Kommander is the management plane for the Nutanix Kubernetes Platform (NKP). The official and prescribed method for deploying the NKP management cluster, which includes Kommander, is by using the dedicated NKP Command Line Interface (CLI). After setting up a bastion host with the necessary prerequisites, the platform engineer uses commands from the NKP CLI, such as nkp create cluster, to initiate and manage the installation process. This ensures a standardized and supported deployment.

A. AWS CLI: This tool is used for managing Amazon Web Services resources and is not the designated tool for installing the NKP management plane.

B. Terraform: This is an Infrastructure as Code (IaC) tool for provisioning underlying infrastructure, not the specific CLI used to execute the Kommander installation itself.

C. Ansible: This is a configuration management tool. While it can automate setup tasks, it is not the primary command-line tool for deploying NKP.

The most efficient method using Nutanix Kubernetes Platform (NKP) is to leverage its fleet management capabilities. This is achieved by creating a Workspace, which acts as a logical grouping for managing multiple clusters as a single entity. The "Attach Cluster" feature is specifically designed to onboard existing CNCF-conformant Kubernetes clusters, such as the lightweight Kubernetes on the 30 edge devices, into the NKP management plane. Once attached, the administrator can use NKP's centralized tools for consistent application lifecycle management, policy enforcement, and monitoring across the entire fleet from a single interface.

A. Create a GitHub configuration, deploy it to the 30 edge devices, and configure them to use a GitHub account.

This describes a generic GitOps implementation but omits the crucial first step of bringing the clusters under NKP's centralized management. Attaching them to a workspace is required to manage GitOps at scale via NKP.

B. Create a script to automate the deployment to every edge device.

This is a manual, less scalable approach that bypasses the advanced fleet management, governance, and visibility features inherent to the NKP Ultimate license. It introduces maintenance overhead that NKP is designed to eliminate.

C. Ask the developers to delete the lightweight Kubernetes and deploy new Kubernetes clusters with NKP.

This is highly disruptive, time-consuming, and unnecessary. NKP is designed to manage existing third-party clusters, making a "rip and replace" strategy the least efficient option.

1. Nutanix Kubernetes Platform Administration Guide - Attaching a Cluster: "You can attach any CNCF-conformant Kubernetes cluster to NKP for centralized management. After you attach a cluster

you can manage the cluster from the NKP console." This directly supports using the "Attach Cluster" feature for existing clusters.

2. Nutanix Kubernetes Platform Administration Guide - Workspaces: "A Workspace is a logical grouping of one or more Kubernetes clusters... Workspaces enable you to manage multiple clusters as a single entity

providing a single pane of glass for all your Kubernetes needs." This confirms that a Workspace is the correct construct for managing the fleet of 30 devices.

When deploying a Nutanix Kubernetes Platform (NKP) cluster to AWS using the command-line interface, the deployment tool must be aware of the target AWS region. Setting the AWSREGION environment variable (e.g., export AWSREGION=us-east-1) is a standard and required method for configuring the environment for AWS CLI tools and SDKs, which NKP utilizes for the deployment. This ensures all API calls are directed to the correct regional endpoint as specified in the requirements.

A. Use --dry-run parameter: The --dry-run parameter is used to validate a command without executing it. It is a best practice for testing but not a requirement for the actual deployment.

B. Use --ami-format parameter: This is not a valid parameter. To specify a custom Amazon Machine Image (AMI), the --aws-ami-id parameter would be used, not one related to format.

D. Set an export KUBECONFIG: The KUBECONFIG environment variable is used to point kubectl to a configuration file for accessing an existing cluster. It is not a prerequisite for creating a new one.

1. Nutanix Kubernetes Platform Administration Guide v2.6: In the "Creating a Kubernetes Cluster on AWS (CLI)" section

a prerequisite is to "Configure your AWS credentials." This configuration includes specifying the default region. (URL: https://portal.nutanix.com/page/documents/details?targetId=Nutanix-Kubernetes-Platform-Admin-Guide-v26:nke-k8s-cluster-aws-create-cli-c.html)

2. AWS Command Line Interface User Guide: The AWS documentation specifies that the region can be configured using the AWSREGION environment variable. This is a standard method for preparing the environment for any AWS operation. (URL: https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-envvars.html

Section: "Environment variables")

The scenario describes a "noisy neighbor" problem, where one application consumes a disproportionate amount of shared cluster resources, negatively impacting others. In Kubernetes, the standard mechanism to enforce fair resource usage and prevent this issue is by using ResourceQuotas and LimitRanges. ResourceQuotas constrain aggregate resource consumption per namespace, capping the total CPU and memory a team can use. LimitRanges enforce resource requests and limits on individual pods within that namespace, ensuring no single workload can monopolize resources. This directly mitigates the problem described.

B. Setting up Network Policies: Network Policies control network traffic flow between pods. They do not manage or limit the consumption of computational resources like CPU or memory.

C. Configuring RBAC: Role-Based Access Control (RBAC) manages user permissions—what actions a user can perform on cluster objects. It does not control the quantity of resources those objects can consume.

D. Implementing Continuous Deployment (CD): CD is a software development practice for automating deployments. It is a process methodology and has no built-in capability to manage or limit cluster resource allocation.

1. Kubernetes Documentation

"Resource Quotas": "A resource quota

defined by a ResourceQuota object

provides constraints that limit aggregate resource consumption per namespace. It can limit the quantity of objects that can be created in a namespace by type

as well as the total amount of compute resources that may be consumed by resources in that namespace."

URL: https://kubernetes.io/docs/concepts/policy/resource-quotas/

2. Kubernetes Documentation

"Limit Ranges": "A LimitRange is a policy to constrain resource allocations (to Pods or Containers) in a namespace." This works in conjunction with quotas to manage resources at a granular level.

URL: https://kubernetes.io/docs/concepts/policy/limit-range/

3. Nutanix Karbon Documentation

"Creating a Kubernetes Cluster (Karbon UI)": While Karbon simplifies deployment

it operates on standard Kubernetes principles. Resource management is a fundamental Kubernetes concept applied to any Karbon-deployed cluster. The solution lies within Kubernetes constructs

not a Karbon-specific feature distinct from them.

URL: https://portal.nutanix.com/page/documents/details?targetId=Karbon-v28:kar-karbon-cluster-create-ui-t.html (This reference establishes that Karbon deploys standard Kubernetes

to which the above Kubernetes documentation directly applies).

The nkp delete cluster command is used to remove a Nutanix Kubernetes Platform (NKP) cluster. According to the scenario, the cluster to be deleted is named temp-ecommerce, and it is a self-managed "Starter" cluster. The correct syntax requires specifying the cluster's name using the --cluster-name flag. Since it is a self-managed cluster, the --self-managed flag is mandatory. Finally, the --kubeconfig flag must point to the cluster's specific configuration file, which is provided as temp-ecommerce.conf. Option C is the only command that correctly assembles all these required parameters.

A: The --all flag is not a valid parameter for the nkp delete cluster command. Deleting a cluster requires explicitly specifying its name for safety.

B: The command is for deleting a cluster, not an application. Using the --application-name flag is incorrect for this operation; --cluster-name must be used.

D: This option incorrectly uses the application's name (temp-shop) as the cluster's name and references a kubeconfig file that does not match the one provided in the scenario.

Nutanix Kubernetes Platform Administration Guide: The procedure for removing a self-managed cluster is detailed here. The guide specifies the exact command syntax: nkp delete cluster --cluster-name --self-managed --kubeconfig . This directly validates the structure and flags used in the correct answer.

Section: Deleting a Self-Managed NKP Cluster

The error message Error: failed to create cluster: failed to connect to docker daemon: is docker running? explicitly indicates that the nkpctl command-line utility cannot communicate with the Docker service on the local machine where the command is being executed. The Nutanix Kubernetes Platform (NKP) requires a local container runtime, such as Docker, to create a temporary bootstrap cluster during the provisioning process. If this runtime is not installed or is not running, the bootstrap process fails, preventing the creation of the target NKP cluster.

B: The error originates from the nkpctl tool's interaction with the local container runtime, not from an Ansible playbook's syntax or execution.

C: A file permission error on the nkpctl binary would typically result in a "Permission denied" shell error, preventing the program from running at all.

D: Helm charts are used to deploy applications onto an already existing Kubernetes cluster; this error occurs during the cluster creation phase itself.

Nutanix Kubernetes Platform Administration Guide: In the "Setting Up the CLI" section

the guide lists "A Docker-compatible container runtime" as a prerequisite for the machine where you run the nkpctl CLI. It states

"The CLI uses a local container runtime to create a local bootstrap cluster to provision a Kubernetes cluster." This directly supports that a non-running Docker service would cause a creation failure.

To deploy a Nutanix Kubernetes Platform (NKP) cluster on pre-existing AWS infrastructure, the documented and correct method is to create an overrides file. This YAML file specifies the identifiers for the existing VPC, subnets, and other components. The nkp create cluster aws command is then executed with the --overrides parameter pointing to this file. This instructs the NKP deployment process to use the specified infrastructure instead of provisioning new resources, thereby meeting the requirement.

A: The nkp adopt command is used for bringing an existing, externally created Kubernetes cluster under NKP management, not for adopting infrastructure components before creating a new cluster.

C: While the UI may offer some customization, the standard and fully supported method for deploying on existing infrastructure (a "brownfield" deployment) is via the CLI with an overrides file.

D: The nkp create cluster aws command does not accept direct command-line parameters for existing infrastructure like VPC or subnet IDs; this level of customization requires an overrides file.

1. Nutanix Karbon Platform Services Documentation - Deploying a Kubernetes Cluster on an Existing AWS VPC: This official guide explicitly states

"To deploy a Kubernetes cluster on an existing AWS VPC

you must create an overrides file that contains the details of your existing AWS infrastructure. You then reference this overrides file when you run the nkp create cluster aws command." It also provides the exact command syntax: nkp create cluster aws --name --version --overrides .

For a Nutanix Kubernetes Platform (NKP) deployment in a dark site (an environment without internet access), the --airgapped flag is a mandatory attribute in the nkp create cluster command. This flag signals to the installer that it must not attempt to reach public repositories for software components. Instead, it must rely exclusively on the pre-downloaded OS images and the container images available in the specified private registry (--registry-url). While the command correctly provides details for a private registry, it is the --airgapped flag that enables the specific dark site deployment workflow.

B. --insecure: This flag is used to trust a private registry with a self-signed or invalid TLS certificate. It is not the primary flag for enabling a dark site deployment.

C. --registry-url: This attribute is already present in the provided command, specifying the location of the private container registry. Therefore, it is not missing.

D. --registry-username: The command already includes --registry-mirror-username, which is the correct flag for providing credentials to the private registry. It is not a missing attribute.

1. Nutanix Kubernetes Platform Deployment Guide: In the section "Deploying a Kubernetes Cluster in a Dark Site (Air-Gapped)

" the documentation explicitly states: "To deploy a Kubernetes cluster in a dark site

you must include the --airgapped flag in the nkp create cluster command." This confirms it is a required flag for this scenario. (URL: https://portal.nutanix.com/page/documents/details?targetId=Nutanix-Kubernetes-Platform-Deployment-Guide:Nutanix-Kubernetes-Platform-Deployment-Guide - Search for "Deploying a Kubernetes Cluster in a Dark Site").

2. Nutanix Kubernetes Platform Command Reference: The reference for the nkp create cluster command details the --airgapped flag as the method to "Deploy a Kubernetes cluster in an air-gapped environment." It also shows the --registry-url and --registry-mirror-username flags

confirming they are distinct from the --airgapped flag. (URL: https://portal.nutanix.com/page/documents/details?targetId=Nutanix-Kubernetes-Platform-Command-Reference:Nutanix-Kubernetes-Platform-Command-Reference - Search for "nkp create cluster").

The correct procedure to deploy an application from the Nutanix Kubernetes Platform (NKP) catalog to a specific cluster involves navigating to that cluster's management interface. The engineer must first select the cluster (prod-01) and view its details. This action leads to the cluster-specific dashboard, which includes the "Application Dashboard". From this dashboard, the engineer can find and enable (deploy) applications like NKP Insights directly onto the selected cluster. This ensures the operation is performed in the correct context, targeting only the prod-01 cluster as intended.

A: This option is less precise. The "Applications" menu selected directly after "Clusters" typically shows a global view, not the specific application management dashboard for the prod-01 cluster.

B: This path describes managing the global application catalog, not deploying an application to a specific cluster. This action would make an app available but not install it on prod-01.

C: This describes an incorrect and non-existent user interface path for deploying the NKP Insights application. The application is managed under the cluster's Application Dashboard.

The correct method for achieving multi-tenancy and delegating administrative control in Nutanix Kubernetes Platform (NKP) is by using workspaces. A workspace serves as a dedicated, isolated environment for a team or tenant. The proper sequence is to first create a workspace for the R&D team. Then, an infrastructure provider (e.g., a Nutanix cluster) is registered specifically within that workspace. Finally, an R&D group is created, and the 'Workspace Admin' role is assigned to this group within the context of the 'R&D' workspace, granting them full control over the resources and clusters deployed inside it.

B: An NKP connector is used for integrating external services like identity providers or container registries, not for creating isolated tenant environments or assigning infrastructure permissions.

C: This option is incorrect because an infrastructure provider is created at the workspace level, not within a project. Projects exist within a workspace and consume the infrastructure assigned to that workspace.

D: Permissions are assigned to groups within the context of a workspace or project, not directly to an infrastructure provider. This option also incorrectly uses the concept of a connector.

1. Nutanix Cloud Native Administrator Guide - Multi-Tenancy: "Nutanix Cloud Native provides multi-tenancy to enable you to create logically isolated environments called workspaces for different teams or tenants... Each workspace has its own set of users

infrastructure

and projects." This confirms that a workspace is the correct top-level object for isolation.

2. Nutanix Cloud Native Administrator Guide - Onboarding an Infrastructure: The procedure for onboarding an infrastructure provider clearly states that you must first select the workspace into which the infrastructure will be added. "To onboard an infrastructure

you must be a platform administrator or a workspace administrator... In the Workspaces view

select the workspace where you want to onboard the infrastructure." This refutes option C.
