NEW QUESTION 221

You have an Azure subscription that contains an Azure Cosmos DB for NoSQL account. The account hosts a container named Container1. At some point during the past 4S hours, Container1 was deleted. You need to restore the account to immediately before the deletion of Container1. The solution must minimize administrative effort. What should you do first?

A.    Review the event feed blade.
B.    Identify the last restorable timestamp.
C.    Create a new Azure Cosmos DB for NoSQL account.
D.    Restore Container1 to a different Azure Cosmos DB for NoSQL account.

Answer: B
Explanation:
Azure Cosmos DB provides a point-in-time restore (PITR) feature, which allows you to restore data to a previous state. To restore a deleted container like Container1, the first step is to identify the last restorable timestamp. This timestamp would be the point in time immediately before the deletion of the container. Once you have identified the correct timestamp, you can proceed with the restore process. Cosmos DB allows you to restore the container to either the same or a different account, but identifying the timestamp is the crucial first step.

NEW QUESTION 222

NEW QUESTION 223
You have an Azure Cosmos DB for NoSQL database named db1 that writes to multiple Azure regions. You need to test the performance of db1 in the secondary region. Which command should you run first?

A.    az cosmosdb location show
B.    az cosmosdb failover-priority-change
C.    az cosmosdb network-rule remove
D.    az cosmosdb sql database merge

Answer: B

NEW QUESTION 224
You have an Azure subscription that contains an Azure Cosmos DB for NoSQL account named account1. You plan to configure the Apache Kafka service as a data source for account1. What should you use to store the Kafka configuration?

A.    Apache Gremlin
B.    Apache ZooKeeper
C.    Apache Tomcat
D.    Azure Key Vault

Answer: D
Explanation:
If you’re using Azure Cosmos DB as your database, you connect to databases, container, and items by using an SDK, the API endpoint, and either the primary or secondary key. It’s not a good practice to store the endpoint URI and sensitive read-write keys directly within application code or configuration file. Ideally, this data is read from environment variables within the host. In Azure App Service, app settings allow you to inject runtime credentials for your Azure Cosmos DB account without the need for developers to store these credentials in an insecure clear text manner. Azure Key Vault iterates on this best practice further by allowing you to store these credentials securely while giving services like Azure App Service managed access to the credentials. Azure App Service will securely read your credentials from Azure Key Vault and inject those credentials into your running application.

NEW QUESTION 225
You have an Azure subscription that contains an Azure Cosmos DB for NoSQL database named DB1. You develop a software as a service (SaaS) app named App1 that uses DB1. App1 will be used by multiple vendors to manage their customers. You need to create a container in DB1 that will store customer and order details for each vendor. The solution must meet the following requirements:
– Each vendor must have a unique tenant ID.
– The performance of the container must be optimized for reads.
– Customer IDs can be duplicated across the container, but must be unique for each vendor.
– The container must be optimized for concurrent queries from multiple customers. Each query will return data for a single vendor.
How should you configure the container?

A.    Add a partition key to the tenant ID and a unique key policy to the customer ID.
B.    Add a hierarchical partition key on (tenant identifier, customer identifier).
C.    Add a partition key to the customer ID and a unique key policy to the tenant ID.
D.    Add a hierarchical partition key on (customer identifier, tenant identifier).
