WebCorrect option is D) TRAP has the highest priority and vectors interrupt. Edge and level triggered means that the TRAP must go high and remain high until it is acknowledged. … As an example of one of the more elaborate IPL-handling systems ever deployed, the VAX computer and associated VMS operating system supports 32 priority levels, from 0 to 31. Priorities 16 and above are for requests from external hardware, while values below 16 are available for software interrupts (used internally by the operating system to schedule its own activities). Not all values are actually used, but here are some of the more important ones:
