The question was posed to me during an interview for a job.

My question comes from Publishing Messages to the Cloud in portion Working with the Cloud of IOT

Answer 1

The correct answer is (b) Canonical form

For explanation I would say: The topic is passed along as a string; all topics have the canonical form of projects/{project_name}/topic/{topic_name}.
