Developing Applications Using Cisco Core Platforms and APIs (DEVCOR) — Question 156

{'lat': 37.4180951010362, 'lng': -122.098531723022, 'address': '', 'serial': 'Q2HP-F5K5-F98Q',

Refer to the exhibit. A developer needs to find the geographical coordinates of a device on the network L_397561557481105433 using a Python script to query the Meraki API. After running response = requests.get() against the Meraki API, the value of response.text is shown in the exhibit.
What Python code is needed to retrieve the longitude and latitude coordinates of the device?

Answer options

• A. latitude = response.text['lat'] longitude = response.text['lng']
• B. latitude = response.json()['lat'] longitude = response.json()['lng']
• C. latitude = response.json()[0] longitude = response.json()[1]
• D. latitude = response.text[0] longitude = response.text[1]

Correct answer: B

Explanation

The correct answer is B because response.json() parses the JSON response into a Python dictionary, allowing for easy access to the 'lat' and 'lng' values. Option A incorrectly uses response.text, which returns a string, not a dictionary, while C and D incorrectly access the coordinates as list indices or string positions, which would not work with the JSON response structure.
