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

An administrator needs to install prism central for their 2550 multi-cluster environment.
How should they deploy the application?

A. Deploy a large 3-VM Prism Central instance

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. Deploy a large 3-VM Prism Central instance
