Question
A security administrator is setting up a virtualization solution that needs to run services from a single host. Each service should be the only one running in its environment. Each environment needs to have its own operating system as a base but share the kernel version and properties of the running host. Which of the following technologies would best meet these requirements?
Options
- AContainers
- BType 1 hypervisor
- CType 2 hypervisor
- DVirtual desktop infrastructure
- EEmulation

Explanation
Containers are lightweight, virtualized environments that allow multiple services to run on the same host while sharing the kernel of the host operating system. Each container runs its own application and libraries, and it behaves as if it's running in its own isolated environment. However, containers share the kernel of the host operating system, making them resource- efficient and faster to deploy compared to full virtual machines. This matches the requirement of running services from a single host, each in its own environment with its own operating system base, while sharing the kernel version and properties of the host. Unlike full hypervisors or emulation, containers do not require separate full operating systems per service, making them more efficient and suitable for this use case.
