Nutanix Certified Professional - Cloud Integration - Azure v6.7 NCP-CI-Azure Exam Questions

Answer : C

DNS Server Options:

Cloudflare: A public DNS service that operates over the internet.

Azure: Azure DNS operates within the Azure cloud and does not require VPN or ExpressRoute for connectivity within Azure.

On-premises: Requires a secure connection, such as VPN or ExpressRoute, to be accessible from Azure, as it resides outside the Azure cloud.

Google: Another public DNS service accessible over the internet.

Connectivity Requirements:

On-premises DNS: To integrate on-premises DNS with Azure, secure connectivity (VPN or ExpressRoute) is necessary to ensure seamless and secure communication between the on-premises infrastructure and Azure resources.

Conclusion: An on-premises DNS server would require VPN or ExpressRoute connectivity to be accessible and integrated with the Azure environment.

Answer : B

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.

Answer : B

Outbound Rule Necessity: For successful cluster deployment, certain outbound connections must be allowed to ensure proper download and configuration of resources.

Critical Destination: 'Https://downloads.cloud.nutanix.com/*' is a critical endpoint from which the Nutanix software and updates are downloaded during the cluster deployment process.

Functionality: Ensuring an outbound rule for this destination allows the deployment to fetch necessary files and updates, enabling smooth cluster setup and operation.

Other Destinations:

Https://portal.nutanix.com/: Used for accessing the Nutanix portal, not directly related to deployment downloads.

Https://support.nutanix.com/: Used for support-related tasks, not for deployment-specific downloads.

https://nutanix.dev/: Related to development and API documentation, not necessary for initial deployment.

Conclusion: Outbound connectivity to 'Https://downloads.cloud.nutanix.com/*' is essential for downloading deployment resources.

Answer : D

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.

Answer : D

NAT Based Network: A NAT-based network is designed to provide inbound and outbound internet access while obscuring the internal private addresses. This setup uses Network Address Translation (NAT) to map internal IP addresses to a public IP address, ensuring that internal addresses are not exposed to the public internet.

Security and Connectivity: NAT provides a layer of security by hiding internal IP addresses and allowing controlled access to external resources. This configuration is well-suited for VMs that need to communicate with servers on the public internet while maintaining the privacy of their internal network addresses.

Answer : C

Cluster State Requirement: To expand a cluster, it must be operational and in a connected state to ensure seamless integration of additional nodes.

Cluster Stopped State: If the cluster is stopped, it cannot perform expansion operations.

Minimum Nodes Requirement: There is no minimum node count prerequisite for expanding the cluster as long as the cluster is connected.

Cluster Connected State: Ensuring the cluster is connected verifies that it is operational and can communicate with additional nodes being added.

Conclusion: The cluster must be in a Cluster Connected state to expand successfully.
