I am following the article mentioned below for creating dynamic persistent volume claims.

https://docs.microsoft.com/en-us/azure/aks/azure-disks-dynamic-pv

I created a Persistent volume claim using :

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: taskmanager-01
spec:
  accessModes:
  - ReadWriteOnce
  storageClassName: managed-premium
  resources:
    requests:
      storage: 16Gi

Question 01 :

From what I understand, the Persistent Volume and the actual underlying disk will be provisioned when this is created.

Is this correct ?

Question 02 :

kubectl get pvc -n <namespace>

returns me the status of my PVC as Pending. I get the following errors in the kubernetes event list

Failed to provision volume with StorageClass "managed-premium":
