Nodes use the Chef client to ask the Chef server for configuration details, such as recipes, templates, and file distributions. A) Chef is a configuration management tool for dealing with machine setup on physical servers, virtual machines and in the cloud. Many companies use Chef software to control and manage their infrastructure including Facebook, Etsy, Cheezburger, and Indiegogo. There you go, these are some of the most common DevOps interview questions that you might come across while attending an interview. In addition, you must also have a holistic understanding of the products, services, and systems in place.

The DVCS does not require a centralized server to store the repository, as is the case with a centralized version control system such as Subversion. For this reason, candidates should have a basic understanding of what a playbook is and how it works. Forks allow you to separate sensitive, risky, or innovative changes from the source codebase. A fork creates a new copy of the code repository, including branches, commits, and files. A fork seems to be a cloned repository that has been pushed to a new, empty repository. Once you’ve established a fork, you can’t exchange fork files or branches with the original codebase unless you use a pull request.

In addition, administrators can use SSH to create secure tunnels for other application protocols. As part of that understanding, candidates should be able to differentiate between a Chef cookbook and recipe. The employment market is highly competitive, and interview questions for DevOps engineers can cover a wide range of topics. If you’ve begun preparing for development and operations responsibilities in the IT business, you’re already aware that it’s a challenging profession to break into. Here are some of the most frequently asked DevOps interview questions and answers to help you prepare for DevOps engineer jobs in the industry. Chef in DevOps is a configuration management tool that is recently competing with Puppet.

• Memcached is a distributed memory object caching open-source technology.
• It includes features such as dashboards, reporting, scrum, and kanban.
• Get Resume Preparations, Mock Interviews, Dumps and Course Materials from us.
• Secure Shell can also refer to the suite of utilities that implement the SSH protocol.
• Kitchen runs tests against any combination of platforms using any combination of test suites.
• The second Recipe configures the service and then ensures the package is installed.

Software teams will often look for the “fair weather” path to system completion; that is, they start from an assumption that software will usually work and only occasionally fail. I believe to practice defensive programming in a pragmatic way, which often means assuming that the code will fail and planning for those failures. I try to incorporate unit test strategy, use of test harnesses, early load testing; network simulation, A/B and multi-variate testing, etc. The resources that can be requested using the HTTP protocol, are made available using a certain type of URI (Uniform Resource Identifier) called a URL (Uniform Resource Locator). TCP (Transmission Control Protocol) is used to establish a connection to the application layer port 80 used by HTTP.

Make sure to bring across that you are familiar with Agile application lifecycle management techniques and tools. Chef server is the central hub for storing all the data needed for configuration of the nodes. The Chef Workstation is the host accountable for modifying cookbooks and configuration https://remotemode.net/blog/contract-vs-full-time-employment-comparison/ data. The workstation forwards cookbooks and configuration data to the Chef server. To create the required configuration files in Chef, starter kids are necessary. It helps to define the clear information for each configuration file and easy interaction with the server.

This ensures that developers are delivering code that doesn’t have any errors and is of high quality, and it also helps everyone leverage their time most effectively. I would resort to CI, release management, and other tools to keep interdisciplinary projects on track. It is a powerful automation platform that provides a way to transforms infrastructure into code. Questions in this category focus on the processes and tools used to support application development and delivery. With these types of questions, there is typically a strong emphasis on the CI/CD pipeline. The concept of shifting left in DevOps is based on the idea that the application development and delivery process can be graphically represented as a workflow that moves from left to right.

Both DevOps and Agile strive for quicker software delivery, yet they are fundamentally different. DevOps is a workplace culture that brings IT Ops and development together to remove roadblocks to faster product delivery. Agile methodology is a pure technique that emphasizes quick, small, incremental, and iterative software releases with a built-in feedback loop for customers. It eliminates most of the customer’s blind spots in the development process and better aligns the product with the requirements. DevOps is a methodology that brings together IT operations and the development team to deliver high-quality software products faster.
