AZ-204 Exam - Question 121

Question

You develop Azure solutions.

You must connect to a No-SQL globally-distributed database by using the .NET API.

You need to create an object to configure and execute requests in the database.

Which code segment should you use?

Examice · Accepted Answer

To connect to a No-SQL globally-distributed database using the .NET API, you need to create an instance of the CosmosClient class. The CosmosClient class is designed specifically for handling interactions with Azure Cosmos DB, which is a globally-distributed No-SQL database. By creating a new CosmosClient object using the EndpointUri and PrimaryKey, you can configure and execute requests against the database. This approach is standard practice for connecting to Azure Cosmos DB in .NET.

Correct Answer: C

Azure Cosmos DB is a fully managed NoSQL database for modern app development. Single-digit millisecond response times, and automatic and instant scalability, guarantee speed at any scale.

// Create a new instance of the Cosmos Client
this.cosmosClient = new CosmosClient(EndpointUri, PrimaryKey)
//ADD THIS PART TO YOUR CODE
await this.CreateDatabaseAsync();

correct.

SlavMar · Answer

But why we assume it is Cosmos? 
App needs to access some No-SQL database that may already exist - maybe it is Cosmos, maybe not

https://docs.microsoft.com/en-us/azure/cosmos-db/sql-api-get-started
public static async Task Main(string[] args)
{
}

// ADD THIS PART TO YOUR CODE
/*
    Entry point to call methods that operate on Azure Cosmos DB resources in this sample
*/
public async Task GetStartedDemoAsync()
{
    // Create a new instance of the Cosmos Client
    this.cosmosClient = new CosmosClient(EndpointUri, PrimaryKey);
 answer is correct

Correct answer.
CosmosClient is the only one with the appropriate constructor.

Order:
Cosmos Client > Database > Container > Item

DParekh · Answer

There are two ways by which we can created cosmosclient instance.
1. CosmosClient cosmosClient = new CosmosClient(connectionString);
2. CosmosClient cosmosClient = new CosmosClient(EndpointUri, PrimaryKey)

So answer C is correct.
