devops

There are many reasons for an organization to become interested in DevOps. When should companies become interested in DevOps?

• When Agile practices do not seem to fit the organization

• When no other method gives the necessary results

• When Scrum and Lean practices have been implemented

Which requirements should a DevOps team take into account when working on a backlog item?

• Both non-functional and functional requirements

• Neither non-functional nor functional requirements

• Only functional requirements

• Only non-functional requirements

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 requirement is Done when it has been built.

• A requirement is Done when it has been tested.

• A requirement is Done when the product is accepted.

• A requirement is Done when the product is in Production.

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?

• 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.

• Because enabling measurements of the key indicators in the value stream is done incorrectly or inefficiently, which leads to problems.

• 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.

• 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.

• Because when the traditional approach is still used, it requires many decisions to be made before work even starts, which causes massive delays.

Why is the concept 'value stream' so important in DevOps?

• The value stream helps employees to see and understand their daily tasks

• The value stream helps to analyze the as-is map and any attempts to improve metrics.

• The value stream helps to identify when someone did their part of the work

• The value stream helps to realize a smooth and uniform flow through all process steps.

• The value stream helps to realize local optimization in the current work practice.

Which idea is the origin of the concept 'deployment pipeline'?

• A pipeline that carries a liquid creating flow

• An assembly line such as a car plant

• Modern processors that use parallel pipelining

• The idea of using more than one assembly line

• The process of deploying people to do different jobs

For DevOps, finding the balance between moving quickly and maintaining application reliability is important. How does version control support this?

• By allowing any member of the team to freely delete unnecessary files and documents

• By allowing the formation of small independent and self-sufficient development teams

• By applying specialized tools to eliminate or reduce waste and optimize processes

According to the US National Institute of Standards and technology (NIST), what is not an essential cloud computing characteristic?

• Broad network access

• Pay-per-use system

• Rapid elasticity

• Resource pooling

In DevOps, what should be done when process deficiencies are found?

• All changes should be submitted to a backlog, so they can be released in a project or a Kaizen event.

• Fixes must be found and implemented as soon as possible after detection of the deficiency.

• Fixes must be found, approved by the change manager, and released based on priority.

• Fixes must be found, approved by the continuous improvement manager, and released immediately

• Fixes should be postponed until the change can be included in an appropriate sprint.

A value stream map shows clearly where the inefficiencies in a value stream are. Why should a value stream map be made?

• To help optimize business processes

• To see which people are not working hard enough

• To speed up the Work-in-Progress (WiP)

• To visualize which product line should be ended
