Jeanne is working as a network administrator in an IT company.

Cgroups, or control groups, are a feature of the Linux kernel that allows system administrators to allocate, limit, and monitor the resources used by sets of processes. Jeanne can use cgroups to manage and restrict access to CPU, memory, swap, block IO rates, and network resources for containers. This feature also enables the auditing of process groups, making it possible to track the resource usage and ensure that each container only uses its allocated share, preventing any single process from monopolizing system resources.

References: The functionality of cgroups is well-documented in the Linux kernel documentation and is a fundamental topic in system administration, which is relevant to the objectives of the EC-Council’s Certified Network Defender (CND) program. The use of cgroups for managing system resources is also a standard practice in Linux-based environments12.
