NCP-CI-Azure Free Practice Test

An administrator manager a virtual desktop environment running on an NC2 cluster in Azure.
The desktop running on the cluster need to contact resources on-premises through the ExpressRoute that has been setup. The save on bandwidth from the on-premises environment to Azure, the administrator wants the desktops to access the internet through an Azure NAT Gateway.
Which co0nfigruation will best accomplish this task?

1. A. Set the default route of 0.0.0.0/0 for the Nutanix User VPC pointing to the external-No- NAT network.
2. B. Set the default route of 0.0.0.0/0 for the Nutanix User VPC pointing to the external-NAT networ
3. C. Set a route to the on-premises subnet for the Nutanix User VPC pointing to the external-No-NAT network.
4. D. Set the default route of 0.0.0.0/0 for the Nutanix User VPC pointing to the external-NAT networ
5. E. Set a route to the on-premises subnet for the Nutanix User VPC pointing to the external-NAT network.
6. F. Assign all desktops Floating IPs and use an external-NAT network in the transit VP
7. G. Set the default route of 0.0.0.0/0 for the Nutanix User VPC pointing to the external-NAT network.

Correct Answer: B
✑ Default Route for Internet Traffic:By setting the default route of 0.0.0.0/0 for the Nutanix User VPC pointing to the external-NAT network, all internet-bound traffic from the desktops will be routed through the Azure NAT Gateway, conserving bandwidth on the ExpressRoute connection.
✑ On-Premises Route:Setting a specific route to the on-premises subnet for the Nutanix User VPC pointing to the external-No-NAT network ensures that traffic destined for on-premises resources bypasses the NAT Gateway and utilizes the ExpressRoute connection, optimizing the use of network paths.

A company wants NC2 networking components to be created manually with the correct naming conversation. To achieve this the administrator manually creates the PC and Host VNets in Azure.
What additional Azure Network components must the administrator manually create?

1. A. NAT Gateway
2. B. Delegated Subnets, Flow Gateway Subnets, Transit VPC
3. C. NAT Gateways, Delegated Subnets, Flow Gateway Subnets, VNet Peers
4. D. internet Gateways, Private Endpoints, Flow Gateway Subnets, VNet Peers
5. E. Internet Gateway
6. F. Delegated Subnets, Flow Gateway Subnets, VNet Peers

Correct Answer: B
✑ NAT Gateways:Necessary for providing outbound internet access to resources in the private subnet. It ensures that the virtual network can communicate with external services securely.
✑ Delegated Subnets:Required for deploying specific Azure services within the virtual network, allowing controlled access and management of the resources within these subnets.
✑ Flow Gateway Subnets:These subnets are used for managing traffic flow within the network, ensuring efficient routing and connectivity between different parts of the NC2 infrastructure.
✑ VNet Peers:Establish connections between different virtual networks within Azure, enabling seamless communication and resource sharing across various parts of the NC2 deployment.

Which statement best describes south bound traffic to a Nutanix User VPC originating outside the BC2 cluster when using a no-NAT (routed path) having two or more Flow Gateways (FGW)?

1. A. A BGP gateway runs on the CVM of the bare-metal host
2. B. The BGP gateway advertises externally routable IP addresses to the Azure Route Server, with each active FGW external IP address the next hop.
3. C. A BGP gateway runs inside of Prism Centra
4. D. The BGP gateway advertises externally mutable IP addresses to the Azure Route Server, with each active FGW external IP address as the next hop.
5. E. A BGP gateway is deployed as Azure native VMs in the Prism Central VNe
6. F. The BGP gateway advertises externally routable IP addresses to the Prism Central, with each active FGW external IP address as the next hop.
7. G. A BGP gateway is deployed as Azure native VMs in the Prism Central VNe
8. H. The BGP gateway advertises externally routable IP addresses to the Azure Route Server, with each active FGW external IP address as the next hop.

Correct Answer: D
✑ BGP Gateway Deployment:The BGP gateway is deployed as Azure native VMs within the Prism Central VNet. This deployment ensures seamless integration with Azure's networking infrastructure.
✑ Route Advertisement:The BGP gateway advertises the externally routable IP addresses to the Azure Route Server. This setup allows for dynamic routing and efficient traffic management.
✑ Flow Gateways (FGW) as Next Hops:Each active Flow Gateway's external IP address is used as the next hop. This configuration ensures that southbound traffic is correctly routed to the appropriate Flow Gateway, providing efficient and reliable connectivity.

When selecting the NC2 subscription plan from the Nutanix billing portal, which options are available?

1. A. Pay-as-you-Go (payG), Bring your own License (BYOL)
2. B. Reserved instances, Cloud Provider Credits, Bring your own License (BYOL)
3. C. Reserved instances, Bring your own License (BYOL)
4. D. Pay-as-you-Go (PayG), Cloud Provider Credits, Bring you own License (BYOL)

Correct Answer: A
When selecting the NC2 subscription plan from the Nutanix billing portal, the available options are:
✑ Pay-as-you-Go (PayG):Allows you to pay for the services as you use them,
providing flexibility and avoiding upfront costs.
✑ Bring your own License (BYOL):Enables you to use your existing Nutanix licenses within the cloud environment, offering cost savings if you already have licenses.
These options provide flexibility in how you can manage and pay for your Nutanix cloud clusters.References

An administrator has setup a routed external network (No NAT) to use for workload running in NC2 clusters on Azure.
The applications are network intensive, so four gateways VMs have been deployed to meet the high demands. One application server on the NC2 clusters is sending traffic to an outside Azure service.
How many flow gateway VMs will be used to distribute the traffic?

1. A. All four Flow Gateway instances will be used based on the ECMP default route that points 3 the external subnets in the Nutanix Transit VPC, but only for sending traffi
2. B. Return traffic by use one Flow Gateway VM.
3. C. two flow gateway instances will be used based on limitations from using MAC addresses to redistribute traffic.
4. D. Only one Flow Gateway instance will be used per source application running on NC2.
5. E. All four Flow Gateway instances will be used based on the ECMP default route that points to the external subnets in the Nutanix Transit VPC for sending and receiving traffic.

Correct Answer: D
✑ Equal-Cost Multi-Path (ECMP) Routing:ECMP allows multiple gateways to be used simultaneously for load balancing traffic across multiple paths. In this scenario, ECMP is configured to point to the external subnets in the Nutanix Transit VPC.
✑ Traffic Distribution:All four Flow Gateway instances will be used to distribute the outgoing traffic from the application server based on the ECMP default route configuration. This ensures efficient load balancing and utilization of all available gateway resources.
✑ Bidirectional Traffic:Both sending and receiving traffic will utilize all four Flow Gateway instances, ensuring high availability and performance for network- intensive applications.
