NCP-CN Practice Questions

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.

The NKPA course details that backup and restore functionality in NKP is provided through integration with Velero, which supports backing up persistent volumes, cluster resources, and application data to S3-compatible storage. This functionality is considered an advanced feature and is included in higher-tier NKP licenses: NKP Ultimate and NKP Pro.

NKP Ultimate: This top-tier license includes all NKP features, such as air-gapped deployments, fleet management, and backup/restore capabilities. It is designed for enterprise-grade environments requiring comprehensive disaster recovery.

NKP Pro: This mid-tier license also includes backup and restore functionality, catering to organizations needing robust data protection but not necessarily all the features of the Ultimate tier (e.g., air-gapped support).

The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “Backup and restore functionality, powered by Velero, is available in NKP Pro and NKP Ultimate license tiers, enabling protection of persistent volumes and cluster resources.” These licenses provide the necessary tools and support for configuring Velero with S3-compatible storage, scheduling backups, and performing restores in production environments.

Incorrect Options:

A.  

NKP Starter: The Starter tier is entry-level and does not include advanced features like backup and restore. It focuses on basic cluster management.

B.  

NKP Essential: This tier, if it exists in NKP’s licensing model, would be a lower tier and unlikely to include backup/restore functionality, as it is not mentioned in the NKPA course.

Comprehensive and Detailed Explanation:

Both the Konvoy Image Builder (KIB) and the Nutanix Image Builder (NIB) are included tools used to create and manage custom OS images suitable for NKP deployments. KIB is responsible for building images that conform to the standards required by Konvoy-based environments, while NIB is designed for direct integration with the Nutanix AHV infrastructure. These tools support automated preparation, hardening, and upload of images to the appropriate repositories.
