- A
Increase the 'limit' parameter to 1000 in a single API call.
Why wrong: Incorrect because the API likely enforces a maximum limit per call, and setting it too high may result in an error or truncated data.
- B
Use the 'next' URL from the response headers to automatically fetch the next page.
Why wrong: Incorrect because the scenario states the API does not provide a 'next' link; it uses offset and limit parameters.
- C
Write a loop that increments the 'offset' parameter by the 'limit' value until all pages are retrieved.
Correct because this implements standard pagination by adjusting the offset parameter in each iteration until no more data is returned.
- D
Switch to using the Cisco DNA Center Python SDK which handles pagination automatically.
Why wrong: Incorrect because while the SDK may help, the question asks what the engineer should do with the current script, and the SDK is not the only solution.
Quick Answer
The answer is to write a loop that increments the 'offset' parameter by the 'limit' value until all pages are retrieved. This is the correct approach because the Cisco DNA Center API uses offset-based pagination, where each request fetches a fixed number of records defined by the 'limit' parameter, and the 'offset' determines the starting point for the next batch. By incrementing the offset in a loop—typically starting at 0 and adding the limit each iteration—the script systematically retrieves every page of network devices and health scores until the API returns an empty list, signaling the end of the dataset. On the ENCOR 350-401 exam, this scenario tests your understanding of REST API pagination patterns and Python scripting for network automation, a key skill in the Automation and Programmability section. A common trap is assuming a 'next' link will be provided or that increasing the limit will work, but Cisco DNA Center enforces maximum limits. Memory tip: Think of offset as your bookmark—each loop turns the page by moving the bookmark forward by the limit.
CCNP Python for Network Automation Practice Question
This 350-401 practice question tests your understanding of python for network automation. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.
An engineer is using the Cisco DNA Center REST API to retrieve a list of network devices and their health scores. The engineer writes a Python script using the requests library. The script successfully retrieves data for the first 100 devices, but when trying to get the next 100, the API returns an empty list. The engineer checks the API documentation and finds that the endpoint supports pagination with the 'offset' and 'limit' parameters. The current script does not handle pagination. What should the engineer do to retrieve all devices?

Correct answer & explanation
Write a loop that increments the 'offset' parameter by the 'limit' value until all pages are retrieved.
The correct answer implements a loop that increments the offset parameter until all pages are retrieved. Option A is incorrect because increasing the limit may exceed the maximum allowed value. Option B is incorrect because the API does not return a 'next' link in this scenario. Option D is incorrect because using a different library does not solve the pagination issue.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Trap categories for this question
Scenario analysis trap
Incorrect because the scenario states the API does not provide a 'next' link; it uses offset and limit parameters.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
