Exam 350-401 topic 1 question 358 discussion

With 's' GET https://DNAC:Port//dna/intent/api/v1/network-devices { "response": { "errorCode": "Bad request", "message": "Invalid input request", "detail": "s is not a valid UUID of device" }, "version": "1.0" } without 's' GET https://DNAC:Port//dna/intent/api/v1/network-device { "response": [ { "type": "Cisco 3504 Wireless LAN Controller", "description": "Cisco Controller Wireless Version:8.5.140.0", "serialNumber": "FOL25040021", ------------ lines omitted ----------------------------------------

It should be D. The JSON payload contains the incorrect UUID. 400 - "The client made a request that the server could not understand (for example, the request syntax is incorrect)." https://developer.cisco.com/docs/dna-center/#!get-module-info-by-id A - 404 - Not found (Wrong URL) B,C - 401 - Not authenticated

Options B and C use the status code '401 unauthorized' with an error msg 'invalid toke' or 'invalid_grant.' Option D is incorrect because get requests don't typically have a body, UUID are indicated in the URL path of the GET request.

A is correct

asking these type of question is not right from the cisco they should give full information or full access

Tricky one: 's' at the end of 'network-device' is incorrect, hence the message text 's is not ...' GET /dna/intent/api/v1/network-device/<device_id> ** note no s **

ChatGPT: It looks like you've provided a JSON-formatted response. Is there something specific you would like to know or discuss about this JSON response? Please provide more context or ask a question, and I'll be happy to assist you. Me: Does that mean the JSON payload contains the incorrect UUID? ChatGPT: Yes, based on the provided JSON payload, it appears that the response is indicating that the input request contains an invalid UUID (Universally Unique Identifier) for a device. The "errorCode" is set to "Bad request," and the "message" provides the description "Invalid input request," with additional details mentioning that the provided UUID "s" is not a valid UUID for a device. This suggests that the UUID "s" is not recognized as a valid identifier for a device in the context of the system or service that generated this response.

at the end of the URl there is "|" if you remove it everything is ok

That's another sneaky question as actually both A & D are correct. It is just a matter of what is the root cause and A is as it triggers D. I mean, using an incorrect URI with 's' causes JSON payload to use the UUID of 's' which is incorrect so we get error 400 insread of error 404.

The HyperText Transfer Protocol (HTTP) 400 Bad Request response status code indicates that the server cannot or will not process the request due to something that is perceived to be a client error (for example, malformed request syntax, invalid request message framing, or deceptive request routing). (Source:https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/400 )

I think answer is D, if URL is incorrect then we should get 404

GET /dna/intent/api/v1/network-device

This is a GET, there is no JSON body

Correct URI: GET /dna/intent/api/v1/network-device GET /dna/intent/api/v1/network-device/<device_id> Source: https://developer.cisco.com/docs/dna-center/#!devices/endpoints-and-methods-used So, A looks correct

As per guide CCNP Enterprise 350-401 ENCOR Cisco Certified Network Professional

A is correct

The final "s" of url "/network-devices" is interpreted as UUID ((should be /network-device/), so the correct answer is A.
