You have a server named Server1 that runs Windows Server 2012 R2.
An administrator creates a quota as shown in the Quota exhibit. (Click the Exhibit button.)
You run the dir command as shown in the Dir exhibit. (Click the Exhibit button.)
You need to ensure that D:\Folder1 can only consume 100 MB of disk space.
What should you do?
A
1. In Quota Management, click the Quota Templates node.
2. In the Results pane, select the template on which you will base your new quota.
3. Right-click the template and click Create Quota from Template (or select Create Quota from Template from the Actions pane). This opens the Create Quota dialog box with the summary properties of the quota template displayed.
4. Under Quota path, type or browse to the folder that the quota will apply to.
5. Click the Create quota on path option. Note that the quota properties will apply to the entire folder.
Note: To create an auto apply quota, click the Auto apply template and create quotas on existing and new subfolders option. For more information about auto apply quotas, see Create an Auto Apply Quota.
6. Under Drive properties from this quota template, the template you used in step 2 to create your new quota is preselected (or you can select another template from the list). Note that the template's properties are displayed under Summary of quota properties.
7. Click Create.
Create a new Quota on path, without using the auto apply template and create quota on existing and new subfolders.
