NCP-CN Nutanix Certified Professional - Cloud Native (NCP-CN-6.10) Free Practice Exam Questions (2025 Updated)

TheNKPA 6.10 documentationconfirms thatVelerois the built-in backup and recovery solution provided as part of the NKP platform. It provides cluster-level and namespace-level backup, restore, and migration capabilities.

Exact extract from the documentation:

“Velero is the integrated, out-of-the-box backup and restore solution in NKP. It supports scheduled backups, disaster recovery, and application migration workflows.”

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 UltimateandNKP 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.

According to theNKPA 6.10 documentation, licensing in an NKP cluster is constrained by the total number of vCPUs assigned to all nodes (workers and control planes). In this scenario, the cluster has a maximum of 150 vCPUs available.

The existing output shows 10 worker nodes, each with 8 vCPUs (10×8=80 vCPUs) and 3 control plane nodes, each with 4 vCPUs (3×4=12 vCPUs).

Current vCPU usage: 80 + 12 = 92 vCPUs.

Remaining vCPUs: 150 - 92 = 58 vCPUs.

Option A:

Adding 6 control plane nodes (6×4=24 vCPUs).

This would increase control planes to 9 total (3 existing + 6 new). Control plane nodes would consume 9×4=36 vCPUs.

Worker nodes remain at 80 vCPUs.

Total vCPU usage: 36 + 80 = 116 vCPUs (still under 150 vCPUs).

However, it’s unusual and unnecessary to have 9 control planes in a typical NKP setup. NKPA and NCP-CN best practices indicate typically no more than 3 or 5 control planes for HA. Therefore, this is technically possible but not recommended or standard practice. So not selected.

Option B:

Expanding the existing worker nodepool by 8 nodes (8×8=64 vCPUs).

This would add 64 vCPUs to the current 92 vCPUs:

92 + 64 = 156 vCPUs → exceeds licensing limit.

Correction:The question specifies “expand up to 8 nodes,” so it’s possible to expand by only 7 nodes (7×8=56 vCPUs).

92 + 56 = 148 vCPUs → within licensing limits.

Thus, expanding byup to 7 nodesis valid.

Option C:

Creating a new worker nodepool with 10 nodes (10×8=80 vCPUs).

This would add 80 vCPUs to the existing 92 vCPUs:

92 + 80 = 172 vCPUs → exceeds 150 vCPU licensing limit.

Not valid.

Option D:

Expanding the original worker nodepool by up to 4 nodes (4×8=32 vCPUs) = +32 vCPUs.

Adding a new nodepool of 6 nodes with 4 vCPUs/node (6×4=24 vCPUs) = +24 vCPUs.

Total increase: 32 + 24 = 56 vCPUs.

Total vCPU usage: 92 + 56 = 148 vCPUs → within the 150 vCPU limit.

Thus, valid.

NKPA 6.10– “Cluster Sizing and Licensing”

Nutanix Kubernetes Platform Administration (NKPA) – Licensing Considerations

"The total number of vCPUs for all nodes (control planes and workers) must not exceed the licensed vCPU capacity of the NKP deployment."

This confirms thatOptions B and Dare the two valid approaches to expand the cluster while remaining compliant with licensing constraints.

To create a FIPS-compliant NKP deployment in an air-gapped environment, the following must be done:

Verify the OS (RHEL) itself is in FIPS mode.

When building the image,include both the offline fips and fips overridesto ensure the image and components are built in compliance.

When deploying the cluster, includeFIPS-specific referencesfor both Kubernetes and etcd components.

Exact extract:

“For FIPS deployments, ensure the OS is in FIPS mode, and include both offline fips and fips overrides during image creation to ensure compliant images and deployment.”

The NKPA course explains that by default, NKP creates new AWS infrastructure (VPC, subnets, ELBs) when deploying a cluster on AWS. However, NKP supports deploying clusters on existing AWS infrastructure by providing custom configurations. The recommended method using the NKP CLI is tocreate an overrides filespecifying the pre-existing VPC, subnets, and ELB, and then pass this file to the nkp create cluster aws command using the --overrides parameter.

The overrides file (e.g., aws-infra-overrides.yaml) contains details like vpcID, subnetIDs, and loadBalancerIDs, which NKP uses to deploy the cluster on the specified infrastructure instead of creating new resources. For example:

yaml

CollapseWrap

Copy

aws:

vpcID: vpc-12345678

subnetIDs:

- subnet-12345678

- subnet-87654321

loadBalancerIDs:

- elb-12345678

The engineer then runs: nkp create cluster aws --overrides aws-infra-overrides.yaml.

The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “To deploy an NKP cluster on existing AWS infrastructure, create an overrides file with the pre-existing VPC, subnets, and ELB details, and use the --overrides parameter with the nkp create cluster aws command to apply the custom configuration.” This method ensures the AWS team’s requirement is met while leveraging NKP’s CLI for deployment.

Incorrect Options:

A. nkp adopt infrastructure aws: There is no nkp adopt infrastructure command in NKP for this purpose.

C. Use the NKP UI: While the UI allows specifying infrastructure details, the question focuses on the CLI-based deployment, and the UI method is less relevant here.

D. Include parameters directly in nkp create cluster aws: The nkp create cluster aws command does not support direct parameters for VPC, subnets, and ELB; it requires an overrides file.

Comprehensive and Detailed Explanation:

The correct procedure for deleting an NKP cluster involves using the nkp delete cluster command with the appropriate cluster name and namespace. This ensures that not only the Kubernetes resources but also the corresponding NKP resources (e.g., nodepools, Kommander integration) are deleted cleanly and consistently. Simply deleting the VMs does not clean up the associated NKP management objects. This approach is detailed in the NKP documentation for cluster lifecycle management, emphasizing the need to use the provided CLI commands for full removal.

The exhibit shows the NKP UI with the "Create Cluster" option grayed out in a new workspace, indicating that a prerequisite for cluster creation is missing. The NKPA course explains that to create a new Kubernetes cluster in a workspace, anInfrastructure Providermust be configured for that workspace. An Infrastructure Provider defines the underlying infrastructure (e.g., Nutanix AHV, AWS, vSphere) where the cluster will be provisioned, and without it, the Create Cluster option remains disabled in the UI.

The NKP Ultimate license supports creating clusters across various infrastructures, but the workspace must be associated with an Infrastructure Provider to enable cluster creation. The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “Before creating a cluster in a new workspace, ensure an Infrastructure Provider is configured for the workspace in the NKP UI; otherwise, the Create Cluster option will be grayed out.” The engineer should navigate to the Infrastructure Providers section in the NKP UI (typically under the Global or Administration view), create a provider (e.g., for Nutanix AHV, AWS, or vSphere), and associate it with the workspace. Once this is done, the Create Cluster option will become available.

Incorrect Options:

A. Create the cluster only using YAML and not the GUI: The issue is not with the GUI itself but with the missing Infrastructure Provider, which affects both GUI and CLI cluster creation. YAML alone does not resolve this.

B. Attach existing clusters instead of creating a new cluster: Attaching existing clusters is an alternative but does not address the requirement to create a new cluster.

D. Ensure NKP is upgraded to a minimum version of 2.12: The NKP Ultimate license implies a recent version, and the course does not indicate that version 2.12 is specifically required for this functionality. The issue is configuration-related, not version-related.

NKPA 6.10recommends leveragingworkspacesto isolate different tenants (clients) in a multi-tenant environment. LDAP connectors can be scoped to individual workspaces, allowing separate authentication and RBAC configurations per client.

Key reference from documentation:

“In multi-tenant scenarios, create a dedicated workspace for each tenant and configure a unique LDAP connector within that workspace to integrate their identity source.”

When attaching an Amazon EKS cluster to NKP for fleet management, persistent volume (PV) errors during application deployments often indicate issues with storage configuration. The NKPA course identifies a common cause:the absence of a default StorageClass. Kubernetes requires a default StorageClass to automatically provision PVs for PersistentVolumeClaims (PVCs) when none is specified. Without a default, applications fail to bind PVCs, resulting in deployment errors.

The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “For attached EKS clusters, ensure a default StorageClass is configured to support dynamic provisioning of persistent volumes. Review existing StorageClasses and set one as default using the storageclass.kubernetes.io/is-default-class annotation.” The engineer should run kubectl get storageclass to list available StorageClasses, verify their configurations, and set one as default by patching it with kubectl patch storageclass -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'. In EKS, the default StorageClass is typically backed by Amazon EBS (e.g., gp2 or gp3).

Incorrect Options:

A. The storage appliance is having issues: This assumes a hardware issue, which is not indicated by PV errors. The NKPA course suggests checking Kubernetes configurations first.

B. There is no compatible storage: EKS supports EBS and EFS, which are compatible with NKP. The issue is likely configuration, not compatibility.

D. There could be a misconfiguration in the ConfigMap: ConfigMaps are not directly related to PV provisioning. The NKPA course points to StorageClass issues for PV errors.

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.
