Lower level interrupts can be disarmed
and/or armed by software.
1 . T r ue
All of the following interrupts cannot
usually be locked out by software except
1. Power fault
2. External interrupt

following methods can be used to retain
multiple interrupt codes of the same class?
1. Interrupt stack only
2. Interrupt queue only
3. Both interrupt stack and queue
4. Index registers
For an interrupt signal in a particular class
to be indicated to the CPU, what minimum
number of interrupts must be present?
1 . O n e
A. Terminate current program execution
B. Lock out all interrupts
C. Store program and register data
D. Retrieve interrupt processor data
E. Enter executive state and enable desired
F. Execute interrupt processor program
G. Return to original process

New interrupts are locked out to protect the
integrity of the process that ensures
returning to the same conditions after
processing the interrupt.
