In the context of MongoDB indexing, which of the following statements best describes the primary benefit of a compound index over multiple single-field indexes for queries that involve multiple fields?
Consider a scenario where you have a collection with documents containing a `timestamp` field and a `userId` field. You frequently query for documents within a specific time range for a particular user, e.g., `db.collection.find({ userId: "user123", timestamp: { $gte: ISODate("2023-01-01"), $lt: ISODate("2023-01-31") } })`. Which indexing strategy would be most effective for this query pattern, and why?
You are designing indexes for a collection that stores product information. Queries frequently search for products by `category` and then sort the results by `price` in ascending order, e.g., `db.products.find({ category: "electronics" }).sort({ price: 1 })`. Which of the following index definitions would be most optimal?
