We had a little chat with our top IT Professional Mentors. They had some insights on the Top Interview Questions for DevOps Professionals. They conduct DevOps Training in Pune with Ethans Tech. Read on to know more about what kind of questions are asked in the technical interview. What is DevOps? In simple language, DevOps is a set of practices that combines software development and IT operations. This means it is a perfect blend of Development & Operations. It aims to shorten the system’s development life cycle and also provide continuous delivery with high software quality. DevOps is complementary to Agile software development. Several DevOps concepts have come from the Agile methodology. If you are someone who is looking forward to a wonderful career, Ethans Tech provides a DevOps course with placement in Pune. You can book a free session to gain in-depth knowledge about DevOps. Here are some top interview questions for DevOps Engineer [These questions are for beginner and intermediate level candidates] What do you think is the role of a DevOps Engineer? A DevOps engineer works with IT staff and software developers to ensure smooth code releases. In other words, DevOps engineers understand the Software Development Lifecycle and the automation tools used in CD/CI pipelines. DevOps is extremely beneficial in achieving frequent deployment deployments, quick bug fixes, quick release failure recovery, and much more. Because of its numerous advantages, most multinational corporations have adopted this methodology to improve organizational performance. Why is SSH used? SSH, which stands for Secure Shell, is an administrative protocol that allows users to access and control remote servers over the Internet via the command line.  SSH is a secure encrypted version of Telnet, which was previously unencrypted and insecure. This ensured that communications with the remote server were encrypted. SSH also includes mechanisms for remote user authentication, input communication between the client and the host, and output delivery back to the client. What do you understand by Configuration Management? Configuration management (CM) is essentially the practice of handling changes in such a way that the system does not lose its integrity over time. This includes policies, techniques, procedures, and tools for evaluating, managing, and tracking change proposals, as well as maintaining appropriate documentation. CM contributes administrative and technical guidance to the appreciation’s design and development. Describe the different phases in DevOps DevOps Plan – In the very beginning, a plan for the type of application that needs to be developed should be created. Having a general idea of the development process is always a good idea. Code – The coding of the application is done to meet the requirements of the end user. Build – We then create the application by combining the various codes developed in the previous steps. The most important step in the development of an application is testing. If necessary, test the application and rebuild it. Integrate – Multiple codes from various programmers are combined into one.  Deploy – The code is placed in a cloud environment for later use. It is ensured that any new changes do not interfere with the operation of a high-traffic website. If necessary, operations are performed on the code. Monitor- Application performance is monitored. Changes are finally made to meet the requirements of the end-user What is the full form of CAMS? What does it represent?  CAMS stands for Culture, Automation, Measurement, and Sharing. It embodies the essence of DevOps. What is CI and why is it useful? Continuous Integration (CI) is the process of compiling the entire code base into the shared source code repository every time a member of the software development team checks the code. If a team member checks in a bugged code file, the build is broken. Other developers cannot synchronize the shared source code repository in this case without introducing compilation errors into their local workspaces. As a result, collaborative and shared software development is doomed. When a CI build fails, the issue must be resolved as soon as possible. A CI process frequently includes a suite of unit, integration, and regression tests that are executed whenever the compilation succeeds. If the tests fail, we consider the build unstable, and not broken. These were some of the questions that will help you get a better understanding of the type of questions to come. You can enroll with us to gain a deeper understanding. Ethans is one of the best DevOps Training Institutes in Baner and Kharadi. At Ethans Tech, you learn from the experts.

Before you decide to pursue a career in DevOps, here are some things you should consider. What is DevOps? DevOps is a combination of development and operations, as the name implies. Because of their agile nature, DevOps applications in software development have gained widespread attention. DevOps contributes to the establishment of a clear relationship between IT operations and development. DevOps’ primary goal is to strengthen the relationship between development and IT operations. DevOps places a strong emphasis on advocating for improved collaboration and communication. The first thing you should concentrate on is learning about DevOps. Of course, you can also take up DevOps Course in Pune from Ethans Tech to get an Advance Certification Training Program in DevOps from industry experts. DevOps aims to capitalize on these advancements to deliver high-quality software with increased speed and reliability. DevOps can also be thought of as an automation process for rapid and secure software development. Why are people leaning towards a career in DevOps? Many IT professionals prefer a DevOps career because of the enormous potential for long-term growth and adoption. However, many people lack clarity before embarking on a career in DevOps. Many of you already in the technical or IT industry are aware of how DevOps is revolutionizing software development and deployment in businesses by eliminating conflicts between development and operations teams – one of the most significant challenges that businesses have faced for a long time. Companies that implement DevOps practices simply get more done faster. Implementing a successful DevOps strategy enables organizations to deliver software solutions quickly. This, in turn, aids in preventing and resolving production issues, resulting in a better customer experience, feedback, and communication.  What are some of the DevOps Tools? DevOps operates in a cross-functional mode, involving multiple tools of various types and purposes rather than just one. As previously discussed, these tools are also referred to as DevOps toolchains. The tools aid in all stages of the software development lifecycle, including development, management, and delivery. DevOps organizations coordinate these tools and integrate them into one or more productive activities such as planning, creation, verification, packaging, releasing, configuring, monitoring, and version control. Jenkins has over 100 plugins that allow it to integrate with almost every tool in the CI/CD toolchain, including Git, Amazon EC2, Maven, and others. It is a self-contained Java program that runs on major platforms such as Windows, macOS, Linux, and Unix. Jenkins’ simple web interface with built-in error checks helps make it simple to set up and configure. Docker delivers applications in packages known as containers by utilizing OS-level virtualization. It separates these containers and bundles the software, configuration files, and libraries, making them more transferable and secure. It easily integrates with GCP and AWS and simplifies cloud migration. Docker makes distributed development easier. Python, PowerShell, Java, Ruby, Go, C/C++, and Bash are some notable scripting languages. You should also improve your skills and knowledge of cloud computing resources such as AWS or Azure. Another notable skill for a DevOps career is the use of containers. The use of tools like Docker and container orchestration platforms like Kubernetes is required. You can also learn more about both of these by comparing Chef and Puppet. Other tools like Apache Maven, and Gradle. Get proof of your technical skills through certification: Certifications can help ease the process of getting placed. Certifications also help in filling the knowledge gaps in your skills. You can reinvent your career by adding DevOps certification to your resume. DevOps professionals also earn well. The easiest way to get certification is to take up DevOps Course in Pune. DevOps Certification will also improve you in an overall sense. Being in a class with a room full of professionals will promote building other soft skills which are in high demand these days.
