Nutanix NCP-CN - Nutanix Certified Professional - Cloud Native (NCP-CN-6.10)

The NKPA course recommends using a S3-compatible API for backup and restore operations in production NKP environments, as it integrates with Velero, NKP’s backup and restore tool. Velero supports S3-compatible storage (e.g., AWS S3, Nutanix Objects, or MinIO) as a backup storage location, allowing persistent data, including volumes and cluster resources, to be backed up and restored during disaster recovery scenarios. This approach ensures compatibility with cloud-native backup workflows and provides scalability and reliability for production use cases.

The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “For production backup and restore in NKP, use Velero with an S3-compatible API to store backups, ensuring persistent data availability during disaster recovery.” Nutanix Objects, which provides an S3-compatible API, is often used in Nutanix environments for this purpose, but any S3-compatible storage (e.g., an off-site S3 bucket) can be configured.

Incorrect Options:

A. Protection Domain: Protection Domains are a Nutanix AOS feature for VM-level replication, not for Kubernetes backup/restore.

B. Rook Ceph: Rook Ceph provides persistent storage for NKP clusters but is not a backup solution; it can be backed up using Velero with S3 storage.

C. External Storage Class: Storage Classes define how volumes are provisioned, not how they are backed up or restored.

The NKP documentation recommends using a combination of RBAC assignments and exported manifests to manage access across multiple clusters. By exporting the role assignments to YAML, the engineer can consistently apply these settings across the different environments, ensuring the new team has the necessary resources and limits. This approach is especially useful for environments with multiple clusters and standardized configurations.
