You are a data engineer for your company. Your company wants to build an e-commerce site that allows vendors to sell their products online. Each vendor's product can have an arbitrary number of attributes. For example, Vendor A has a product named Bicycle Z that contains attributes Price. Description, Brand, PartNumber, and Size. Vendor B has the same product named Bicycle Z that contains attributes Price, Description, Weight, and Model. You want to implement a solution that does not restrict the product attributes that are used by each vendor. Your solution must allow you to use .NET to query product data. You need to create the appropriate data store. Solution: You create a Cosmos DB account that uses the Table API. Does this solution meet the goal?

Your company has an application for technical writers to share, review and publish exam questions. The application allows live reviews for questions and provides reports about question performance after the questions are published. All questions and reviews and stored in Azure SQL Database. Writers are able to report question metrics in an exam results table with millions of rows. Reports include the percentage of correct answers, average question rating and answer count per question. After a question is published, live reviews are disabled and previous reviews are archived in a separate database. Writers report the following performance issues with the application: • Some delays are occurring during the live reviews. • Reports are taking too long to be generated. You need to resolve the performance issues. Which two features should you use? Each correct answer presents a complete solution.
