That depends on the weight load, the air temperature, and when the failure occurs.
If you take off (climb) and you turn (bank) and one engine fails, you can be in a non-recoverable position. It depends a lot on which engine. The laws of physics and aerodynamics rule over certifications.
The key with a prop is to get the dead engine’s prop to feather, otherwise it’s a lot of drag.
One engine out on takeoff is probably the most trained for and practiced problem.
