Nutanix NCP-CN Exam Syllabus Topics:
TopicDetails
Topic 1
  • Manage Building an NKP Cluster: This section evaluates the skills of Kubernetes administrators and platform engineers in customizing and deploying NKP clusters. Candidates must show proficiency in tailoring cluster configurations to meet specific requirements and deploying Kommander, the management platform, while applying the appropriate licenses to enable cluster features and management capabilities.
Topic 2
  • Conduct NKP Fleet Management: This section tests the abilities of platform administrators and cloud operations engineers in managing multiple clusters as a fleet. It focuses on configuring workspaces to organize clusters, deploying workload clusters within these workspaces, and attaching or detaching clusters as needed. Additionally, candidates must be able to configure projects for workload segmentation and manage platform applications that support the overall NKP environment.
Topic 3
  • Prepare the Environment for an NKP Deployment: This section of the exam measures the skills of infrastructure engineers and cloud administrators and covers the initial setup tasks needed for NKP deployment. Candidates must demonstrate the ability to seed a private container registry, create a bootstrap Kubernetes cluster, and determine license tiers suitable for clusters. They also need to prepare a bastion host for secure access, build machine images or prepare nodes for deployment, and gather all necessary information to build a cluster on the target cloud or on-premises provider.
Topic 4
  • Perform Day 2 Operations: This part assesses the expertise of site reliability engineers and cluster operators in ongoing cluster management tasks after deployment. It includes configuring authentication and authorization mechanisms, setting up logging systems, and implementing cluster backup and recovery procedures. Candidates also need to demonstrate skills in monitoring cluster performance and health, configuring autoscaling to handle workload changes, and performing lifecycle management functions such as upgrades and maintenance.

Nutanix Certified Professional - Cloud Native v6.10 Sample Questions (Q38-Q43):NEW QUESTION # 38
A dev team needed to optimize their logging system to be more robust, because the CPU and memory limits were insufficient, which caused delays in log collection and processing during times of high demand.
After a deep performance analysis, they decided to increase the CPU limits from 1 to 4 and the memory from 1000Mi to 4Gi.
Which ConfigMap should the development team run with custom resource requests and limit values for fluentd?
  • A. bashCopy

NEW QUESTION # 39
A Platform Engineer is running a Kubernetes cluster version 1.28.1 on AWS that needs to be upgraded to version 1.29.9. This cluster was deployed with Nutanix NKP. Which two actions should the engineer take to complete this requirement? (Choose two.)
  • A. Upgrade Workers with nkp upgrade nodepool aws ${NODEPOOL_NAME} --cluster- name=${CLUSTER_NAME} --kubernetes-version=v1.29.9
  • B. Upgrade the Cluster with nkp update cluster aws --cluster-name=${CLUSTER_NAME} --ami AMI_ID
    --kubernetes-version=v1.29.9
  • C. Upgrade Workers with nkp update nodepool aws ${NODEPOOL_NAME} --cluster- name=${CLUSTER_NAME} --kubernetes-version=v1.29.9
  • D. Upgrade Control Planes with nkp update controlplane aws --cluster-name=${CLUSTER_NAME} -- ami AMI_ID --kubernetes-version=v1.29.9
Answer: A,D
Explanation:
The NKPA course details the process for upgrading an NKP-managed Kubernetes cluster, such as one running on AWS from version 1.28.1 to 1.29.9. Upgrading a Kubernetes cluster involves two distinct steps:
upgrading the control plane nodes and upgrading the worker nodes, ensuring minimal disruption and maintaining compatibility. The NKP CLI provides specific commands to handle these upgrades separately for AWS clusters.
* Upgrade Control Planes with nkp update controlplane aws --cluster-name=${CLUSTER_NAME}
--ami AMI_ID --kubernetes-version=v1.29.9 (Option B):The control plane must be upgraded first to the target Kubernetes version (1.29.9). The nkp update controlplane aws command updates the control plane nodes, specifying the cluster name, the new Kubernetes version, and an updated AMI (Amazon Machine Image) that supports the target version. The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: "To upgrade an NKP cluster on AWS, first update the control plane using nkp update controlplane aws --cluster-name <name> --ami <ami-id> --kubernetes-version <version> to ensure the control plane runs the desired Kubernetes version." The --ami flag is required to specify a compatible image for the upgraded control plane nodes.
* Upgrade Workers with nkp upgrade nodepool aws ${NODEPOOL_NAME} --cluster- name=${CLUSTER_NAME} --kubernetes-version=v1.29.9 (Option C):After the control plane is upgraded, the worker nodes in each node pool must be upgraded to match the control plane version.
The nkp upgrade nodepool aws command updates the specified node pool to the target Kubernetes version (1.29.9). The NKPA course notes: "Upgrade worker nodes using nkp upgrade nodepool aws
<nodepool-name> --cluster-name <cluster-name> --kubernetes-version <version>, which performs a rolling update to ensure minimal downtime." This command automatically handles the rolling update of worker nodes, replacing them with new nodes running the updated version. Note that the --ami flag is not required here, as NKP typically uses the same AMI as the control plane or retrieves a compatible one based on the version.
Incorrect Options:
* A. nkp update nodepool aws: The correct command is nkp upgrade nodepool, not nkp update nodepool. The NKPA course uses upgrade for version changes to node pools.
* D. nkp update cluster aws: This command is not the standard approach for upgrading Kubernetes versions in NKP. The course specifies separate commands for control plane and node pool upgrades to ensure a controlled process.

NEW QUESTION # 40
A Kubernetes administrator has been tasked with deploying a new cluster to AWS. The administrator has received the following requirements for this deployment:
* Region us-east-1
* AMI rhel8.6What is a requirement for deploying a new cluster in AWS?
  • A. Use --dry-run parameter
  • B. Set an export KUBECONFIG
  • C. Use --ami-format parameter
  • D. Set an export AWS_REGION
Answer: D
Explanation:
For deploying NKP clusters in AWS, setting the AWS_REGION environment variable is a key prerequisite to ensure that the AWS CLI and underlying deployment scripts know which region to target. This is essential for provisioning instances using the specified AMI.
Exact extract:
"Set the AWS_REGION environment variable to the appropriate region prior to deploying clusters to ensure proper interaction with the AWS API." Reference:
Nutanix Kubernetes Platform Administration (NKPA) 6.10 - "AWS Environment Configuration" NCP-CN 6.10 Study Guide - "Preparing the AWS Environment for NKP"
