NCSE EXAM PREP QUESTIONS AND
ANSWERS RATED A.
A systems engineer is creating a configuration in Sizer for a customer that
is building an app for use as an eBooks repository the app requires the
following two workloads:
1. 50 generic web server VMs, each with 2 vCPUs on a 4:1 vCPU ratio, 8
GB of RAM, and 100GB of storage each
2. A fileserver workload with 80TB of usable storage available, which
contains mostly PDF's and pre- compressed data.
Any reduction in performance of the web servers must be avoided. After
entering the workload with default options, the Sizer outputs the
configuration shown in the exhibit.
Which adjustment does the systems engineer need to make to the scenario
to meet the performance requirements?
Switch to manual sizing and increase the RAM of the node configuration to
384 GB
A systems engineer is sizing a configuration for a cluster that needs to
tolerate up to 2 simultaneous disk failures across different nodes. What is
the minimum number of nodes required?
5
Which two items are considered by Sizer when calculating the required
cluster resources with only the Raw input workload type for a multi-VM
workload? (Choose two)
The required RAM for the CVM
The vCPU:pCore ratio applied to all VMs
,An online retailer currently support over 200 separate PostgreSQL
database instances, often with more than 10 copies of each individual
database. Their Database Administrators have scripted much of the
deployment process for creating dev/test copies, but their infrastructure
team struggles to keep up with storage capacity demands. Which Nutanix
product should the systems engineer position ?
Era
A customer is running AHV in their Nutanix cluster and wants to provide
their users with the ability to restore individual files from snapshots what
is the minimum level of licensing that must be applied to the Nutanix
cluster ?
Pro
With in RVtools output, which tab provides actual utilization information
on thick provisioned disk?
vPartition
A customer needs a tool packaged as a VM that uses realistic workloads
paired with real-world test scenarios for HCI environments. The goal is to
benchmark performance during typica! workflows and failure events.
Which Nutanix tool meets these requirements?
X-Ray
Which CVM service is responsible for providing storage to the hypervisor?
Stargate
A customer needs to image nodes that are either bare metal or require a
different hypervisor. Which Nutanix tool should be used?
Foundation
A customer's database administrator is concerned about restoring data
locality for their VMs after they migrate during an AHV upgrade. Which
feature that addresses the issue should the systems engineer highlight?
, AHV's built-in scheduler automatically restores data locality
A customer performs a 1-click, non-disruptive upgrade on a 3-node
Nutanix cluster. While the CVM on Node A is rebooting, a VM on Node A
overwrites an existing block of dat
a. How does Nutanix AOS ensure data integrity during the upgrade?
AOS writes two copies across the remaining nodes to maintain resiliency
A prospect customer's expected workload consists of the following: 110
vCPU 512GB RAM * 500TB Storage They need a solution to help decrease
storage costs. The majority of their storage requirements come from an
imaging application that stores scanned JPEG images. Which two Nutanix
capabilities should be leveraged? (Choose two.)
-Erasure Coding
-Storage-only Nodes
When creating a multi-cluster scenario in Sizer, what does the Summary
Failover Capacity indicator (N+0, N+1) display?
The indicator shows the best resiliency level of any cluster in the scenario
What is an important consideration when using RVTools output for sizing
a solution?
It is a point-in-time snapshot of the environment.
Compared to a 3-tier architecture, Which two benefits does Nutanix bring
to an organization? (Choose two.)
Elimination of siloed storage with file, block and object storage in a single
platform
Ability to avoid generational infrastructure silos using modem life cycle
management
An HA event occurs, which causes a SQL virtual machine to restart on a
different node. What impact will this cation have on Data Locality?
