Quiz

A mobility platform wants to place data close to users in many regions. Which data can be replicated and which cannot?

A social platform serves user profiles from edge caches worldwide. A user updates their profile and still sees the old one. How should this be handled?

After a price change you issue a CDN purge and every point of presence returns 200. Twenty minutes later customers in one region still see the old price, and a hard refresh fixes it for some of them. Where do you look and in what order?

You enforce a rate limit of 100 requests per minute per user at the edge, across 40 locations. Abuse monitoring shows a user making 3,000. Explain.
