A consultant will be doing an install for an enterprise customer. The consultant has racked up, powered on, and connected their Foundation software to the new nodes. The Foundation VM is not discovering the hardware.

What should the consultant do to resolve this issue?

A.

Console to each node, reboot the node, go through BIOS to set an IPMI IP address, then run Foundation bare metal installation using IPMI IP addresses.

B.

Connect a crash cart to each node, log in to the pre-installed AHV hypervisor, run the IPMITool commands to set IPMI IP Address, subnet, and gateway for each node. Run a Foundation using the configured IPMI addresses that were just set.

C.

Collect the IPMI MAC addresses on the back of each node, run a bare metal Foundation using each MAC addresses.

D.

Connect a crash cart to each node, reboot the node, go through BIOS and set an IPMI IP address for each node. Using your Foundation VM, create a Phoenix boot ISO, then mount the ISO via Virtual Media connector from IPMI.

A customer wants to know the details of network validation testing.

Where can the consultant find this information?

A.

Handover checklist

B.

Test plan

C.

Operations Guides

D.

As-Built Guide

A consultant creates a four-node AHV cluster with two 1GbE (eth0, etc1) and two 10GbE (eth2, eth3) NICs per node. The 1GbE NICs will not be placed into service, but the customer wants the network to be preconfigured for their eventual use.

The consultant removes the 1GbE NIC from the default bond and creates a second bridge(br1), but is unable to add the 1GbE NIC using the below command:

manage_ovs –bridge_name br1 –interfaces 1g –bond_name br1-up update_uplinks

Which parameter is missing from this command?

A.

--bond_duplex full

B.

--require_link=false

C.

--interfaces eth0

D.

--bridge_duplex full

A consultant is onsite with a customer running Foundation VM (FVM) and discovers that there is no connectivity between the FVM and their laptop. The consultant verifies the following:

* The consultant’s laptop and Nutanix nodes are plugged into a flat switch.

* The laptop, switch and nodes are plugged into supported power supplies.

* The laptop network adapters and FVM are configured with their corresponding IP addresses.

What is the cause for the connectivity failure to the FVM?

A.

The switch is not plugged into the power supply.

B.

Desktop Firewall is blocking ping requests.

C.

Network cables are not connected.

D.

Laptop WiFi configured to use DHCP.

An administrator receives an alert in Prism indicating that interface eth2, on an AHV host is receiving many CRC errors. After togging into the problematic host, the following command is run to show the indicated output:

What is causing this issue?

A.

Incorrect link speeds on the switch

B.

The interface is incorrectly configured with Jumbo Frames

C.

A misconfigured bond

D.

A physical layer network problem

An administrator is planning to deploy a Nutanix cluster to support a few high-performance VMs. This deployment will have the following considerations:

• Individual VMs will likely generate network throughputs in the range of 90-100Mbps

• Due to the configuration of the VMs, it is unlikely that a node will host more than one or two of them at a time

• Individual VMs will communicate with only a few (one or two) remote hosts at a time

• Multicast will not be used in the environment

• The hosts are connected via two 1GbE network connections

How should the administrator configure the network bonds to meet this requirement while maintaining the simplest switch configuration?

A.

Configure bond0 as balance-sib

B.

Configure bond0 as active-backup

C.

Configure bond0 as balance-tcp

D.

Configure bond0 as balance-lacp

An administrator receives an error indicating that the CVMs in the cluster are not syncing to any NTP servers. An investigation of the issue finds:

• The NTP servers are configured in Prism

• The time on all CVMs is the same

• Both the CVMs and AHV hosts are configured for the UTC time zone

Which two steps can be taken to troubleshoot this issue? (Choose two.)

A.

Confirm that the NTP servers are reachable from the CVMs.

B.

Restart genesis on all CVMs.

C.

On a CVM. run the command a Hash ntpq -pn.

D.

Restart the chronos service on all CVMs.

While preparing for a new four-node cluster installation, the consultant has a Tech Review Call with the customer. The hardware is as follows:

* 4 nodes in 1 Block

* 8 x 10 GbE Ports

* 4 x 1 GbE IPMI Ports

* Adequate Ethernet ports are available

* Ethernet cables are correct and available

* Adequate rack space is available

Which remaining item must be confirmed as available onsite?

A.

Crash Cart

B.

Fibre Channel switches

C.

Redundant 208v power

D.

Redundant 110v power

A consultant and customer agree on a scope of services regarding the deployment of a new Nutanix cluster.

Which two products does this scope apply to? (Choose two.)

A.

Foundation

B.

Flow

C.

X-Ray

D.

Prism Central

A customer recently set up Async Replication between Site A and Site B. The customer wants to conduct a planned failover and clicks Activate on Site B.

The customer then runs the following command on Site A:

ncli pd deactivate_and__destroy_vms name=

What does this do to the customer environment?

A.

VMs get deleted from Site B. and the protection domain is now Active.

B.

VMs are powered off on Site A and must be manually powered on at Site B.

C.

VMs get deleted from Site A and the protection domain is no longer active.

D.

Customer must then manually power off VMs at Site A and power them on at Site B.
