NCP-CN Exam Dumps : Nutanix Certified Professional - Cloud Native (NCP-CN-6.10)

The NKPA course specifies that air-gapped deployments and centralized fleet management of multiple clusters are advanced features of NKP, requiring theNKP Ultimatelicense tier. The Ultimate tier includes support for air-gapped environments (via Air-Gapped Bundles) and fleet management capabilities, such as attaching and managing multiple clusters under a single management plane, which is critical for the national defense company’s scenario.

The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “The NKP Ultimate license tier is required for air-gapped deployments and centralized management of multiple Kubernetes clusters, providing the necessary tools for secure, isolated environments.” This ensures the company can deploy and manage their three clusters in an air-gapped setup while maintaining strict data security.

Incorrect Options:

A. NKP Starter: The Starter tier lacks air-gapped and fleet management features.

C. NKP Pro: The Pro tier may support some advanced features but not air-gapped deployments or full fleet management.

D. NKP UI: This is not a license tier; it’s a UI component of NKP.

The kube-prometheus-stack is a key component of NKP’s monitoring stack, providing tools for metrics collection, visualization, and alerting. The NKPA course explains thatAlertmanager, a component of the kube-prometheus-stack, is responsible for handling alerts generated from Prometheus metrics. It aggregates, deduplicates, and routes notifications to the appropriate channels (e.g., email, Slack, PagerDuty), ensuring that the Platform Engineer stays informed of critical events and anomalies in the NKP cluster, such as node failures, resource exhaustion, or application errors.

The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “Alertmanager in the kube-prometheus-stack processes alerts from Prometheus, enabling administrators to stay informed of cluster events through configured notification channels.” By configuring Alertmanager with appropriate routing rules and receivers, the engineer can receive real-time notifications about cluster events, driving proactive management and productivity.

Incorrect Options:

A. prometheus-operator: The operator manages Prometheus and related resources but does not directly handle event notifications.

B. service monitors: Service monitors define how Prometheus scrapes metrics, not how events are communicated.

D. node-exporter: Node-exporter collects node-level metrics, not event notifications.

A bastion host in a dark site environment serves as a secure entry point for managing the NKP deployment, providing access to the cluster infrastructure without direct Internet connectivity. The NKPA course outlines the prerequisites for preparing a Linux VM as a bastion host, focusing on secure access and time synchronization, which are critical for air-gapped Kubernetes deployments.

Get or create SSH Keys (Option B):The bastion host requires SSH keys to enable secure, passwordless access to the NKP cluster nodes and other infrastructure components (e.g., Nutanix AHV hosts). The NKPA course specifies that SSH keys must be generated or obtained and configured on the bastion host to facilitate secure communication during deployment and management tasks. The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “For a bastion host in an NKP dark site deployment, ensure SSH keys are created or obtained to enable secure access to cluster nodes and infrastructure.” The engineer can generate SSH keys using ssh-keygen and distribute the public key to the target systems.

Enable NTP Service (Option D):Time synchronization is essential in Kubernetes clusters to ensure consistent logging, certificate management, and scheduling. In a dark site with no Internet access, the bastion host must be configured to synchronize time with an internal NTP (Network Time Protocol) server or act as an NTP server itself. The NKPA course emphasizes enabling the NTP service on the bastion host to maintain accurate time across the air-gapped environment. The NCP-CN 6.10 Study Guide notes: “Enable the NTP service on the bastion host to ensure time synchronization in a dark site NKP deployment, as Kubernetes requires accurate time for proper operation.” The engineer can enable NTP using commands like systemctl enable ntpd and configure it to use an internal time source.

Incorrect Options:

A. Install LDAP Server: LDAP is used for centralized authentication, but it is not a requirement for a bastion host in an NKP dark site deployment. The course focuses on SSH access instead.

C. Install Docker: While Docker is needed on Kubernetes nodes for container runtimes, the bastion host’s role is to provide secure access and management, not to run containers.
