What is a primary use case for the insertMany() method?

The insertMany() method in MongoDB is specifically designed to facilitate the insertion of multiple documents into a collection in a single operation. This method streamlines the process of adding a batch of records, which can significantly enhance performance and efficiency compared to inserting documents one at a time.

When using insertMany(), you can provide an array of documents to be added to the collection, enabling you to execute bulk operations seamlessly. This is particularly valuable in scenarios where many records need to be inserted simultaneously, as it minimizes the number of network requests and optimizes data throughput.

In contrast, the other options address functionalities that are not part of what insertMany() is intended for. For instance, updating records, finding specific records based on conditions, or deleting records requires different methods that are specialized for those tasks. Hence, the primary use case of insertMany() is precisely to add multiple records efficiently, confirming that it is indeed the correct choice for this question.
