AZ-204 Developing for Microsoft Azure Exam Prep - Creating a Cosmos Database (DB) Collection

The video tutorial guides users through setting up a Cosmos DB account on Azure, enabling Geo-replication, and using the quick start feature to create dummy data and collections. It explains the process of creating a database and collection, defining a partition key, and setting throughput. The tutorial also covers the importance of unique keys and finalizes the collection setup, highlighting features similar to SQL Server databases.

What is the purpose of enabling Geo-replication in Cosmos DB?

• To allow data to be replicated across multiple regions

• To increase the speed of data processing

• To reduce the cost of data storage

• To enhance the security of the database

What can you create in Cosmos DB to experiment with data?

• A virtual machine

• A blockchain ledger

• A sample app with dummy data

• A real-time data stream

What are the two layers of data within a Cosmos DB account?

• Tables and Views

• Databases and Collections

• Schemas and Tables

• Nodes and Clusters

What is the consequence of setting a high throughput limit at the database level?

• It increases the speed of data processing

• It reduces the overall cost

• It significantly increases the cost

• It enhances data security

What is the minimum throughput setting at the collection level in Cosmos DB?

• 200 request units per second

• 100 request units per second

• 500 request units per second

• 400 request units per second

Why is it important to choose a good partition key in Cosmos DB?

• To increase the speed of data retrieval

• To enhance the security of the database

• To ensure data is evenly distributed across servers

• To reduce the cost of data storage

What feature in Cosmos DB ensures that a field like employee ID is unique?

• Throughput limit

• Geo-replication

• Partition key

• Unique keys
