A specific scheduling mechanism uses a periodic task to check the load on each CPU and if it finds an imbalance it will distribute processes around so that the load becomes balanced. This technique is called _____. push migration redistribution process affinity run queue balancing pull migration A task (currently running) from the default scheduling class on a Linux OS running the Completely Fair Scheduler will be preempted from the CPU when ___ a task from the real-time scheduling class becomes runnable its virtual runtime attribute becomes greater than the virtual runtime for another task that has just become runnable its nice value is reduced by a negative (
