A Platform Engineer is running a Kubernetes cluster version 1.

The NKPA course details the process for upgrading an NKP-managed Kubernetes cluster, such as one running on AWS from version 1.28.1 to 1.29.9. Upgrading a Kubernetes cluster involves two distinct steps: upgrading the control plane nodes and upgrading the worker nodes, ensuring minimal disruption and maintaining compatibility. The NKP CLI provides specific commands to handle these upgrades separately for AWS clusters.

Upgrade Control Planes with nkp update controlplane aws --cluster-name=${CLUSTER_NAME} --ami AMI_ID --kubernetes-version=v1.29.9 (Option B):The control plane must be upgraded first to the target Kubernetes version (1.29.9). The nkp update controlplane aws command updates the control plane nodes, specifying the cluster name, the new Kubernetes version, and an updated AMI (Amazon Machine Image) that supports the target version. The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “To upgrade an NKP cluster on AWS, first update the control plane using nkp update controlplane aws --cluster-name --ami --kubernetes-version to ensure the control plane runs the desired Kubernetes version.” The --ami flag is required to specify a compatible image for the upgraded control plane nodes.

Upgrade Workers with nkp upgrade nodepool aws ${NODEPOOL_NAME} --cluster-name=${CLUSTER_NAME} --kubernetes-version=v1.29.9 (Option C):After the control plane is upgraded, the worker nodes in each node pool must be upgraded to match the control plane version. The nkp upgrade nodepool aws command updates the specified node pool to the target Kubernetes version (1.29.9). The NKPA course notes: “Upgrade worker nodes using nkp upgrade nodepool aws --cluster-name --kubernetes-version , which performs a rolling update to ensure minimal downtime.” This command automatically handles the rolling update of worker nodes, replacing them with new nodes running the updated version. Note that the --ami flag is not required here, as NKP typically uses the same AMI as the control plane or retrieves a compatible one based on the version.

Incorrect Options:

A. nkp update nodepool aws: The correct command is nkp upgrade nodepool, not nkp update nodepool. The NKPA course uses upgrade for version changes to node pools.

D. nkp update cluster aws: This command is not the standard approach for upgrading Kubernetes versions in NKP. The course specifies separate commands for control plane and node pool upgrades to ensure a controlled process.
