Exam AZ-800 topic 3 question 13 discussion

HOTSPOT -
You plan to deploy an Azure virtual machine that will run Windows Server. The virtual machine will host an Active Directory Domain Services (AD DS) domain controller and a drive named F: on a new virtual disk.
You need to configure storage for the virtual machine. The solution must meet the following requirements:
* Maximize resiliency for AD DS.
* Prevent accidental data loss.
How should you configure the storage? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:

Suggested Answer:
Box 1: F -
Create a separate virtual data disk for storing the database, logs, and sysvol folder for Active Directory. Do not store these items on the same disk as the operating system.

Box 2: None -
By default, data disks that are attached to a VM use write-through caching. However, this form of caching can conflict with the requirements of AD DS. For this reason, set the Host Cache Preference setting on the data disk to None.
