Nutanix Updated NCP-CI-AWS Exam Questions and Answers by ari

The alert indicates a potential issue with the VPC/Subnet settings, preventing the cluster nodes from contacting Nutanix services.

To resolve this, the administrator needs to ensure that the subnet 10.0.1.0/24, which is assigned for Bare metal hosts, has an outbound Internet connection.

This connection is necessary for the cluster nodes to communicate with external Nutanix services for updates, license validation, and other essential operations.

Verify that there are appropriate route tables and security group rules allowing outbound traffic to the Internet from the 10.0.1.0/24 subnet.

Ensure that there is either an Internet Gateway (IGW) attached to the VPC or a NAT Gateway configured if using private subnets.

Refer to the Nutanix documentation and AWS VPC configuration guides to ensure proper Internet connectivity and routing setups.

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.

Configuring a proxy server for NC2 on AWS is a critical security step for organizations requiring centralized traffic inspection. This capability is specific to certain software versions and network architectures.

Support for proxy servers was introduced inAOS 6.7.1.6and requires the deployment to be within a user-created VPC (Bring Your Own VPC), rather than an auto-created VPC managed by Nutanix. It is important to note thatFlow Virtual Networking (FVN), which provides advanced overlay networking capabilities, currently does not support the use of a proxy server for cluster traffic. Therefore, administrators must choose between the advanced features of FVN and the traffic routing control provided by a proxy server based on their specific organizational requirements.

When creating a new NC2 cluster using an existing AWS VPC infrastructure, two private subnets are needed. These subnets are used as follows:

One private subnet for user VMs, which houses the virtual machines that users interact with.

Another private subnet for cluster management, which is used for internal cluster operations and management tasks, ensuring that management traffic is isolated from user traffic for security and performance reasons.
