Why not CMD + ENTRYPOINT?

CMD doesn't run powershell command when container is built. It only runs command when container starts. https://goinbigdata.com/docker-run-vs-cmd-vs-entrypoint/

CMD and ENTRYPOINT differ only slightly, and are run in the runtime. The requirement is to run the powershell script during build, hence RUN.

Don't think so... there is no base-image, plus the EXPOST command should have this syntax: EXPOSE <port> [<port>/<protocol>...] but it is incorrect here

The last command will be used to run the application when the container starts up. We have to use the ENTRYPOINT command for this. So the correct answer is- FROM > WORKDIR > COPY > CMD/ENTRYPOINT

This can NOT be the Entrypoint, because the question stated that it must run the setupScript.ps1 when container is built, to do that, it must be the option with RUN CMD and Entrypoint are similar, they both execute when container starts. The only difference is CMD will be ignored if you execute the container with a command specified; however Entrypoint won't be ignored.

It's asking for four Docker commands, not to choose four options. "The Docker document must be created in the same folder where ContosoApp.dll and setupScript.ps1 are stored" -> This means WORKDIR is not needed. Solution: FROM COPY RUN CMD
