- [ ] Cutting-edge Technology developped for high-performance video streaming on web browsers (Real-time Event Streaming Technology) - [ ] Set of best practices and state-of-art technological recommendations for storage area networks (Resource Extraction and Storage Technology) - [ ] Set of guidelines for designing the export nethods of logical entities from an information system (REpresentational Entity State Transfer) - [x] Set of guidelines for designing stateless and loosely coupled client-server architectures around resources and operations on them (REprentational State Transfer) # Networking (suite) What is the difference between a GET and a POST request that will be sent when submitting a form ? - [ ] GET are used for accessing a resource and data is transmitted in the request body ; POST are used for creating/updating resource and data is transmitted in the URL - [ ] GET are used for creating/updating resource and data is transmitted in the URL ; POST are used for accessing a resource and data is transmitted in the request body - [x] GET are used for accessing a resource and data is transmitted in the URL ; POST are used for creating/updating resource and data is transmitted in the request body - [ ] From a practical viewpoint, there is no difference # Networking (suite) What is the difference between a PUT and a POST request ? - [x] POST is used for creating a new resource on the server while PUT is used to update a resource, or replace it entirely but at same URI - [ ] POST is used for creating a new resource while PUT only updates it with url parameters encoded data - [ ] POST is used to alter an existing resource post-creation while PUT is used to create (put) a new resource ; both request type are using body request data - [ ] POST and PUT do the same thing ; you can use one or the other interchangeably # Networking (suite) What is the difference between a PUT and a PATCH request ? - [x] PUT is meant to update the resource by an entire new representation, while PATCH is used to make partial updates of the resource ; both request make use of request body data - [ ] PUT is used to update the resource while PATCH is solely used for data retrieval operations - [ ] PUT is used to update the resource while PATCH is specifically designed to delete the resource - [ ] Both request types are handled the same way by the server # Networking (suite) Which of the following statements accurately describe the caching mechanism ? - [x] It's implemented by HTTP headers that indicates the cache livetime such as `Cache-Control` and `Expires` - [ ] The server notifies the client when it should refresh the web page to always have an up to date version - [x] It allows client-side storing of web pages and their associated resources (images, scripts, stylesheets) - [ ] It's a security feature that prevents the other web pages opened in the browser to access the private data of the cached website # Networking (suite) What is the purpose of the ETag (Entity Tag) in web development? - [ ] It is used for encrypting sensitive data transmitted between the client and server - [x] It is a unique identifier assigned to a specific version of a web resource, such as a web page or file - [ ] It is a JavaScript library for implementing real-time communication between the client and server - [ ] It is a security mechanism that prevents cross-site scripting (XSS) attacks # Data storage (suite) What is the primary purpose of web cookies ? - [ ] To store sensitive user data on the client-side - [x] To track and store user information for personnalization and session management - [ ] To feed you during long web surfing sessions - [ ] To enable cross-site scripting and facilitate communication between different domains # Errors codes How many HTML error codes classes are there ? - [x] 5 - [ ] 7 - [ ] 9 - [ ] 11 # Content styling What is used CSS (Cascading Style Sheets) for ? > More than 1 good answer in the list - [x] Appareance and layout - [x] Animations - [x] Separation of concerns between content and style - [ ] OpenGL acceleration # Security What is the main difference between Cross-Origin Resource Sharing (CORS) and Cross-Site Scripting (XSS)? - [x] CORS is a mechanism that allows restricted resources (e.g., fonts, JavaScript) on a web page to be requested from another domain, while XSS is a vulnerability that allows malicious scripts to be injected into trusted websites. - [ ] CORS and XSS are two different names for the same security vulnerability that allows an attacker to manipulate a website's content. - [ ] CORS and XSS are both security mechanisms designed to prevent unauthorized access to web resources from different origins. - [ ] CORS and XSS are unrelated terms used in web development, with no specific relationship or significance. # Security (suite) What is the primary purpose of browser sandboxing ? - [ ] To enable cross-origin resource sharing (CORS) between websites - [ ] It's a system that enables JS real-time transpilation of javascript to optimize its execution time - [x] It isolates each web page to prevent fraudulent access to system resources or informations belonging to other openened web pages - [ ] Container that prevent the other web pages to access to the informations of the website you're currently bronwsing on
