You’re seeking for a DevOps-related career and/or an organizational role in an IT company, aren’t you? DevOps is the most popular and successful technology in the world, and according to a Forrester Research survey, more than half of all firms are using DevOps. Job opportunities in the field are expanding, and the compensation for DevOps professionals is quite lucrative. The average annual compensation for DevOps professionals is between $136,300 and $137,300. In other words, how well prepared are you to respond to all of the DevOps Interview Questions?
Attempting to pass the DevOps interview, on the other hand, is difficult and requires much preparation. As a resource, we’ve compiled the most comprehensive collection of DevOps Interview Questions and Answers created by industry experts. They will undoubtedly assist you in acing your DevOps job interview.
- What level of knowledge do you have about DevOps?
Clarity and understandability are essential in your answer. First, discuss how DevOps is becoming more important in the IT business. Discuss how a plan like this may assist to synergize the strategies of the production and operations teams in order to increase digital product distribution while maintaining a low failure rate. Discuss how DevOps Certification is a value-added process in which architecture and operation engineers cooperate throughout the lifespan of a product or service, from the design phase to the implementation phase, and how it may benefit your organization.
- Describe Continuous Integration in detail.
The importance of continuous integration in the Agile process is become more apparent every day. Developers often work on functionality or user experiences during a sprint, and they submit their version control repository updates to the overall effort.
The build is performed on a regular basis, based on the check-in or schedule, if the code has been committed. The developers’ complete job is carefully structured if the code has been committed. The creator must blend their modifications with those of the others in order to gain early feedback as a result of continuous integration.
- Provide an explanation of Continuous Delivery in your own words.
In the context of Continuous Development, Continuous Delivery is a technique that seeks to provide the functionality developed by developers to end-users as rapidly as feasible. During this process, it passes through many steps of quality assurance, planning, and so on, before being sent to the manufacturing system for distribution.
- Explain What exactly is Docker?
Another often requested DevOps interview question is regarding Docker and related subjects, which is another of the most frequently asked. It is a containerization strategy that gathers all of the technologies in the form of vessels in order to process applications more efficiently.
- What’s the difference between Continuous Delivery and Continuous Deployment, and how do they differ?
Consider the following scenario: a number of apps or user stories are developed, tested, and ready to be implemented during an Agile Sprint (for example). However, depending on the objectives and goals of the customer, not every suggestion will be executed. However, it is critical that the code remains easily available for distribution in this continuous delivery environment.
Continuous Deployment is a process in which all of the enhancements produced by the developer pass through several phases before being deployed in an automatic method into the PRODUCTION environment by sprintzeal.
- What is the DevOps toolchain and how does it work?
A collection of technologies is linked together to form a DevOps toolchain, which automates processes such as software development and distribution. Manual DevOps may be accomplished in a few simple steps. The demand for automation increases exponentially as the complexity of a system increases, and automation of the toolchain is required for continuous delivery to be successful. A Version Management System (VMS) is a system that keeps track of changes to software versions. GitHub is the most important component of a DevOps toolchain.
- What is the aim of configuration management in the context of DevOps and how does it help?
Various structures may be controlled and altered with the use of configuration management software. In this way, it standardizes service arrangements, which in turn allows it to oversee the IT infrastructure. It supports with numerous server maintenance and administration tasks, as well as ensuring the overall integrity of the network.
- Is DevOps considered to be a component of Agile methodology?
Although DevOps is included in agile methodology, it can only be used in conjunction with the growth element of the approach, which is the most significant distinction. Agile will be utilized for both procedures and enhancements at the same time, according to the plan.
- Discuss what configuration management is and a few prominent tools that are utilized in the process.
When we talk about configuration management, we are referring to the activities and various approaches that are employed in automating the distribution procedures and facilities. It is essential to have the server prepared for device deployment (for example, by downloading device packages and configuring the network) until the platform is completed in order to avoid delays. Because the applications are supplied, the Ops or System Administrator is responsible for maintaining consistency across numerous environments (Dev, QA, PROD, etc.)
