An administrator needs to replace an aging SAN and move to a hyper-converged infrastructure. The existing environment consists of the following hosts that are connected to the SAN:

• 5xAIX hosts

• 3x Hyper-V hosts

• 9xESXi hosts

• 2x physical SQL Clusters (Windows Server 2012R2 hosts)

After deploying a Nutanix AHV cluster, which two actions should the administrator take to meet the requirements? (Choose two.)

A.

Deploy Volumes to support the AIX and SQL workloads.

B.

Migrate the ESXI workloads to AHV using Move.

C.

Deploy Files to support the AIX hosts.

D.

Migrate the ESXi and Hyper-V workloads using Move.

A company needs to replicate their VMs to a remote site and must have an RPO of less than 1 hour.

When creating a protection domain, what should an administrator do to meet this requirement?

A.

Enable Async Replication with an RPO of 60 minutes

B.

Enable Near-Sync Replication with an RPO of 15 minutes

C.

Enable Entity Sync on the designated VMs

D.

Enable Availability Zones and send the VM to multiple targets

An administrator has a custom backup application that requires a 2TB disk and runs in Windows. Throughput is considerably lower than expected.

The application was installed on a VM with the following configuration:

• Four vCPUs with one core/vCPU

• 4GB of Memory

• One 50GB vDisk for the Windows installation

• One 2TB vDisk for the application

What is the recommended configuration change to improve throughput?

A.

Increase the number of cores per vCPU

B.

Increase the vCPUs assigned to the VM

C.

Span the 2TB disk across four vDisks

D.

Add 4GB of memory to the VM

An administrator migrates a VM onto a new Nutanix cluster. After the migration, the administrator observes the following conditions:

• Cluster memory utilization: 64%

• Cluster CPU utilization: 19%

• Cluster storage utilization: 32%

• Average VM CPU utilization: 25%

• Average VM CPU ready%: 24%

• Average VM memory utilization: 60%

Which two changes should the administrator make to improve VM performance? (Choose two.)

A.

Add more memory to the VMs.

B.

Reduce the number of vCPUs assigned to VMs.

C.

Replace high core count CPUs with high clock rate CPUs. (also can be but is physical invas)

D.

Reduce the number of VMs on the hosts.

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 trying to correct high cluster IOPs and Cluster Controller Latency. Networking is the suspected issue.

Which networking parameters should be configured in the Nutanix cluster?

A.

Bond State and network latency

B.

Number of NICs connected and network latency.

C.

Number of NICs connected and frame size

D.

Number of NICs connected and bond state.

An administrator is currently using both 10g uplink with LACP and balance-tcp. A single VM should not be allowed to use more than a single 10G uplink, and both uplinks should be utilized.

Which two command should be used to configure the bond? (choose two)

A.

Ovs-vsctl set port br0-up bond_mode=balance-slb

B.

Ovs-vsctl set port br0-up bond_mode=balance-tcp

C.

Ovs-vsctl set port br0-up bond_mode=active-backup

D.

Ovs-vsctl set port br0-up other_config: bond-rebalance-interval=30000

An administrator is configuring software only. Data-at-Rest Encryption on their Nutanix cluster. They are planning to deploy a third-party key management server (KMS).

Where should this server be hosted?

A.

As a single VM on the Nutanix cluster

B.

On hardware external to the Nutanix duster

C.

As a clustered VM setup on the Nutanix cluster

D.

As a single VM deployed on the host that contains the Prism leader CVM

An administrator inherits a new Nutanix environment and logs in to a CVM to check the network configuration. The configuration is as follows:

Which action should the administrator take to improve network performance?

A.

Configure VLAN tagging both on br0 and br1 and their physical interfaces.

B.

Add eth0 and eth1 to the br0-up bond

C.

Configure balance-sib or balance-tcp mode for br0-up if switch configuration allows

D.

Remove one 10 Gbs interface from br0-up to make sure all 10 Gbs can be used.

An administrator of a Nutanix Enterprise Cloud has microsegmentation enabled and a firewall VM installed. The security team notifies the administrator that one of the VMs hosted in the environment has been exhibiting suspect network activity. The administrator wants to isolate the VM from the production network, but must still be able to access it to perform diagnostics.

What should the administrator do to meet the requirement?

A.

Disable the vNIC on the affected VM

B.

Quarantine the VM using the Forensic Method

C.

Create a firewall rule that blocks VM traffic but permits diagnostic access

D.

Create a security policy with a service chain directing that VMs traffic to the firewall VM
