Debug support mechanish is used for :
-
Fault finding only
-
Fault corrections only
-
Fault finding and fault corrections
-
Load sharing
Debug support mechanisms are designed to assist developers in both identifying and fixing faults in software systems. The process involves first detecting the issue (fault finding) and then implementing a solution (fault correction). Options A and B are incomplete as they only cover one aspect of the debugging process, while option D (load sharing) is unrelated to debugging functionality.
A debug support mechanism provides the tools and hooks (breakpoints, tracing, logging) that let developers both locate the source of a fault and then apply corrections, making it useful for the entire fix cycle, not just detection. It's unrelated to system load balancing, which is a separate operational concern.
