Explanation:
ProcessA is in a container that has process isolation. So, both Container1 and the host (Server1) can see the process. Per this article "When you have a Windows container running in process isolation mode, all processes are isolated between the containers so they have no influence on each other. However, the security boundary between container host and containers is simply the process isolation itself, which means the container host has visibility into the processes running inside the container."
https://argonsys.com/microsoft-cloud/library/how-to-identify-processes-running-inside-a-windows- container-from-the-container-host/ ProcessC is in a hyper-V isolation container in contrast, so only Container3 can see the process.
So, Container1 and Server1 only for the first answer. Container3 only for the second one.
