An on-premises network has been extended to azure with a VPN/ExpressRoute. The routing and peering of VNets is setup and has been confirmed to be correct.
Which statement best describes the state of the traffic flow between the on-prem CVMs and the NC2 CVMs in Azure?
Network Security Groups (NSGs): NSGs control the inbound and outbound traffic to and from Azure resources. For traffic between on-premises CVMs and NC2 CVMs in Azure, the NSGs associated with the Flow Gateway VM's Internal NICs must be configured to allow the required traffic.
Editing NSGs: To enable traffic flow, specific rules must be added to the NSGs to permit traffic from the on-premises network to the NC2 environment. This includes specifying the appropriate source and destination IP ranges and the necessary ports and protocols.

A company needs to establish connectivity between the on-premises datacenter and Azure. The company does not have the infrastructure for a dedicated connection.
Which method will best satisfy this requirement?
VPN for Connectivity: A VPN (Virtual Private Network) allows secure connectivity between the on-premises datacenter and Azure over the public internet without requiring dedicated infrastructure.
Ease of Setup: VPNs are typically easier and quicker to set up compared to dedicated connections like ExpressRoute, making them suitable for organizations without existing dedicated connection infrastructure.

The cluster has the following configuration:
A Transit VPC exists as Default, but is additionally configured with a overlay-external-subnet-nonat overlay subnet
The ERP for the Transit VPC is 10.1.1.0/25
A User VPC exists named User_VPC_Prod
The ERP for the User VPC is 10.1.1.0/24
Outbound and inbound routes have been configured
A User VM NO-NAT subnet has been configured in the User VPC
The administrator has successfully created a VM and added the NIC associated with the NO-NAT subnet, but is not able to communication with other resources.
Which option will resolve this issue?
In this scenario, the issue arises from overlapping IP address ranges between the Transit VPC and the User VPC. Here's a detailed breakdown:
Understanding ERPs (Elastic Routing Prefixes):
The ERP for the Transit VPC is 10.1.1.0/25, which covers IP addresses from 10.1.1.0 to 10.1.1.127.
The ERP for the User VPC is 10.1.1.0/24, which covers IP addresses from 10.1.1.0 to 10.1.1.255.
IP Address Overlap:
Since 10.1.1.0/25 is a subset of 10.1.1.0/24, there is a significant overlap in the IP address ranges of these two ERPs.
This overlap can cause routing issues because the same IP address range is being used in both VPCs, leading to ambiguity in routing and communication.
Communication Issue:
When a VM in the User VPC tries to communicate with other resources, the network cannot accurately determine the correct route due to the overlapping IP address ranges.
This overlap prevents proper routing and results in the VM being unable to communicate with other resources as intended.
Resolution:
To resolve this issue, the ERPs must be in different CIDR ranges. This means the IP address ranges for the Transit VPC and the User VPC should not overlap.
For example, if the Transit VPC uses 10.1.1.0/25, the User VPC could use a different range such as 10.1.2.0/24 or any other range that does not overlap with 10.1.1.0/25.
By ensuring that the ERPs are in different CIDR ranges, the network can properly route traffic between the VPCs without any conflicts or ambiguities, thereby enabling the VM in the User VPC to communicate with other resources effectively.
An administrator is tasked with creating a new subnet for a group of VMs that require inbound internet access. Internal private addresses must be obscured to servers on the public internet.
Which network is best suited for satisfying this requirement?
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.

An administrator is planning on building the network prior to deploying a Nutanix cluster into Azure.
Which two components require their own vNets for NC2 in Azure? (Choose two.)
NC2 on Azure Deployment: Deploying Nutanix clusters in Azure involves configuring various components, each needing appropriate network isolation and configuration.
Components and vNets:
Bare-metal instance: Requires its own vNet to ensure proper network isolation and performance.
Prism Central: Needs a dedicated vNet to manage and monitor the Nutanix environment, ensuring it has the required network access and isolation.
Azure Load Balancer: Does not require its own vNet but needs to be associated with the appropriate vNet where services are deployed.
Virtual Network Gateway: Is used for VPN connections but does not necessitate a separate vNet; it operates within an existing vNet.
Network Isolation: Providing separate vNets for Bare-metal instances and Prism Central ensures optimal performance and management capabilities.
Conclusion: Both Bare-metal instances and Prism Central require their own vNets in the NC2 on Azure deployment.
