Q24 Single choice

You are designing a Google Kubernetes Engine (GKE) cluster for a rapidly scaling microservices application. The application will have thousands of pods and hundreds of services. The application requires internal pod-to-pod communication and exposure of services internally. You want to follow Google's recommended approach to ensure efficient IP address utilization within your existing Virtual Private Cloud (VPC) subnet while leveraging Google Cloud's native networking capabilities.

What should you do?

A
Deploy a route-based GKE cluster and rely on GKE-managed routing tables for all pod and service communication.
B
Allocate a primary IP address range for the entire cluster to encompass both node, pod, and service IP addresses.
C
Configure the GKE cluster to use a VPC-native mode with the main subnets primary IP range for nodes, and separate secondary IP ranges for pods and services.
D
Implement a mesh of Istio service proxies on every pod to manage all internal pod-to-pod communication and service discovery.
