NCP-CI-Azure Exam Dumps - Nutanix Certified Professional Questions and Answers

Floating IP Address Limitation:The cluster already has 25 floating IP addresses in use by other VMs. If the administrator cannot assign a floating IP address to the new VM, it is because the pool of available floating IPs is exhausted.

Requesting Additional Floating IPs:To resolve this issue, the administrator needs to request additional floating IP addresses to be allocated to the NAT subnet. This will ensure that there are enough IP addresses available for all VMs requiring inbound connectivity.

Initial Access: To gain access to the NC2 console, users need to create an account on the Nutanix platform.

My Nutanix Account: Creating a My Nutanix account provides access to the Nutanix console, support, and other resources.

Free Trial and Billing Portal: Starting a free trial or accessing the billing portal can be subsequent steps but require an initial account.

Support Case: Opening a support case is not necessary for initial access but might be needed for specific issues later.

Conclusion: Creating a My Nutanix account is the first step to accessing the NC2 console and other Nutanix services.

Getting Started with Nutanix NC2

Flow Virtual Networking: Nutanix Flow Virtual Networking allows for the creation of overlay networks to segment and manage network traffic.

Network Types:

Underlay: Refers to the physical network infrastructure.

Overlay: Logical network built on top of the physical infrastructure, providing flexibility for creating isolated subnets and accommodating different workloads.

VPC: Virtual Private Cloud, a network within a public cloud provider.

VNET: Azure-specific virtual network.

Requirement: Creating a subnet for new workloads within Flow Virtual Networking suggests using an overlay network for logical separation and management.

Conclusion: An overlay network within Flow Virtual Networking will satisfy the task of accommodating a new type of workload in the NC2 Azure instance.

NATed Path Configuration: When using the NATed Path, it is essential to ensure that traffic can flow out of the Flow gateway VM to external networks.

Default Route: Adding a default route on the Nutanix User VPC ensures that all outbound traffic is directed to the appropriate network gateway.

Configuration Steps:

Navigate to the routing settings of the Nutanix User VPC.

Add a default route with the destination of 0.0.0.0/0, pointing to the External Overlay network.

Security Group Settings:

Ensure that the External Flow Gateway Security Group on the External NIC allows outbound traffic.

Ensure that the Internal Flow Gateway Security Group on the internal NIC allows outbound traffic (if needed for internal network flows).

Conclusion: Properly configuring the default route on the Nutanix User VPC enables outbound traffic flow via the NATed Path through the External Overlay network.

Minimum Node Requirement:For production deployments, Nutanix typically requires a minimum of three nodes to ensure high availability and fault tolerance within the cluster.

Azure Ready Nodes:Deploying at least three Azure Ready Nodes allows the cluster to provide redundancy, ensuring that the failure of a single node does not affect the overall availability and performance of the cluster.

High Availability and Redundancy Best Practices

Cloud Hardware Support: For issues related to cloud hardware, such as EC2 instances or VPC configurations, the responsible entity is typically the public cloud vendor.

Nutanix Responsibility: Nutanix manages the software layer and integration aspects of the NC2 service, but the underlying hardware support is managed by the cloud provider (e.g., AWS, Azure).

Support Process:

Public Cloud Vendor: Contact the public cloud vendor for issues directly related to the hardware, as they own and manage the physical infrastructure.

Nutanix: For software and configuration issues specific to the NC2 service, contact Nutanix support.

Conclusion: For cloud hardware-related support, the appropriate contact is the public cloud vendor.

To verify that the NC2 specialist has access to the necessary organizations for troubleshooting the issue, the administrator should:

Confirm that theSupport Authorizationon the organization is set toFull Access. This ensures that the NC2 specialist has the required permissions to access the necessary resources and perform the necessary actions to resolve the issue.

Providing login credentials or adding the specialist as an admin user is not recommended due to security and privacy concerns. Ensuring the specialist is assigned the correct RBAC role is another valid approach but confirming the support authorization directly ensures they have the needed access.

Private Endpoint:Private Endpoints allow secure access to Azure services over a private network connection. They do not typically appear on delegated subnets, which are used for specific Azure services.

Prism Central Connectivity:Prism Central can be connected to a private endpoint to ensure secure communication without exposing it to the public internet. This setup ensures secure and private management of the Nutanix environment.

Flow Gateway VMs: Flow Gateway VMs are used to manage and route network traffic within an NC2 on Azure cluster, ensuring sufficient bandwidth for workloads.

Scalability: To ensure enough available bandwidth, multiple Flow Gateway VMs can be deployed.

Maximum Limit: The highest number of Flow Gateway VMs that can be deployed within an NC2 on Azure environment is 6, providing the necessary capacity to handle high traffic volumes and ensure optimal performance.

Conclusion: Deploying up to 6 Flow Gateway VMs ensures adequate bandwidth for NC2 workloads.

Port Requirements: The specified ports (22, 2009, 2020, 2049, 3260, 9440) are commonly used for various services and require TCP communication.

Port 22: SSH

Port 2009: Used for Nutanix internal communication

Port 2020: Nutanix services

Port 2049: NFS

Port 3260: iSCSI

Port 9440: Nutanix Prism management

Communication Type: To ensure proper disaster recovery setup, bi-directional communication is needed to allow traffic to flow both from on-premises to Azure and vice versa.

TCP Protocol: These ports use the TCP protocol, which provides reliable communication between devices.

Conclusion: Creating a bi-directional (TCP) rule on the firewall allows the necessary communication for disaster recovery processes.
