Question 1Nutanix Cloud Platform Fundamentals

Which Nutanix component runs on each host and provides the distributed storage layer that pools local disks into a single namespace?

  1. Cluster Virtual IP
  2. Foundation VM
  3. Controller VM (CVM) Correct answer.
  4. Prism Central

Explanation

The Controller VM runs on every node in the cluster and owns that node's local storage devices, presenting them through the distributed storage fabric as one pool. Prism Central and Foundation are management and imaging tools, not the per-host storage controller.

Question 2Nutanix Cloud Platform Fundamentals

What is the primary role of Prism Element in a Nutanix cluster?

  1. It is the replication engine between sites
  2. It replaces the hypervisor on each node
  3. It provides per-cluster management of VMs, storage, and health Correct answer.
  4. It is the licensing portal for the cluster

Explanation

Prism Element is the built-in management interface that runs in the cluster and handles VM operations, storage configuration, alerts, and health for that cluster. Higher-level multi-cluster management is handled by Prism Central.

Question 3Nutanix Cloud Platform Fundamentals

A cluster administrator needs a single pane of glass to manage several Nutanix clusters and to enable features such as categories-based policy. Which component should be deployed?

  1. Nutanix Calm
  2. Prism Element
  3. Nutanix Move
  4. Prism Central Correct answer.

Explanation

Prism Central is the multi-cluster management plane and is required for policy-driven capabilities that span clusters, such as categories and many advanced services. Prism Element manages only its own cluster and does not provide cross-cluster policy.

Question 4Nutanix Cloud Platform Fundamentals

Which Nutanix feature caches data from a shared read-only base vDisk at multiple Controller VMs to improve read performance?

  1. Shadow clones Correct answer.
  2. Deduplication
  3. Data locality
  4. Erasure coding

Explanation

Shadow clones allow Controller VMs to cache data from a commonly accessed read-only base vDisk locally. This lets VMs on different hosts read the shared base data through their local CVMs, reducing repeated remote reads of the same shared data.

Question 5Nutanix Cloud Platform Fundamentals

An administrator wants to reduce storage capacity consumption by striping data and parity across nodes instead of keeping full replicas. Which capability should be enabled?

  1. Compression
  2. Deduplication
  3. Erasure coding Correct answer.
  4. Capacity tiering

Explanation

Erasure coding stores data with parity stripes across the cluster, lowering the capacity cost compared with maintaining full replicas. Compression and deduplication reduce the size of stored data but do not change the replica/parity scheme.

Question 6Nutanix Cloud Platform Fundamentals

Which Nutanix networking construct allows a VM to keep its IP address when it is migrated between hosts or clusters without reconfiguring the guest OS?

  1. NAT network
  2. Bridged network with static MAC pinning
  3. Host-only network
  4. Virtual switch with VLAN-backed networks Correct answer.

Explanation

Nutanix AHV uses virtual switches with VLAN-backed networks so a VM's network identity follows it across hosts and clusters. The guest keeps its IP because the virtual network definition moves with the VM rather than being bound to physical host wiring.

Question 7Nutanix Cloud Platform Fundamentals

A Nutanix cluster uses RF3. How many copies of each data block are maintained?

  1. Two
  2. One
  3. Four
  4. Three Correct answer.

Explanation

Replication factor 3 means the distributed storage fabric keeps three copies of each block on separate nodes. This tolerates the loss of two nodes while preserving data availability.

Question 8Nutanix Cloud Platform Fundamentals

Which Nutanix service provides application-consistent snapshots and backups by coordinating with the guest operating system?

  1. Flow Network Security
  2. Prism Central
  3. Volume Groups
  4. Nutanix Guest Tools Correct answer.

Explanation

Nutanix Guest Tools installs agents in the guest that quiesce applications so snapshots are application-consistent. Without it, snapshots are crash-consistent and may not reflect in-flight application writes.

Question 9Nutanix Cloud Platform Fundamentals

Which Nutanix capability lets an administrator define security policy based on VM categories rather than IP addresses?

  1. Protection domains
  2. Flow Network Security Correct answer.
  3. Data-at-rest encryption
  4. Async replication

Explanation

Flow Network Security applies distributed firewall rules using categories, so policy follows VMs as their addresses change. Encryption and protection domains address confidentiality and backup respectively, not identity-based segmentation.

Question 10Nutanix Cloud Platform Fundamentals

What does a Nutanix protection domain primarily define?

  1. A licensing entitlement for advanced features
  2. A set of VMs and a snapshot/replication schedule for consistency groups Correct answer.
  3. A firewall rule set for a category of VMs
  4. A storage pool of physical disks

Explanation

A protection domain groups VMs so they can be snapshotted and replicated together on a defined schedule, preserving consistency across the group. It is a data protection construct, not a security or licensing one.

Question 11Nutanix Cloud Platform Fundamentals

An administrator needs to migrate running VMs from a VMware environment to Nutanix AHV with minimal downtime. Which tool is designed for this?

  1. Nutanix Foundation
  2. Nutanix Move Correct answer.
  3. Nutanix Era
  4. Nutanix Files

Explanation

Nutanix Move performs live migrations of VMs from other hypervisors to AHV, handling the cutover with minimal service interruption. Foundation images clusters, Files provides file services, and Era manages database lifecycle.

Question 12Nutanix Cloud Platform Fundamentals

Which Nutanix product provides a scale-out SMB and NFS file service on top of the cluster?

  1. Nutanix Objects
  2. Nutanix Flow
  3. Nutanix Volumes
  4. Nutanix Files Correct answer.

Explanation

Nutanix Files delivers SMB and NFS shares backed by the distributed storage fabric, scaling out across the cluster. Volumes provides block access, Objects provides S3-compatible storage, and Flow provides networking and security.

Question 13Nutanix Cloud Platform Fundamentals

Which Nutanix service provides S3-compatible object storage that can span clusters?

  1. Nutanix Objects Correct answer.
  2. Nutanix Calm
  3. Nutanix Volumes
  4. Nutanix Files

Explanation

Nutanix Objects is a software-defined object store with an S3-compatible API that can be deployed across clusters and sites. Files is file-based, Volumes is block-based, and Calm is application automation.

Question 14Nutanix Cloud Platform Fundamentals

A cluster has RF2 configured. What is the minimum number of node failures the cluster can tolerate while keeping data available?

  1. Zero
  2. Three
  3. Two
  4. One Correct answer.

Explanation

With two copies of each block on separate nodes, the loss of one node leaves one copy available, so one failure is tolerated. Tolerating two failures would require RF3.

Question 15Nutanix Cloud Platform Fundamentals

Which statement best describes how AHV handles storage for a VM's virtual disk?

  1. The disk is stored as a raw file on the local filesystem of the host running the VM
  2. The disk is stored only on an external SAN LUN
  3. The disk is stored in the guest OS as a sparse file
  4. The disk is stored as vDisk extents managed by the distributed storage fabric Correct answer.

Explanation

AHV stores VM disks as vDisks whose extents are placed and replicated by the distributed storage fabric across nodes. The VM is not tied to a single host's local filesystem or to an external SAN.

Question 16Nutanix Cloud Platform Fundamentals

What is the purpose of the cluster virtual IP in a Nutanix cluster?

  1. It is the address assigned to the guest VM network
  2. It is the address used for replication traffic between sites
  3. It is the address used for live migration of VMs
  4. It provides a single management address that remains reachable if a node fails Correct answer.

Explanation

The cluster virtual IP is a management address that floats to a surviving node so administrators can always reach Prism Element. It is not used for VM data traffic or replication.

Question 17Nutanix Cloud Platform Fundamentals

An administrator wants to tier cold data to a cheaper storage medium while keeping hot data on fast local disks. Which Nutanix capability addresses this?

  1. Compression
  2. Storage tiering with capacity tier Correct answer.
  3. Deduplication
  4. Erasure coding

Explanation

Storage tiering moves less-frequently accessed data to the capacity tier while keeping active data on the faster hot tier. Erasure coding, deduplication, and compression reduce capacity overhead but do not move data between media tiers.

Question 18Nutanix Cloud Platform Fundamentals

Which Nutanix capability provides application lifecycle automation using blueprints?

  1. Nutanix Move
  2. Nutanix Calm Correct answer.
  3. Nutanix Flow
  4. Nutanix Files

Explanation

Nutanix Calm uses blueprints to model, deploy, and manage multi-tier applications across environments. Flow handles security, Move handles migration, and Files handles file storage.

Question 19Nutanix Cloud Platform Fundamentals

What is the primary function of Nutanix Foundation?

  1. Providing S3-compatible object storage
  2. Imaging and deploying Nutanix software onto bare-metal nodes Correct answer.
  3. Backing up VMs to a remote site
  4. Enforcing microsegmentation policy

Explanation

Foundation discovers nodes and images them with the Nutanix software stack to bring up or expand a cluster. Backup, object storage, and security policy are handled by other services.

Question 20Nutanix Cloud Platform Fundamentals

A VM's virtual disk is configured with a replication factor of 2 in a cluster that has five nodes. Which outcome follows if a single node holding one copy fails?

  1. The remaining copy serves reads and the fabric re-replicates to restore RF2 Correct answer.
  2. The cluster drops to RF1 permanently
  3. The VM immediately loses access to its disk
  4. The disk is automatically converted to erasure coding

Explanation

With two copies on separate nodes, a single node failure leaves one copy available, so the VM keeps running while the fabric creates a new replica to restore the configured factor. The cluster does not permanently reduce redundancy.

Question 21Nutanix Cloud Platform Fundamentals

Which statement accurately distinguishes Prism Central from Prism Element?

  1. Prism Central replaces the distributed storage fabric, while Prism Element provides it
  2. Prism Central runs only on external hardware, while Prism Element runs only in the cloud
  3. Prism Element manages multiple clusters, while Prism Central manages a single node
  4. Prism Central manages multiple clusters and enables cross-cluster policy, while Prism Element manages a single cluster Correct answer.

Explanation

Prism Element is the per-cluster management interface, and Prism Central aggregates many clusters to provide centralized management and policy features such as categories. Neither replaces the storage fabric, which is provided by the CVMs.

Question 22Nutanix Cloud Platform Fundamentals

An administrator enables deduplication and compression on a container holding many similar VM clones. What is the most likely effect?

  1. Elimination of the need for replication
  2. Automatic conversion of the container to RF1
  3. Reduced physical capacity consumption with some increase in CPU overhead Correct answer.
  4. Loss of application consistency for snapshots

Explanation

Deduplication removes duplicate blocks and compression shrinks stored blocks, lowering physical usage at the cost of some processing overhead. These features do not change replication factor or snapshot consistency behavior.

Question 23Nutanix Cloud Platform Fundamentals

A cluster must survive the simultaneous loss of two nodes while keeping all data available. Which configuration satisfies this requirement?

  1. Replication factor 2
  2. Replication factor 3 Correct answer.
  3. Erasure coding with a single parity stripe
  4. Deduplication enabled on all containers

Explanation

RF3 keeps three copies on separate nodes, so two node failures still leave one copy available. RF2 tolerates only one failure, and deduplication does not add redundancy.

Question 24Nutanix Cloud Platform Fundamentals

Which Nutanix feature allows a VM to be cloned rapidly by referencing shared base data instead of copying full disks?

  1. Shadow clones Correct answer.
  2. Protection domains
  3. Capacity tiering
  4. Erasure coding

Explanation

Shadow clones create new VMs that reference existing base disk data, so cloning is fast and consumes little additional space until changes occur. Erasure coding, protection domains, and tiering serve different purposes.

Question 25Nutanix Cloud Platform Fundamentals

Which statement best explains why Nutanix can continue serving I/O when a CVM on one node becomes unavailable?

  1. The hypervisor takes over storage serving on the failed node
  2. The cluster VIP redirects storage traffic to an external SAN
  3. Other CVMs in the cluster can serve the affected data because replicas reside on separate nodes Correct answer.
  4. Prism Central temporarily becomes the storage controller

Explanation

Because each block has replicas on separate nodes, other CVMs can satisfy I/O for the affected data while the cluster heals. The hypervisor does not become a storage controller, and no external SAN is required.

Question 26Nutanix Cloud Platform Fundamentals

Which component of the Nutanix Cloud Platform runs on every node and serves storage I/O to the hypervisor?

  1. Controller VM (CVM) Correct answer.
  2. Foundation VM
  3. Cluster virtual IP
  4. Prism Central

Explanation

Each node runs a Controller VM that owns the local disks and presents them as a distributed storage pool to the hypervisor. The hypervisor's storage traffic is redirected to a CVM rather than to a local disk controller. Prism Central, Foundation, and the cluster VIP are management or deployment components, not data-path storage services.

Question 27Nutanix Cloud Platform Fundamentals

An administrator wants a single pane of glass to manage several Nutanix clusters, including VM provisioning, categories, and image placement across them. Which component should be deployed?

  1. Nutanix Move
  2. Prism Central Correct answer.
  3. Nutanix Files
  4. Prism Element

Explanation

Prism Central is the multi-cluster management plane that aggregates registered Prism Element instances and adds features such as categories, images, and centralized VM management. Prism Element manages only its own cluster, while Move and Files are workload-migration and file-services products rather than management consoles.

Question 28Nutanix Cloud Platform Fundamentals

In Nutanix AHV, what is the role of a virtual network (network configuration) created in Prism Element?

  1. It binds the cluster to an external LDAP directory
  2. It assigns replication factor to each virtual disk
  3. It schedules snapshots for the guest operating system
  4. It defines a VLAN-backed L2 segment to which VM NICs are attached Correct answer.

Explanation

AHV virtual networks map to a bridge and optionally a VLAN ID, providing the L2 segment that VM NICs connect to. Replication factor is a storage policy, snapshot scheduling is a protection policy, and directory integration is an authentication setting, so none of those are functions of a virtual network.

Question 29Nutanix Cloud Platform Fundamentals

Which Nutanix capability lets an administrator apply a storage policy such as replication factor and compression to a VM at provisioning time without choosing a specific container?

  1. Storage policies applied through Prism Central Correct answer.
  2. Volume groups mapped over iSCSI
  3. Protection domains defined per container
  4. Host affinity rules in AHV

Explanation

Storage policies abstract container-level settings; Prism Central lets you define policies that specify replication factor, compression, deduplication, and encryption, then attach them to VMs. Protection domains govern snapshot and replication schedules, volume groups expose block storage over iSCSI, and affinity rules control VM placement.

Question 30Nutanix Cloud Platform Fundamentals

An administrator must restore a single file from a Nutanix guest VM snapshot without restoring the whole VM. Which approach is appropriate?

  1. Change the VM's storage policy to RF3 and reboot
  2. Detach the VM's NIC and reattach it
  3. Run Foundation to reimage the host holding the VM
  4. Mount the snapshot disk and browse its file system from a helper VM Correct answer.

Explanation

A VM disk snapshot can be cloned or mounted as a disk to another VM, letting the administrator browse the file system and copy out the needed file. Storage policy changes, reimaging, and NIC operations do not expose snapshot contents for file-level recovery.

Question 31Nutanix Cloud Platform Fundamentals

A Nutanix cluster must keep serving I/O if one CVM is rebooted for maintenance. Which design characteristic makes this possible?

  1. Each VM's disk is pinned to a single node's local disk
  2. Data is distributed across CVMs, and peers serve requests for the unavailable CVM Correct answer.
  3. Prism Central takes over storage I/O for the affected node
  4. The hypervisor caches all writes locally until the CVM returns

Explanation

Nutanix is a distributed system: metadata and data are spread across nodes, and when one CVM is down the remaining CVMs continue to serve I/O for the affected extents. There is no hypervisor-wide write cache that substitutes for a CVM, Prism Central is not in the data path, and disks are not pinned to a single node.

Question 32Nutanix Cloud Platform Fundamentals

An administrator needs to replicate a protection domain to a remote Nutanix cluster for disaster recovery. What must exist between the two clusters before the schedule can run?

  1. An identical number of nodes in both clusters
  2. A remote site configured with the target cluster's address and credentials Correct answer.
  3. A shared VLAN stretched between both clusters
  4. A single Prism Central instance managing only the source

Explanation

Protection domain replication requires the source cluster to be configured with a remote site that identifies the target cluster and its credentials. Stretched VLANs, equal node counts, and a Prism Central managing only the source are not prerequisites for asynchronous replication.

Question 33Nutanix Cloud Platform Fundamentals

What does enabling erasure coding on a Nutanix container change about how data is stored?

  1. It encrypts data at rest using a cluster-wide key
  2. It stripes data and parity across nodes to reduce capacity overhead compared with replica copies Correct answer.
  3. It moves cold data to an external object store
  4. It converts the container to an SMB share

Explanation

Erasure coding stores data as stripes with parity blocks across nodes, which lowers the capacity cost relative to keeping full replicas. Encryption, tiering to external object storage, and protocol presentation are separate features and are not effects of erasure coding.

Question 34Nutanix Cloud Platform Fundamentals

Which Nutanix component provides the REST API endpoint that automation scripts use to manage VMs across multiple clusters?

  1. The Foundation service
  2. The AHV host agent
  3. A CVM's local iSCSI target
  4. Prism Central Correct answer.

Explanation

Prism Central exposes a REST API that covers multi-cluster operations such as VM lifecycle and category management. An iSCSI target serves block storage, the host agent runs on the hypervisor host, and Foundation handles imaging, so none of them provide the multi-cluster management API.

Question 35Nutanix Cloud Platform Fundamentals

An administrator wants VMs to be placed only on hosts in a specific rack for latency reasons. Which AHV mechanism should be used?

  1. Protection domain with a one-hour schedule
  2. Erasure coding on the container
  3. Affinity policy scoped to the hosts in that rack Correct answer.
  4. Storage policy with RF3

Explanation

AHV affinity policies constrain VM placement to a set of hosts, which can be grouped by rack or other attribute. Storage policies, protection domains, and erasure coding affect data protection or efficiency and do not control where a VM runs.

Question 36Nutanix Cloud Platform Fundamentals

Which statement describes how Nutanix handles a VM's data locality when the VM is migrated with live migration to another host?

  1. The destination host mounts the source host's disk through NFS
  2. The VM's disks must be copied in full to the destination host's local disk first
  3. The VM loses its storage policy and reverts to RF1
  4. The VM continues to access its data through the distributed storage layer regardless of host Correct answer.

Explanation

Because storage is distributed and accessed through CVMs, a migrated VM keeps its disks where they are and simply reaches them through the storage layer from its new host. No full disk copy, policy reset, or host-to-host NFS mount is involved.

Question 37Nutanix Cloud Platform Fundamentals

An administrator wants to apply the same security policy to every VM tagged as belonging to the finance application, including VMs created later. Which Nutanix feature supports this?

  1. Static IP-based firewall rules on each host
  2. A protection domain per VM
  3. Per-VM VLAN assignment in AHV
  4. Categories combined with a security policy in Prism Central Correct answer.

Explanation

Categories are key-value labels that can drive policy, and Prism Central security policies can match on categories so newly created VMs with the same category inherit the rules. IP-based rules, VLAN assignment, and protection domains do not provide category-driven, automatically applied policy.

Question 38Nutanix Cloud Platform Fundamentals

A cluster is configured with RF2 and erasure coding on a container. Which statement best describes the trade-off the administrator accepted?

  1. Synchronous replication to a remote site
  2. Lower capacity overhead than pure replication, with tolerance of fewer simultaneous failures for that data Correct answer.
  3. No redundancy for data in that container
  4. Higher capacity overhead than RF3 with tolerance of two node failures

Explanation

Erasure coding reduces the capacity cost compared with keeping full replicas, but its failure tolerance is generally lower than RF3 and depends on the coding scheme. It does not remove redundancy, and it is a local storage layout rather than remote synchronous replication.

Question 39Nutanix Cloud Platform Fundamentals

An administrator plans to expand a cluster by adding a node. Which statement about data rebalancing after the node joins is accurate?

  1. Rebalancing requires Prism Central to be licensed on the new node
  2. The cluster redistributes extents in the background while continuing to serve I/O Correct answer.
  3. The new node receives no data until an administrator runs a manual copy
  4. All VMs must be powered off until rebalancing completes

Explanation

When a node joins, the distributed storage layer rebalances extents across nodes in the background without taking the cluster offline. VMs do not need to be powered off, data placement is automatic rather than manually copied, and Prism Central licensing is not a condition for rebalancing.

Question 40Nutanix Cloud Platform Fundamentals

Which Nutanix feature allows an administrator to define a multi-step VM provisioning workflow with approvals that runs against Prism Central?

  1. Nutanix Flow
  2. Nutanix Calm Correct answer.
  3. Nutanix Era
  4. Nutanix Mine

Explanation

Nutanix Calm provides application lifecycle automation with blueprints and runbooks, including approval steps, executed against Prism Central. Mine handles backup integration, Era focuses on database lifecycle management, and Flow provides network security and microsegmentation.

Question 41Hyperconverged Infrastructure and Distributed Storage Concepts

In a hyperconverged infrastructure (HCI) cluster, what is the primary role of the distributed storage layer?

  1. It replaces the hypervisor by running virtual machines directly on the storage controller
  2. It aggregates local disks from each node into a single shared datastore presented to the hypervisor Correct answer.
  3. It centralizes all writes on a single controller node to guarantee ordering
  4. It provides a Fibre Channel fabric between nodes and external SAN arrays

Explanation

HCI collapses compute and storage into the same nodes, and the distributed storage layer pools each node's locally attached disks into one logical datastore that every host can access. This software-defined approach removes the need for a dedicated external SAN array.

Question 42Hyperconverged Infrastructure and Distributed Storage Concepts

Which statement best describes how data redundancy is typically achieved in a hyperconverged cluster using a replica-based scheme?

  1. Each write is written once and protected only by a nightly backup to tape
  2. Each write is synchronously copied to another node so a copy survives a host failure Correct answer.
  3. Parity is calculated across a single disk and stored on the same disk
  4. Data is mirrored only within the same physical disk using RAID 1

Explanation

Replica-based distributed storage writes each block to multiple nodes, and the write is acknowledged only after the required copies are durable. If one node fails, another node already holds a complete copy, so availability is preserved without rebuild from backup.

Question 43Hyperconverged Infrastructure and Distributed Storage Concepts

What does a storage policy with a "failures to tolerate" value of 2 mean for a virtual machine's data?

  1. The cluster can lose two independent components and still serve the data Correct answer.
  2. Two snapshots of the VM are retained at all times
  3. The VM can be migrated between two hosts at the same time
  4. The datastore is limited to two hosts in the cluster

Explanation

Failures to tolerate expresses the number of independent failures, such as host or disk-group losses, that the data can absorb while remaining available. A value of 2 generally implies three copies or equivalent erasure coding across separate failure domains.

Question 44Hyperconverged Infrastructure and Distributed Storage Concepts

Why does a hyperconverged cluster need a cluster-wide membership and quorum mechanism?

  1. To compress replication traffic between nodes
  2. To cache reads on the local SSD tier
  3. To prevent split-brain by ensuring only a majority partition can serve writes Correct answer.
  4. To assign IP addresses to virtual machines

Explanation

Quorum establishes which partition holds a majority of cluster members, so during a network partition only that side continues to accept writes. This avoids two isolated halves both modifying data and diverging, a condition known as split-brain.

Question 45Hyperconverged Infrastructure and Distributed Storage Concepts

What is the main purpose of a witness component in a two-node hyperconverged cluster?

  1. To act as the primary network gateway for the cluster
  2. To break ties for quorum when the two data nodes cannot communicate Correct answer.
  3. To provide additional CPU capacity during failover
  4. To store a full replica of all virtual machine data

Explanation

With only two data nodes, a network partition leaves neither side with a majority, so a lightweight witness hosted elsewhere casts the deciding vote. It holds metadata for arbitration rather than a full copy of the data.

Question 46Hyperconverged Infrastructure and Distributed Storage Concepts

In a distributed storage system, what distinguishes a rebuild from a resynchronization?

  1. A rebuild reconstructs lost redundancy on surviving components after a failure; a resync reconciles diverged copies Correct answer.
  2. A rebuild is a manual administrator action; a resync is a scheduled reporting job
  3. A rebuild runs only during initial cluster deployment; a resync runs continuously
  4. A rebuild applies to backups; a resync applies to snapshots

Explanation

A rebuild restores the configured redundancy level after a component such as a disk or host is lost, reconstructing data from surviving copies or parity. A resynchronization instead brings copies that drifted, for example after a brief outage, back into agreement.

Question 47Hyperconverged Infrastructure and Distributed Storage Concepts

An administrator wants maximum usable capacity for a large archive workload with infrequent access. Which data placement approach is most appropriate?

  1. Three-way replication across all nodes
  2. Erasure coding with a suitable parity level Correct answer.
  3. Single-copy placement with no redundancy
  4. Keeping a full copy on every node in the cluster

Explanation

Erasure coding stores parity fragments instead of full replicas, which raises usable capacity at the cost of more compute during rebuilds and reads. For cold, capacity-oriented workloads that trade-off is usually worthwhile.

Question 48Hyperconverged Infrastructure and Distributed Storage Concepts

A VM's storage policy requires the data to remain available if an entire host fails. Which configuration satisfies this requirement?

  1. Replicas placed on at least two separate hosts in different failure domains Correct answer.
  2. Two replicas placed on two disks within the same host
  3. One replica plus a nightly snapshot to a remote share
  4. A single replica protected by local RAID 6

Explanation

The failure domain that must be survived is the host, so copies must reside on different hosts rather than on separate disks of one host. Placement rules that spread replicas across hosts ensure a host loss leaves at least one accessible copy.

Question 49Hyperconverged Infrastructure and Distributed Storage Concepts

What is the effect of enabling deduplication on a distributed datastore?

  1. Read latency is reduced by caching blocks in memory
  2. The number of replicas is automatically doubled
  3. Identical blocks are stored once and referenced multiple times, reducing capacity consumption Correct answer.
  4. Every write is duplicated to a second site for disaster recovery

Explanation

Deduplication identifies repeated block content and stores a single copy with multiple references, which lowers raw capacity use when data contains redundancy. It is distinct from replication, which concerns fault tolerance rather than space savings.

Question 50Hyperconverged Infrastructure and Distributed Storage Concepts

Why can an all-flash hyperconverged cluster sustain lower write latency than a hybrid cluster with a magnetic tier?

  1. Flash media handle random writes without the seek and rotational delays of spinning disks Correct answer.
  2. Flash media store data without any need for replication
  3. Hybrid clusters cannot use a distributed storage layer
  4. All-flash clusters eliminate the need for a quorum mechanism

Explanation

Magnetic disks incur mechanical seek and rotational latency on random I/O, which dominates write latency in mixed workloads. Flash media have no moving parts, so random writes complete with far lower and more predictable latency.
