7. Once you have installed Docker, how many networks are created automatically? A. 1 B. 2 C. 3 D. 4

C. 3 Once you have installed Docker, there will be three networks that are created automatically. You can see these networks by typing docker network ls in PowerShell or at an elevated command prompt.

1. You have a Nano Server named Nano1. You deploy several containers to Nano1 that use an image named Image1. You need to deploy a new container to Nano1 that uses Image1. What should you run? A. Install-NanoServerPackage cmdlet. B. Install-WindowsFeature cmdlet. C. The docker load command D. The docker run command

D. The docker run command The docker run command (along with the Options). An administrator can add to or override the image settings set by a developer.

10. What DockerFile command will allow an administrator to create a mount point and externally mounted volumes from host systems or other containers? A. Onbuild B. Run C. Expose D. Volume

D. Volume The Volume DockerFile command will allow an administrator to create a mount point and externally mounted volumes from host systems or other containers.

8. True or False: The Azure Container Service uses open-source scheduling and management tools. A. True B. False

A. True The Azure Container Service allows you to easily create, configure, and manage your virtual machine cluster of containers. By using open-source tools, the Azure Container Service connects you with thousands of other users who are also designing, building, and maintaining container images.

3. True or False: The Docker application needs to be installed to work with Windows Containers. A. True B. False

A. True The Docker application does need to be installed in order to work with Windows Containers.

5. One of the advantages of using Docker is that you can go out to Docker's website and look at the different images that are available. There are images for operating systems, applications, and software. But, what if you can't find what you are looking for? Is it possible to create your own Dockerfile? A. Yes B. No

A. Yes Yes, you can build your own images using Dockerfiles. When you install docker, the docker engine includes tools that can be used to create Dockerfiles. Dockerfiles are just text files that are manually created and they are compiled and turned into an image file.

4. What is the default setting for a container when working with the Docker Restart Policy? A. no B. on-failure[:max-retries] C. always D. unless-stopped

A. no The answer is "no." This setting will not automatically restart the container. This is the default setting for a container.

9. What PowerShell command will allow an administrator to view information about containers? A. Get-ContainerHost B. Get-Container C. Get-ContainerImage D. Get-ContainerNetworkAdapter

B. Get-Container The Get-Container PowerShell command allows an administrator to view information about containers.

2. Which container type is described? It provides application isolation through process and namespace isolation technology. This container shares a kernel with the container host and all containers running on the host. A. Hyper-V Container B. Windows Server Container

B. Hyper-V Container This container allows an administrator to isolate applications so applications can run in their own space and not affect other applications. In a Windows Server Container, the kernel is shared between all of the different Windows Containers.

6. How are Windows Containers different from Hyper-V Containers? A. There is no difference. B. Windows Containers utilize their own instance of the Windows kernel, and Hyper-V Containers share the system's kernel between all containers and the host. C. Windows Containers share the system's kernel between all containers and the host, and Hyper-V Containers utilize their own instance of the Windows kernel.

C. Windows Containers share the system's kernel between all containers and the host, and Hyper-V Containers utilize their own instance of the Windows kernel. Windows Containers share the system's kernel between all containers and the host. Hyper-V Containers are different because each Hyper-V Container utilizes its own instance of the Windows kernel.
