Yes, it's recommended that you take the C100DBA MongoDB exam multiple times. This is because MongoDB has a few online test simulations and actual tests, and they're all very different. When taking the actual test, I recommend that you keep quiet during each question so that you can focus on answering each question looking for keywords, or looking for things like punctuation errors. The engine is a great way to practice the exam and is also the best place to discuss any pre-exam questions or concerns you may have. I think it's important to always be prepared for the exam and make sure you know all of the information needed for passing, so I would recommend that you take each practice test at least twice. The C100DBA MongoDB examination process can take up to 2 hours or more, so make sure you have plenty of time to spare. It's also recommended that you have at least 30 minutes of break time between each question so that you can relax and walk around a little bit if needed.

NEW QUESTION # 144
What is one purpose of a hidden index?
Answer: A
Explanation:
A hidden index remains physically present and continues to be maintained as documents are inserted, updated, or deleted, but the query planner does not consider that index when choosing normal execution plans. This makes hidden indexes especially useful for safely testing whether an index can be removed. An administrator can hide the index and observe production query behavior as though the index were absent. If performance or plan quality degrades, the index can be unhidden immediately without rebuilding it because MongoDB has continued to maintain it in the background. Option A is incorrect because a hidden index is still an index and is not simply removed from index statistics. Option B is also incorrect; hiding an index can actually force collection scans or alternative plans if that index was previously important. Option D misunderstands the feature entirely: hiding an index has no effect on document visibility. Hidden indexes are therefore a risk-reduction mechanism for index lifecycle management, especially before dropping an index in a production environment. Option C accurately states that purpose.
