Refer to the exhibit. This exhibit is a simple Python script to monitor call activity for a local Webex room device. Which code snippet listens for call events and completes the script?

Question

Options

• Aawait client.xfeedback(['Feedback', 'Call', 'Status'], callback, False)
• Bawait client.subscribe(['Feedback', 'Call', 'Status'], callback, False)
• Cawait client.subscribe(['Status', 'Call', 'Status'], callback, False)
• Dawait client.xfeedback(['Feedback', 'Call', 'Status'], callback, False)

• A
  3% (1)
• B
  12% (4)
• C
  76% (26)
• D
  9% (3)

Explanation

Option C is correct because Webex xAPI status paths begin with 'Status' - making ['Status', 'Call', 'Status'] the accurate path for call status events - and the correct Python SDK method for subscribing to device feedback is subscribe, not xfeedback. Options A and D both fail on two counts: they use the non-existent xfeedback method name and incorrectly start the path with 'Feedback' instead of 'Status'. Option B uses the correct subscribe method but still has the wrong path prefix ('Feedback'), which would not match any valid xAPI status node.

Memory tip: Use the "3 S's" rule - you always Subscribe to a Status path that Starts with 'Status'.
