Nutanix NCP-CN Exam With Confidence Using Practice Dumps

The exhibit shows the NKP UI with a list of clusters, including "arca," "demo," and "production," each with a three-dot menu on the right side. The NKPA course explains that to delete a cluster directly from the NKP UI, the engineer should use theDeleteoption available in the cluster’s three-dot menu. This action initiates the deletion process, removing the cluster from NKP management and freeing up any associated licenses (e.g., CPU core-based licenses, as per NKP licensing).

The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “To delete a cluster in NKP via the UI, navigate to the cluster list, click the three-dot menu for the target cluster (e.g., demo), and select ‘Delete’ to remove the cluster and its resources.” The UI in the exhibit aligns with this process, showing the three-dot menu next to the "demo" cluster, which includes the Delete option. This is the most straightforward method to delete the demo cluster and reallocate resources to the arca cluster.

Incorrect Options:

A. Download kubeconfig and use kubectl delete cluster: kubectl delete cluster is not a valid command for deleting NKP clusters. NKP uses the nkp CLI or UI for cluster deletion.

C. Select Detach and ask the cluster owner to delete: Detach is for external clusters (e.g., EKS), not NKP-managed clusters like "demo," which is on Nutanix infrastructure. Detaching does not delete the cluster.

D. SSH to kommander cluster and execute kubectl delete cluster: Kommander is a management component, but kubectl delete cluster is not a valid command for NKP cluster deletion.

The NKPA course specifies the supported operating systems for NKP clusters deployed using the Nutanix provisioning method (CAPX), which leverages Cluster API for Nutanix (CAPX) to provision clusters on Nutanix AHV. The supported OS platforms for CAPX areRocky LinuxandUbuntu, as these distributions are tested and optimized for Nutanix infrastructure and Kubernetes requirements.

Rocky Linux is a CentOS replacement adopted by Nutanix after CentOS 8’s end-of-life in 2021, providing a stable, enterprise-grade OS. Ubuntu, particularly LTS versions like 20.04 or 22.04, is widely supported due to its compatibility with Kubernetes and Nutanix AHV. The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “When deploying NKP with the Nutanix provisioning method (CAPX), the supported OS platforms are Rocky Linux and Ubuntu, ensuring compatibility with Nutanix AHV and Kubernetes.” These OS images are typically prepared using NKP Image Builder (NIB) to include necessary components like kubeadm and containerd.

Incorrect Options:

A. CentOS and Rocky Linux: CentOS 8 is no longer supported post-2021, and Nutanix has shifted to Rocky Linux.

C. Flatcar, Rocky Linux, and Ubuntu: Flatcar Container Linux is not a supported OS for CAPX in NKP deployments.

D. CentOS and Ubuntu: CentOS is not supported, as noted above.

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.
