3 - If the current module does not know what to do, it can either return an error code to caller (and log an error), or pass local error info along with error to upper call. If nobody knows what to do with the data, we don't crash the program, but finish with error.
1 (An error (or other fault)) is too generic.
Errors can occur at any time, suppose you read a JSON (last of my examples) but the file is not ANSI, but UTF-8. This (Jansson's json_loadf, for clarity) is not an exception, it simply means "we do not know how to read BOM marker".
Fault - depends what do you mean. If fault means program flow disruption or program starting affecting other unrelated data, it is an exception (that's why KeBugCheckEx exists).
2 - Equally valid responses can exists. Suppose you need to do two allocations and either can fail with ENOMEM. The result is indeed ENOMEM, but we don't know which one failed. And we do not need to know - ENOMEM is enough. (Not sure if this was a good example, though).
