Which deployment strategy gradually releases a new feature or update to a small subset of users before the full deployment?
- Blue-Green Deployment
- Canary Deployment
- Feature Toggles Deployment
- Rolling Deployment
Canary Deployment is a strategy that gradually introduces new features to a small group of users, ensuring early feedback and reducing the risk of issues in a broader release.
How does atomicity in commits benefit Source Code Management?
- It accelerates code compilation.
- It ensures security of source code.
- It increases source code storage space.
- It simplifies branching and merging.
Atomic commits in Source Code Management ensure that changes to the codebase are made in a single, self-contained unit. This simplifies branching, merging, and tracking changes, leading to more effective code management.
You are tasked with ensuring that a new API endpoint is returning the correct data and handling errors gracefully. Which type of testing would be most appropriate to perform first?
- Functional Testing
- Integration Testing
- Regression Testing
- Unit Testing
The most appropriate testing to perform first in this scenario is Unit Testing. Unit testing focuses on testing individual components, like functions or methods, to ensure they work correctly. It's ideal for early-stage validation of code behavior and handling errors gracefully.
The _____ architectural style in Software Architecture Design involves a client sending requests to a server, which then sends back a response.
- Client-Server
- Layered
- Peer-to-Peer
- Publish-Subscribe
The Client-Server architectural style involves a client making requests to a server, which processes the requests and sends back responses. It's a common architecture for distributed systems.
What is the benefit of adhering to a consistent coding style across a project?
- It eliminates the need for testing.
- It ensures bug-free code.
- It improves team collaboration.
- It makes the code run faster.
Adhering to a consistent coding style across a project enhances team collaboration and code maintainability. It makes the code easier to read, understand, and maintain, leading to improved communication and teamwork among developers.
Which Jenkins feature allows you to run tests automatically every time a code change is pushed to the repository?
- Build Triggers
- Git Hooks
- Poll SCM
- Webhooks
The Build Triggers feature in Jenkins enables automatic test execution whenever a code change is pushed to the repository, ensuring continuous integration and rapid feedback on code changes.
How can Jenkins administrators monitor and audit user activities within the system?
