The column names of the index in the first option are not consistent with those in the database ("record_label_contract_start_date" and not "record_label_start_date"; "record_label_contract_end_date" and not "record_label_end_date"). For this reason I believe the correct answer is number two.

Hi Davide, Thank you for your patience! The exam has been updated and the question is now corrected. You can retake the exam in order to get a higher score. Apologies for the inconvenience Best wishes, The 365 Team

Hi Davide! Thank you very much for your reply. You are very welcome. Regarding the course exam result - thank you very much for letting us know. I will pass the issue to our Technical team and will get back to you as soon as possible. Kind regards, Martin

I would really appreciate if you could update my first score too, otherwise thank you anyway :)

Hi Davide, We looked into the matter with out technical team and unfortunately we are unable to update your first score at this time. Once an exam is submitted, the results cannot be altered any longer. We realize the sensitivity of this issue and will consider improving the scoring mechanism in order to achieve 100% fairness for all other students. In the meantime you can retake the course exam multiple times in order to get a higher score. Apologies for this inconvenience. Best wishes, The 365 Team
