Shrink the Volume Group that is associated with the Linux VM

B.

Unmount the Volume Group and then Remount the Volume Group

C.

Enable the unman operation on the Linux VM

D.

Run Defrag on the Linux VM

Question 6

Where should this server be hosted?

Options:

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

Question 7

Refer to the exhibit.

What is the purpose of eth2 on the CVMs?

Options:

A.

RDMA Network Segmentation

B.

iSCSI connectivity

C.

Remote site connectivity

D.

Network Segmentation

Question 8

After the migration, some SQL queries take longer to execute than prior to migration.

The following SQL best practices were applied while creating the SQL VM on Nutanix:

•8 vDisks per SQL server VM

•Database and Log files on separate vDisk

•2 TempDB database drives and 1 TempDB log drive

What should the administrator to do improve the SQL Server performance?

Options:

A.

Redistribute existing data by creating additional database file and enable autogrowth

B.

Create multiple TempDB data files and enable autogrowth

C.

Create multiple SQL log files and disable autogrowth

D.

Redistribute existing data by creating additional database files and disable autogrowth

Question 9

A customer has a four-node cluster and is using Volume Groups to provide storage services to a SQL cluster.

In the event of a CVM failure in the cluster, what is the expected IO path of the volume group’s iSCSI targets?

Options:

A.

vDisk directed at failure CVM are redirected to Data Services IP until CVM is reconnected

B.

vDisk directed to CVM that failed to disconnect and will not reconnect without manual intervention

C.

vDisk directed to failed CVM are redirected to another CVM and automatically reconnect

D.

vDisk directed at failed CVM will disconnect and reconnect when the failed CVM comes back online

Question 10

Refer to the exhibit.

Which action should the administrator take next?

Options:

A.

Configure the fqdn for the hosts indicated

B.

Troubleshoot the zookeeper server issue

C.

Re-run NCC specifying data_resiliency_check

D.

Options:

A.

Workloads are multi-threaded.

B.

VMs have one vCPU configured.

C.

VMs have multi-queue disabled.

D.

VMs have more than one vCPU.

Question 12

An administrator has a 32-node hybrid cluster with CPU, RAM and storage utilization of 80%. A database VM is configured with VM Flash.

What is causing this IO latency?

Options:

A.

Controller VM is experiencing high CPU ready time.

B.

Curator scans causes by ILM constantly moving data.

C.

VM Flash Mode reduces SSD tier capacity for VMs.

D.

Database VM is experiencing high CPU ready time.

Question 13

An administrator responsible for a VDI environment needs to investigate reports of slow logins. The administrator finds that increasing the number of vCPUs from 2 to 4 will reduce the login times.

What are two impacts on the cluster? (Choose two.)

Options:

A.

Increase CPU utilization%

B.

Increase CPU ready%
