Which HTTP status code class indicates a successful request?

• A. 2xx Successful
• B. 1xx Informational
• C. 3xx Redirection
• D. 4xx Client Error

Answer: (A)

HTTP status code classes describe the result of an HTTP request, and the 2xx family signals success. When a server handles a request without errors, it replies with a 2xx code, meaning the request was processed as intended and a proper response is provided. For example, 200 OK means the request succeeded and the response body contains the resource; 201 Created indicates a new resource was created as a result; 204 No Content shows success with no content in the response body.

In contrast, 1xx informational codes mean the request was received and the process is continuing, 3xx redirection codes tell the client to take additional action (like following a redirect), and 4xx client error codes indicate a problem with the request that the client must fix. Therefore, the class that indicates a successful request is the 2xx range.
