NCP-CN Exam Dumps - Nutanix Certified Professional (NCP) Questions and Answers

The Nutanix Kubernetes Platform (NKP) uses the Kubernetes Image Builder (KIB) or Nutanix Image Builder (NIB) to create custom machine images for NKP management and worker nodes. These images are tailored to include specific versions of Kubernetes, container runtimes (e.g., containerd), and other dependencies. The NKPA course specifies that KIB relies on Ansible playbooks to configure the image, and the versions of packages like Kubernetes and containerd are defined in Ansible configuration files.

The correct location to verify the package versions isansible/group_vars/all/defaults.yaml. This file contains the default variables used by Ansible during the image-building process, including the versions of Kubernetes and containerd. For example, it may include entries like kubernetes_version: 1.30.5 and containerd_version: 1.7.22. The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “To ensure the correct versions of Kubernetes and containerd are used in KIB, check the ansible/group_vars/all/defaults.yaml file, which specifies the package versions for the image build.” The engineer can review and modify this file to confirm that the security team’s authorized versions (Kubernetes 1.30.5 and containerd 1.7.22) are being used.

Incorrect Options:

A. config/pulumi/vars/pulumi.kib.config: Pulumi is an infrastructure-as-code tool, but it is not used by KIB for specifying package versions. The NKPA course does not reference this file.

B. terraform/vars/default/terraform.tfvars: Terraform is used for infrastructure provisioning, not for defining software versions in KIB images.

D. The custom image's .env file: KIB does not use a .env file for version configuration; Ansible variables are used instead.

The NKPA course highlights thatNKP Insightsis the platform’s integrated solution for observability and analytics, providing predictive analytics to detect current and future anomalies in Kubernetes clusters. NKP Insights leverages machine learning to analyze metrics, logs, and events, identifying performance issues and potential failures proactively. After deploying a new cluster, the administrator can enable NKP Insights as a platform application in the workspace to meet the predictive analytics requirement.

The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “NKP Insights provides predictive analytics and anomaly detection for Kubernetes clusters, enabling administrators to monitor and optimize cluster performance.” This is deployed via the NKP UI or CLI by enabling the Insights application in the workspace.

Incorrect Options:

B. NCM Intelligent Ops: Nutanix Cloud Manager (NCM) Intelligent Ops is for broader infrastructure management, not Kubernetes-specific analytics.

C. Nutanix Pulse: Pulse is a telemetry service for Nutanix support, not for analytics.

D. NKP AI Navigator: This is not a recognized NKP component in the NKPA documentation.

As per theNKPA 6.10 documentation, the correct approach for deleting an entire NKP-managed cluster (including nodes and deployed applications) is to use the nkp delete cluster command with the cluster name and --kubeconfig parameter. The --self-managed flag ensures the deletion of resources provisioned by the cluster.

Exact extract:

“Use nkp delete cluster --cluster-name= --self-managed --kubeconfig= to delete a cluster and its associated resources.”

For creating custom images for vSphere (and other supported platforms),Konvoy Image Builder(KIB) is the officially supported tool for NKP. It can create images with custom configurations, package versions, and pre-bundled artifacts.

Key Reference:

“Konvoy Image Builder (KIB) is the Nutanix-recommended tool for building NKP cluster node images for vSphere, AWS, Azure, and other environments.”

As per theNKPA 6.10 documentation, the standard and supported approach for installing Kommander on an NKP cluster is using theNKP CLI. The CLI provides commands for deploying Kommander and associated platform components as part of the cluster lifecycle management workflow.

Key Reference:

“The recommended approach to deploy Kommander is by using the nkp CLI, which ensures compatibility and streamlined installation with the rest of the Nutanix Kubernetes Platform stack.”

The scenario describes an isolated environment in Antarctica, implying an air-gapped NKP deployment where the bastion host serves as the primary management point for deploying and managing NKP clusters without Internet access. The NKPA course outlines the essential tools that must be installed on a bastion host to facilitate NKP deployment and management in such environments.

The required programs arekubectlandnkp:

kubectl: This is the Kubernetes command-line tool used to interact with Kubernetes clusters, essential for managing cluster resources, debugging, and applying configurations during and after deployment.

nkp: The NKP CLI (nkp) is the primary tool for deploying, managing, and scaling NKP clusters, including creating bootstrap clusters, deploying clusters, and managing platform applications. In an air-gapped setup, the nkp CLI is critical for executing deployment commands using the Air-Gapped Bundle.

The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “For an air-gapped NKP deployment, ensure the bastion host has kubectl and the nkp CLI installed to manage the deployment process and interact with the resulting Kubernetes clusters.” These tools are sufficient for the engineer to deploy and operate NKP in an isolated environment.

Incorrect Options:

A. awscli and nkp: The awscli is specific to AWS environments, but the question does not specify AWS infrastructure. Additionally, in an isolated environment, awscli is less relevant without Internet access.

B. oc and kubectl: oc is the OpenShift CLI, not used for NKP deployments. NKP uses nkp CLI instead.

C. oc and az: az is the Azure CLI, and oc is for OpenShift—neither is relevant to NKP deployment.

For deployments in air-gapped environments where there is no external Internet connectivity, the --airgapped parameter is required. This instructs the NKP deployment to rely solely on internal resources, using pre-staged images and local container registries, ensuring that no external network dependencies cause deployment failures.

The NKPA 6.10 documentation confirms that the proper method to customize application deployment (including disabling Velero) is by generating a configuration file using thenkp install kommander --initcommand. The file can then be modified to set custom specs and disable Velero, and finally deployed using the nkp install kommander command.

Exact extract:

“Generate a custom configuration file using --init, modify it for your specific environment (including disabling Velero), and deploy with the same nkp install kommander command.”

As per theNKPA 6.10 documentationand cluster autoscaler behavior, when nodes are scaled down in NKP (or any CAPI-managed environment), the node isdeletedfrom the infrastructure provider (vSphere, AWS, Nutanix, etc.). This effectively removes it from both the cluster and the underlying hypervisor or cloud provider, thus freeing up resources and reducing costs.

As per theNKPA 6.10 documentation, the primary requirement for attaching external (self-managed) Kubernetes clusters to NKP isnetwork connectivity. Specifically, theNKP management cluster must be able to communicate with the Kubernetes API serverand 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.
