DevOps is a:
Correct Answer
A. Culture
Explanation
DevOps is not just a role or a team, but rather a culture that promotes collaboration, communication, and integration between development and operations teams. It emphasizes the importance of breaking down silos and fostering a shared responsibility for delivering high-quality software. The culture of DevOps encourages automation, continuous integration, and continuous delivery, as well as the adoption of various tools and practices to streamline the software development and deployment processes.
2.
Removing unplanned work is a key principle of DevOps.
Correct Answer
A. True
Explanation
Removing unplanned work is a key principle of DevOps because it focuses on streamlining processes and eliminating unnecessary tasks. By identifying and addressing issues proactively, teams can reduce the amount of unplanned work that arises, allowing them to focus on delivering value and improving efficiency. This principle aligns with the overall goal of DevOps, which is to foster collaboration, automation, and continuous improvement in order to deliver high-quality software products efficiently.
3.
The origins of DevOps trace back to when:
Correct Answer
A. 2009
Explanation
The correct answer is 2009 because this is the year when the term "DevOps" was coined at the Agile Conference in Toronto. The concept of DevOps emerged as a response to the need for collaboration and communication between software developers and IT operations teams to improve the software development and deployment process. It gained popularity in the following years as organizations recognized the benefits of breaking down silos and integrating development and operations.
4.
The following is a fair statement about DevOps:
"The goal of DevOps is not just to increase the rate of change but to successfully deploy features into production without causing chaos and disrupting other services."
Correct Answer
A. True
Explanation
This statement accurately describes the goal of DevOps. DevOps aims to streamline the software development and deployment process, ensuring that new features and updates can be implemented smoothly without causing disruptions or chaos to other services already in production. It emphasizes the importance of balancing speed and stability, ultimately aiming for successful deployments that do not negatively impact the overall system.
5.
Which of these is not a principle of DevOps?
Correct Answer
A. Rewarding firefighting
Explanation
Rewarding firefighting is not a principle of DevOps because DevOps focuses on preventing and minimizing firefighting situations through automation, collaboration, and continuous improvement. The goal of DevOps is to create a culture of proactive problem-solving and continuous delivery, rather than rewarding reactive responses to issues. DevOps principles include resilient engineering, amplifying feedback loops, and reduction of technical debt, which all contribute to a more efficient and stable software development and delivery process.
6.
Which of these statements are true?
Correct Answer
D. All of the above
Explanation
The correct answer is "All of the above". This means that all three statements are true. DevOps aims to extend the Dev (Development) phase into Production, embed Development into IT Operations, and embed IT Operations into Development. This approach promotes collaboration and integration between different teams involved in software development and deployment, leading to improved efficiency and quality in the software development lifecycle.
7.
Amazon claims to do over 1000 deploys per day.
Correct Answer
A. True
Explanation
Amazon claims to do over 1000 deploys per day. This means that Amazon is able to release new updates, features, and fixes to their systems and services at a rapid pace. Doing over 1000 deploys per day demonstrates a high level of agility and efficiency in their software development and deployment processes. It also suggests that Amazon is constantly working on improving their services and providing the best possible experience for their customers.
8.
DevOps and ITIL have nothing in common.
Correct Answer
B. False
Explanation
DevOps and ITIL actually have several things in common. Both DevOps and ITIL aim to improve the efficiency and effectiveness of software development and deployment processes. They both focus on collaboration and communication between different teams and stakeholders. While DevOps emphasizes continuous integration and delivery, ITIL focuses on service management and aligning IT services with business needs. Both approaches also prioritize automation and the use of metrics and feedback to drive improvements. Therefore, the statement that DevOps and ITIL have nothing in common is false.
9.
Which benefits of adopting a DevOps approach could be a part of a business case for adopting a DevOps approach?
Correct Answer
E. All of the above
Explanation
Adopting a DevOps approach can bring several benefits to an organization. Improved deployment frequency allows for faster time to market, enabling the organization to release new features or products more quickly. A lower failure rate of new releases means that the organization can deliver higher-quality software with fewer bugs or issues. Shortened lead time between fixes ensures that any problems can be addressed and resolved more efficiently. Finally, a faster mean time for recovery in the event of a new release crashing or disabling the system minimizes downtime and ensures business continuity. Therefore, all of the mentioned benefits can be part of a business case for adopting a DevOps approach.
10.
Which of the following statements best describes the role of Change Management in a DevOps environment?
Correct Answer
A. The moment an app change is asked for, the request should go out to everyone on the team, no matter which IT discipline they work in.
Explanation
In a DevOps environment, the best role for Change Management is to ensure that the request for an application change is communicated to everyone on the team, regardless of their IT discipline. This approach promotes collaboration and transparency among team members, allowing them to collectively assess the impact and feasibility of the requested change. By involving all team members, the organization can leverage diverse expertise and perspectives to make informed decisions and implement changes effectively. This inclusive approach aligns with the principles of DevOps, which emphasize collaboration and shared responsibility across different roles and functions.
