NCP-CI-AWS Exam Dumps - Nutanix Certified Professional (NCP) Questions and Answers

To deploy an NC2 cluster using an existing AWS network, the NAT Gateway should be placed in a public subnet. A public subnet is one that has a route to an Internet Gateway, allowing the NAT Gateway to provide outbound internet access for resources in private subnets. The NAT Gateway is used to enable instances in private subnets to access the internet while keeping them secure by not exposing them directly to the public internet.

Nutanix Cloud Clusters (NC2) on AWS Documentation

To create a cluster in Nutanix Cloud Integration with AWS, the role needed is Cluster Super Admin.

The Cluster Super Admin role provides the highest level of privileges required to perform critical operations such as creating, managing, and deleting clusters.

This role is essential for overseeing the cluster setup and configuration processes, ensuring the user has full control over the cluster lifecycle.

Refer to the Nutanix documentation on roles and permissions for NC2 on AWS for further details on the capabilities and required permissions for cluster creation.

The administrator has not created the necessary Security Group:

The error message indicates that the creation of network interfaces in a shared subnet requires specifying a security group. This means that the necessary security group has not been created or assigned to the network interfaces.

Creating the appropriate security group and ensuring it is associated with the network interfaces during cluster deployment should resolve this issue.

Refer to AWS documentation on security groups and network interface configuration and Nutanix documentation on prerequisites for deploying NC2 clusters in an existing AWS VPC.

For a VM deployed in an NC2 cluster on AWS to be accessed by resources within the on-premises datacenter, the security group associated with the User VM (UVM) subnet must allow inbound traffic on the specific ports required by the application.

If the security group rules do not permit inbound traffic on these ports, the communication will fail, even if other network configurations are correct.

The administrator should ensure that the UVM Security Group includes rules to allow inbound traffic for the application ' s required ports, facilitating proper communication between the VM and on-premises resources.

Refer to the AWS documentation on security group configurations and Nutanix NC2 documentation for details on configuring network access and security group rules.

WhenFlow Virtual Networking (FVN)is enabled for an NC2 cluster, Nutanix orchestrates the creation of aTransit VPCto handle traffic between the overlay and external networks. The core subnet created within this Transit VPC is namedoverlay-external-subnet-nonat. This subnet is critical as it serves as the entry and exit point for traffic that should not be subjected to address translation, such as traffic moving between the cloud overlay and an on-premises data center via a Transit Gateway or VPN. While administrators can manually add a NAT-enabled subnet later, the " nonat " variant is the primary default used to ensure that internal corporate communications remain transparent across the hybrid cloud boundary.

To manually create an AWS VPC with Public access to Prism Element for testing purposes, the following components must be created:

VPC: A Virtual Private Cloud to provide an isolated network for the resources.

Delegated Subnets: Subnets within the VPC to segment the network and allocate IP ranges.

Route Tables: To define routing rules for the subnets to ensure proper traffic flow.

NAT Gateway: To enable instances in the private subnets to access the internet.

Internet Gateway: To allow direct internet access to instances in the public subnets.

Load Balancer: To distribute traffic across multiple instances for improved availability and redundancy.

Refer to the AWS documentation on VPC creation and Nutanix documentation on network setup for Prism Element access.

To successfully onboard an AWS account into the NC2 console, the administrator must deploy a specific CloudFormation stack that establishes the necessary trust relationship and permissions. This process is highly sensitive as it involves the creation of IAM roles that allow Nutanix to orchestrate AWS resources. Consequently, the user executing this script must possessIAMFullAccessto create and modify these security identities andAWSCloudFormationFullAccessto manage the lifecycle of the stack itself. Without these high-level administrative permissions, the deployment will fail, preventing NC2 from obtaining the " secret " keys and roles required to launch bare-metal instances. This one-time setup is fundamental to the security architecture of the hybrid cloud environment.

Selecting the " I want to protect the cluster " option during the initial NC2 deployment wizard enables the underlying support for theCluster Protectfeature but does not fully finalize the protection policies. Once the bare-metal instances are provisioned and the Nutanix software is initialized, the administrator mustconfigure Cluster Protect after the deployment completes. This " Day Two " configuration involves specifying the Amazon S3 bucket that will serve as the backup target, defining the protection frequency (RPO), and selecting the specific User VMs or Prism Central data to be protected. Since the NCI Ultimate license already includes the advanced replication and protection features by default, no additional add-on purchase is required, but the functional setup of the backup policies remains a mandatory post-deployment task.

For issues related to cloud hardware support such as EC2 instances, VPC, etc., the public cloud vendor (AWS in this case) should be contacted. AWS provides support and documentation for their infrastructure and services, ensuring that users can get assistance for any hardware or cloud-specific queries.

Nutanix Support and Insights

Synchronous replication requires extremely low latency (sub-5ms) and a reliable high-speed connection between the primary and secondary storage controllers. While Flow Virtual Networking (FVN) supports various architectures, the most robust and supported way to enable synchronous replication for NC2 clusters in the same region is to ensure thatboth clusters reside within the same AWS VPC. This placement minimizes network hops and avoids the added latency that might be introduced by VPC Peering or a Transit Gateway between separate VPCs. By sharing the same VPC, the clusters can communicate via the same internal AWS network fabric, providing the deterministic performance required for zero-RPO data protection and Metro Availability configurations.
