On your first day at MDFT Pro, a well-known training agency, you are helping migrate from an on-premises Dynamics 365 installation to a Power Platform solution. You are creating plug-ins for the new solution.
You need to register the plug-ins.
Which isolation mode should you use?
None is incorrect. None isolation mode is not supported in Power Platform - only for on-premises.
Disk is incorrect. Disk isolation mode is only for on-premises deployments, not cloud.
Global Assembly Cache (GAC) is incorrect. GAC (Global Assembly Cache) is only for on-premises Dynamics 365 deployments.
Sandbox is correct. Sandbox isolation mode is required for Power Platform plug-ins to ensure security and prevent server crashes.
