C100DBA CRUD Operations Practice Question
When using the find() method, which cursor modifier is used to skip a specific number of documents before returning results?
⚠ Common exam trap
Candidates often confuse skip() with limit(), or believe that skip() is an efficient way to access deep pages of data, ignoring the performance cost of scanning skipped documents.

Correct answer & explanation
✓
.skip()
The skip() method is the standard cursor modifier used to bypass a set number of initial documents in a result set. It is essential for implementing pagination in applications, often used in conjunction with limit() to fetch specific pages of data. Understanding its impact on performance is vital, as skipping large numbers of documents can be expensive for the database engine to process.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
.offset()
Why it's wrong here
While some SQL databases use OFFSET, MongoDB uses the skip() cursor modifier. The offset() method does not exist in the standard MongoDB shell or drivers. Attempting to use it will result in a TypeError, as the cursor object does not contain an offset function for pagination purposes.
- ✗
.limit()
Why it's wrong here
The limit() modifier controls the maximum number of documents returned by the query, not the starting point. Using limit() alone will always start from the first document in the result set. It is often paired with skip() but serves a completely different role in the query pipeline.
- ✓
.skip()
Why this is correct
The skip() method is the correct cursor modifier to ignore a specified number of documents. It allows developers to paginate through large collections by defining the starting offset. When combined with sort() and limit(), it provides a reliable way to retrieve subsets of data for user interfaces.
- ✗
.next()
Why it's wrong here
The next() method is used to iterate through the cursor and retrieve the next available document one by one. It is not designed to skip multiple documents efficiently or support standard pagination logic. Using it in a loop to skip documents would be highly inefficient and slow.
