Original issue - typo: All unsharded collection should be All unsharded collections.
What happens to unsharded collections in sharded databases?
In the current implementation, all databases in a sharded cluster have a “primary shard.” All unsharded collection within that database will reside on the same shard.

However looking deeper, the v3.2 FAQ does not have this question at all.
https://docs.mongodb.com/v3.2/faq/sharding/
It looks like there were some changes in the 3.2 Release Notes:
https://docs.mongodb.com/manual/release-notes/3.2/#sharded-cluster-enhancements
In any case it would be nice if we can get some clarity on this so the Lecture Notes (and quiz) for M102 Week 6 - "Enable Sharding for a Collection" could be updated.
Feel free to split this latter part off into multiple issues if appropriate
cross@mongodb.com from the M102 Intro to Week 1 video, or other #edu team members might be interested.
