production. This means that Continuous Deployment involves moving changes from the staging environment to the production environment, without requiring manual intervention or approval. The handbook states that "Continuous Deployment is the practice of moving changes from the staging environment to the production environment, without requiring manual intervention or approval."1 Therefore, Continuous Deployment enables teams to deliver value to customers faster and more reliably.
