Explanation

This question tests the ability to complete a Python script that interacts with a REST API using the 'requests' library to retrieve and parse JSON data.

Approach. The goal is to correctly complete the Python script to list all devices by making an HTTP GET request, handling authentication, verifying SSL, checking for success, and parsing the JSON response. Here's the correct placement for each blank:

1. Blank 1 (requests.____): The script needs to make an HTTP GET request. The 'requests' library provides the get() method for this purpose.

   • Drag get here: deviceStatsJson = requests.get(str(viptela_url) + ...

2. Blank 2 (verify=____): The verify parameter in requests controls SSL certificate verification and expects a boolean value. To enable verification, True (or true in a context where Python's boolean is expected) is used.

   • Drag true here: ..., auth=(viptela_user, viptela_pass), verify=true)

3. Blank 3 (if deviceStatsJson.____): After making a request, it's good practice to check if the request was successful. The requests.Response object has an ok attribute, which is True for successful (2xx) status codes and False otherwise.

   • Drag ok here: if (deviceStatsJson.ok):

4. Blank 4 (json.loads(deviceStatsJson.____)): To parse the JSON response body, json.loads() expects a string or bytes containing the JSON data. The requests.Response object has a content attribute that returns the response body as bytes (and text for string). Given the available options, content is the correct choice to retrieve the raw response body for parsing.

   • Drag content here: jData = json.loads(deviceStatsJson.content)

Common mistakes.

• common_mistake. Common mistakes include:
• Dragging request for Blank 1: While requests.request is a generic method, requests.get is the specific and most common method for HTTP GET requests, making get more appropriate here.
• Dragging content or exists for Blank 2 (verify=____): The verify parameter expects a boolean. content refers to the response body, and exists is not a valid boolean or keyword for this parameter.
• Dragging true for Blank 3 (if deviceStatsJson.____): true is a boolean value itself, not an attribute of the Response object that indicates success. The correct attribute is ok (e.g., response.ok).
• Dragging exists for Blank 4 (json.loads(deviceStatsJson.____)): exists is not an attribute of the requests.Response object that provides the response body. The body is accessed via attributes like text or content.

Concept tested. The core technical concepts tested are Python programming fundamentals, specifically interacting with REST APIs using the 'requests' library, handling HTTP methods (GET), basic authentication, SSL certificate verification, checking HTTP response status codes, and parsing JSON data from an API response.
