Microsoft Azure Administrator Associate AZ-104 Practice Question
You are an administrator for an Azure Kubernetes Service (AKS) cluster and need to perform a manual upgrade to a newer supported Kubernetes version. What is the correct sequence of operations for this upgrade?
The control plane and all associated node pools must always be upgraded simultaneously.
You must first delete all existing node pools, upgrade the control plane, and then create new node pools with the new version.
First, upgrade all associated node pools, and then upgrade the cluster's control plane.
First, upgrade the cluster's control plane, and then upgrade the associated node pools.
When upgrading an Azure Kubernetes Service (AKS) cluster, the control plane must be upgraded before the node pools. After the control plane upgrade is complete, the node pools can be upgraded to the same Kubernetes version. The az aks upgrade command can be used with the --control-plane-only flag to upgrade just the control plane, followed by a separate az aks nodepool upgrade command for the node pools. Alternatively, running az aks upgrade without flags upgrades the control plane and then all node pools together.
