One of the main benefits of CI/CD is _______ feedback loop for developers.
- Faster
- Longer
- Manual
- Predictable
One of the primary benefits of CI/CD is a faster feedback loop for developers. With automated testing and continuous integration, developers receive prompt feedback on their code changes, enabling quick identification and resolution of issues.
You're designing a system that needs to handle massive amounts of write operations with low latency. Which NoSQL database would be the most suitable choice and why?
- Amazon DynamoDB
- Apache Cassandra
- Couchbase
- HBase
Apache Cassandra is a highly scalable NoSQL database designed for handling massive write operations with low latency. It is a distributed and decentralized system that excels in write-intensive workloads.
You notice that the website you designed is not rendering properly on a particular mobile device. How would you troubleshoot and resolve this issue?
- Check CSS media queries for compatibility
- Ensure proper meta tags for responsiveness
- Examine viewport settings in the HTML
- Use browser developer tools for inspection
Utilizing browser developer tools allows inspection and debugging, helping identify and address rendering issues on specific devices.
In OAuth 2.0, the _______ grant type is commonly used for server-to-server communication.
- Authorization Code
- Client Credentials
- Implicit
- Resource Owner Password Credentials
In OAuth 2.0, the Client Credentials grant type is commonly used for server-to-server communication. It allows a client to request an access token using its client credentials.
In a complex application, you have different algorithms for processing data, and you want to be able to switch between them dynamically. Which design pattern would you use to accomplish this?
- Command
- State
- Strategy
- Template Method
The Strategy pattern is suitable for situations where you have multiple algorithms and want to be able to switch between them dynamically. It defines a family of algorithms, encapsulates each one, and makes them interchangeable. This allows the client to choose the appropriate algorithm at runtime.
You're working on a project with multiple team members. Two developers have made conflicting changes to the same function in different branches. How would you approach resolving this merge conflict?
- Automatically accept one developer's changes and discard the other, prioritizing speed over collaboration.
- Escalate the conflict to higher management for resolution.
- Merge both changes as-is, and let the codebase adapt to the differences.
- Review the changes, communicate with the developers, and collaboratively decide on the best resolution.
Resolving a merge conflict involves collaboration and communication. Reviewing changes together allows developers to discuss the best solution, fostering teamwork and understanding.
In TDD, what is the purpose of a "failing test"?
- To confirm code correctness
- To identify bugs
- To outline future features
- To provide documentation
The purpose of a "failing test" in Test-Driven Development (TDD) is to identify bugs. A failing test indicates that the code does not meet the expected behavior, prompting the developer to fix the issues before proceeding.
Your team needs to implement a new feature in an existing project. Explain how you would leverage collaboration tools to manage the development process and ensure timely delivery.
- Create a project board with tasks, assign responsibilities, set milestones, and use a chat platform for real-time communication
- Share a list of tasks via email, conduct weekly status meetings, and update a physical task board in the office
- Use individual to-do lists, communicate through personal chat applications, and rely on individual project timelines
- Utilize a whiteboard for task management, assign tasks verbally during team meetings, and rely on individual project timelines
Leveraging collaboration tools involves creating a project board, assigning tasks, setting milestones, and using chat platforms for real-time communication. This approach ensures a structured development process and facilitates timely delivery through effective task management.
The "Console" tab in Browser Developer Tools is used for logging _______ messages.
- Debug
- Error
- Info
- Warning
The "Console" tab in Browser Developer Tools is used for logging debug messages. Developers can use the console to log information, debug code, and identify issues during development.
Which of the following is NOT a common level of severity used in logging systems?
- Debug
- Fatal
- Info
- Warning
Debug is not a common level of severity used in logging systems. The common levels include Info, Warning, Error, and Fatal. Debug is usually more detailed and is used during development for debugging purposes.
