Nutanix NCP-CN Exam Syllabus Topics:

TopicDetails
Topic 1
  • 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 2
  • 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 3
  • 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 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 (Q19-Q24):

NEW QUESTION # 19
In a telecom company, two teams were working on the development of two different applications:
* ApplicationA
* ApplicationBApplicationA's development team was excited about the release of their new functionality. However, upon deploying their application, they noticed that performance was slow.
After investigating, they discovered that the ApplicationB team was consuming the majority of the cluster's resources, affecting all other teams. How can this problem be mitigated?

Answer: A

Explanation:
The NKPA course addresses resource contention in Kubernetes clusters, where one application (e.g., ApplicationB) consumes excessive resources, impacting others (e.g., ApplicationA). To mitigate this, the course recommends implementing Quotas and Limit Ranges.
* Resource Quotas restrict the total amount of CPU, memory, and other resources a namespace can consume, ensuring fair resource allocation across teams.
* Limit Ranges set minimum and maximum resource limits for individual pods and containers within a namespace, preventing any single application from monopolizing resources.
The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: "To prevent resource contention in NKP clusters, apply Resource Quotas to limit namespace resource usage and Limit Ranges to enforce pod and container resource boundaries." For example, the administrator can create a ResourceQuota to cap ApplicationB's namespace resource usage and a LimitRange to restrict its pod resource requests/limits, ensuring ApplicationA has sufficient resources.
Incorrect Options:
* B. Setting up Network Policies: Network Policies control network traffic, not resource usage.
* C. Configuring RBAC: RBAC manages access permissions, not resource allocation.
* D. Implementing Continuous Deployment (CD): CD automates deployments but does not address resource contention.

NEW QUESTION # 20
A Platform Engineer is attaching existing Kubernetes clusters to NKP, but a particular Kubernetes Amazon EKS cluster is getting errors with application deployments. These errors are related to persistent volumes.
What could be the issue, and what can the engineer do?

Answer: A

Explanation:
When attaching an Amazon EKS cluster to NKP for fleet management, persistent volume (PV) errors during application deployments often indicate issues with storage configuration. The NKPA course identifies a common cause: the absence of a default StorageClass. Kubernetes requires a default StorageClass to automatically provision PVs for PersistentVolumeClaims (PVCs) when none is specified. Without a default, applications fail to bind PVCs, resulting in deployment errors.
The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: "For attached EKS clusters, ensure a default StorageClass is configured to support dynamic provisioning of persistent volumes. Review existing StorageClasses and set one as default using the storageclass.kubernetes.io/is-default-class annotation." The engineer should run kubectl get storageclass to list available StorageClasses, verify their configurations, and set one as default by patching it with kubectl patch storageclass <name> -p '{"metadata": {"annotations":
{"storageclass.kubernetes.io/is-default-class":"true"}}}'. In EKS, the default StorageClass is typically backed by Amazon EBS (e.g., gp2 or gp3).
Incorrect Options:
* A. The storage appliance is having issues: This assumes a hardware issue, which is not indicated by PV errors. The NKPA course suggests checking Kubernetes configurations first.
* B. There is no compatible storage: EKS supports EBS and EFS, which are compatible with NKP. The issue is likely configuration, not compatibility.
* D. There could be a misconfiguration in the ConfigMap: ConfigMaps are not directly related to PV provisioning. The NKPA course points to StorageClass issues for PV errors.

NEW QUESTION # 21
An infrastructure team has configured a Backup Storage Location on an existing AWS bucket and created a backup named testbackup. What command can the team use to view the backup?

Answer: D

Explanation:
The Nutanix Kubernetes Platform (NKP) integrates Velero, an open-source tool, for backup and restore operations as part of its Day 2 operations. The NKPA course explains that after configuring a Backup Storage Location (e.g., an AWS S3 bucket) and creating a backup, administrators can view details of the backup using the Velero CLI. The correct command to view the details of a backup named testbackup is velero backup describe testbackup. This command provides a detailed description of the backup, including its status, resources included, and storage location.
The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: "To inspect a Velero backup in NKP, use the velero backup describe <backup-name> command to display detailed information about the backup, such as its creation time, expiration, and included resources." The backup name (testbackup) is specified as created by the team, and no prefix like aws-velero- is indicated in the question, making option C the correct choice.
Incorrect Options:
* A. kubectl get backupstoragelocations -n ${testbackup} -o yaml: This command retrieves Backup Storage Location objects, not backup details. The namespace ${testbackup} is also incorrect, as Velero resources are typically in a specific namespace (e.g., velero).
* B. velero backup describe aws-velero-testbackup: The backup name is testbackup, not aws-velero- testbackup. The NKPA course does not indicate any prefix for the backup name.
* D. kubectl get backupstoragelocations -n ${WORKSPACE_NAMESPACE} -o yaml: This retrieves Backup Storage Locations, not the backup itself, and does not provide backup details.

NEW QUESTION # 22
A company recently deployed NKP. A Platform Engineer was asked to attach the existing Amazon EKS. A workspace and project were created accordingly, and resource requirements were met. What does the engineer need to do first to prepare the EKS clusters?

Answer: D


NEW QUESTION # 23
A Platform Engineer for an organization needs to deploy NKP into AWS while using custom credentials for authenticating. Which flag should the engineer use when starting to bootstrap the cluster installation?
--aws-profile=<my-profile><br> B. --cloud-credentials=<my-profile><br> C. --with-aws-bootstrap- credentials=true<br> D. --aws-access-key=<aws access="" key=""> --aws-secret-key=<aws secret="" key=""
></aws></aws></my-profile></my-profile>

Answer:

Explanation:
When deploying NKP to AWS, the bootstrap process requires AWS credentials to interact with AWS APIs for provisioning resources like EC2 instances. The NKPA course specifies that the nkp CLI supports the -- aws-profile flag to specify a custom AWS profile for authentication. This profile, defined in the AWS credentials file (~/.aws/credentials), contains the access key and secret key for the desired AWS account.
The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: "To deploy NKP on AWS with custom credentials, use the --aws-profile=<profile-name> flag during the nkp create bootstrap command to reference a specific AWS profile." This approach leverages the AWS CLI's profile management, ensuring secure and flexible credential handling. For example, the command would be nkp create bootstrap --aws-profile=my- profile --kubeconfig bootstrap-cluster.conf.
Incorrect Options:
* B. --cloud-credentials=<my-profile></my-profile>: This flag is not used by the nkp CLI. The NKPA course specifies --aws-profile for AWS.
* C. --with-aws-bootstrap-credentials=true: This flag does not exist in the NKPA documentation for NKP bootstrap.
* D. --aws-access-key=<aws access="" key=""> --aws-secret-key=<aws secret="" key=""></aws><
/aws>: While these flags may be used in some tools, the NKPA course recommends using --aws-profile to avoid hardcoding sensitive credentials.
