CompTIA Security+ Exam Prep

Answer: C - When critical processes must have their functionality interrupted by another process, the interruption is done by maskable and non-maskable interrupters. A maskable interrupt is assigned to an event that may not be overly important and the programmer can indicate that if that interrupt calls, the program does not stop what it is doing. This means the interrupt is ignored. Non-maskable interrupts can never be overridden by an application because the event that has this type of interrupt assigned to it is critical.
