This assessment mirrors the scenarios you’d face in real-world NoSQL database development and administration. From selecting the right NoSQL type for a given use case to implementing performance optimizations, each question pushes you to think strategically about data handling in distributed environments.

You’ll be evaluated across four essential skill areas:

• Core Concepts
Understand the different categories of NoSQL databases—document, key-value, column-family, and graph—along with their advantages and trade-offs.

• Database Operations & Optimization
Perform CRUD operations, design efficient queries, manage indexes, and apply techniques to improve speed and scalability.

• Data Modeling & Architecture in NoSQL
Design schemas that suit denormalized and flexible data structures while ensuring maintainability and consistency.

• Advanced Concepts
Apply sharding, replication, consistency models, and eventual consistency strategies for distributed systems.

This is where design decisions directly impact application performance, scalability, and maintainability.
