A developer wants to build and run Linux containers on a Windows Server 2022 machine that will also host Windows containers. The developer prefers to use Docker commands directly from PowerShell. The machine currently has Docker Desktop installed but WSL is not enabled. What should you do to support Linux containers?

Install the Containers feature and switch Docker Desktop to Windows containers mode.

Enable the Virtual Machine Platform feature and install the Docker Engine directly on Windows Server.

Install a Linux distribution from the Microsoft Store and run docker commands inside that distribution.

Enable the Windows Subsystem for Linux feature, install a WSL2 kernel, and set Docker Desktop to use the WSL2 backend.

You are building a Windows container image for an app that requires the .NET Framework 4.8 and also needs to run on Windows Server 2019 and 2022 hosts. You need to ensure the image is compatible with both host OS versions. What should you do?

Use a Windows Server Core image with the .NET Framework 4.8 and rely on compatibility mode.

Use a multi-arch manifest that references both ltsc2019 and ltsc2022 images.

Build two separate images, one for ltsc2019 and one for ltsc2022, and tag them appropriately.

Build the image on Windows Server 2019 and run it on both hosts.

A developer created a Dockerfile for a Windows container image. The image builds successfully, but when the container runs, the application cannot find a required DLL. The DLL is installed by an MSI package that is copied into the image. What is the most likely cause?

The Dockerfile uses the wrong shell syntax.

The container is running in process isolation mode.

The container is using the wrong base image version.

The MSI was copied but not executed during the image build.
