Microsoft Azure Developer Associate AZ-204 Practice Question

You are developing an Azure Functions app that reads individual orders from an Azure Cosmos DB Core (SQL) API database. During each function execution you know both the orderId (stored in the id property) and the customerId (used as the partition key). You must retrieve the matching item using the least possible request units and the lowest latency. Which method of the Azure Cosmos DB .NET SDK v3 should you call?

  • Container.UpsertItemAsync(order)

  • Container.GetItemQueryIterator<Order>(new QueryDefinition("SELECT * FROM c WHERE c.id = @id").WithParameter("@id", orderId))

  • Container.GetItemLinqQueryable<Order>().Where(o => o.Id == orderId).AsEnumerable().First()

  • Container.ReadItemAsync<Order>(orderId, new PartitionKey(customerId))
