Stress testing is particularly useful for revealing which type of defects in distributed systems?

Logic errors in individual methods that are invisible during normal load

Defects that occur when the system is fully loaded, such as interaction defects between components that only appear under high traffic

Interface misuse defects caused by incorrect parameter types

Memory allocation bugs caused by incorrect pointer arithmetic

Correct Answer

Defects that occur when the system is fully loaded, such as interaction defects between components that only appear under high traffic

Explanation

Stress testing is particularly useful for revealing defects in distributed systems that only emerge when the system is fully loaded. Under normal load, components may interact without problems, but under stress, timing issues, race conditions, and resource contention between components may cause failures that were invisible during normal testing.
