350-401 Question #570: Real Exam Question with Answer & Explanation

Question

Based on the router's API output in JSON format below, which Python code will display the value of the "hostname" key?

Options

• Ajson_data = response,json()
• Bjson_data = json.loads(response.text)
• Cjson_data = json.loads(response.text)
• Djson_data = response.json()

Explanation

Explanation

Option A (json_data = response.json()) is correct because the response.json() method is a built-in Requests library function that automatically parses the JSON response from an API call into a Python dictionary, allowing you to then access values like json_data["hostname"] directly. Note that the answer key shows a comma in option A (response,json()), which appears to be a typo in the question - the intended correct syntax uses a dot (response.json()), making it functionally identical to option D.

Options B and C (json.loads(response.text)) are technically valid Python for parsing JSON but require importing the json module separately and manually extracting the response text first - they are the "longer way" to achieve the same result. Option D (response.json()) is actually syntactically identical to the intended answer A, suggesting a formatting error in the question itself.

Memory Tip: Think of response.json() as the "shortcut" method - when using the Requests library, the response object already has a built-in .json() method, so you don't need to import anything extra. If you see response.json() versus json.loads(response.text), always prefer the cleaner dot-method notation for Requests-based API calls on the exam.
