Google PCA Practice Question: Managing Implementation and Ensuring Solution and Operations Reliability
A company uses GKE with Istio for service mesh. They want to implement a canary deployment for a critical service with fine-grained traffic splitting. Which THREE components should they configure? (Choose three.)
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
✓
Kubernetes Service
Istio uses VirtualService, DestinationRule, and Kubernetes Service to achieve canary deployments. VirtualService defines traffic routing rules, DestinationRule defines subsets (versions), and Kubernetes Service serves as a stable endpoint. Ingress Gateway is for external traffic, not internal. HorizontalPodAutoscaler is for scaling, not routing.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Kubernetes Service
Why this is correct
The Service is the target for the VirtualService, providing a stable DNS name.
- ✓
DestinationRule
Why this is correct
Defines subsets (versions) of the service.
- ✗
Ingress Gateway
Why it's wrong here
Ingress Gateway handles external traffic, not internal canary routing.
- ✗
HorizontalPodAutoscaler
Why it's wrong here
HPA scales pods, does not control traffic routing.
- ✓
VirtualService
Why this is correct
Defines traffic routing rules, including weights for subsets.
