- E
Verify that the HTTPS load balancer has a valid SSL/TLS certificate in place.
Show answer and explanation
Correct answers: A, B, E
Explanation
To configure Cloud CDN, it must be enabled on the backend service of the HTTPS load balancer. The backend service must already have a defined backend (instance group or backend bucket), and a valid SSL/TLS certificate is required for HTTPS traffic. While caching policies can be customized, they are defined via the backend service or URL maps, not directly on Cloud CDN. A custom domain is optional and not required to enable Cloud CDN.
- A. Correct.
Correct. Cloud CDN must be enabled on the backend service associated with the HTTPS load balancer to cache and serve content.
- B. Correct.
Correct. The backend service must have at least one instance group or backend bucket to serve content, as Cloud CDN works in conjunction with the backend service.
- C. Incorrect.
Incorrect. Caching policies are configured via the backend service or URL maps, not directly on the Cloud CDN service.
- D. Incorrect.
Incorrect. While a custom domain may be desirable for your application, it is not a mandatory step to enable Cloud CDN.
- E. Correct.
Correct. A valid SSL/TLS certificate is required for HTTPS load balancers, which is necessary for Cloud CDN to function correctly.
