NCP-CI-Azure Free Practice Test

Exhibit.

An administrator is trying to figure out why the NC2 cluster deployment in Azure failed. Which issue might be the cause?

1. A. The administrator has not specified a DNS server during deployment.
2. B. The selected bare metal node type is not supported in the deployment region.
3. C. DNS servers are not reachable from cluster management VNet.
4. D. The company does not have sufficient NCI/AOS licenses.

Correct Answer: B
✑ Error Message Analysis:The error message indicates that the node cannot boot successfully and will be replaced with a new node. This points towards an issue related to the specific node type or configuration.
✑ Bare Metal Node Support:One common cause for such deployment failures is selecting a bare metal node type that is not supported in the chosen deployment region. Azure has specific regions where certain node types are available, and attempting to use an unsupported node type in a region can result in provisioning failures.

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.

An administrator is planning an NC2 deployment in Azure and wants to connect the company??s on-premises datacenter to the cloud environment.
What connectivity solution should the administrator use to avoid traffic between the locations flowing over the public internet?

1. A. ExpressRoute
2. B. Site-to-Site VPN
3. C. Point-to-Site VPN
4. D. VTEP Gateways

Correct Answer: A
To connect the company's on-premises datacenter to the Azure cloud environment while avoiding traffic over the public internet, the administrator should use Azure ExpressRoute. ExpressRoute provides a private connection to Azure, offering more reliability, faster speeds, and lower latencies compared to typical internet connections. This service ensures that data traffic does not traverse the public internet, enhancing security and performance.References

Which entity should be contacted for cloud hardware support (EC2 instances, VPC, etc) related to NC2?

1. A. Nutanix
2. B. Public Cloud Vendor
3. C. Partner
4. D. Internal IT Operations team

Correct Answer: B
✑ 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:
✑ Conclusion: For cloud hardware-related support, the appropriate contact is the public cloud vendor.

Exhibit


Which action shouldthe administrator take to troubleshoot the error shown in the exhibit?

1. A. Check the NC2 organization permissions.
2. B. Check the Azure AD App registration Client Secret.
3. C. Check the Azure subnet delegation status.
4. D. Check the PC VNet is peered correctly.

Correct Answer: B
To troubleshoot the error shown in the exhibit where Azure credentials are not valid and the creation of the resource group failed, the administrator should:
✑ Verify that the Azure AD App registration has been correctly configured, especially
the Client Secret.
✑ Ensure that the Client Secret is valid, has not expired, and matches what has been entered in the configuration.
This step is crucial because an invalid or expired Client Secret would prevent the validation of Azure credentials and the creation of necessary resources.
