Question

5. Should you be concerned with issues such as unexpected data corruption or a sudden hardware register content change?

A)No since interrupt routines have always the highest priority compared to any task, we will never experience a context switch during interrupt service routines, and thus we are always protected.

B)Yes, only the protocol task can experience data corruption or an unexpected changes in registers value.

C) No, since a single protocol task is accessing these resources, we are always protected.

D) Yes, an unexpected changes in register value and data structure corruption can be experience while we are servicing the interrupt service routine.A

Explanation / Answer

Answer) B is the correct option i.e. Yes, only the protocol task can experience data corruption or an unexpected changes in registers value.

Because change in the normal values assigned to various hardware registers or data corruption may lead to changes or errors in the work which is being done. Therefore this is a thing which is to be concerned about.
