(Choose two)

Which three configuration scenarios are valid for the deployment of Prism Central? (Choose three.)

An 8-node hybrid cluster is configured with a Fault Tolerance level of 2 (RF3). All nodes are identical. Which simultaneous failures will result in VM data being unavailable?

A prospective customer asks about failure handing. They have heard all HCI is the same and want to know what happens if 2 nodes fail within 1 hour of each other. if there is capacity in the cluster, how will this failure scenario be handled ?

A prospect uses VMware, Oracle and Microsoft products for their critical operations. The prospect prefers an all-flash array because they have significantly invested in servers for their oracle environment to save on licensing costs.

Which feature should be discussed to address this objection?

Refer to Exhibit.

When entering a Raw Input workload into Sizer, what amount of RAM should be used for the entire workload?

During a meeting with a prospect a storage administrator comments that they're currently using 16Gb Fibre Channel for their SAN and believes that 10Gb Ethernet can't provide adequate bandwidth or low latency.

As a followup to the meeting, which Nutanix Bible section would be most helpful in overcoming the storage administrator's objection?

A customer's current AHV cluster for mixed server workloads consists of 7 NX-3060-G6 nodes with intel Skylake processors spread across two blocks. Growing demand for resources requires the customer to order three additional NX-3060-G7 nodes with Intel Cascade Lake processors. Which supported approach allows the customer the most efficient use of their additional resources?

An administrator receive report that VDI desktop performance in an 8-node Nutanix VDI environment is poor. Opening applications takes between 1 and 2 minutes. When investigating the issue, the following conditions are found:

• Cluster memory utilization: 80%

• Cluster SSD utilization: 70%

• Average VM CPU wait time: 11 %

• CVM CPU utilization: 75%

Which action should be taken to improve VDI performance?

When using Nutanix Sizer, which solution does the Automatic sizing option provide?

A prospect is evaluating vSphere alternatives and has received FUD regarding AHV. The SE gives a demo and provides relevant case studies, but the prospect still requests a POC.

What additional option should the SE recommend to avoid a POC?

A systems engineer needs to size a new project that requires offsite backup using Veeam. The prospect requires an RPO of 24 hours, and the ability to restore from the past 7 days of backups. The prospect's data change rate is 1%. How should the SE configure the SE configure Sizer for this scenario? ????

A guest VM should be able to tolerate simultaneous failure of two nodes or drives.

What are the minimum requirements for the Nutanix cluster?

An SE is performing a sizing exercise for a large financial institution.

They plan to move 8000 VMs to Nutanix AHV manage those clusters using Prism Central.

Which sizing configuration should the SE use for each Prism Central VM?

An administrator has been alerted to a VM that has high I/O latency and wants to determine if there are any other factors, such as insufficient network or memory resources that correlate, as part of a troubleshooting process.

Which type of chart should the administrator create to allow all relevant data to be easily exported to CSV for later analysis?

Refer to the exhibit.

Based on the sizing scenario, what level of resiliency can be inferred about the configuration?

A prospect is evaluating solutions to support a project. The SE proposes a hybrid model as recommended by size in addition to nutanix, the prospect is evaluating an all flash storage array. The storage administrator is concerned about the performance the hybrid configuration and claims that the flash array is less expensive the it Director sees the benefits of Nutanix but needs to address the team's concerns.

Which two Nutanix features should be discussed to address the concems

of the storage administrator? (Choose two)

A prospect is experiencing disk performance issues in their database environment. The prospect's databases currently run on physical servers and an iSCSI SAN with spinning disks. Which two Nutanix features should an SE discuss with this prospect to address their disk performance issues? (Choose two)

A customer needs to expand an existing cluster to accommodate workloads. The workloads require 5TB of storage capacity (1.2TB of working set data), 64GB of memory, and 10 physical CPU cores. Their current cluster is configured as follows:

• 4x NX-3060-G5 nodes

• Each node is configured with 2x E5-2620v4 processors (8 Cores each), 128GB RAM, 2x 960GB SSDs, and 4x 2TB HDDs

• The cluster is configured as RF2 and is sized for N+1 availability

• Each CVM is configured with 32GB of memory

To maintain optimal metadata balance and data availability, which configuration should be recommended?

Write I/O that is deemed sequential will enter which component of the Distributed Storage Fabric first?

A prospect provides sizing details for a new application that will require 15TiB of usable storage. The prospect needs to plan for an additional 20% storage growth as part of the initial purchase. Including capacity to fully re-protect in the event of a node failure, which configuration provides minimal cost while meeting the capacity requirement?

In Files, how many FSVMs are deployed by default?

Refer to Exhibit.

An administrator increases the cluster RF to 3. The containers are not modified.

What will the new values in the data resiliency dashboard be for FAILURES TOLERABLE for the Zookeeper and Extent Groups components?

74. A VP of Applications at a prospective customer is working to transform IT from a cost, center to a business enabler. In order to address this initiative, the VP has identified the following areas for improvement: Increased time and expenses related to meeting business deliverables Missed market opportunity due to slow IT response time Shadow IT increases risk of security breaches and brand damage Unplanned spend on public cloud services (AWS) what two key benefits should the SE review to address the customer's challenges? (Choose two)
