The operating system that supports container-based virtualization is the ____ OS.

The operating system that supports container-based virtualization is the ____ OS.

• A. Linux
• B. Windows
• C. Host
• D. Client

Answer: (C)

Container-based virtualization runs on top of the host operating system. Containers share the host’s kernel and use OS features like namespaces and cgroups to isolate processes, rather than running a separate operating system inside each container. The host OS provides the underlying resources (CPU, memory, I/O) and the container runtime that manages all containers. While Linux or Windows can serve as the host OS, the essential term that fits the blank is the host OS because it’s the system that supports and manages the containers.
