After creating a new Nutanix User VPC, what is needed to allow traffic to flow out of the Flow gateway VM when using the NATed Path?

1. A. Add a default route on the Transit VPC of 0.0.0.0/0 to the Flow Gateway.
2. B. Add a default route on the Transit VPC of 0.0.0.0/0 to the Flow Gateway.
3. C. Add a default route on the Nutanix User VPC of 0.0.0.0/0 to the External Overlay network.
4. D. Edit the External Flow Gateway Security Group on the External NIC to allow outbound traffic.Edit the Internal Flow Gateway Security Group on the internal NIC to allow outbound taffic

Correct Answer: C
✑ 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:
✑ Security Group Settings:
✑ Conclusion: Properly configuring the default route on the Nutanix User VPC enables outbound traffic flow via the NATed Path through the External Overlay network.

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?

1. A. The ERP in the User VPC must be from a different CIDR range than the ERP in the transit VPC.
2. B. Ensure that the security groups associated with the VM allow traffic to and from the desired resources.
3. C. Verify that the route table associated with the User VPC has appropriate routes to the Transit VPC.
4. D. Check that the network ACLs for the NO-NAT subnet are not blocking the necessary traffic.

Correct Answer: A
In this scenario, the issue arises from overlapping IP address ranges between the Transit VPC and the User VPC. Here??s a detailed breakdown:

✑ Communication Issue:
✑ Resolution:
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.
