You want to limit the memory, CPU, and network utilization of a set of processes running on a Linux host.Which Linux feature would you configure in this scenario?
Answer(s): D
Control groups (cgroups) is a Linux kernel feature that limits, accounts for, and isolates the CPU, memory, disk I/O, and network usage of one or more processes. It allows you to allocate resources among user-defined groups of processes running on a system. You can monitor the groups of processes, deny the groups of processes access to certain resources, or even freeze groups of processes.
