Question
What is the difference between a Docker container and a virtual machine?(1 Point)A Docker container is smaller and faster than a virtual machine.A Docker container shares the host operating system kernel, while a virtual machine has its own kernel.A Docker container uses less resources than a virtual machine.All of the above.
Solution
The difference between a Docker container and a virtual machine can be explained as follows:
-
Size and Speed: Docker containers are smaller and faster than virtual machines. This is because containers share the host system's kernel, while a virtual machine needs to run a full-blown operating system on top of the host's operating system.
-
Kernel Sharing: Docker containers share the host operating system kernel, while a virtual machine has its own kernel. This means that a Docker container can start up almost instantly, whereas a virtual machine needs to boot up the entire operating system.
-
Resource Usage: Docker containers use less resources than a virtual machine. This is because Docker containers only need to run the application and its dependencies, while a virtual machine runs the entire operating system and the application.
So, all of the above statements are correct and explain the difference between a Docker container and a virtual machine.

How do containers differ from traditional virtual machines in terms of resource efficiency, isolation, and deployment, and what are the advantages and disadvantages of using containers over VMs?(a) Containers provide complete isolation by running separate operating systems, making them more secure but less efficient than VMs.(b) Containers use less disk space and memory as they share the host OS kernel, leading to better resource efficiency and faster startup times, but offer less isolation compared to VMs, which could pose security risks.(c) Containers and VMs both offer the same level of resource efficiency and isolation, with no significant differences in deployment speed.(d) Containers are more resource-intensive than VMs as they duplicate the host OS for each container, offering better isolation but slower deployment times.(e) Containers provide the same level of isolation as VMs but require specialized hardware to run, making them less flexible in diverse environments.
What feature of containers makes them more lightweight than virtual machines?(1 Point)They do not need an operating system.They use a sandboxed operating system.All containers running on the same physical computer share the same app resources.They share the host computer’s operating system.
What is the difference between a Docker image and a Docker container?(1 Point)A Docker image is used for temporary data, while a container is used for persistent data.A Docker image is smaller than a container.A Docker image is faster than a container.A Docker image is a blueprint for a container, while a container is a running instance of an image.
