NEW QUESTION # 205
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.
Identity Environment
The on-premises network contains an Active Directory Domain Services (AD DS) forest.
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.
Resource allocation for DB3 is managed by using Resource Governor.
Requirements
Planned Changes
ADatum plans to implement the following changes:
- Deploy an Azure SQL managed instance named Instance1 to Network1.
- Migrate DB1 and DB2 to Instance1.
- Migrate DB3 to Azure SQL Database.
- Following the migration of DB1 and DB2, hand over database development to remote developers who use Microsoft Entra joined Windows 11 devices.
- Following the migration of DB3, configure the database to be part of an auto-failover group.
Availability Requirements
ADatum identifies the following post-migration availability requirements:
- For DB1 and DB2, offload analytical workloads to a read-only database replica in the same Azure region.
- Ensure that if a regional disaster occurs, DB1 and DB2 can be recovered from backups.
- After the migration, App1 must maintain access to DB1 and DB2.
- For DB3, manage potential performance issues caused by resource demand changes by App2 and App3.
- Ensure that DB3 will still be accessible following a planned failover.
- Ensure that DB3 can be restored if the logical server is deleted.
- Minimize downtime during the migration of DB1 and DB2.
Security Requirements
ADatum identifies the following security requirements for after the migration:
- Ensure that only designated developers who use Microsoft Entra joined Windows 11 devices can access DB1 and DB2 remotely.
- Ensure that all changes to DB3, including ones within individual transactions, are audited and recorded.
Management Requirements
ADatum identifies the following post-migration management requirements:
- Continue using Extended Events to monitor DB3.
- In Azure SQL Database, automate the management of DB3 by using elastic jobs that have database-scoped credentials.
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 meet the security requirements and the business requirements for DB3.
What should you recommend as the first step of the solution?
Answer: B
NEW QUESTION # 206
You plan to perform batch processing in Azure Databricks once daily.
Which type of Databricks cluster should you use?
Answer: C
Explanation:
Azure Databricks makes a distinction between all-purpose clusters and job clusters. You use all-purpose clusters to analyze data collaboratively using interactive notebooks. You use job clusters to run fast and robust automated jobs.
The Azure Databricks job scheduler creates a job cluster when you run a job on a new job cluster and terminates the cluster when the job is complete.
Reference:
https://docs.microsoft.com/en-us/azure/databricks/clusters
Basic Concept: This question tests configure and manage automation of tasks in the DP-300 exam context.
The correct choice is determined by the exact service boundary and operational requirement stated in the scenario.
Why A is Correct: automated can participate in administration workflows, but automation questions require the mechanism that can execute repeatable tasks with the correct scope and schedule. In this scenario, the important constraint is: Which type of Databricks cluster should you use? automated satisfies that constraint without adding an unrelated service or manual process.
Why B is Wrong: interactive can participate in administration workflows, but automation questions require the mechanism that can execute repeatable tasks with the correct scope and schedule. It would leave too much manual work or would operate at the wrong scope for the requested automation.
Why C is Wrong: High Concurrency can participate in administration workflows, but automation questions require the mechanism that can execute repeatable tasks with the correct scope and schedule. It does not provide the required repeatable execution, scheduling, or deployment automation requirement, so it would not complete the administrative workflow reliably.
NEW QUESTION # 207
You have an Azure SQL database named db1 on a server named server1.
You use Query Performance Insight to monitor db1.

NEW QUESTION # 208
You have SQL Server on an Azure virtual machine that contains a database named DB1.
The database reports a CHECKSUM error.
You need to recover the database.
How should you complete the statements? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation
Box 1: SINGLE_USER
The specified database must be in single-user mode to use one of the following repair options.
Box 2: REPAIR_ALLOW_DATA_LOSS
REPAIR_ALLOW_DATA_LOSS tries to repair all reported errors. These repairs can cause some data loss.
Note: The REPAIR_ALLOW_DATA_LOSS option is a supported feature but it may not always be the best option for bringing a database to a physically consistent state. If successful, the REPAIR_ALLOW_DATA_LOSS option may result in some data loss. In fact, it may result in more data lost than if a user were to restore the database from the last known good backup.
