[All 101-500 Questions]

Which of the following statements are correct when comparing Linux containers with traditional virtual machines (e.g. LXC vs. KVM)? (Choose three.)

  • A. Containers are a lightweight virtualization method where the kernel controls process isolation and resource management.
  • B. Fully virtualized machines can run any operating system for a specific hardware architecture within the virtual machine.
  • C. Containers are completely decoupled from the host system's physical hardware and can only use emulated virtual hardware devices.
  • D. The guest environment for fully virtualized machines is created by a hypervisor which provides virtual and emulated hardware devices.
  • E. Containers on the same host can use different operating systems, as the container hypervisor creates separate kernel execution.

I remember that if you are running an Window OS in your host, you are only able to run "flavors" of Windows OS (things that are based on Windows OS). Another example is if you run your host OS on Ubuntu, then you will be able to run RHEL and CentOS in your containers but not Window OS. Apologies if I am incorrect but that is what my hypothesis is.

E is not correct because containers do not use hypervisors.

A, B, and D are right. C is traditional KVM With E, yes if hypervisor was replaced with container namespace and the same kernel execution were referenced, then this would be accurate. So choice E is wrong. However, LXC does focus on OS containerization and the goal is to not need a separate kernel. https://linuxcontainers.org/lxc/manpages/man5/lxc.container.conf.5.html
