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 partitions What should you do?
Answer: B
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?
Answer: B
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?
Answer: B
You provision an Azure Cosmos DB for NoSQL container. You set the throughput to Autoscale, and the maximum request units per second (RU/s) to 20,000. For how many RU/s will you be charged when the actual RU/s usage is zero?
Answer: C
You have an Azure Cosmos DB for NoSQL account that contains a database named DB1 and a container named Container1. You need to manage the account by using the Azure Cosmos DB SDK. What should you do?
Answer: A
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?
Answer: D
You plan to create an Azure Cosmos DB for NoSQL account that will have a single write region and three read regions. You need to set the consistency level for the account. The solution must meet the following requirements: • In the write region, writes must replicate synchronously across at least three replicas. • In the read regions, reads must see writes in order for transactional batches. • Throughput for reads and writes must be maximized. Which consistency level should you select?
Answer: A
You have an Azure subscription. The subscription contains an Azure Cosmos DB for NoSQL account named account1 that uses a default consistency level of Consistent Prefix. You execute a SELECT query and specify the Consistent Prefix consistency level. You need to execute a second SELECT query during the same session and specify a lower consistency level. Which consistency level can be used for the second SELECT query?
Answer: D
You have an Azure subscription that contains an Azure Cosmos DB for NoSQL database named DB1. In DB1, you plan to create a container that will use a hierarchical partition key. You need to identify which hierarchical partition key path to use when adding new items to the container. Which SDK class should you use?
Answer: D
You are designing an Azure Cosmos DB for NoSQL data model that will contain authors, books the authors have written, and reviews of the books. You need to maintain referential integrity between entities by using server-side transactional support. What is the largest scope of the transactions you can use?
Answer: D
