      Overview -

      ADatum Corporation is a retailer that sells products through two sales channels: retail stores and a website.

      Existing Environment -

      ADatum has one database server that has Microsoft SQL Server 2016 installed. The server hosts three mission-critical databases named SALESDB, DOCDB, and REPORTINGDB.

      SALESDB collects data from the stores and the website.

      DOCDB stores documents that connect to the sales data in SALESDB. The documents are stored in two different JSON formats based on the sales channel.

      REPORTINGDB stores reporting data and contains several columnstore indexes. A daily process creates reporting data in REPORTINGDB from the data in

      SALESDB. The process is implemented as a SQL Server Integration Services (SSIS) package that runs a stored procedure from SALESDB.

      Requirements -

      Planned Changes -

      ADatum plans to move the current data infrastructure to Azure. The new infrastructure has the following requirements:

      Migrate SALESDB and REPORTINGDB to an Azure SQL database.

      Migrate DOCDB to Azure Cosmos DB.

      The sales data, including the documents in JSON format, must be gathered as it arrives and analyzed online by using Azure Stream Analytics. The analytics process will perform aggregations that must be done continuously, without gaps, and without overlapping.

      As they arrive, all the sales documents in JSON format must be transformed into one consistent format.

      Azure Data Factory will replace the SSIS process of copying the data from SALESDB to REPORTINGDB.

      Technical Requirements -

      The new Azure data infrastructure must meet the following technical requirements:

      Data in SALESDB must encrypted by using Transparent Data Encryption (TDE). The encryption must use your own key.

      SALESDB must be restorable to any given minute within the past three weeks.

      Real-time processing must be monitored to ensure that workloads are sized properly based on actual usage patterns.

      Missing indexes must be created automatically for REPORTINGDB.

      Disk IO, CPU, and memory usage must be monitored for SALESDB. Question Which windowing function should you use to perform the streaming aggregation of the sales data?


      Answer: D
  • Question 3
    • You are designing an enterprise data warehouse in Azure Synapse Analytics that will contain a table named Customers. Customers will contain credit card information.

      You need to recommend a solution to provide salespeople with the ability to view all the entries in Customers. The solution must prevent all the salespeople from viewing or inferring the credit card information.

      What should you include in the recommendation?


      Answer: B
  • Question 4
    • Your organization wants to deploy a SQL Server HA/DR solution in Azure. They have the following requirements:

      Automatic failover without manual intervention.

      Read and write operations should be possible on the primary replica, while only read operations should be allowed on the secondary replica.

      Both primary and secondary replicas must reside in different Azure regions for disaster recovery purposes.

      Which of the following configurations meets all the provided requirements?


      Answer: A
  • Question 5
    • You have an Azure virtual machine named VM1 that runs Windows Server 2022 and hosts a Microsoft SQL Server 2019 instance named SQL1.

      You need to configure SQL1 to use mixed mode authentication.

      Which procedure should you run?


      Answer: B
