NCP-CN Nutanix Certified Professional - Cloud Native v6.10

Attaching an existing Amazon EKS cluster to NKP for fleet management involves integrating the cluster into NKP’s management plane, which requires specific preparatory steps. The NKPA course outlines that the first step is to create a service account with cluster-admin permissions in the EKS cluster. This service account is used by NKP to authenticate and manage the cluster, enabling operations like monitoring, scaling, and application deployment.

The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide explains: “To attach an external Kubernetes cluster, such as Amazon EKS, to NKP, a service account with cluster-admin role bindings must be created to allow NKP to interact with the cluster’s API server.” The service account is configured with a token that NKP uses to authenticate requests. The NKPA course provides detailed steps, including creating the service account, assigning the cluster-admin ClusterRole, and generating a token for NKP integration. This step is critical to ensure NKP has the necessary permissions to manage the EKS cluster.

Incorrect Options :

A. Configure a ConfigMap according to EKS configuration : While ConfigMaps may be used for specific configurations, they are not the first step for attaching an EKS cluster. The NKPA course prioritizes service account creation.

C. Configure HAProxy to get connected to EKS clusters : HAProxy is a load balancer, not required for attaching EKS clusters to NKP. EKS uses AWS-native load balancers, and NKP connects via the Kubernetes API.

D. Deploy cert-manager in the EKS clusters : Cert-manager is used for certificate management, not a prerequisite for attaching EKS clusters. The NKPA course does not list it as a required step.

As per the NKPA 6.10 documentation , the primary requirement for attaching external (self-managed) Kubernetes clusters to NKP is network connectivity . Specifically, the NKP management cluster must be able to communicate with the Kubernetes API server and relevant services of the target cluster. This allows NKP to collect metrics, perform health checks, and manage the attached cluster through Kommander and associated tools.

Exact extract:

“For attaching existing Kubernetes clusters, ensure the NKP management cluster can reach the Kubernetes API server of the target cluster and that the kubeconfig used has sufficient permissions.”

There is no requirement that the Kubernetes versions be exactly matched or within N-1, nor that an NKP admin account be directly established on the target clusters; the connectivity and valid kubeconfig file are the essential requirements.
