Visual checkpoint

Use this diagram to locate the state and failure boundaries tested by the questions. Answer all five questions before revealing feedback; the result is a study checkpoint rather than a certification.

Browser → DNS resolver (resolve name); Browser → Edge / CDN (HTTPS request); Edge / CDN → API origin (cache miss); API origin → Database (query); Private cache rules → Edge / CDN (constrain caching)

Review your reasoning

After checking answers, identify the incorrect assumption behind each missed question. Rewrite it as a rule with a concrete exception or failure case, then return to the lesson.

Trace the first request and a later request to the same HTTPS API. Which setup steps might be reused?

1. After DNS resolution, where does an ordinary HTTPS API request go?
2. The origin committed an order, but its response was lost. What does the client timeout prove?
3. Which property distinguishes an L7 HTTP proxy from a basic L4 balancer?
4. A public page loads quickly but its API query is slow. What should be measured first?
5. Which connection choice best fits server-only live status updates with resumable events?
