Explanation:
Process isolation: image1 only
Hyper-V isolation: image1, image2, image3, and image4
The Administering Windows Server Hybrid Core Infrastructure materials explain two Windows container isolation modes. For process isolation, the guide states that Windows Server containers share the host's kernel and therefore require kernel/OS-version compatibility: "Process-isolated Windows containers run directly on the host and use the host's kernel; the container image must match the host OS version/build." Because Host1 is Windows Server 2022, only a Windows Server 2022 container image can be run with process isolation. Thus, among the images shown, image1 (Windows Server 2022) is the only one eligible for process isolation; 2019 and 2016 images have kernel mismatches and cannot run in that mode.
The same materials describe Hyper-V isolation as running each container inside a lightweight utility VM: " Hyper-V-isolated containers get their own kernel inside a special VM, removing the kernel version dependency on the host." This mode "allows running different Windows versions than the host" and, when LCOW/WSL is present, it "enables running Linux containers on Windows" by supplying a Linux kernel within the utility VM. Since Host1 has the Subsystem for Linux installed, Hyper-V isolation can run Windows Server 2022, 2019, 2016 container images and also Linux containers. Therefore, to maximize isolation, you can run image1, image2, image3, and image4 with Hyper-V isolation, while process isolation is limited to image1 only.
