A consultant deploys a Nutanix cluster with AOS and ESXi. The cluster is managed by a vCenter server.
After installation, what should the consultant do to ensure the cluster will support network segmentation?


A. Connect both CVM eth0 and eth2 interfaces to vSwitchNutanix.


B. Manually assign an IP address to the CVM eth2 interface.


C. Connect both CVM eth0 and eth2 interfaces to the assigned portgroups.


D. Add another vSwitch to the cluster.





C.
  Connect both CVM eth0 and eth2 interfaces to the assigned portgroups.

Explanation: After deploying a Nutanix cluster with AOS and ESXi managed by a vCenter server, the consultant should ensure that both CVM eth0 and eth2 interfaces are connected to the assigned portgroups on the standard or distributed switch. This setup allows for network segmentation and proper traffic isolation, which is crucial for maintaining network security and efficiency in a virtualized environment.

A consultant creates a Nutanix cluster using the 10.10.10.0/24 network and VLAN 10. The customer creates a VM network inside the Prism using VLAN 20. The customer starts to create VMs but is unable to ping the default gateway from these new systems.
What is causing the issue?


A. The CVM/hypervisor must be on an untagged VLAN.


B. The switch port is not set up as a trunk.


C. Only one VLAN is supported on AHV.


D. The CVM/hypervisor cannot use the same VLAN as guest VMs.





B.
  The switch port is not set up as a trunk.

Explanation: The issue of VMs not being able to ping the default gateway from a newly created VM network on VLAN 20, while the Nutanix cluster uses VLAN 10, most likely stems from the switch port configuration. For the VMs on VLAN 20 to communicate outside their local network, the switch port to which the Nutanix nodes are connected must be configured as a trunk. This configuration allows multiple VLANs to coexist on the same physical port and enables routing between them. Without the trunk setup, the VLAN 20 traffic is restricted and cannot reach the network beyond the switch, including the default gateway.

A consultant is unable to ping the CVM from the hypervisor using the external interface. The customer's network is configured with the 10.3.12.0/24 subnet without VLAN tagging. The CVM and hypervisor are using the same address space. What is causing this issue?


A. The 1GbE and 10GbE NICs have not been separated.


B. The default gateway is incorrect.


C. The switch is trunked without a native VLAN.


D. The CVM/hypervisor only communicates over 192.168.5.0/24.





B.
  The default gateway is incorrect.

A consultant needs to verify the make and model of the systems that will be imaged with Foundation. The consultant does not have the Bill of Materials (BOM) available to review. When should the consultant verify the make and model to prepare for the cluster deployment?


A. During the Foundation Process


B. While conducting the Tech Review Call


C. Upon arriving on-site


D. When reviewing the Statement of Work (SOW)





B.
  While conducting the Tech Review Call

B. Deploy a large 1-VM Prism Central instance.


C. Deploy a small 3-VM Prism Central instance.


D. Deploy a small 1-VM Prism Central instance.





A.

A consultant is reimaging a Nutanix cluster with a supported ISO, but Foundation returns an error that the media is not a supported ISO. Which two actions should the consultant take to resolve this issue? (Choose two.)


A. Restart the imaging process in Foundation.


B. Obtain the MD5 checksum of the ISO and confirm the MD5 checksum of ISO is listed.


C. Edit the whitelist file in Foundation.


D. Download and replace with the latest iso whitelist. json from the Support Portal.





B.
  Obtain the MD5 checksum of the ISO and confirm the MD5 checksum of ISO is listed.

D.
  Download and replace with the latest iso whitelist. json from the Support Portal.

A consultant is reviewing a customers Pre-delivery Questionnaire.
The customer wants to deploy their cluster with ESXi as the hypervisor with vSphere Distributed Switch. The customer will be using Cisco Nexus 9k as their switch choice In the kick-off call, it is confirmed that the customer has a business requirement to use LACP in their environment.
What should the consultant ensure that the customer configures on the port-channel interface before deployment?


A. show pore-channel


B. no lacp graceful-convergence


C. service unsupported-transceiver


D. no lacp suspend-individual





D.
  no lacp suspend-individual

An administrator is performing a set of routine checks and notes that Prism Central is running with 4 vCPUs and 21 GB RAM. The organizations environment is based on two Nutanix clusters with 170 VMs plus a Legacy vSphere infrastructure. No manual changes have been done on Prism Central VM.
Which configuration justifies the current Prism Central configuration?


A. Nutanix Move is running on Prism Central to import VMs from the Legacy Cluster.


B. Prism Central was installed for Large Deployment environments.


C. Prism Central is running on the legacy duster and requires more RAM.


D. Nutanix Leap and Nutanix Flow have been enabled on Prism Central





D.
  Nutanix Leap and Nutanix Flow have been enabled on Prism Central

A consultant is performing a Nutanix Cluster installation on Dell XC Core hardware. The consultant decides to use Foundation Portable for Mac to perform the installation. When the consultant arrives onsite, Foundation Portable is unable to locate the new nodes.

B. ~/data/logs/foundation.out


C. foundation.app/contents/resouces/log


D. ~/data/logs/foundation





B.
   ~/data/logs/foundation.out

A consultant is using the Foundation applet to create a cluster. During the process the consultant refreshes the progress bar web page and is concerned when nothing loads. What should the consultant do to verify that Foundation has completed successfully?


A. Return to the Foundation configuration page and start over.


B. Update Java on the Foundation VM.


C. Connect to any CVM IP address from a web browser.


D. Restart the Foundation process.
