Question 1

You are designing a globally distributed application using Azure Cosmos DB. The database is replicated across 4 regions.

The application is a social media feed. When a user posts an update, it is critical that the user immediately sees their own post. However, it is acceptable if users in other regions see the post with a slight delay. You want to maximize read throughput and minimize latency.

Which Cosmos DB consistency level should you recommend?

Accepted Answer

Identify the consistency level that specifically guarantees 'read-your-own-writes'.

Question 2

What mistakes do candidates make on this AZ-305 question?

Accepted Answer

Choosing Strong consistency. While Strong guarantees the user sees their post, it forces synchronous replication across all 4 regions, severely degrading latency and throughput.
