Interview Questions FAQ

1) What is DevOps?

DevOps is a transformational development strategy that is adopted to remove the clumsiness between traditional development and operations. Without sacrificing the quality of the product delivered, it seeks for an increased speed of application delivery. DevOps removes development constraints, implements automation and creates a feedback loop from operations to the development team. In simple terms, DevOps is a mindset to deliver applications quickly with no compromise in quality.

3 Pillars to support the principles of DevOps Development:

  • Deliver Business Value predictably and incrementally.

  • Utilize proven technologies and patterns.

  • Apply appropriate rigor.

2) What are the Advantages of using DevOps?

In the DevOps model, development takes place in small and frequent development cycles based on sprint size that are likely to end in two to four weeks; so that any changes in business needs can be easily incorporated into the upcoming sprint.

In the DevOps approach, much of the solution is composed using existing reusable APIs, reliable third party services, etc. This helps in reducing the development time by making the most of the new code, required only in integration and customization.

3) What is Extreme Programming (XP)?

Extreme Programming commonly referred to as XP is one of the most popular agile methodologies, which executes software development.  XP rules are designed to focus more on customer satisfaction.  It empowers developers to respond confidently to requirement changes through smaller iterations. XP emphasizes teamwork as managers, customers and developers work as equal partners in a collaborative team. Most of the companies use XP in their DevOps Journey.

4) What is Pair Programming?

Pair programming is one of the engineering practices of Extreme Programming rules. In this practice two programmers work on one computer, on the same design/algorithm/code/test.

One programmer acting as a “driver”, and the other acting as an “observer” who continuously watches/monitors to identify problems. Both roles can be exchanged at any point of time without any handoff.

5) What are the advantages of Pair Programming?

Pair Programming helps in raising discussions from two different points of view, which in turn help in increased understanding of code/algorithm/design/test.

6) What is Test Driven Development (TDD)?

Test Driven Development is one of the core agile and DevOps practices, which is more helpful in quick iterations and continuous integrations. In this method, test cases become the key to development process. This method ensures that problems are identified quickly, which helps manage risk elegantly.

TDD is a practice where you write code to address a failing test case. It is not only considered as a testing methodology, but also as a design and development methodology.

TDD starts with taking customer requirements, writing test cases and running the code against test cases. Test Cases fail as there is no code to address the test scenario; then, you write a simple code to PASS the test case.

7) What are the advantages of Test Driven Development?

As TDD first starts with the test case, the quality of code is increased as there will be one or more test cases for all the functionalities.

  • Refactoring code can be done confidently.

  • Eventually, the complete code in your application is well tested; since, it is constructed to address all the test cases.

  • Code turns more modular and flexible as developer is addressing all the test cases by coding in smaller units.

Note: TDD is only as good as its tests. If the tests are not reflecting the requirements, code cannot reflect the requirements.

To know more about Test Driven Development, you can refer to-

‘Test Driven Development: A Practical GUIDE – David Astels.’

8) What is a build?

Build is a process in which the source code is put together to verify whether it works as a single unit. In the process of build creation or generation, the source code will undergo compilation, testing, inspection and deployment. Usually, build generation process is completely automated in a way that a single command does everything.

9) What is Continuous Integration?

Continuous delivery is an important aspect to be understood when it comes to DevOps. On the path to Continuous delivery, Continuous Integration is a critical step. Continuous Integration defines when an automated build has to be generated.  CI is one of the software development practices where member of the team frequently integrates their code, which then undergoes build generation process verifying the code written by individuals. Generally, each member will integrate his/her code once in a day. Each integration is verified and tested as part of build generation process.

Continuous Build and Integration

 

  1. Developer commits his changes

  2. CI server polls Version Control repository every few minutes for changes.

  3. CI server picks up changes and kicks off the build script.

  4. Build scripts run and CI server generates a feedback based on the output of build script.

  5. Feedback is checked to ensure that the build has run successfully; if not, the developer addresses the issue.

  6. CI server keeps polling the Version Control Repository for more changes.

10) What are the benefits of Continuous Integration?

Software is deployable at any time. Having an immediate feedback mechanism helps the developers to quickly act if there are any issues.

Software quality increases as defects are prevented from being integrated.

Due to automated inspection and testing, software health can be tracked easily.

Results of the builds are published, which highlight the test cases that have failed.

Accountability of code is always recorded.

11) What are Design Patterns?

In simple terms, Design Patterns are the solution to problems faced by developers- they represent the best practices that are used by developers. Design Patterns help an inexperienced developer to learn easily and quickly. Design Patterns have standard terminologies addressing specific scenario.

There are mainly 3 types of Design Patterns:

  1. Creational: addresses design problems.

  2. Structural: simplifies relationships between objects.

  3. Behavioral: simplifies how objects interact with each other.

12) What is Component Based Development?

In CBD approach; unlike traditional way of development, developers look for existing well defined, tested and verified components to compose and assemble them to a product, instead of developing it from scratch.

13) Name a few cloud platform which are used for DevOps Implementation

Popular Cloud computing platform used for DevOps implementation are:

  1. Google Cloud
  2. Amazon Web Services
  3. Microsoft Azure

14) Give some benefits of using Version Control system

  • The version Control system allows team members to work freely on any file at any time.
  • All the past versions and variants are closely packed up inside the VCS.
  • A distributed VCS like helps you to store the complete history of the project so in case of a breakdown in the central server you can use your team member’s local Git repository.
  • Allows you to see what exact changes are made in the file’s content

15) Explain Git Bisect

Git bisect helps you to find the commit which introduced a bug using binary search.

16) What is the build?

A build is a method in which the source code is put together to check whether it works as a single unit.  In the build creation process, the source code will undergo compilation, inspection, testing, and deployment.

17) What is Puppet?

Puppet is a useful project management tool. It helps you to automate administration tasks.

18) Explain two-factor authentication

Two-factor authentication is a security method in which the user provides two ways of identification from separate categories.

19) Explain the term ‘Canary Release’.

A canary release is a pattern which reduces the risk of introducing a new version software into the production environment. It is done by making it available in a controlled manner to a subset of the user. Before making it available to the complete user set.

20) What types of testing is important to ensure that new service is ready for production?

You need to conduct continuous testing to ensure that the new service is ready for production.
