An administrator is performing a set of routing checks and notes that Prism Central is running with 4 vCPUs and 21 GB RAM. The organization's environment is base 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?

Nutanix Leap an Nutanix Flow have been enable on Prism Central

Back

An administrator needs to relocate an AHV cluster to a new datacenter during a maintenance window. The cluster will use the same IPs in the new datacenter.

 

Which two steps should be taken to prepare for this task? (Choose two.)

Front

Stop all Nutanix files clusters

Shut down all user VMs in the cluster

Back

In a Nutanix cluster, a Protection Domain contains 50 entities that are replicated to a remote Single Node Replication Target.

The current schedule configuration is as follows:

Repeat every 6 hours

Local Retention Policy: 1

Remote Retention Policy: 8

Starting time 12 am

 

At 8 am on Monday, the administrator discovers that a protected VM is corrupted.  The latest good state was Sunday 2 pm. The administrator needs to maintain current protection.

 

Which strategy should the administrator use to meet these requirements?

Front

From the Remote site, restore the VM from the local snapshot by selecting the correct snapshot

Back

An administrator receives reports about a Nutanix environment. The investigation finds the following:

 

VMs are experiencing high latency

Each node is equipped with a single SSD, utilized at 95%

Each node is equipped with three HDDs, utilized at 40%

 

Why are the guest VMs experiencing high latency?

Front

All VM write operations are going to HDD

Back

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?

Front

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

Back

An administrator has a VM that consumes large amounts of storage and has the following characteristics:

 

Create large / sequential writes

Data must be kept for years

Data is normally only accessed at the end of the year to run report

 

The administrator decides to use Erasure Coding to save space.

 

Which feature should the administrator utilize to save space for this VM?

Front

Inline Compression

Back

Microsegmentation was recently enabled in a Nutanix environment. The administrator wants to leverage Prism Central to create a policy that will block all traffic, regardless of direction, between two groups of VMs identified by their category.

 

Which policy should be used to meet this requirement?

Front

An Isolation Environment Policy

 

Reference:

Back

An administrator needs to evaluate if the existing configuration of Protection Domains meets the specified corporate recovery policy for SQL Data. The corporate policy requires that all SQL Servers be recoverable at the DR site within 30 minutes, and must result in a maximum of 60 minutes of data loss. SQL data must be required.

 

The protection domain is configured as follows:

Application consistent snapshots are enabled

The SQL server VMs are assigned to the Protection Domain as their own Consistency Group

The Protection Domain schedule is configured as snapshots taken every 90 minutes from 7 am until 8 pm

 

What must be changed to meet the required policy?

Front

Revise the schedule to be 60 minutes

Back

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