What happens if you attempt to perform a Docker build based on an image that has not been previously referenced on your machine?

Не верно!

Docker will look at the local image repository when a container image is referenced in a Dockerfile. If one is not found on the host, Docker will search for an image with the same name and version number on Docker Hub.

At the OS level, the goal of independent application execution and failure isolation is achieved through the use of:

Верно!

Не верно!

Namespaces make the isolation of the process that runs a Docker container possible.

Control groups are what make it possible to limit the amount of CPU time and memory allocated to a given container.

Security groups are typically associated with AWS configurations, and Kubernetes is a container orchestration tool.

The history of application containerization is intimately tied to which OS?

Не верно!

Linux added two features to its kernel, namely control groups and namespaces, that made it possible to run software in isolated containers. These two changes made the container revolution possible.

A Docker container is often described as an improvement over what other technology?

Не верно!

Docker containers are often compared to VMs, as both provide the ability to deploy and run multiple, independent applications on the same physical machine.

Docker containers are less resource intensive, as they provide process-level virtualization as opposed to full OS virtualization provided by a VM, which is one of the reasons the industry has shifted toward containers.
