Exchange 2016: setup tried to install wrong CU version

Recently faced an interesting feature on the start at installation of Cumulative Update.

When starting CU setup from the command line, the installation of the current version can start.

An example:
[PS] C:\Windows\system32>cd d:\
[PS] D:\>setup /PrepareSchema
Microsoft Exchange Server 2016 Cumulative Update 6 Unattended Setup

Exchange 2016: Do I need update AD schema?

Not each Cumulative Update of Microsoft Exchange 2016 contains updates to the AD schema. I decided to present it in the simple table.
Hope it will useful to someone.
