{‘lat’: 37.4180951010362, ‘lng’: -122.098531723022, ‘address’: ”, ‘serial’: ‘Q2HP-F5K5-F98Q’, ‘mac’: ’88:15:44:ea:f5:bf’, ‘lanIp’: ‘10.10.10.15’,
‘url’: ‘https://n149.meraki.com/DevNet-Sandbox/n/EFZDavc/manage/nodes/new_list/78214561218351′, ‘model’: ‘MS220-8P’, ‘switchProfileId’: None, ‘firmware’: ‘switch-11-31’, ‘floorPlanId’: None}
What Python code is needed to retrieve the longitude and latitude coordinates of the device?
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]
Answer: B
Explanation:
The ‘text’ property of a Response object returs the dictionary as a string, but it is NOT the dictionary itself.
>>> import requests
>>> publicapi = requests.get(url=”https://api.publicapis.org/entries”)
>>> publicapi.text
‘{“count”:1418,”entries”:[{“API”:”AdoptAPet”,”Description”:”Resource to help get pets adopted”,”Auth”:”apiKey” (…) ‘
>>> type(publicapi.text)
< class ‘str’>
>>> type(publicapi.json())
< class ‘dict’>

Drag and Drop Question
A developer is creating a Python script to catch errors using REST API calls and to aid in debugging. Drag and drop the code from the bottom onto the box where the code is missing to implement control flow for REST API errors. Not all options are used.
Answer:
Explanation:
In the event of a network problem (e.g. DNS failure, refused connection, etc), Requests will raise a ConnectionError exception.
In the event of the rare invalid HTTP response, Requests will raise an HTTPError exception.
If a request times out, a Timeout exception is raised.
If a request exceeds the configured number of maximum redirections, a TooManyRedirects exception is raised.
All exceptions that Requests explicitly raises inherit from requests.exceptions.RequestException.

Once developers have built the docker application, running the standard “docker save” command can be used to export the application as “.tar” compressed file. The application can then be deployed on the Catalyst 9000 series switches. Cisco’s ioxclient tool is no longer required to package the application. Ioxclient is an optional tool for developers who want to define additional parameters for the application.
