Refer to the exhibit.

A is correct because if no client update time is specified on EMS, the user will be able to choose the time of installation if they wish to delay. This is because the FortiClient EMS server will not force the installation on the client.

E is correct because the Windows clients only require "File and Printer Sharing" allowed and the rest is handled by Active Directory group policy. This is becausethe Active Directory group policy will configure the Windows clients to automatically install FortiClient and the FortiClient EMS server will only need to push the initial configuration to the clients.

The other options are incorrect. Option B is incorrect because a client can only be eligible for one enabled configuration on the EMS server. Option C is incorrect because you can deploy initial installations to both Windows and macOS clients. Option D is incorrect because you can use the included SQL Server Express to deploy FortiClient EMS.
