NCSE-CORE EXAM QUESTIONS AND
ANSWERS 100% CORRECT
Which tool could be used to perform a sizing discovery in a general server virtualization
environment running both VMware ESXi and Nutanix AHV? - ANSWER-RVTools
Collector - ANSWER-A historical and point-in-time performance capture technology
which collects configuration and performance data of servers and its components
A customer is evaluating Nutanix to replace their existing 200TB filer. The filer is used to
store archived images. To achieve maximum storage density. RF2 and Erasure Coding
are proposed. What is the minimum number of nodes required to support the maximum
Erasure Coding stripe size of 4/1 (data/parity)? - ANSWER-6 nodes
By default, Nutanix clusters have what redundancy factor? - ANSWER-RF2
What are the redundancy factor 3 requirements? - ANSWER-Min 5 Nodes in cluster,
CVM with 32 GB of RAM configured
What are the redundancy factor 2 requirements? - ANSWER-Min 2 nodes in cluster,
CVM with 24 GB of RAM configured
Cassandra - ANSWER-Key Role: distributed metadata store. Stores and manages all of
the cluster metadata in a distributed ring-like manner
Zookeeper - ANSWER-Key Role: Cluster configuration manager. Stores all the cluster
configuration including hosts, IPs, states, etc. The service runs on three nodes in a
cluster, one of which is elected leader.
When reviewing Nutanix cluster upgrades. a customer engineer is concerned that their
VM will be forced to repeatedly migrate between nodes. Which Nutanix feature allows
VMs to remain on a host during an AOS upgrade? - ANSWER-CVM Autopathing
A healthcare prospect looking to refresh their infrastructure with Nutanix has an initiative
to migrate 5 Petabytes of unstructured, archived patient dat a. Which Nutanix product
should be the focus of the discussion? - ANSWER-Objects
In the event of a primary datacenter failure. a customer wants to power on virtual
machines in a secondary datacenter with an RPO and RTO of no more than 15
minutes. Upon further discussions with the customer. the systems engineer (SE) finds
that round trip latency between the 2 sites ca reach up to 6ms Which Nutanix feature
should the SE recommend? - ANSWER-NearSync
, Near Sync - ANSWER-Leverages Lightweight Snapshots that are snapshots of the
metadata. Recovery points can be 1-15 minutes apart.
Asynchronous Replication - ANSWER-Can be configured by backing up a group of
entities (VMs and volume groups) locally to the Nutanix cluster and optionally
configuring replication to one or more remote sites. Only schedules with RPO >= 60
minutes can be configured in this mode.
A prospective customer has a requirement for Data-at-Rest-Encryption for all their data
Which two license options are available to address this requirement? (Choose two) -
ANSWER-Ultimate & Pro with Encryption SKU
A System engineer (SE) is gathering requirements to size a hybrid cluster to replace a
prospect's existing IT test and development environment. The prospective customer has
indicated the cluster contains no business critical applications and has provided the
aggregate
vCPU and RAM requirements of the existing cluster.
Which two additional items does the SE require to size the cluster?(Choose two) -
ANSWER-Working Data Set and Storage Capacity
A prospective customer is evaluating solutions to support a project. The systems
engineer proposes a hybrid model as recommended by Sizer. The prospect is
concerned about the performance of a hybrid configuration and is evaluating an all flash
array.
Which two Nutanix features should be discussed to address the concerns of the
prospective customer? (Choose two - ANSWER-AHV Turbo Mode and Automatic Data
Tiering
An HA event occurs, which causes a SQL virtual machine to restart on a different
node.
What impact will this action have on Data Locality? - ANSWER-VM data will remain as
originally written and reads will occur across the network.
A prospective customer uses both Oracle and Microsoft products for critical
applications. The prospect. prefers an all flash array over HCI, because they have made
a recent, significant investment in physical servers for their Oracle environment to save
on licensing costs. Which feature should be discussed to address this objection? -
ANSWER-Volumes
Compared to a 3-tier architecture. Which two benefits does Nutanix bring to an
organization? (Choose two.) - ANSWER-Elimination of siloed storage with file, block,
and object storage in a single platform.
Ability to avoid generational infrastructure silos using modern life cycle management.
