Why is this answer not a correct choice for this quiz? I don’t follow.
“Creating an index with a different collation from the base collection implies overriding the base collection collation.”
See the closed topic Chapter 2 - Collations Quiz
The question is related to creating an index, not using it.
In addition, the transcript says “This way, we can create an index or name that overrides the default collation or any collection level defined collations.”
