- A
Change the endpoint to 'GET /dna/intent/api/v1/network-device' which returns all devices without pagination.
Why wrong: Incorrect. This endpoint retrieves network devices, not site health, and may also implement pagination.
- B
Export the site health data using the 'POST /dna/intent/api/v1/site-health/export' endpoint.
Why wrong: Incorrect. This is an export feature that may generate a report, not a direct retrieval of all data in a single API call.
- C
Increase the 'pageSize' parameter to 150 to retrieve all records in a single request.
Why wrong: Incorrect. The API likely has a maximum page size (e.g., 50), so requesting 150 may be rejected or truncated.
- D
Use the 'nextPageUri' field provided in the response to iterate through all pages until no more pages are available.
Correct. Following the pagination links (nextPageUri) is the standard and reliable method to retrieve all records.
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.
You are a network automation engineer using the Cisco DNA Center REST API to retrieve health scores for all sites in your network. You call the 'GET /dna/intent/api/v1/site-health' endpoint with parameters to filter by time range. The response returns only the first 20 sites out of a total of 150 sites. You notice that the response includes a 'totalRecords' field showing 150, but only 20 objects are in the 'response' array. You recall that the API documentation mentions pagination support. To avoid manually looping through all pages, you want to implement a robust solution that efficiently retrieves all site health data. Which approach should you take?

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
Use the 'nextPageUri' field provided in the response to iterate through all pages until no more pages are available.
Option D is correct because the Cisco DNA Center REST API implements pagination using a 'nextPageUri' field in the response, which provides the direct URL to the next page of results. By following this field iteratively until it is null or absent, you can efficiently retrieve all 150 site health records without manually constructing pagination parameters or looping through page numbers, ensuring a robust and maintainable solution.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Change the endpoint to 'GET /dna/intent/api/v1/network-device' which returns all devices without pagination.
Why it's wrong here
Incorrect. This endpoint retrieves network devices, not site health, and may also implement pagination.
- ✗
Export the site health data using the 'POST /dna/intent/api/v1/site-health/export' endpoint.
Why it's wrong here
Incorrect. This is an export feature that may generate a report, not a direct retrieval of all data in a single API call.
- ✗
Increase the 'pageSize' parameter to 150 to retrieve all records in a single request.
Why it's wrong here
Incorrect. The API likely has a maximum page size (e.g., 50), so requesting 150 may be rejected or truncated.
- ✓
Use the 'nextPageUri' field provided in the response to iterate through all pages until no more pages are available.
Why this is correct
Correct. Following the pagination links (nextPageUri) is the standard and reliable method to retrieve all records.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that you can simply increase the 'pageSize' parameter to retrieve all records at once, but the trap is that API endpoints enforce a maximum page size, and the correct pattern is to use the provided 'nextPageUri' field to iterate through pages.
Detailed technical explanation
How to think about this question
Under the hood, Cisco DNA Center's pagination mechanism uses cursor-based or offset-based pagination where the 'nextPageUri' field contains a fully qualified URL with precomputed query parameters (e.g., offset and limit) for the next page. This approach avoids race conditions when data changes between requests, as the server manages the state. In real-world scenarios, network automation scripts must handle pagination gracefully to avoid incomplete data collection, especially when monitoring large-scale networks with hundreds of sites.
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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
