01. Why is the concept 'value stream' so important in DevOps?
a) The value stream helps coworkers to see and understand their daily tasks.
b) The value stream helps to analyze the as-is map and any attempts to improve metrics.
c) The value stream helps to identify when someone did their part of the work.
d) The value stream helps to realize a smooth and uniform flow through all process steps.
e) The value stream helps to realize local optimization in the current work practice.
02. A value stream map shows clearly where the inefficiencies in a value stream are. Why should a value stream map be made?
a) To help optimize business processes
b) To see which people are not working hard enough
c) To speed up the Work-in-Progress (WiP)
d) To visualize which product line should be ended
03. A clear Definition of Done is critical in DevOps and considers the value for the customer. What is a good description of Done for DevOps?
a) A requirement is Done when it has been built.
b) A requirement is Done when it has been tested.
c) A requirement is Done when the product is accepted.
d) A requirement is Done when the product is in Production.
04. In DevOps, what should be done when process deficiencies are found?
a) All changes should be submitted to a backlog, so they can be released in a project or a Kaizen event.
b) Fixes should be found, approved by the change manager, and released based on priority.
c) Fixes should be found, approved by the continuous improvement manager, and released immediately.
d) Fixes should be postponed until the change can be included in an appropriate iteration.
e) Fixes should be found and implemented as soon as possible after detection of the deficiency.
05. When can the use of DevOps for organizational and technological changes lead to chaos and loss of control?
a) When the core business of the organization highly depends on information technology
b) When the organization is complex and wants to solve chronic problems
c) When the organization requires rapid changes to test new business ideas
d) When the rate of change in the information technology used by the organization is high
06. It is recommended that organizations customize and select DevOps practices that work in that organization. Organization-specific questions must be raised and organization-specific answers must be found. Why is this a good idea?
a) Because DevOps publications do not always reflect reality and underreport difficulties and failures.
b) Because that is the way to become a DevOps engineer that can be hired for implementing DevOps.
c) Because the management teams know best how to implement DevOps in their own organization
d) Because there are too few publications and events about DevOps to form independent opinions.
07. According to the US National Institute of Standards and technology (NIST), what is not an essential cloud computing characteristic?
a) Broad network access
b) Pay-per-use system
c) Rapid elasticity
d) Resource pooling
08. Tasks need to be prioritized. This prioritization takes place in the queue at the entry of the value stream. Why does this prioritization often cause problems?
a) Because at this point, the decision is made how to build the deployment pipeline for the tasks that can be automated. This takes time, which causes delays.
b) Because enabling measurements of the key indicators in the value stream is done incorrectly or inefficiently, which leads to problems.
c) Because implementation of the use of visualization tools along with WiP-limits, with which one can identify the bottlenecks of the tasks, is done incorrectly.
d) Because the development of the as-is version and the to-be version of the stream must be created, as well as a list of the changes required. This takes a lot of time.
e) Because when many decisions are made before work even starts, like in the traditional approach, this causes massive delays.
09. Which requirements should a DevOps team consider when working on a backlog item?
a) Only non-functional requirements
b) Only functional requirements
c) Both non-functional and functional requirements
d) Neither non-functional nor functional requirements
10. DevOps relies heavily on the principles and practices of Lean Production. One of the types of waste in IT is 'task switching'. From which original type of waste is this the translation for IT?
a) Motion
b) Overproduction
c) Waiting
d) Transportation
