Enter the command you would use to register dockerd.exe as a servicedockerd.exe --register-serviceYou want to be able to run a Nano Server container from a base container image that is on Docker Hub. You are ready to download the microsoft/nanoserver image from the Docker Hub website. From the drop-down list, select the command that fills in the blank:docker pullYou have pulled the microsoft/nanoserver image from the Docker Hub website. Now you need to create a new Windows Server container from the image and run the cmd command to open the command line interface in the container. From the drop-down list, select the command that fills in the blankdocker run -itYou have pulled the microsoft/nanoserver image from the Docker Hub website. Now you need to create a new Hyper-V container from the image and run the cmd command to open the command line interface in the container. From the drop-down list, select the command that fills in the blank: docker run -it microsoft/nanoserver ______________ cmd-isolation=hypervFrom the drop-down list, select the command you would use to view all running containers on the container host:docker psYou want to create a new Hyper-V container from the base container image and run the cmd command to open the command line interface in the container. However, you have not pulled the image from Docker Hub. What will happen when you run the following command: docker run -it microsoft/nanoserver -isolation=hyperv cmddocker will look for the image on your container host; if it is not there, it will pull the image from Docker Hub and create a hyper-v container.Which of the following best describes container storage?Container storage is not persistent, which is by design because containers are meant to be isolated and disposableYou are working with a container that you are using to test a new application that is under development.
