You have SQL Server 2019 on an Azure virtual machine that runs Windows Server 2019. The virtual machine has 4 vCPUs and 28 GB of memory.
You scale up the virtual machine to 8 vCPUs and 64 GB of memory.
You need to reduce tempdb contention without negatively affecting server performance.
What is the number of secondary data files that you should configure for tempdb?

You have an on-premises multi-tier application named App1 that includes a web tier, an application tier, and a Microsoft SQL Server tier. All the tiers run on Hyper-V virtual machines.
Your new disaster recovery plan requires that all business-critical applications can be recovered to Azure.
You need to recommend a solution to fail over the database tier of App1 to Azure. The solution must provide the ability to test failover to Azure without affecting the current environment.
What should you include in the recommendation?

Hotspot Question
You have an Azure subscription.
You plan to migrate 10 on-premises Microsoft SQL Server instances to Azure.
You need to ensure that the migrated environment can be managed by using multiserver administration and supports master/target (MSX/TSX) jobs.
The solution must minimize administrative effort.
Which SQL deployment options should you select as the master server (MSX) and the target server (TSX)? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Hotspot Question
You plan to deploy three instances of SQL Server on Azure Virtual Machines that will each contain 20 databases.
You need to recommend a solution that meets the following requirements:
- Ensures that the deployment is highly available
- Minimizes administrative effort to manage users, logins, permissions, and SQL Server Agent jobs across the instances What should you include in the recommendation? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

You have an Azure subscription that contains an Azure SQL database named DB1.
You configure a new data sync group as shown in the exhibit. (Click the Exhibit tab.)

You need to minimize how long it takes to perform the first sync.
