The answer is that the code should use `requests.put` instead of `requests.post`. The Cisco DNA Center API for assigning a device to a site follows RESTful conventions where the PUT method is used to update an existing resource—in this case, associating a device with a specific site—while POST is reserved for creating new resources. Using POST here will likely trigger a 405 Method Not Allowed error, as the endpoint expects an idempotent update operation. On the ENCOR 350-401 exam, this tests your understanding of REST API methods in the context of network automation with Python scripts, a common topic in the Automation and Programmability section. A frequent trap is assuming all data-sending operations use POST, but remember that assignments and updates typically require PUT. Memory tip: think "PUT in place" for assigning a device to a site—you are putting the device into its designated location, not creating a new device.
350-401 Cisco DNA Center Practice Question
This 350-401 practice question tests your understanding of cisco dna center. 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 writing a Python script to use the Cisco DNA Center API to assign a device to a site. The code snippet is:
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The HTTP method should be PUT instead of POST for assigning a device to a site.
The API endpoint for assigning a device to a site typically uses a PUT method, not POST. Using POST may result in a 405 Method Not Allowed error or unexpected behavior.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
The HTTP method should be PUT instead of POST for assigning a device to a site.
Why this is correct
Correct. The DNA Center API uses PUT for this operation.

Read the scenario before looking for a memorised answer.
✗
The payload should include 'deviceId' and 'siteId' as a list.
Why it's wrong here
The payload format is correct as a dictionary.
✗
The URL is missing the version number.
Why it's wrong here
The URL includes /v1/ which is correct.
✓
The code should use requests.put instead of requests.post.
Why this is correct
This is the same as option A, but both are correct. However, the question expects one answer. Option A is more specific.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 350-401 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.
