Correct answer & explanation
✓
Use Cloud CDN signed cookies with a key defined in the backend bucket
Cloud CDN supports signed URLs and signed cookies to control access to private content. IAM conditions are not supported directly with Cloud CDN. CNAME records are DNS configuration, not access control. Cloud Armor is for security policies but not for generating signed URLs.
