When a user requests a cacheable document from the AEM Dispatcher, what will the Dispatcher check to access whether the document exists in the web server file system? Choose two.

A. If the document is not cached, the Dispatcher requests the document form the AEM instance

B. If the document is not cached, the Dispatcher returns a 404 error response

C. If the document is cached, the AEM Dispatcher returns the file from the CDN Cache

D. If the document is cached, the AEM Dispather requests the cached file after validation
