Good question, poor title.
The question is explicitly about constraints:
Is it possible to create a table with unique constraint ....
and the title is too. So why is the question good if the title is poor?
Anyway, there's nothing wrong with the question or indeed with the answer (the answer is correct), it's just that the explanation (not the answer) is about indexes, not about constraints.
=> If you ask about constraints I think in constraints.
=> If you ask about indexes I think in indexes.
But if you ask about vacations I think that it's time to take on 😛
On those pointes I definitely agree!
