What are some best practices for testing responsiveness across different devices and screen sizes?

  • Conducting tests only during development, not considering user feedback, ignoring real-world scenarios
  • Ignoring testing altogether, assuming responsiveness will work automatically, relying only on manual testing
  • Testing only on one device, relying solely on emulators, neglecting testing on various screen sizes
  • Using browser developer tools, utilizing online testing tools, conducting real device testing, and simulating different viewports
Best practices for testing responsiveness involve using browser developer tools, utilizing online testing tools, conducting real device testing, and simulating different viewports to ensure compatibility across a variety of devices and screen sizes.

NoSQL databases offer _______ scalability compared to traditional relational databases.

  • Dynamic
  • Horizontal
  • Static
  • Vertical
NoSQL databases offer Horizontal scalability compared to traditional relational databases. This means that the system can handle increased load by adding more nodes to the database.

A _______ attack aims to overload a system's resources, making it unavailable to users.

  • Cross-Site Scripting
  • Denial-of-Service
  • Man-in-the-Middle
  • SQL Injection
A Denial-of-Service (DoS) attack aims to overload a system's resources, making it unavailable to users. This is often achieved by flooding the targeted system with excessive requests, causing it to become overwhelmed and unresponsive.

What is the difference between == and === operators in JavaScript?

  • Checks for equality in value and type
  • Checks for inequality in value and type
  • Checks only for equality in type
  • Checks only for equality in value
The == operator in JavaScript checks for equality in value, while the === operator checks for equality in both value and type. It is a strict equality check.

What is a design pattern in software engineering?

  • A blueprint for creating software applications
  • A general reusable solution to a commonly occurring problem within a given context in software design
  • A programming language-specific code convention
  • A step-by-step guide for designing user interfaces
A design pattern in software engineering is a general reusable solution to a commonly occurring problem within a given context in software design. It represents best practices and provides a template for solving particular issues.

The "git rebase -i" command allows for _______ commits interactively.

  • Randomizing
  • Recovering
  • Reversing
  • Rewriting
The "git rebase -i" command allows for Rewriting commits interactively. It opens an interactive interface where you can squash, pick, edit, and reorder commits, providing flexibility in managing commit history.

React makes use of a virtual _______ to efficiently update the DOM.

  • Browser
  • Component
  • DOM
  • Tree
React makes use of a virtual DOM to efficiently update the actual DOM. The virtual DOM is a lightweight copy of the real DOM, and changes are first made to the virtual DOM for faster updates.

In the context of database optimization, what does query optimization involve?

  • Enhancing Query Performance
  • Improving Database Security
  • Minimizing Data Redundancy
  • Optimizing Data Types
Query optimization in the context of database optimization involves improving the performance of database queries. This includes optimizing query execution plans, indexing, and other factors to enhance overall query performance.

During a code review, you notice that a colleague frequently introduces merge conflicts due to large, sweeping changes. How would you address this issue to improve collaboration and code stability in the project?

  • Ignore the issue and let the colleague handle their approach to code changes.
  • Implement strict branch control, limiting the number of branches for each developer.
  • Provide constructive feedback, suggesting smaller, more frequent commits and communication about upcoming changes.
  • Raise the concern in a team meeting, highlighting the impact on code stability.
Offering constructive feedback encourages a positive environment. Suggesting smaller, more frequent commits fosters better collaboration and reduces the likelihood of disruptive conflicts.

GitHub Flow encourages _______ deployment of code changes to production.

  • batch
  • continuous
  • manual
  • scheduled
GitHub Flow encourages continuous deployment of code changes to production. This approach emphasizes regularly and automatically deploying smaller, incremental changes to ensure a more stable and agile development process.
