Case Study 5 - ADatum Corporation
Overview
ADatum Corporation is a financial services company that has a main office in New York City.
Existing Environment
Licensing Agreement
ADatum has a Microsoft Volume Licensing agreement that includes Software Assurance.
Network Infrastructure
ADatum has an on-premises datacenter and an Azure subscription named Sub1.
Sub1 contains a virtual network named Network1 in the East US Azure region.
The datacenter is connected to Network1 by using a Site-to-Site (S2S) VPN.

The forest contains a single domain named corp.adatum.com.
The corp.adatum.com domain syncs with a Microsoft Entra tenant named adatum.com.
Database Environment
The datacenter contains the servers shown in the following table.
DB1 and DB2 are used for transactional and analytical workloads by an application named App1.
App1 runs on Microsoft Entra hybrid joined servers that run Windows Server 2022. App1 uses Kerberos authentication.
DB3 stores compliance data used by two applications named App2 and App3.
DB3 performance is monitored by using Extended Events sessions, with the event_file target set to a file share on a local disk of SVR3.

Business Requirements
ADatum identifies the following business requirements:
- Minimize costs whenever possible, without affecting other requirements.
- Minimize administrative effort.
You need to recommend a solution to ensure that the performance of DB3 is optimized after the migration to Azure SQL Database. The solution must meet availability requirements.

Answer:
Explanation:
Section: [none]
Explanation:
Box 1: adf_publish
By default, data factory generates the Resource Manager templates of the published factory and saves them into a branch called adf_publish. To configure a custom publish branch, add a publish_config.json file to the root folder in the collaboration branch. When publishing, ADF reads this file, looks for the field publishBranch, and saves all Resource Manager templates to the specified location. If the branch doesn't exist, data factory will automatically create it. And example of what this file looks like is below:
{
"publishBranch": "factory/adf_publish"
}
Box 2: /dwh_barchlet/ adf_publish/contososales
RepositoryName: Your Azure Repos code repository name. Azure Repos projects contain Git repositories to manage your source code as your project grows. You can create a new repository or use an existing repository that's already in your project.

NEW QUESTION # 48
You plan to create a table in an Azure Synapse Analytics dedicated SQL pool.
Data in the table will be retained for five years. Once a year, data that is older than five years will be deleted.
You need to ensure that the data is distributed evenly across partitions. The solutions must minimize the amount of time required to delete old data.
How should you complete the Transact-SQL statement? To answer, drag the appropriate values to the correct targets. Each value may be used once, more than once, or not at all.
You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Box 1: HASH
Box 2: OrderDateKey
In most cases, table partitions are created on a date column.
A way to eliminate rollbacks is to use Metadata Only operations like partition switching for data management.
For example, rather than execute a DELETE statement to delete all rows in a table where the order_date was in October of 2001, you could partition your data early. Then you can switch out the partition with data for an empty partition from another table.
