View Answer

Answer: B

Explanation:

= The role of Control Groups (cgroups) when used with a Docker container is not user authorization to the Docker API. Cgroups are a feature of the Linux kernel that allow you to limit the access processes and containers have to system resources such as CPU, RAM, IOPS and network1. Cgroups enable Docker to share available hardware resources to containers and optionally enforce limits and constraints2. User authorization to the Docker API is a different concept that involves granting permissions to users or groups to perform certain actions on the Docker daemon, such as creating, running, or stopping containers3.
