Show answer and explanation
Correct answers: A, B, D
Explanation
To effectively configure Cloud CDN, you need to ensure that cacheable content has appropriate Cache-Control headers and that Cloud CDN is enabled on the correct backend service or bucket. Additionally, for security purposes, signed URLs or signed cookies can be used to restrict access to cached content. Configuring SSL certificates and enabling Cloud Armor are important for security but are not specific to the core functionality of Cloud CDN.
- A. Correct.
Correct. Cloud CDN relies on proper Cache-Control headers to determine whether content is cacheable and how long it should be cached.
- B. Correct.
Correct. Cloud CDN must be explicitly enabled on the backend service or backend bucket to function.
- C. Incorrect.
Incorrect. While configuring SSL certificates is important for secure connections, it is not directly related to enabling or configuring Cloud CDN.
- D. Correct.
Correct. Signed URLs or signed cookies are needed to restrict access to cached content when security is a concern.
- E. Incorrect.
Incorrect. Cloud Armor provides protection against DDoS attacks but is not a requirement for configuring Cloud CDN.
