Hello Team,

Thank you for your help. And thank you for these courses.

I think that the following exam question's answer is incorrect. Please review this screenshot and let me know if you come to the same conclusion.

I see that someone else here posted this same thing back in 2023, but I do not see a reply to their question.

Thank you again.

Thanks,

Justin
