Free Practice Questions for Nutanix NCP-CI-Azure Exam

Free Trial Expiration:Once the NC2 free trial period expires, the administrator needs to switch to a paid subscription plan to continue using all the features and functionalities provided by Nutanix NC2.

Paid Subscription Benefits:Transitioning to a paid subscription ensures uninterrupted access to NC2 features, support, and updates, maintaining the operational capabilities of the existing clusters.

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.

Scenario Analysis:

A. Connectivity between sites already provides encryption: Using VTEP in this scenario is advantageous because VTEP does not inherently provide encryption. If encryption is already provided, VTEP can be effectively used without additional security concerns.

D. Multiple remote Availability Zones exist to add to the same VTEP-based extended Layer 2 subnet: VTEP is well-suited for scenarios where multiple remote Availability Zones need to be connected to the same extended Layer 2 subnet. This allows for efficient management and seamless connectivity across different zones.

Scenarios B and C:

B. Only one remote Availability Zone exists that needs the subnet extended: This scenario does not leverage the strengths of VTEP, as it is better suited for multiple zones.

C. Connectivity between sites already does not provide encryption: Using VTEP without existing encryption is not ideal as VTEP itself does not encrypt the traffic.

Conclusion: VTEP is advantageous when encryption is already in place and when multiple remote zones need to be connected to the same extended subnet.

Check the list of regions specified under the NC2 organization cloud account:The list of available regions in the NC2 console might be restricted based on the configuration of the cloud account associated with the NC2 organization. Verifying this list ensures that the desired region is included and available for cluster creation.

Ensure that the Azure region is whitelisted for use by Microsoft in the subscription:Sometimes, specific regions need to be explicitly enabled or whitelisted in the Azure subscription for certain services. This step ensures that the required region is permitted for use within the Azure subscription, allowing the NC2 cluster to be created in that region.

Allowlisting the Azure Subscription:This step ensures that the Azure subscription is recognized and permitted by Nutanix Cloud Clusters (NC2). Without allowlisting, the necessary resources and permissions within the Azure subscription may not be available for NC2, potentially blocking the creation and management of clusters.

Creating an App Registration:This involves setting up an application within Azure Active Directory (AAD) to enable secure communication between NC2 andAzure. The app registration process includes assigning permissions and obtaining necessary authentication credentials, facilitating the interaction and management of Azure resources by NC2.

Azure Subscription Validation: When deploying an NC2 cluster, the Azure subscription must be validated and allowlisted by Microsoft. This is a crucial step to ensure that the necessary permissions and configurations are set up for the deployment.

Booting State Issue: If the nodes are stuck in the Booting state, it often indicates that the subscription has not been properly validated and allowlisted. This prevents the deployment from progressing as required resources and permissions are not fully accessible.

Checking Allowlisting Status: Administrators should verify that their subscription has been allowlisted by contacting Azure support or checking the status through the Azure portal.

Resolution: Once the subscription is validated and allowlisted by Microsoft, the deployment should proceed without the nodes getting stuck in the Booting state.

In the scenario presented, the NC2 cluster was initially deployed with two Flow Gateways (FGW1 and FGW2) in HA. After adding four bare-metal nodes and additional workloads, two more Flow Gateways (FGW3 and FGW4) were added to handle the increased bandwidth for north/south traffic. Given the configuration, the existing workloads can utilize all available Flow Gateways (FGW1, FGW2, FGW3, and FGW4) for No-NAT (routed) traffic paths. This setup allows for Equal Cost Multipath (ECMP) routing, distributing traffic load across all Flow Gateways.

Jump Host Deployment:A Jump Host is a secure server used to access other systems in a network. In the context of an NC2 cluster on Azure, it serves as an intermediary for accessing Prism Element and Prism Central.

Flexible Deployment Options:The Jump Host can be deployed in either the Prism Central VNet or an external VNet, providing flexibility in network design and access strategies. This allows the organization to choose the most suitable network for deploying the Jump Host based on their security and connectivity requirements.

Storage Capacity Requirement: The requirement specifies that the bare metal instance must support up to 20 TB of storage capacity.

Instance Selection: Among the provided options, the AN36P instance is designed to support higher storage capacities and performance needs.

AN36P Capabilities: The AN36P instance is optimized for storage-intensive applications and provides the necessary hardware specifications to handle up to 20 TB of storage.

Comparison with Other Instances:

ND96asr: Typically optimized for GPU workloads rather than storage.

AN36: May not meet the 20 TB storage requirement.

HB176rs: Geared towards high-performance computing rather than large storage capacities.

Conclusion: Based on the requirements and instance specifications, AN36P is the most suitable choice for supporting up to 20 TB of storage.
