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 counter should you monitor for real-time processing to meet the technical requirements?

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.

After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.

You have two Azure SQL Database servers named Server1 and Server2. Each server contains an Azure SQL database named Database1.

You need to restore Database1 from Server1 to Server2. The solution must replace the existing Database1 on Server2.

Solution: You restore the backup for Database1 from Server1 to the Server2 by using the RESTORE Transact-SQL command with the REPLACE option.

Does this meet the goal?

You have SQL Server on an Azure virtual machine that contains a database named DB1. DB1 contains a table named CustomerPII.

You need to record whenever users query the CustomerPII table.

Which two options should you enable? Each correct answer presents part of the solution.

NOTE: Each correct selection is worth one point.

You receive numerous alerts from Azure Monitor for an Azure SQL Database instance.

You need to reduce the number of alerts. You must only receive alerts if there is a significant change in usage patterns for an extended period.

Which two actions should you perform? Each correct answer presents part of the solution.

NOTE: Each correct selection is worth one point.
