Jenkins

Ques:- What is the difference between Jenkins and other CI/CD tools like GitLab CI or CircleCI?

Asked In :- C E I India, Diya Systems (Mangalore), ANR Software, Payoda, Test Yantra, EvolveWare, Softsuave, Reliance Jio, Slk Software Pvt Ltd, Coforge,

Right Answer:

Jenkins is an open-source automation server that allows for extensive customization and integration with various plugins, making it highly flexible. In contrast, GitLab CI is tightly integrated with GitLab repositories, providing a seamless experience for users within that ecosystem, while CircleCI focuses on cloud-based CI/CD with a user-friendly interface and predefined configurations. Jenkins typically requires more setup and maintenance, while GitLab CI and CircleCI offer more out-of-the-box solutions with less configuration needed.

2. **Configure Master Node**: Go to "Manage Jenkins" > "Manage Nodes and Clouds" > "New Node" to create a new node.
3. **Choose Node Type**: Select "Permanent Agent" and provide a name for the slave node.
4. **Configure Node Settings**: Set the remote root directory, labels, and usage options.
5. **Launch Method**: Choose how to connect the slave (e.g., via SSH, JNLP, or Windows service).
6. **Install Required Software**: Ensure the slave node has Java and any other necessary tools installed.

Jenkins

Ques:- What is a Jenkins pipeline? Explain declarative vs scripted pipelines.

Asked In :- EdgeVerve Systems, C E I India, Bristlecone India, Chella Software, PrimeSoft Solutions, ANR Software, Zessta Software Services, Intelizign, BluePi, Eidiko Systems Integrators,

Right Answer:

A Jenkins pipeline is a suite of plugins that supports implementing and integrating continuous delivery pipelines into Jenkins. It allows you to define the entire build process as code.

There are two types of pipelines in Jenkins:

1. **Declarative Pipeline**: This is a more structured and simpler way to define a pipeline using a predefined syntax. It uses a specific set of keywords and is easier to read and write, making it suitable for most users.

2. **Scripted Pipeline**: This is a more flexible and powerful way to define a pipeline using Groovy scripting. It allows for complex logic and customizations but can be more challenging to write and maintain.

Agile

Ques:- How do you handle scope creep or changes during a sprint

Asked In :- Vinove Software & Services Pvt Ltd, Xoriant Solutions Pvt Ltd, AnAr Solutions, Toxsl Technologies, Itobuz Technologies, iROID Technologies, LiteBreeze Infotech, Oodles Technologies, Sun Dew Solutions, Radicle Software,

Right Answer:
During a sprint, I generally avoid scope creep. If a change request is small and doesn't impact the sprint goal, the team can discuss and decide if it can be included. If the change is significant, it goes into the product backlog to be prioritized for a future sprint.

Agile

Ques:- What is the difference between Kanban and Scrum, and when would you use each

Asked In :- Unyscape Infocom Pvt. Ltd., Winsoft Technologies India Pvt. Ltd, DREAMORBIT SOFTECH PVT, Object Frontier Software, Hidden Brains InfoTech, Queppelin Technology Solutions, Walkover Web Solutions, Ziffity Solutions, Chegg India, Codiant Software Technologies,

Right Answer:
Kanban focuses on visualizing workflow, limiting work in progress (WIP), and continuous flow. Scrum uses time-boxed iterations (sprints) with specific roles (Scrum Master, Product Owner, Development Team) and events (sprint planning, daily scrum, sprint review, sprint retrospective).

Use Kanban when you need continuous delivery, have evolving priorities, and want to improve workflow incrementally. Use Scrum when you need structured development with fixed-length iterations, have clear goals for each iteration, and benefit from team collaboration with defined roles.

Agile

Ques:- What is a product backlog, and how do you manage it

Asked In :- KRIOS Info Solutions, Trigent Software, Toxsl Technologies, Addweb solutions, Solace Infotech, Spadeworx Software Services, Dhruvsoft Services, FIS Global Business Solutions India, QuickXpert Infotech, Enovate IT Outsourcing,

Right Answer:
A product backlog is a prioritized list of features, bug fixes, tasks, and requirements needed to build a product. It's managed through regular refinement, prioritization, estimation, and updates based on feedback and changing business needs, often facilitated by the Product Owner.

Agile

Ques:- Can you describe a time when an Agile project didn’t go as planned and how you handled it

Asked In :- Xoriant Solutions Pvt Ltd, KRIOS Info Solutions, Netaxis IT Solutions (p), Trigent Software, Fortunesoft IT Innovations, Born Commerce, TNQ Technologies, LiteBreeze Infotech, Oodles Technologies, Sun Technology Integrators,

Right Answer:
"In one project, we underestimated the complexity of integrating a new third-party API. This caused us to miss our sprint goal. To address this, we immediately re-estimated the remaining work, broke down the integration into smaller, more manageable tasks, and increased communication with the API vendor. We also temporarily shifted team focus to prioritize the integration, delaying a lower-priority feature for the next sprint. Finally, in the sprint retrospective, we implemented a better vetting process for third-party integrations to avoid similar issues in the future."

Asked In :- Tredence Analytics Solutions, C E I India, Berger Paints, Amiti Software Technologies, Talencia LLC, Vayavya Labs, BridgeLabz Solutions, Relinns Technologies, Metrics4 Analytics, Thryve Digital,

Right Answer:
Tableau actions are interactive features that allow users to engage with visualizations by triggering responses based on their interactions. There are three main types of actions: Filter actions, Highlight actions, and URL actions. These actions enhance user interactivity by enabling users to explore data dynamically, focus on specific data points, and navigate to external resources, making the data experience more engaging and insightful.

Asked In :- C E I India, PrimeSoft Solutions, PreludeSys India, Code Board Technology, Amiti Software Technologies, ESAF Small Finance Bank, C-Edge Technologies, Nalsoft, Profound Edutech, Gallagher Offshore,

Right Answer:
In Power BI, Import mode loads data into the Power BI model, allowing for faster performance and advanced data modeling features, while DirectQuery mode connects directly to the data source, querying it in real-time without storing the data in Power BI, which can lead to slower performance but ensures the data is always up-to-date.
