NO.16 A consultant notices while assigning VLAN tags to hosts and CVMs in a running cluster, that Prism Element displays alerts indicating a node is down.
What should the consultant do to prevent these alerts?

Restart the Nutanix cluster.

Only change the Controller Virtual Machine VLANs.

Only change the hypervisor VLANs.

Stop the Nutanix cluster before changing VLANs.

NO.17 An administrator is deploying a three-tier application on a Nutanix Enterprise Cloud consisting of web, application, and database VMs. Traffic between theservers must be limited to specific services/ports. There is an application layer firewall VM deployed on one host in the cluster.
In which way should the administrator meet this requirement?

Create a network for each type of VM, and use policy-based routing to control the traffic flow

Configure a security policy and service chain redirecting the server traffic through the firewall

Separate the web. application and database VMs on to dedicated VLANs

Categorize the VMs in Prism Central and utilize Flow to set a security policy

NO.18 A customer has a Nutanix cluster with 10Gb connectivity via switch fabric extenders. The administrator receives NCC health check errors of latency greater than 200ms.
Which action should the administrator take to resolve the NCC errors?

Replace the switch fabric extenders with 10G line rate switches

Upgrade NCC and increase the CVM memory by 4Gb

Add 2 additional 10G uplinks from the switch fabric extenders per node

Upgrade NCC and increase the vCPU of the CVM

NO.19 An administrator is deploying Nutanix Files 3.5 and needs to configure the sizing of the FSVMs for an increased number of concurrent SMB connections over the default 750.
What should the administrator do?

Deploy the Files VMs.power down the three FSVMs. change the CPU and RAM via Prism, and then power the three FSVMs back up

During installation, click Customize on the File Server Installation screen, change the number of connections, and finish the installation

Complete the default installation change the CPU and RAM m Prism, and then log into the File Server dashboard and change the Filer Server Properties

During installation, input the correct number of connections in the File Server Installation screen and complete the installation

NO.20 Refer to the exhibit.

A Nutanix host is connected as shown in the exhibit with br0-up set to active/backup. Physical Switch 1 experiences a power outage causing br0-up to failover to using eth2. The CVM and host become inaccessible.
User VMs restart on other hosts in the cluster, which causes a disruption to those VMs.
Which configuration issue likely caused this outage?

Bridge br0-up should be configured to use balance-tcp rather than active/backup.

The CVM should have eth1 connected to the OVS.

The upstream port for eth2 is missing a VLAN.

The user VMs only have one NIC

NO.21 An administrator needs to make sure an RF3 cluster can survive a failure of two complete racks without negatively affecting performance. The current cluster configuration consists of the following:
* 30 All Flash Nodes: distributed 10 nodes per rack across three 42U racks
* Each node is configured with 20TB usable storage all flash (Cluster Total 600TB Usable)
* Current cluster utilization is 500TB storage
* Storage containers have Erasure Coding enabled
Which configuration changes should be made to make sure the cluster meets the requirements?

Expand the cluster to 50 nodes distributed evenly across 5 racks

Expand the cluster to 48 nodes distributed evenly across 6 racks

Expand the cluster to 60 nodes distributed evenly across 6 racks

Expand the cluster to 40 nodes distributed evenly across 5 racks

NO.22 A guest VM is reported to have poor storage performance. It has an I/O profile of 80%read. 20% write, and the HDDs form more than 50% of the read source.
What should an administrator do to resolve this issue?

Increase SSD capacity

Increase the OPLOG

Increase the write cache

Use HDDs with higher RPM

NO.23 A Nutanix cluster is deployed with the following configuration:
* Three four-node blocks (A, B, and C)
* All Flash Redundancy Factor 2
What is the effect of simultaneous disk failures on two nodes located in block A?

VMs are migrated off of the nodes with disk failures.

Each node with a failed disk is marked as degraded.

VM read and write operations continue normally.

VMs on the nodes with failed disks are unable to write data

NO.24 Refer to the exhibit.

An administrator is commissioning a Nutanix Enterprise Cloud. Once the user VMs have been deployed and are running, the administrator finds that VMs on the same host are able to communicate, but are unable to communicate between hosts.
What must be changed to enable full inter-VM communications?

Change the network the VMs are connected to

Change the spanning-tree port type on the switch

The VMs need to have static IPaddresses

Update the switch to specifically allow VLAN 15

NO.25 A customer has NearSync configured. When the administrator tries to restore a snapshot from 3 minutes ago, it is not available. The snapshots are happening at15-minute intervals instead of at the 5-minute configured interval. When the protection domain was initially set up, the snapshots were happening at the expected
5-minute interval.
What should the customer do to enable the snapshots to happen at the expected interval?

Utilize Metro Availability to meet this requirement

Change the protection domain to use Async DR

Fix a connectivity issue because the protection domain reverted to Async

Configure the protection domain to take snapshots on15-minute intervals

NO.26 During the cluster deployment, a consultant conducts operational tests on a vCenter-managed ESXi hypervisor.
As a part of tests, vCenter must place the host into maintenance mode, however, the task is stuck and the CVM is not shutting down automatically.
What should the consultant do to resolve the issue?

Shutdown the CVM using cvn_shutdown -P now.

Put the node into maintenance mode using

acli host.enter_maintenance_mode Hypervisor address.

Put the node into maintenance mode using ‘-/serviceability/bin/esx-shutdown-s cwn_.p_addr

Shutdown the CVM using shutdown -h now.
