It is really sad that the first two questions on the test go over items that aren’t even covered in the course material or are vague at best.
Fails and incorrect are both the same… So… What is meant in the distinction of fail and incorrect? If it is incorrect it fails… if it fails it is incorrect. Very poor wording of the potential answers.
Question one talks about the $geoNear… I went back into the course and I didn’t see any detailed description of the geoNear operator… I may have missed it, but I didn’t see it. I looked it up in the MongoDB Docs and there is no mention of the ability to project or not project… So… Again Frustrating
I was also under the impression from the documentation that you can only have one $facet stage… Is this correct or not? From MongoDB documentation on $facets:
Other aggregation stages can also be used with $facet with the following exceptions: $collStats $facet $geoNear $indexStats $out $merge $planCacheStats
So… Again really confusing when it comes to the test.
Again bad use of the word fail and incorrect. This is just plain frustrating.
Gave up on question 7 cause I have no chance of passing… Will just retake the course when it is available for retake.
