Which HTTP status code indicates the requested resource could not be located?

• A. 202
• B. 404
• C. 606
• D. 999

Answer: (B)

When a web server can’t find the resource you’re asking for, it returns a 404 Not Found status. This means the URL you requested doesn’t map to anything on the server—maybe the page was moved, deleted, or the URL was typed incorrectly. The 404 code is a standard, widely recognized way for the server to tell your browser or client that the resource doesn’t exist at that location.

The other options don’t fit. A 202 status means the request was accepted for processing, but the processing hasn’t finished yet, which is unrelated to whether the resource exists. The other two codes aren’t valid standard HTTP responses for a missing resource—one isn’t defined in the HTTP specification and the other is nonstandard and not used in normal HTTP communication.
