You are designing an Azure Cosmos DB for NoSQL solution to store data from IoT devices. Writes from the devices will occur every second. Data will be retained indefinitely.The following is a sample of the data.You need to select a partition key that meets the following requirements for writes:• Minimizes the partition skew• Avoids capacity limits• Avoids hot partitionsWhat should you do?
HOTSPOT-You have an Azure Cosmos DB for NoSQL container named Contacts that is configured as shown in the following exhibit.Contacts contains the items shown in the following table.To Contacts, you plan to Insert the items shown in the following table.For each of the following statements, select Yes if the statement is true. Otherwise, select No.NOTE: Each correct selection is worth one point.
HOTSPOT-You plan to create an Azure Cosmos DB container named account that will contain items in the following format.You need to define a query that will return the ids of all accounts that have ever recorded a negative value for balance.How should you complete the query? To answer select the appropriate options in the answer area.NOTE: Each correct selection is worth one point.
HOTSPOT-You have the Azure Cosmos DB for NoSQL containers shown in the following table.You have the items shown in the following table.When will each item expire? To answer, select the appropriate options in the answer area.NOTE: Each correct selection is worth one point.
Your company develops an application named App1 that uses the Azure Cosmos DB SDK and the Eventual consistency level.App1 queries an Azure Cosmos DB for NoSQL account named account1.You need to identify which consistency level to assign to App1 to meet the following requirements:• Maximize the throughput of the queries generated by App1 without increasing the number of request units currently used by the queries.• Provide the highest consistency guarantees.Which consistency level should you identify?
You plan to create an Azure Cosmos DB account that will use the NoSQL API.You need to create a grouping strategy for items that will be stored in the account. The solution must ensure that write and read operations on the items can be performed within the same transaction.What should you use to group the items?
