Which Vertex AI feature should an ML Engineer use to run an A/B test between two model versions — splitting traffic between them and comparing metrics?
ACloud DNS
BVertex AI traffic splitting on a single endpoint (multiple model versions with weight-based split)
CManually toggling between models in code each hour
DCloud Memorystore
Answer & Solution
Correct answer: B. Vertex AI traffic splitting on a single endpoint (multiple model versions with weight-based split)
Vertex AI traffic splitting enables A/B (per PMLE §4.1). The other options aren't A/B.
