Your organization has an Azure Virtual Desktop host pool. You have been asked to install MS Antimalware for Azure on the session hosts. How would you accomplish the requirement?

Answer options:

A.Activate Windows 10 security features using a Group Policy Object (GPO).
B.Add an extension for each session host.
C.Install a Windows feature by signing-in to each session host.
D.For the host pool, configure the RDP Properties.

Correct Answer: B 
Microsoft Antimalware is not by default installed in the VMs platform and is available as an additional/optional feature through Visual Studio and Azure portal Virtual Machine configuration under Security Extensions.
Option A is incorrect. Activating Windows 10 security features using a Group Policy Object (GPO) won’t help in installing MS Antimalware.
Option B is correct. You need to add a security extension for every session host to install the MS Antimalware.
Option C is incorrect. Installing a Windows feature won’t help in meeting the requirements.
Option D is incorrect. Configuration of the RDP Properties for the host pool won’t help you meet the requirements.
