Exam Professional Cloud Developer topic 1 question 40 discussion

B is the best option here. You can refer to : https://cloud.google.com/kubernetes-engine/docs/concepts/statefulset

A StatefulSet is the Kubernetes object best suited for workloads where each pod needs a stable network identity and its own persistent disk.

The correct answer is B. StatefulSet. StatefulSets are used to manage the deployment and scaling of stateful applications. They provide a stable network identity and persistent storage for each instance of the application. They are designed to work with applications that require a stable network identity and persistent storage, such as databases, message brokers, and other stateful applications. In contrast, Deployments are used to manage the deployment and scaling of stateless applications, which do not require a stable network identity or persistent storage. ReplicaSets and ReplicaControllers are similar to Deployments, but are older and less commonly used in GKE.

B is correct

Once created, the StatefulSet ensures that the desired number of Pods are running and available at all times. The StatefulSet automatically replaces Pods that fail or are evicted from their nodes, and automatically associates new Pods with the storage resources, resource requests and limits, and other configurations defined in the StatefulSet's Pod specification

B is ok

B its OK

C doesn't provide a stable network identity and its own persistent disk

For me C is correct answer
