I passed this exam a few months back, and one thing that really boosted my confidence on exam day I actually heard in AWS training. They said that they will never put an answer referencing a made up service, they will only see if you know how to best use each service (mechanical sympathy).
So if one of the answers is AWS unicorn asteroid blaster containers, then that is a real service and not a trick question.
Moral of the story is don’t second guess yourself based on what you see during the test as they are testing you not trying to trick you.
