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.
NEW QUESTION # 65

NEW QUESTION # 66
You have SQL Server on an Azure virtual machine named SQL1.
SQL1 has an agent job to back up all databases.
You add a user named dbadmin1 as a SQL Server Agent operator.
You need to ensure that dbadmin1 receives an email alert if a job fails.
Which three actions should you perform in sequence? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct order.
Answer:
Explanation:
Explanation
Step 1: Enable the email settings for the SQL Server Agent.
To send a notification in response to an alert, you must first configure SQL Server Agent to send mail.
Step 2: Create a job alert
Step 3: Create a job notification
Example:
-- adds an e-mail notification for the specified alert (Test Alert)
-- This example assumes that Test Alert already exists
-- and that Francois Ajenstat is a valid operator name.
USE msdb ;
GO
EXEC dbo.sp_add_notification
@alert_name = N'Test Alert',
@operator_name = N'Francois Ajenstat',
@notification_method = 1 ;
GO

NEW QUESTION # 67
Hotspot Question
You have an Azure subscription.
You need to deploy two virtual machines named VM1 and VM2 that will host Microsoft SQL Server instances. The solution must meet the following requirements:
- VM1 must provide the highest I/O throughput-to-vCore ratio.
- VM2 must provide the highest memory-to-vCore ratio.
Which series should you select for each virtual machine? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Box 1: Ebdsv5-series
VM1 must provide the highest I/O throughput-to-vCore ratio.
Consider the following VM series based on your SQL Server workloads:
High I/O throughput-to-vCore ratio: The Mbsv3 and Mbdsv3-series VMs offer the highest throughput-to-vCore ratio of any VM series in any cloud. The Ebdsv5-series VMs offer the second highest throughput-to-vCore ratio in Azure. If you don't know the I/O requirements for your SQL Server workload, the Ebdsv5-series VMs is the one most likely to meet your needs.
Box 2: Mv2 series
VM2 must provide the highest memory-to-vCore ratio.
The Azure Virtual Machine Mv2 series offers the highest memory-to-vCore ratio among Azure VM sizes. These VMs are specifically designed for memory-intensive workloads like in-memory databases and large-scale analytics, providing up to 12TB of memory with a substantial number of vCPUs.

NEW QUESTION # 68
You have an Azure SQL database named DB1 that contains a table named Orders. The Orders table contains a row for each sales order. Each sales order includes the name of the user who placed the order.
You need to implement row-level security (RLS). The solution must ensure that the users can view only their respective sales orders.
What should you include in the solution? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Basic Concept: This question tests secure database administration, where the control must match the data state, access boundary, identity model, or compliance requirement.
Why the selected answer is Correct: The selected values fit this scenario because they apply the required Azure SQL configuration at the correct scope and sequence: You need to implement row-level security (RLS).
Why the alternate choices are Wrong: The alternate selections apply to different administrative stages or different scopes. In a hotspot or drag-drop task, order and scope are part of the answer, so a technically valid Azure feature can still be wrong if it is placed in the wrong step.
