HTTP u0026 REST Essentials Quiz Quiz

Challenge your understanding of advanced HTTP and REST principles, including status codes, idempotency, and pagination. Each question is designed to test your expertise with nuanced real-world scenarios.

1. Status Code for Resource Creation

   When a REST API successfully creates a new resource in response to a POST request, which HTTP status code should it return to indicate the resource was created, as in creating a new user profile?

   1. 204 No Content
   2. 202 Accepted
   3. 200 OK
   4. 201 Created
   5. 203 Non-Authoritative Information

2. Understanding Idempotency

   Which HTTP method is considered idempotent, such that repeating the same request multiple times will always have the same effect as making it once, for example, updating the same settings repeatedly?

   1. POST
   2. PUT
   3. CONNECT
   4. PATCH
   5. SEND

3. Correct Usage of 404 Status

   Assuming a client requests /items/1234 but the item does not exist, which HTTP status code most accurately conveys that the resource was not found?

   1. 400 Bad Request
   2. 404 Not Found
   3. 403 Forbidden
   4. 409 Conflict
   5. 405 Method Not Allowed

4. Common Pagination Methods

   In REST APIs, which of the following is the recommended way to implement pagination when dealing with large datasets, such as listing thousands of articles?

   1. Paginating with a 426 status code
   2. Sending all results in a single response
   3. Adding page data to the URL hash (#)
   4. Using query parameters like 'limit' and 'offset'
   5. Relying on server-side sessions only

5. Semantic Distinction of 409 Status

   In a RESTful service, which scenario most appropriately returns a 409 Conflict status code, such as when a client POSTs to create a resource that would duplicate an existing unique item?

   1. The client's request method is not supported on the resource
   2. The client is unauthorized to access the resource
   3. The request data format is invalid
   4. The client's request conflicts with the current state of the resource
   5. The resource is temporarily unavailable due to maintenance
