The Answer is B and C:
CPU scheduler has multiple functions
- Schedules virtual CPUs (vCPUs) on physical CPUs
- Enforces the proportional-share algorithm for CPU Usage - which vCPUs will be scheduled over others
- Supports symmetric multiprocessing (SMP) VMs - up to 128 vCPUs per VM
- Uses relaxed co-scheduling for SMP VM
- The CPU scheduler chooses which world to schedule on a processor
The Answer is B and C

The CPU scheduler uses a 50-millisecond time slice called “quantum”.
This is the amount of time a vCPU can run on a pCPU before another vCPU of same priority gets scheduled.
The CPU scheduler determines which worlds are entitled to CPU time. The state and priority of a world depends on if it is consuming CPU time.
