Nutanix NCP-CN Practice Test Questions Answers

The NKPA course specifies the supported operating systems for NKP clusters deployed using the Nutanix provisioning method (CAPX), which leverages Cluster API for Nutanix (CAPX) to provision clusters on Nutanix AHV. The supported OS platforms for CAPX areRocky LinuxandUbuntu, as these distributions are tested and optimized for Nutanix infrastructure and Kubernetes requirements.

Rocky Linux is a CentOS replacement adopted by Nutanix after CentOS 8’s end-of-life in 2021, providing a stable, enterprise-grade OS. Ubuntu, particularly LTS versions like 20.04 or 22.04, is widely supported due to its compatibility with Kubernetes and Nutanix AHV. The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “When deploying NKP with the Nutanix provisioning method (CAPX), the supported OS platforms are Rocky Linux and Ubuntu, ensuring compatibility with Nutanix AHV and Kubernetes.” These OS images are typically prepared using NKP Image Builder (NIB) to include necessary components like kubeadm and containerd.

Incorrect Options:

A. CentOS and Rocky Linux: CentOS 8 is no longer supported post-2021, and Nutanix has shifted to Rocky Linux.

C. Flatcar, Rocky Linux, and Ubuntu: Flatcar Container Linux is not a supported OS for CAPX in NKP deployments.

D. CentOS and Ubuntu: CentOS is not supported, as noted above.

TheKonvoy Image Builderrequires a64-bit Linux or MacOS environment(x86_64 architecture) to build and customize the OS images.

According to theNKPA 6.10 documentation, the critical system components for NKP nodes are:

kubelet

containerdThese components are deployed in the standard Linux path:/var/lib.

Exact extract from the documentation:

“The kubelet and containerd services require disk space in /var/lib on the host operating system. It’s essential to allocate sufficient storage in /var/lib to accommodate these core Kubernetes components.”

According to theNKPA 6.10 documentation, thePre-provisioned infrastructure provider (CAPPP)requires the user to provide aninventory fileof the servers that will become the cluster nodes. This inventory file contains connection information (IP addresses, credentials, etc.) for each pre-provisioned node, enabling the Cluster API to connect and configure these servers directly during cluster creation.

The NKPA course outlines the specifics of integrating Azure Kubernetes Service (AKS) with NKP, focusing on fleet management and the deployment architecture. The correct statements are:

Existing AKS clusters must be attached to the Management cluster (Option A):NKP does not provision AKS clusters directly because AKS is a managed Kubernetes service. Instead, NKP attaches existing AKS clusters to its management plane for centralized management. The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “For AKS integration, existing AKS clusters must be attached to the NKP Management cluster using the Attach Cluster functionality, as NKP does not provision AKS clusters.” This involves creating a service account with cluster-admin permissions in the AKS cluster and providing its kubeconfig to NKP.

NKP Management cluster with the Kommander component must be installed before installing NKP on AKS cluster (Option C):The Kommander component is part of the NKP Management cluster and provides the centralized management plane for fleet management, including AKS clusters. The NKPA course specifies that an NKP Management cluster with Kommander must be deployed before attaching or managing external clusters like AKS. The NCP-CN 6.10 Study Guide notes: “An NKP Management cluster with Kommander must be installed prior to integrating AKS clusters, as Kommander enables the fleet management capabilities for external clusters.”

Incorrect Options:

B. AKS best practices encourage building customized images: AKS best practices recommend using the default node images provided by Azure, which are optimized for AKS features like autoscaling and security. Custom images can lead to loss of functionality, as noted in previous questions (e.g., Q91).

D. AKS clusters can be deployed as Management or Pro NKP clusters: AKS clusters are attached, not deployed, by NKP. Additionally, AKS clusters cannot serve as NKP Management clusters; the Management cluster must be deployed on supported infrastructure like Nutanix AHV, AWS, or vSphere. “Pro NKP clusters” is not a valid term in NKP documentation—Pro refers to a license tier, not a cluster type.
