Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Cloud Deploy with a Service Mesh like Istio
Cloud Deploy supports canary deployments with traffic splitting using Service Mesh (Istio) or other ingresses. Istio itself can also be used directly. Cloud Load Balancing can do traffic splitting but not as part of a deployment pipeline. Cloud Shell is just a terminal. Cloud Deployment Manager is for infrastructure deployment.
