wakeup after comparison with the clock tick

none of the above

busy looping for a specific number of clock cycles

All processes share the same memory space

All kernel processes have the same priority

All users share the same memory space

All user-space processes have the same priority

A failure of one process in user-space might cause the whole system to fail

All users have root access on the system

All services are implemented in user-space

A failure of one process in kernelspace might cause the whole system to fail

All services are implemented in the kernel

A given peripheral can use several interrupt lines

Interrupts are dispatched on any CPU

Interrupts are always originating from peripherals

A given interrupt line can be dispatched only on one CPU

An interrupt line can be shared only by peripherals of the same type

When an interrupt is being processed in interrupt context, no other interrupt can be processed on the same line

A given interrupt can be dispatched simultaneously on several CPU
