Step-by-step explanation:
Option D. Install Remote Server Administration Tools on Windows 10 is the correct answer. To manage user objects in the domain, John needs to have the Active Directory Users and Computers snap-in on his Windows 10 workstation. This can be achieved by installing the Remote Server Administration Tools (RSAT), which includes the Active Directory tools.
Once RSAT is installed, John can run ‘dsa.msc’ in the Run dialog box to open Active Directory Users and Computers. He will then be able to manage user objects in the domain as per the permissions granted to the TechSupport security group.
To enable John to manage user objects in the domain from his Windows 10 workstation, the correct action would be to install Remote Server Administration Tools (RSAT) on Windows 10.
This toolset includes the Active Directory Users and Computers snap-in, which is necessary for managing domain user objects. Once RSAT is installed, John will be able to access Active Directory Users and Computers directly from his management workstation.
