An administrator has been asked to create a cluster to support new workloads.
What are the maximum number of nodes supported in AWS?
- A . 14 nodes
- B . 18 nodes
- C . 24 nodes
- D . 28 nodes
C
Explanation:
The maximum number of nodes supported in an NC2 cluster on AWS is 24 nodes. This limit ensures optimal performance and manageability within the AWS infrastructure while leveraging the benefits of the Nutanix architecture.

If an administrator deploys an NC2 cluster using an existing AWS network, in which type of subnet should the administrator deploy the NAT Gateway?
- A . Isolated subnet
- B . Private subnet
- C . VPN-only subnet
- D . Public subnet
D
Explanation:
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.

Regarding a cloud cluster, which two upgrades can be performed using LCM? (Choose two.)
- A . AHV
- B . NBA
- C . BIOS
- D . NCC
AC
Explanation:
AHV (Answer A):
AHV (Acropolis Hypervisor) can be upgraded using Lifecycle Manager (LCM). LCM simplifies the upgrade process and ensures that all components are updated in a coordinated manner.
BIOS (Answer C):
BIOS upgrades can also be performed using LCM. This helps in maintaining hardware compatibility and performance by ensuring that the latest firmware is installed.

An administrator is experiencing problems with several operations, including VM IP address assignment validations, VM power-on and VM power-off operations.
Whenever a related operation is performed, an alert is generated in the NC2 console indicating that the Cloud API endpoints are unavailable.
The issue was further investigated and it was determined that NC2 is unable to make API calls to the underlying cloud infrastructure due to network connectivity misconfigurations.
Which two connectivity misconfigurations could be causing this issue? (Choose two.)
- A . AWS VPC endpoints are used for connectivity to AWS services.
- B . Subnets are connected to the Internet via NAT gateways.
- C . Route tables for cloud subnets contain incorrect route entries.
- D . IAM roles and policies are incorrectly configured.
CD
Explanation:
Route tables for cloud subnets contain incorrect route entries:
If the route tables associated with the cloud subnets contain incorrect route entries, the NC2 cluster might not be able to reach the necessary AWS services or endpoints. Correct route entries are crucial for ensuring proper communication between the NC2 cluster and the underlying AWS infrastructure.
IAM roles and policies are incorrectly configured:
Incorrectly configured IAM roles and policies can prevent NC2 from making API calls to AWS services. These roles and policies must be properly set up to allow the necessary permissions for NC2 to interact with AWS resources and perform required operations.
Reference: Refer to the AWS documentation on route table configuration and IAM roles and policies, and Nutanix documentation on NC2 cloud connectivity and permissions.
Which entity should be contacted for cloud hardware supported (EC2 instances, VPC, etc) related to NC2?
- A . Partner
- B . Public Cloud Vendor
- C . Internal IT Operations team
- D . Nutanix
B
Explanation:
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.

HOTSPOT
An administrator needs to recover a cluster protected using the Cluster Protect feature. The Prism Central instance was not on the failed cluster.
Which steps, in order, should the administrator perform to recover the cluster?
Step 1: Set the cluster to the Failed state using the NC2 console to start the recovery workflow.
Step 2: Redeploy the cluster using the NC2 console.
Step 3: Redeploy the Multicloud Snapshot Technology.
Step 4: Recover UVM data by running CLI commands.
Set the cluster to the Failed state using the NC2 console to start the recovery workflow: This step involves marking the cluster as failed to initiate the recovery process.
Redeploy the cluster using the NC2 console: Once the cluster is marked as failed, the next step is to redeploy it using the tools available in the NC2 console.
Redeploy the Multicloud Snapshot Technology: After the cluster is redeployed, the Multicloud Snapshot Technology needs to be redeployed to ensure data consistency and availability.
Recover UVM data by running CLI commands: The final step is to recover the User VM (UVM) data by executing the necessary CLI commands to restore the data from the snapshots or backups.

Which entity should be contacted for AOS software supported related to NC2?
- A . Internal IT Operations team
- B . Nutanix
- C . Partner
- D . Public Cloud Vendor
B
Explanation:
For AOS software support related to NC2, the appropriate entity to contact is Nutanix. Nutanix provides comprehensive support for their software, including the Acropolis Operating System (AOS) used in NC2 deployments.
Support Scope:
Nutanix offers support for the deployment, configuration, and management of NC2 clusters, including any issues related to AOS software.
This includes troubleshooting, updates, and technical assistance.
Why Not Other Options:
Internal IT Operations team: Typically handles internal issues but does not have the specialized knowledge or resources for AOS software support.
Partner: May provide support but would ultimately escalate issues to Nutanix for software-specific concerns.
Public Cloud Vendor: Manages infrastructure-related issues but does not provide support for Nutanix AOS software.

An administrator has deployed NC2 on AWS. The cluster deployment completed successfully. After deployment, the administrator created a subnet in AWS, added it as a network in Prism Element, deployed Prism Central using the newly-configured network, and registered the cloud cluster with it.
The on-premises network and AWS are connected via a Site-to-Site VPN. Cluster nodes, CVM, and Prism Central can communicate with each other, but cannot be accessed from the on-premises network.
What two issues might be the cause of this problem? (Choose two.)
- A . AWS Direct Connect must be used to establish connection between AWS and on-premises
- B . Traffic from the on-premises network is not permitted by VM and Management security groups.
- C . The AHV firewall is blocking traffic from the on-premises network.
- D . The AWS VPC traffic is blocked by a firewall in the on-premises network.
BD
Explanation:
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.
Reference: Refer to AWS documentation on security groups and firewalls and Nutanix documentation on configuring networking for NC2 clusters.
An administrator is investigating reports of network congestion on their NC2 deployment.
As part of the investigation, a packet capture is taken from a group of user VMs. During the analysis of the packet capture, it is observed that user VMs are receiving multicast traffic unexpectedly.
What action should the administrator take to resolve the issue?
- A . Disable DHCP snooping on the upstream network
- B . Enable IGMP snooping on the AHV hosts
- C . Enable DHCP snooping on the upstream network
- D . Disable IGMP snooping on the AHV hosts
B
Explanation:
Enable IGMP snooping on the AHV hosts:
IGMP (Internet Group Management Protocol) snooping is a feature that listens to IGMP traffic between hosts and routers. By enabling IGMP snooping on the AHV (Acropolis Hypervisor) hosts, the switch can intelligently forward multicast traffic only to the ports that have requested it.
This reduces unnecessary multicast traffic on the network and prevents congestion by ensuring that multicast packets are only delivered to the appropriate endpoints.
Reference: Refer to the Nutanix documentation on network configuration and best practices for managing multicast traffic.
