Introducing DevOps

Question 1

What is DevOps?

Answer 1

A mindset, a culture, and a set of technical practices. It
provides communication, integration, automation, and close
cooperation among all the people needed to plan, develop, test,
deploy, release, and maintain a Solution.

Question 2

What is a critical goal of DevOps?

Answer 2

Building Alignment

Question 3

To deliver value whenever there is a business need Is the goal of the

Answer 3

Continuous Delivery Pipeline (CDP)

Question 4

Some of DevOps benefits are:

Answer 4

1. More Frequent Deployment Frequency
2. Faster Lead Time
3. Faster Time to Restore Service

Question 5

What is the SAFe DevOps Health Radar?

Answer 5

A tool that helps ARTs and Solution Trains optimize their value stream performance. It provides a holistic DevOps health check by assessing the maturity of the four aspects and 16 activities of the continuous delivery pipeline. The Health Radar is used to measure baseline maturity at any point in a DevOps transformation and guide fast, incremental progress thereafter.

Question 6

The Continuous Delivery Pipeline(CDP) accelerates….

Answer 6

Value Flow

Question 7

What are the four aspects of the Continuous Delivery Pipeline (CDP)?

Answer 7

1. Continuous Exploration
2. Continuous Integration
3. Continuous Deployment
4. Release on Demand

Question 8

What is the role of Continuous Security?

Answer 8

Continuous Security emphasizes practices such as security by design, threat modeling, security-as-code, as well as automation in the areas of vulnerability scanning, penetration testing, and intrusion detection.

Question 9

What are the DevOps Practice Domains?

Answer 9

1. Deployment Pipeline
2. Configuration Management
3. Version Control
4. Continuous Security
5. Continuous Quality
6. Value Stream Management

Question 10

What is the role of Continuous Testing?

Answer 10

Build quality into Solutions by testing early and often

Question 11

What is SAFe’s CALMR approach to DevOps?

Answer 11

A mindset that guides ARTs toward achieving continuous value delivery by managing simultaneous advancements in delivery culture, automation, lean flow, measurement, and recovery.

Question 12

When everyone in the value stream thinks and acts with continuous delivery in mind, the result is…

Answer 12

1. Increased frequency, quality, and security of product innovation
2. Decreased deployment risk with accelerated learning cycles
3. Accelerated solution time-to-market
4. Improved solution quality and shortened lead time for fixes
5. Reduced severity and frequency of failures and defects
6. Improved Mean Time to Recover (MTTR) from production incidents

Question 13

Which CALMR approach establishes a culture of shared responsibility for development, deployment, and operations?

Answer 13

Culture

Question 14

Automating the Continuous Delivery Pipeline is which part of the CALMR approach to DevOps?

Answer 14

Automation

Question 15

Which CALMR approach keeps batch sizes small, limit WIP, and provide extreme visibility?

Answer 15

Lean Flow

Question 16

Which CALMR approach measures the flow through the pipeline and implements full-stack
telemetry?

Answer 16

Measurement

Question 17

What is Recovery in the CALMR approach?

Answer 17

Architect and enable low-risk releases. Establish fast recovery, fast reversion, and fast fix-forward.

Question 18

In the CALMR approach, culture requires:

Answer 18

1. Customer-centricity
2. Collaboration
3. Risk Tolerance
4. Knowledge Sharing

Question 19

The three keys to accelerating flow are:

Answer 19

2. Reduce batch sizes
3. Manage queue lengths

Question 20

What measurements should be tracked in the CDP?

Answer 20

1. measure pipeline flow
2. measure solution quality
3. measure solution value

Question 21

What techniques support fast recovery?

Answer 21

1. stop the line mentality
2. plan for and rehearse failures
3. fast fix forward and roll back
