Drag and Drop Question
You are planning an SAP on Azure deployment that will contain instances of SQL Server on Azure Virtual Machines.
Each virtual machine will contain a data file disk and a log file disk.
You need to recommend a host caching solution.
Which host caching setting should you recommend for each disk? To answer, drag the appropriate settings to the correct targets. Each setting 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.

Box 1: Read-only
Data file disk
Storage: Performance best practices for SQL Server on Azure VMs
Data file caching policies
Your storage caching policy varies depending on the type of SQL Server data files that are hosted on the drive.
The following table provides a summary of the recommended caching policies based on the type of SQL Server data:
* Data disk
Enable Read-only caching for the disks hosting SQL Server data files.
Reads from cache will be faster than the uncached reads from the data disk.
Box 2: None
Log file disk
* Transaction log disk
Set the caching policy to None for disks hosting the transaction log. There's no performance benefit to enabling caching for the Transaction log disk, and in fact having either Read-only or Read/Write caching enabled on the log drive can degrade performance of the writes against the drive and decrease the amount of cache available for reads on the data drive.

Explanation:
Box 1: Azure Site Recovery
Microsoft Azure Site Recovery (ASR) now supports SUSE Linux Enterprise Server 11 SP3/SP4 and SUSE Linux Enterprise Server 12 SP1/SP2/SP3. This is great for customers that are planning to migrate systems to Microsoft Azure or customers who need to have a business continuity strategy for their Azure deployments.
Azure Site Recovery enables SUSE customers to migrate their non-Azure virtual machines or physical servers to Microsoft Azure virtual machines.
Box 2: System Copy for SAP Systems
