In an air-gapped NKP environment with no Internet access, a bastion host is a critical component for secure management. The NKPA course defines the primary purpose of a bastion host asproviding a secure point for creating and operating NKP clusters. The bastion host acts as a jump server, allowing administrators to securely access the isolated environment, manage cluster deployments, and perform operations like cluster creation, scaling, and upgrades without exposing the environment to external threats.

The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “In a dark site NKP deployment, a bastion host serves as a secure entry point for administrators to create, manage, and operate NKP clusters, ensuring isolation from external networks.” The bastion host is configured with SSH keys and tools like the NKP CLI to facilitate secure interactions with the cluster infrastructure.

Incorrect Options:

A. To store and manage sensitive data: The bastion host is not a storage system; its role is access and management, not data storage.

C. To serve as a load balancer: A bastion host does not perform load balancing; that role is handled by Kubernetes components like MetalLB or cloud-native load balancers.

D. To act as a firewall: While a bastion host enhances security, it is not a firewall. Firewalls are separate components in the network architecture.
