What is a key principle of RESTful API design?

Resources are identified by URLs and manipulated using standard HTTP methods.

The client can request exactly the fields it needs in a single query.

The API uses a single endpoint for all operations, with the operation specified in the request body.

The server maintains the client's session state between requests.

What is the primary purpose of WebAssembly?

To enable high-performance execution of code in web browsers.

To provide a styling language for web pages.

To replace HTML and CSS for building web pages.

To define the structure of web documents.

A startup is building a collaborative document editor that must provide real-time updates to multiple users without full page reloads. The team is deciding between a traditional multi-page application (MPA) and a single-page application (SPA). Which factor is most important when choosing the SPA approach?

The SPA will require a more complex client-side state management system.

The SPA will reduce the initial page load time compared to an MPA.

The SPA will have better search engine optimization (SEO) out of the box.

The SPA can update the UI dynamically without reloading the entire page.

A team is developing a browser-based video editing tool that needs to perform complex image processing at near-native speed. JavaScript performance is insufficient for the required frame-by-frame manipulation. Which technology should they use to run the performance-critical code in the browser?

A server-side application to process the video and stream it back

A JavaScript framework like React or Vue.js

A non-profit organization needs to launch a website quickly. The staff are not technical and need to publish news articles, event pages, and photo galleries without writing code. They also need a simple way for volunteers to submit content for review. Which solution best meets these requirements?

A custom-built static site generator with a Git-based workflow

A simple HTML website with files edited directly on the server

A single-page application (SPA) developed with React and a REST API

A content management system (CMS) like WordPress or Drupal
