[Manage Building an NKP Cluster] A company has decided to expand NKP to features that require higher product tiers, like fleet- management and additional infrastructure providers. The company has already obtained the necessary licensing. Which action is required when adding and activating a license from NKP Starter to a higher-tier product?

Upgrading a Nutanix Kubernetes Platform (NKP) license is a privileged administrative action. According to the official Nutanix documentation, only a user assigned the Global License Administrator role has the necessary permissions to add and activate a new license key. If the current user session does not have this role, the user must log out and log back in with an account that possesses these specific privileges to access the license management features in the NKP web console and apply the higher-tier license.

A. Contact Nutanix Support: This is not required for a standard license activation, which is a self-service administrative task.
B. Ensure that worker nodes are sized appropriately: While new features may require more resources, node sizing is a separate infrastructure management task, not a prerequisite for activating the license itself.
D. Regenerate the ACME-based certificate for NKP: Certificate management is related to securing communication and identity, not to feature entitlement through licensing.

Nutanix Kubernetes Platform Administration Guide, "Licensing for Nutanix Kubernetes Platform" section. The documentation states, "To add and activate a license, you must be a Global License Administrator." This confirms the requirement for a specific user role to perform the action.
