Nutanix NCP-CI-AWS - Nutanix Certified Professional - Cloud Integration - AWS (NCP-CI-AWS 6.10) Exam

The exhibit shows two cloud accounts, one for Azure and one for AWS, with their statuses indicated. The AWS cloud account status is marked as " U " (which likely stands for " Unavailable " or " Unreachable " ). This indicates that the AWS cloud account configuration is not properly connected or accessible.

Status Check:

The AWS cloud account is marked with an " U " status, meaning it is not active or accessible.

This status prevents the creation of an NC2 cluster because the necessary cloud resources cannot be allocated or managed without a proper connection.

Action:

The best course of action is to create a new cloud account in the organization. This involves setting up the cloud account details correctly and ensuring it is properly configured to communicate with Nutanix and AWS.

Steps to Create a New Cloud Account:

Log in to the Nutanix console.

Navigate to the " Organizations " section.

Select " Add Cloud Account " and provide the required AWS credentials and permissions.

Ensure the new cloud account is active and correctly configured.

Traffic from the on-premises network is not permitted by VM and Management security groups:

Ensure that the security groups assigned to the VMs and management interfaces in AWS allow inbound traffic from the on-premises network. Without appropriate security group rules, the traffic will be blocked.

The AWS VPC traffic is blocked by a firewall in the on-premises network:

Check if the firewall on the on-premises network is configured to allow traffic from the AWS VPC. Firewalls may have restrictive rules that block incoming traffic, preventing communication.

Refer to AWS documentation on security groups and firewalls and Nutanix documentation on configuring networking for NC2 clusters.

With the Nutanix AOS Pro licensing, several advanced features and add-on products become available. Specifically, in the AWS cluster deployment wizard, the following add-ons are available:

Files:

Nutanix Files provides a software-defined, scale-out file storage solution that simplifies the management and scaling of unstructured data.

Advanced Replication:

Advanced Replication features in Nutanix include synchronous and asynchronous replication capabilities, allowing for robust disaster recovery and data protection solutions.

DARE (Data-At-Rest Encryption):

DARE ensures that all data stored on Nutanix clusters is encrypted, providing a higher level of security for sensitive information.

These features are included in the AOS Pro licensing tier, offering enhanced data management, protection, and security capabilities.

Nutanix Best Practices for Advanced Features

To deploy NC2 in AWS using an existing VPC, the following AWS resources should be configured beforehand:

NAT Gateway: This allows instances in the private subnet to connect to the internet or other AWS services, while preventing the internet from initiating connections with those instances.

Public and Private Subnets: These are necessary to segregate the network traffic. Public subnets provide a direct route to the internet gateway, while private subnets are used for internal resources that do not need direct access to the internet.

Nutanix Support and Insights

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.

The error message in the image indicates that the cluster creation failed due to reaching the maximum retries for provisioning cluster nodes. Here are two possible scenarios that could lead to this issue:

Insufficient Permissions (Answer B):

If the AWS user or role used to create the cluster does not have sufficient permissions, it can result in failures during the provisioning process. Proper IAM policies must be attached to ensure that the necessary actions can be performed, such as launching instances, creating VPCs, or managing networking components.

AWS Quota Exceeded/Instance Limit Exceeded (Answer D):

AWS imposes quotas and limits on the number of instances and other resources that can be created within an account. If these quotas are exceeded, new instances cannot be provisioned, causing the cluster creation to fail. This can be resolved by requesting a quota increase from AWS.

While Nutanix provides multiple management interfaces, each serves a distinct purpose in the hybrid cloud lifecycle. Prism Central and Prism Element are used for managing software-level entities like VMs, storage containers, and replication policies. However, for thedefinitive status of the cluster ' s cloud infrastructure—including whether the bare-metal nodes are provisioned, if the cluster is in a " Healthy, " " Degraded, " or " Failed " state, or if a " boot timeout " has occurred—administrators must usethe NC2 Portal. The NC2 Portal acts as the primary orchestration layer that bridges Nutanix and AWS; it is the only console that displays specific cloud deployment tasks, hardware replacement status, and AWS-raised infrastructure events in a unified view.

When a catastrophic failure occurs, such as an entire AWS Availability Zone (AZ) becoming unavailable, the Cluster Protect feature provides a cloud-native orchestrated recovery path. The critical first step for an administrator to trigger the recovery workflow is to manually set the cluster to the " Failed " state within the NC2 console. Marking the cluster as failed signals the NC2 portal that the original infrastructure is non-functional and initiates the logic required to redeploy the cluster in a healthy, alternative AZ. Without this manual confirmation, the portal may continue attempting to reach the original nodes. Once the " Failed " state is confirmed, the portal provides the subsequent options to provision new bare-metal hardware and re-hydrate data from the Amazon S3 snapshots.

To ensure that NC2 VMs can access AWS resources without traversing the internet, the administrator can use AWS VPC Peering and Interface Endpoints. Both methods ensure that traffic stays within the AWS network, maintaining security and efficiency.

Interface Endpoint:

Interface Endpoints allow you to privately connect your VPC to supported AWS services. They use AWS PrivateLink to route traffic directly to services within the AWS network, bypassing the public internet.

Steps:

Create an interface endpoint for the required service in the AWS VPC console.

Ensure the security groups and route tables are configured to allow traffic to the interface endpoint.

VPC Peering:

VPC Peering allows the routing of traffic between VPCs using private IP addresses, without the need for internet gateways, NAT devices, or VPN connections.

Steps:

Create a VPC peering connection between the VPCs.

Update the route tables to direct traffic between the peered VPCs.

Ensure security group rules allow the necessary traffic between VPCs.

Ensure the specialist is assigned the RBAC role with proper permissions (Answer A):

Role-Based Access Control (RBAC) ensures that the specialist has the necessary permissions to troubleshoot and manage the NC2 environment. This avoids unnecessary privilege escalations and maintains security.

Confirm the Support Authorization on the organization is set to Full Access (Answer C):

Setting the Support Authorization to Full Access allows the Nutanix support specialist to have the required access to investigate and resolve issues in the environment. This is essential for effective troubleshooting.
