offset=1, limit=50
Why wrong: offset=1 would skip only one item.
- B
offset=50, limit=50
Correct: skip first 50 items.
- C
offset=50, limit=100
Why wrong: Limit=100 changes page size, not standard.
- D
offset=0, limit=100
Why wrong: This would get the first 100 items, not the next page.

200-901 Understanding and Using APIs Practice Question
This 200-901 practice question tests your understanding of understanding and using apis. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A REST API uses offset and limit parameters for pagination. If the first request returns items 0-49 with limit=50 and offset=0, how should the next request be constructed to get the next page?

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
offset=50, limit=50
Option B is correct because pagination with offset and limit works by advancing the offset by the limit value to fetch the next set of items. The first request returned items 0-49 (offset=0, limit=50), so the next request should start at offset=50 with the same limit=50 to retrieve items 50-99. This ensures no overlap and no gaps in the data.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
offset=1, limit=50
Why it's wrong here
offset=1 would skip only one item.

- ✗
offset=50, limit=100
Why it's wrong here
Limit=100 changes page size, not standard.
- ✗
offset=0, limit=100
Why it's wrong here
This would get the first 100 items, not the next page.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates mistakenly think offset should be incremented by 1 (like a page number) rather than by the limit value, leading them to choose offset=1 instead of offset=50.
Detailed technical explanation
How to think about this question
In REST API pagination, the offset parameter specifies the starting index (0-based) within the total result set, and limit defines the maximum number of items per page. This pattern is commonly used with SQL's OFFSET and LIMIT clauses, where the next offset is calculated as current_offset + limit. A real-world scenario is when an API returns a large dataset (e.g., 10,000 records) and the client must iterate through pages without missing or duplicating records, which is critical for data consistency in reporting or synchronization tasks.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 200-901 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
