Unfortunately, the contents of exams and exam questions cannot be discussed as it violates the exam rules, terms, and conditions.
If you attended the training, you might reach out to the instructor, or if you have the course manual, every question in the exam should be solvable with that content. Otherwise, if you have a local Aruba SE, they may be helpful to explain things or guide you to the right place.
In case you can bend the question to a generic technology (or product) question, you can post it in the switching forum on Airheads and get the conversation going there. Just be careful with that, not to expose exam information or make others expose exam information.
