PMLE Collaborating to manage data and models Practice Question

Network Topology

Refer to the exhibit. The team wants to automatically deploy the best-performing model version to production. They have set up a Cloud Function triggered by Model Registry events. Which alias should they use in the function to get the latest champion?

⚠ Common exam trap

Google Cloud often tests the distinction between 'champion' (a production alias) and 'latest' (a version number concept), leading candidates to incorrectly choose 'latest' because they confuse chronological recency with performance-based promotion.

Correct answer & explanation

✓

'champion'

The 'champion' alias is specifically reserved in Vertex AI Model Registry to denote the best-performing model version in production. By configuring the Cloud Function to trigger on the assignment of the 'champion' alias, the team ensures that only the model version promoted as the production champion is automatically deployed, aligning with MLOps best practices for staged model promotion.
