REST API and Web Services Quiz

To pass the quiz, you must correctly answer at least 9 of the 10 questions below. # --quizzes-- ## --quiz-- ### --question-- #### --text-- What is the relationship between an API and a web service? #### --distractors-- Every API is a web service, but not every web service is an API. --- APIs and web services are identical concepts. --- Web services only work with REST, while APIs support multiple protocols. #### --answer-- Every web service is an API, but not every API is a web service. ### --question-- #### --text-- Which HTTP header does a client use to tell the server which response format it wants? #### --distractors-- `Content-Type` --- `Authorization` --- `X-Requested-With` #### --answer-- `Accept` ### --question-- #### --text-- Which of the following is true about SOAP compared to REST? #### --distractors-- SOAP uses JSON and is more flexible than REST, making it ideal for modern applications. --- SOAP is the most widely used web service type today, having replaced REST in most systems. --- SOAP supports multiple response formats, including plain text, JSON, and binary data. #### --answer-- SOAP uses only XML and is common in enterprise systems that need stricter standards and security. ### --question-- #### --text-- What does statelessness mean in a REST architecture? #### --distractors-- The server stores the client's session data between requests. --- The client keeps no state of its own across requests. --- REST restricts all requests to read-only operations. #### --answer-- The server stores no memory of previous requests. ### --question-- #### --text-- Which REST HTTP method is used to remove a resource? #### --distractors-- `GET` --- `POST` --- `PUT` #### --answer-- `DELETE` ### --question-- #### --text-- In a REST architecture, what is a resource? #### --distractors-- A function that formats HTTP responses before they are sent to the client. --- A temporary variable stored in the client's browser. --- A configuration file that lists the available HTTP methods. #### --answer-- A piece of data that can be accessed or modified, identified by a URL. ### --question-- #### --text-- Which HTTP status code indicates that a new resource was successfully created? #### --distractors-- `200` --- `400` --- `404` #### --answer-- `201` ### --question-- #### --text-- What does a `500` status code indicate? #### --distractors-- The client sent invalid data to the server. --- The requested resource does not exist. --- The request was successful. #### --answer-- An error occurred on the server while processing the request. ### --question-- #### --text-- What is a key advantage of microservices over a monolith? #### --distractors-- Simpler debugging and fewer network calls between services. --- A single shared codebase that all teams contribute to. --- Easier infrastructure management across all services. #### --answer-- Faster development, better fault isolation, and the ability to use different languages per service. ### --question-- #### --text-- Which of the following is a challenge of adopting a microservices architecture? #### --distractors-- A single, shared codebase that makes changes easy to coordinate. --- Fewer network calls are needed between components. --- Debugging becomes simpler since all code runs in one process. #### --answer-- Debugging becomes more complex, and there is more network overhead between services.
