Exam 350-901 topic 1 question 114 discussion

The question is testing the understanding of the use of requests and the passing of form and json data to the requests module. In all options the headers are indicating that the accepted format is json data. The data variable is a python dict and if passed to data is treated as a form encoded data. to pass the contents of the dict as json you need to use json.dumps(data). More detail from reading the requests module documentation with similar example. https://docs.python-requests.org/en/master/user/quickstart/#more-complicated-post-requests.

D is the correct answer. Very good example on the following link: https://github.com/CiscoDevNet/fmc-rest-api/blob/master/labs/firepower-restapi-106/4.md

B, in A headers=headers is missing, and rise.for.status

D is correct! B and D looks the same... but type is different so why json.dumps should be used. import json data={"param_1":"value_1","param_2":"value_2"} print(data,type(data)) print(json.dumps(data),type(json.dumps(data))) {'param_1': 'value_1', 'param_2': 'value_2'} <class 'dict'> {"param_1": "value_1", "param_2": "value_2"} <class 'str'>

D is correct. With Content-Type: Application/json, you have two choices to insert data in the request: data = json.dump(data) >> the data in parenthesis is the name of the dictionary variable or json = data >> again, data is the name of our dictionary

B and D are correct

I'd go with D, as it is more correct. The server may understand form-encoded data (in the case of B), but it isn't guaranteed. https://stackoverflow.com/questions/47188244/python-requests-library-data-vs-json-named-arguments-with-requests-post

If you think about it, but Headers and Data are Json information. Because in both options, Header is pointing to the variable, I would expect to handle the same with the Data variable. That plus SSSSSS confirmed it works without the dump option.

This is a terrible question. Both B and D are correct. This question probably dates back from when you had to use json.dumps() on a dict containing your POST data. This is not necessary for a considerable time already. So I'm hoping this question does not come in my test, of at least that it has been updated recently, because as of today it is simply broken.

D is correct. See section "Function create one host object" https://cyruslab.net/2020/02/27/pythoncisco-fmc-rest-api-example-get-server-version-and-add-device-to-cisco-fmc/

B is the correct answer.

The answer is D... json.dumps it's very important to send the message... The data you create on python it's on dictionary structure use for Python.. when you send to an API and you confirm in your header Json structure, you need to parse it to Json.

A is wrong due to missing headers argument C is wrong due to swapped data and headers variables B or D could be right. All 4 options don't define error. I'm assuming the test with have 'except Exception as error:' before print(error) vs 'except:'
