The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Does Cloudflare offer certifications?

Cloudflare offers training paths and partner certifications for its platform, and its documentation and Learning Center cover the same core skills. Employers usually test practical knowledge of DNS and proxying, caching, SSL/TLS modes, WAF and bot rules, Zero Trust and Workers, which this test covers.

What is the difference between proxied and DNS-only records in Cloudflare?

A proxied record (orange cloud) sends traffic through Cloudflare's network, hiding the origin IP and applying caching, security and performance features. A DNS-only record (grey cloud) simply resolves to the origin, so Cloudflare's protections and caching do not apply.

Can I take the Cloudflare Certification from any country?

Yes. The test is online, in English and free everywhere — people take it from India, the US, the UK, Europe, Africa, Latin America and Asia-Pacific. Your certificate is dated with your own local date and can be verified from anywhere at scienceofapps.com/certification/verify/.
