A library defines a hierarchy: class AppError(Exception), class ConfigError(AppError), class DBError(AppError). A caller wants to catch any application-specific error but still be able to distinguish ConfigError from DBError for logging. Which except clause structure achieves this?

except AppError as e: if isinstance(e, ConfigError): log("config") elif isinstance(e, DBError): log("db")

except ConfigError: pass except DBError: pass

except (ConfigError, DBError) as e:

What effect does `raise NewException from None` have on exception chaining?

It prevents the exception from being caught by any except block

It sets `__context__` to None but keeps the original exception visible

It sets `__cause__` to None and suppresses the display of the original exception context

It raises the exception without any traceback

In Python, when an exception is raised, what is the exception itself?

An instance of an exception class

A string containing the error message

A special dictionary of error details

Which syntax explicitly chains an exception and sets the `__cause__` attribute?

raise NewException, original_exception

raise NewException with original_exception

raise NewException(original_exception)

raise NewException from original_exception

Part of the Advanced Object-Oriented Programming domain, which accounts for 35% of the PCPP-32-1 exam. Python Institute does not publish an official question count, but from its 65-minute exam (~25–45 total, ~9–16 in this domain), expect 1–1 from this objective — we provide 18 practice questions to prepare you well beyond it.
