Explanation:

In Windows Server container deployments, the isolation mode determines kernel compatibility between the host and the container image. The Administering Windows Server Hybrid Core Infrastructure materials explain that Windows Server containers using process isolation share the host kernel and therefore require the container image to match the host's OS version/build. The guide contrasts this with Hyper-V isolation, stating that each container runs inside a lightweight utility VM: "Hyper-V isolated containers do not share the host kernel; they provide a separate kernel instance, allowing containers built on a different Windows build (or earlier Windows Server version) to run on a newer host." Because Host1 is Windows Server 2022 and image1 is based on Windows Server 2019, process isolation would fail due to the version mismatch. The documented remediation is to start the container with Hyper-V isolation, which decouples the container from the host's kernel requirements. The study guide shows this operationally with Docker: "Use docker run ... --isolation=hyperv when the container base image version differs from the host." Therefore, to successfully start the container on Host1, you must use the Docker CLI with Hyper-V isolation:
Docker run -d --isolation=hyperv image1.
