Q23. Your company’s Google Cloud-deployed, streaming application supports multiple languages. The application development team has asked you how they should support splitting audio and video traffic to different backend Google Cloud storage buckets. They want to use URL maps and minimize operational overhead. They are currently using the following directory structure:
/fr/video
/en/video
/es/video
/../video
/fr/audio
/en/audio
/es/audio
/../audio
Which solution should you recommend?

Rearrange the directory structure, create a URL map and leverage a path rule such as /video/* and /audio/
*.

Rearrange the directory structure, create DNS hostname entries for video and audio and leverage a path rule such as /video/* and /audio/*.

Leave the directory structure as-is, create a URL map and leverage a path rule such as /[a-z]{2}/video and
/[a-z]{2}/audio.
