Nutanix NCS-Core Practice Questions

Which two components must be identified to validate that software compatibility requirements are met for Nutanix Cluster Installation? (Choose two.)

A. Guest OS

B. AOS

C. Firmware

D. Hypervisor

Refer to the exhibit.

A consultant is installing AOS 5.10 and ESXi 6.5 on three nodes. During the Foundation process, ESXi 6.5 is not available as one of the choices for hypervisor.
Which solution should the consultant use?

A. Upload ESXi image to /home/Nutanix/foundation/nos/hypervisor/esx.

B. Restart Foundation VM and refresh Foundation page.

C. Update the Foundation whitelist from the support portal.

D. Upload ESXi image to /home/Nutanix/foundation/isos/hypervisor/esx.

Refer to Exhibit:

A customer is preparing to expand a cluster with a consultant. The production cluster is comprised of one NX-3460-G7 and two NX-8235 G8 blocks. The running AOS version is 5.20.4.6 and Hypervisor version is ESXi 6.7 U3b. vCenter is also running a 6.7 version.
One NX-3235-G9 block will be added to that cluster (ESXI-NUTA-09 and ESXI-NUTA-10).
The consultant has verified Nutanix documentation and customer’s As-Built guide:
•NX-3060-G7 and NX-8035-G8 are hybrid HCI nodes
•ESXi 6.7 U3b is unsupported for the new G9 hardware model
•AOS 5.20.X and ESXi 6 X are end of support
•NX-3060-G7 and NX-8035-G8 hypervisors can be upgraded to the latest ESXi supported version
What actions should be taken before beginning the cluster expansion?

A. Upgrade vCenter, AOS and ESXi to supported and recommended versions.

B. Upgrade only AOS and ESXi to supported and recommended versions.

C. Replace all HDDs with SSDs on the Production cluster.

D. Prepare Foundation and the whitelist. json file to deploy ESXi 6.7 U3b on the new nodes.

Refer to the exhibits.
An administrator has reported that a new VM is not performing well.

A. VM is CPU constrained since the hypervisor cannot provide the required resources.

B. VM is CPU constrained because more CPU needs to be added to the VM.

C. VM is Storage constrained, because the workload is waiting for storage access.

D. VM is not CPU constrained, because the VM is not running, a multithreaded application.

A consultant is conducting a vSphere cluster deployment. As a part of operational tests, a vMotion operation is performed on a test VM, but fails with following error message:
The VMotion failed because the ESX hosts were not able to connect over the VMotion network. Please check your VMotion network settings and physical network configuration.
VMotion [184329483:1276605211167987] failed to create connection with remote host <10.10.16.14>: The ESX hosts failed to connect over the VMotion network Migration [184329483:1276605211167987] failed to connect to remote host <10.10.16.14>: Timeout What issue could prevent the vMotion operation from completing successfully?

A. The vmknic is configured with a conflicting IP address.

B. NIOC is enabled and vMotion traffic is configured with Share value SO.

C. Foundation service prevents connectivity between the source and the destination TCP port 8000.

D. The vSS is configured with Route based on originating virtual port.

A.   The vmknic is configured with a conflicting IP address.

Explanation: The failure of the vMotion operation indicated by the error message could most plausibly be caused by: A. The vmknic (VMkernel network interface card) configured with a conflicting IP address. This conflict can prevent the ESXi hosts from establishing a connection over the VMotion network, as each host must have a unique IP address on the VMotion network to facilitate proper migration communications. Option B, involving NIOC settings, and option D, involving vSS configuration, could influence performance but are less likely to cause a complete failure to connect. Option C, related to the Foundation service, is not relevant to vMotion networking issues directly. References: VMware vSphere Networking Documentation, Nutanix Integration with VMware Environments.
