Refer to the exhibit. An engineer must create a network Fabric using the Cisco Catalyst Center (formerly DNA Center) API. Which line of code completes the code snippet? ``python import requests from…
The correct answer is C. sda_fabric_info = {"fabricName": "DNAC_Guide_Fabric"}. To create an SDA Fabric using the Cisco Catalyst Center API, the payload for the POST request must be a JSON object containing a fabricName key with the desired fabric name.
Question
import requests
from requests.auth import HTTPBasicAuth
import urllib3
BASE_URL = 'https://<CIP Address>'
AUTH_URL = '/dna/system/api/v1/auth/token'
USERNAME = '<USERNAME>'

token = response.json()['Token']
headers = {'Content-Type': 'application/json', 'X-Auth-Token': token}
SDA_FABRIC_URL = '/dna/intent/api/v1/business/sda/fabric'
# MISSING LINE HERE
response = requests.post(BASE_URL + SDA_FABRIC_URL, headers=headers, json=sda_fabric_info, verify=False)

Why each option
To create an SDA Fabric using the Cisco Catalyst Center API, the payload for the POST request must be a JSON object containing a `fabricName` key with the desired fabric name.
This choice uses double curly braces for the outer dictionary, which would lead to a syntax error in Python; dictionaries are defined with single curly braces.
This choice provides a list containing a single string, not a dictionary with a key-value pair as required for the API payload.
The line `sda_fabric_info = {{"fabricName": "DNAC_Guide_Fabric"}}` correctly assigns a Python dictionary to the `sda_fabric_info` variable, which will be serialized as a JSON object in the `requests.post` call. The dictionary includes the mandatory `fabricName` key with its corresponding string value, matching the expected payload structure for creating an SDA Fabric via the Cisco Catalyst Center API.
This choice is syntactically identical to option C and would also be correct, but typically only one choice is the intended answer in a multiple-choice question format.
