What is the most common cause of a 404 error?
- The data has been migrated to a new server.
- Your access token is outdated.
- You have an improperly scoped authentication method.
- The data is either deleted or archived.
Explanation: The statement ‘The data is either deleted or archived’ accurately identifies the most common cause of a 404 error, making it the correct choice. A 404 error, commonly known as ‘Not Found,’ occurs when a server cannot find the requested resource. This often happens when a client attempts to access a webpage or endpoint that does not exist or has been removed from the server. Therefore, if the data associated with a specific URL or endpoint has been deleted or archived, the server will return a 404 error to indicate that the requested resource is no longer available. The other options listed are potential causes of errors but are not specifically related to the 404 status code: ‘The data has been migrated to a new server’ could result in temporary downtime or redirects but would not necessarily cause a 404 error unless the migration process was incomplete or the resource was not properly redirected; ‘Your access token is outdated’ would typically result in a 401 Unauthorized or 403 Forbidden error rather than a 404 Not Found error; and ‘You have an improperly scoped authentication method’ might lead to authentication errors but would not directly trigger a 404 error unless it prevented access to a resource that does not exist. Therefore, understanding that a 404 error indicates that the requested resource is missing or inaccessible due to deletion or archival is crucial for diagnosing and resolving common web server issues.
