As all previous comments suggest, you should catch all the "known" exceptions with exception specific catch block and other unknown, or more appropriately, all "unmatched" exceptions with catch (Exception ex) { ... } or just catch { ... }

However, as specified in your code, you are handling all kind of exceptions in same way. So in this particular case, the output (what you are calling Fault Tolerance) will be the same, but the performance will improve (since the runtime need not compare exception type with given list of types).

Moral of the story : Use single common try-catch in this particular case. But in general, avoid such habit.
