HTTP u0026 REST fundamentals Quiz

Test your knowledge of HTTP and REST fundamentals with this quiz focused on status codes, pagination, idempotency, and best practices for designing HTTP requests and responses. Perfect for developers and professionals aiming to strengthen their understanding of core web communication concepts.

1. Identifying Success Responses

   When a REST API successfully processes a GET request to retrieve a resource, which HTTP status code should typically be returned?

   1. 404 Not Found
   2. 200 OK
   3. 301 Moved Permanently
   4. 500 Internal Error

2. Understanding Idempotency

   Which HTTP method is considered idempotent because multiple identical requests will have the same effect as a single request?

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

3. Implementing Pagination Parameters

   In a RESTful API, which pair of query parameters are most commonly used to implement pagination for a list endpoint?

   1. limit and skip
   2. page and per_page
   3. index and count
   4. size and jump

4. Indicating Creation of Resources

   If a POST request successfully creates a new resource, which HTTP status code should be returned along with a Location header indicating the new resource’s URI?

   1. 204 No Content
   2. 403 Forbidden
   3. 201 Created
   4. 202 Accepted

5. Clarifying Incorrect Resource Paths

   Which status code is most appropriate when a client requests a REST resource at a URI that does not exist?

   1. 500 Internal Error
   2. 400 Bad Request
   3. 404 Not Found
   4. 401 Unauthorized

6. Representing Error Details

   What is the recommended format for detailed error messages in RESTful APIs to ensure clarity and machine readability?

   1. Binary data
   2. JSON object with error fields
   3. Plain text string
   4. XML only

7. Managing Partial Updates

   Which HTTP method is typically used for partial updates to an existing REST resource, such as updating only an email field on a user profile?

   1. DELETE
   2. TRACE
   3. PATCH
   4. GET

8. Distinguishing Idempotency in Methods

   Which HTTP method is not guaranteed to be idempotent and can result in multiple new resources being created if the same request is sent multiple times?

   1. HEAD
   2. DELETE
   3. GET
   4. POST

9. Communicating No Content Responses

   After successfully processing a DELETE request with no response data, which HTTP status code should typically be returned?

   1. 202 Accepted
   2. 409 Conflict
   3. 302 Found
   4. 204 No Content

10. Designing Resource URIs in REST

    When designing RESTful URIs for accessing individual resources, which format is best practice for retrieving a user with the unique ID of 25?

    1. /usersu0026id:25
    2. /users/25
    3. /users?id=25
    4. /user-25
