Question 1

A small application needs to store 50 GB of simple user profile data (key-value pairs).

The application is hosted in a single Azure region. The data structure is flat, and queries will only ever look up a user by their unique UserID. The primary architectural driver is to minimize monthly costs.

Which data storage solution should you recommend?

Accepted Answer

Compare Azure Table Storage vs Cosmos DB Table API. Choose Table Storage when cost is the primary driver and global distribution is not needed.

Question 2

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

Accepted Answer

Defaulting to Cosmos DB for all NoSQL workloads. Cosmos DB is powerful but expensive for simple, single-region, cost-sensitive apps.
