Options

Correct Answer:

Explanation

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.

Why Incorrect

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.

References

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.

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").
