For a VM to be accessible over the internet through a load balancer, the VM itself must have a public IP address.

In this case, the health check for the VM target is failing and the DNS returns a " NOT Found " message because web-1 does not have a public IP assigned.

Without a public IP, the load balancer cannot route traffic to web-1 from the internet.

Assigning a public IP to web-1 ensures that the VM can be accessed via the load balancer, resolving the connectivity issue.

Refer to the AWS documentation on network load balancers and public IP assignments, and Nutanix documentation on VM network configurations.

AWS Direct Connect allows companies to create private, dedicated connections between their data centers and AWS. This bypasses the internet and provides a more reliable and faster network connection directly to AWS services, including S3.

Cluster Protect in an NC2 environment can protect and recover the following services and their associated metadata:

VM Templates: Ensures that templates used for creating virtual machines are backed up and recoverable.

Files: Protects data stored in Nutanix Files, ensuring that file services are backed up and can be restored as needed.

Nutanix Cloud Clusters on AWS Administration

To achieve anRTO (Recovery Time Objective)as low as15 minutesusing Multicloud Snapshot Technology, aPilot Light Deploymentis essential. In this model, a minimal Nutanix cluster is always active in the cloud. This active presence ensures that the Prism Central management layer is ready to receive recovery commands and that the storage containers are already mounted. Because the " compute " is already provisioned, the recovery process simply involves hydrating the snapshots from the S3 bucket and powering on the VMs according to the Recovery Plan. A " Zero Compute " model would exceed this RTO because the time required to provision new bare-metal instances from AWS and initialize the Nutanix software can take significantly longer than 15 minutes.

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 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.

Nutanix Best Practices for Cloud Account Management

To ensure continuous availability and maintain the specified Replication Factor (RF) during maintenance or hardware issues, Nutanix follows a proactive " provision before removal " logic for host replacement in the cloud. The correct operational sequence begins with adding a new host to the cluster first. This step expands the cluster ' s capacity and ensures there is a destination ready for data synchronization. Once the new host is fully integrated into the storage fabric, the system migrates the virtual machines and their associated data away from the degraded or old host. Only after the old host has been completely evacuated and the cluster returns to a healthy, balanced state does the NC2 console conclude the operation by removing the old host from the cluster configuration.

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.

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.
