Question 1 of 7 · Ethics
You are a Professional Engineer developing an AI system for a client. The system will be used in a safety-critical application, and during testing you find behaviour that could endanger users. The client wants to stay on schedule. What should you do?
Explanation
Correct answer: A. Every Canadian engineering code of ethics puts the safety, health and welfare of the public first. That duty ranks above your duties to the client and to the schedule. You should tell the client clearly, in writing, what the risk is, and the work should not go ahead until the risk has been properly assessed and dealt with. Releasing a system with a known hazard and fixing it later leaves the public exposed. Telling your supervisor is a good step, but it does not make it acceptable to proceed with a known safety risk. A disclaimer does not remove your professional responsibility. If the client insists on proceeding, the next step is to escalate, and ultimately to report the matter to your regulator.
The real exam gives you 2.5 hours for 110 questions, about 1:22 per question on average.

How to get the most from practice questions
A practice test is a diagnostic, not a score to feel good or bad about. Three habits make the difference.
Read every explanation
Including the ones you got right. The NPPE reuses concepts in new scenarios, and knowing why an answer is right is what carries over.
Track your weak areas
Professional Practice and Law for Professional Practice together make up about half the exam, so gaps there cost the most.
Practice against the clock
The real exam is 110 questions in 2.5 hours, a little over a minute each. Timed full-length practice is the closest rehearsal you can get.
