An administrator is deploying several new application VMs to a Nutanix cluster. The application is very transactional with a 28/72 random, read/write ratio.

What should the administrator do?

An administrator receives a notification that storage in a Nutanix cluster is unavailable. The cluster consists of five nodes and is configured with a Fault-Tolerance level of 1 (FT-1).

Upon investigation, the administrator finds the following:

• All AHV hosts are powered on and the CVMs are running

• Nodes A, B, and C are connected to one top of rack switch

• Nodes D and E are connected to a second top of rack switch

• The cluster status command run on Node A shows that CVM services on nodes D and E are down

Which issue is causing the storage outage?

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?

Refer to the exhibit.

A Microsoft SQL 2016 deployment is shown in the exhibit. The administrator receives user reports that database queries take too long to return.

Which optimization should be made to this configuration to improve performance?

An administrator protected a DB VM running on a Nutanix cluster with NearSync Replication, which schedules to repeat every 15 minutes □ to a second site. The daily change rate is low. During nightly backups, the replication window is missed due to write volume.

Which two options describe the expected behavior? (Choose two.)

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?

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?

An administrator is configuring an All Flash cluster to support the following workloads:

• Full clone virtual desktops

• Hadoop

• Write heavy databases

Which three correct configuration options should the administrator use to meet the item requirements? (Choose three.)

For each procedure, indicate whether it is a correct or incorrect procedure that must be configured to meet the item requirements using the drop-down option.

A customer with a four-node RF2 cluster is adding application VMs to their system. After adding these VMs, the Prism dashboard shows 81% storage utilization.

What is the consequence of running the cluster at 81% storage utilization?

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?

An administrator has two clusters: Site A and Site B.

Async DR is configured between the clusters as follows:

• Site A is the Primary Site

• Site B is the Secondary inactive Site, no VMs running

• Site A is fully in Production

• Site B used as Backup/Disaster Recovery

The customer wants to perform a planned failover between the sites.

How should the administrator accomplish this?

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?

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?

An administrator is deploying a new application to a Nutanix Enterprise Cloud. The application requires a security to prevent unauthorized access. The application also uses many non-standard ports that are unique to it. Security should not be changed for existing applications.

What should the administrator do to meet these requirement?

A customer wants to run SAP HANA on a Nutanix cluster with the following characteristics:

• AHV nodes

• SAP HANA version 2

• Production database files

Which configuration should be recommended to the customer?

A customer has two mission-critical applications and needs to have them backed up to a remote location. The remote location is connected using a leased line and has an average latency of 7 ms.

Which Nutanix technology will provide the shortest RPO possible?

Refer to the exhibits.

An administrator has reported that a new VM is not performing well.

After analyzing the information presented in the exhibits, which option shows the best conclusion regarding this workload?

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?
