You are designing an Azure Cosmos DB database that will use the SQL API.
You have an application that will write the sale of products to the database. Before a sale is written, the application will verify whether the products in the sale exist. A typical sale includes 10 products.
You need to recommend a design for the database. The solution must minimize storage space.
What should you recommend

• A.Create a collection for products and a collection for sales. Create a document for each product in the products collection. For each sale, create a document in the sales collection that references the product documents.
• B.Create a collection for each product. In each collection, create a document for each sale of the product.
• C.Create a collection for products. For each product, create a document in the products collection that contains embedded documents for each sale of the product
• D.Create a collection for sales. For each sale, create a document in the sales collection that contains embedded documents for each product in the sale.

You are designing an Azure Cosmos DB database that will use the SQL API. The database will receive data from loT devices. The loT devices will insert documents that have the following structure.

Customer data will be recorded in the database also. The documents for the customer data have the following structure.

Most queries to the database will return loT data and will filter the results based on the date.
You need to implement a partitioning strategy that will minimize the number of request units (RUs) consumed.
What should you do?

• A.Create a collection. Set the partition key to device id. Embed the loT data into the customer data.
• B.Create a collection Set the partition key to date, Embed the lol data into the customer data.
• C.Create a collection for loT documents and a collection for customer documents. For the lol document collection, set the partition key to device id. For the customer document collection, set the partition key to id.
• D.Create a collection for loT documents and a collection for customer documents. For the lol document collection set the partition key to date. For the customer document collection, set the partition key to id.

You have an Azure Cosmos DB account named Account1. Account1 contains a database named DB1. DB1 contains a collection named Coll1. Coll1 contains a stored procedure named Sp1. Sp1 reads the data in Coll1.
You need to create a user named User1 who will have the permissions to run Sp1.
How should you complete the code? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

正解：

You are writing a NET application that will use optimistic concurrency. To update documents the application will read a document, and then write changes to the document.
You need to prevent the document from being modified if the document changed since the initial read operation.
How should you complete the code segment? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point

正解：

You have an Azure Cosmos DB account named Account1. Account1 contains a database named DB1. DB1 contains a collection named Coll1 Account has a write region of East US and a read region of West US. Coll1 contains 500,000 documents that are 1 KB each.
You have two applications named App1 and App2 that read documents from Coll1 in the East US region at a steady rate of 1,000 request units per second (RU/s). Both applications consistently throw an exception that has the 429 HTTP status code.
You need to recommend a solution to minimize the number of exceptions. The solution must minimize costs.
What should you recommend?

• A.Set the default consistency level of DB1 to Bounded Staleness
• B.increase the number of request units (RUs) for Coll1.
• C.Set the indexing mode of Coll1 to Lazy
• D.Modify the connection policy of App2
