Explanation

To configure Cloud CDN with an external backend like a third-party object storage system, you must create an internet NEG pointing to the external endpoint, enable Cloud CDN on the backend service associated with the NEG, and ensure proper cache expiration policies are set. These steps allow Cloud CDN to cache and serve the content efficiently. Intermediary Cloud Storage buckets or incorrect DNS configurations are not required for this setup.

  • A. Correct.

    Correct. An internet NEG is required to route traffic to an external backend such as a third-party object storage system.

  • B. Correct.

    Correct. Cloud CDN must be explicitly enabled on the backend service associated with the internet NEG to cache content.

  • C. Incorrect.

    Incorrect. You do not need to use a Cloud Storage bucket as an intermediary when using Cloud CDN with an internet NEG.

  • D. Incorrect.

    Incorrect. DNS records should point to the Cloud CDN IP address, not the external backend's IP address, to ensure the CDN serves cached content properly.

  • E. Correct.

    Correct. Proper cache expiration policies in the backend configuration or HTTP headers are necessary to control the caching behavior of Cloud CDN.
