B) To enable centralized management and monitoring of multiple Nutanix clusters
C) To replace the Controller VM functionality
D) To manage only storage-related operations
Answer: B
Explanation:
Nutanix Prism Central is designed to provide centralized management capabilities across multiple Nutanix clusters in an enterprise environment. It serves as a single pane of glass that allows administrators to manage, monitor, and analyze multiple clusters from one unified interface, eliminating the need to log into each cluster individually.
Prism Central offers several key benefits including unified visibility across all clusters, centralized policy management, advanced analytics, capacity planning, and automated operations. It enables administrators to view the health, performance, and capacity utilization of all clusters simultaneously, making it easier to identify issues and optimize resource allocation across the entire infrastructure.
The platform also provides advanced features such as X-Play for automation, Calm for application orchestration, Flow for network security policies, and integrated reporting capabilities. These features help organizations streamline operations, reduce management complexity, and improve overall efficiency in multi-cluster deployments.
Option A is incorrect because Prism Element, not Prism Central, provides local management for individual clusters. Option C is wrong as Prism Central does not replace Controller VM functionality; the CVM continues to handle data path operations within each cluster. Option D is incorrect because Prism Central manages all aspects of the infrastructure, not just storage operations, including compute resources, networking, virtual machines, and applications.
Understanding the role of Prism Central is essential for managing enterprise-scale Nutanix deployments effectively and leveraging the full capabilities of the Nutanix platform.
Question 22
Which Nutanix feature provides automated data tiering between different storage tiers?
A) Data Locality
B) Intelligent Lifecycle Management (ILM)
C) Erasure Coding
D) Deduplication
Answer: B
Explanation:
Intelligent Lifecycle Management is a core feature of the Nutanix platform that automatically moves data between different storage tiers based on access patterns and performance requirements. This intelligent tiering ensures that frequently accessed or hot data resides on faster storage media like SSDs, while infrequently accessed or cold data is moved to higher-capacity, cost-effective storage such as HDDs.
ILM operates transparently in the background without requiring administrator intervention or manual configuration. The system continuously monitors data access patterns using sophisticated algorithms that track how often data is read or written. When data becomes cold after not being accessed for a certain period, ILM automatically migrates it from the hot tier to the cold tier, freeing up valuable SSD space for more active workloads.
This automated tiering process helps organizations optimize their storage infrastructure by balancing performance and capacity requirements. It ensures that applications receive the performance they need while maximizing the utilization of available storage resources. The feature also contributes to cost savings by allowing organizations to deploy a mix of storage media types rather than provisioning all-flash configurations.
Option A is incorrect because Data Locality refers to keeping data close to the virtual machine for optimal performance, not tiering. Option C is wrong as Erasure Coding is a data protection technique that reduces storage overhead, not a tiering mechanism. Option D is incorrect because Deduplication eliminates redundant data copies to save space but does not move data between tiers.
Question 23
What is the minimum number of nodes required to create a Nutanix cluster?
A) 1 node
B) 2 nodes
C) 3 nodes
D) 4 nodes
Answer: A
Explanation:
Nutanix supports single-node cluster deployments, making the minimum requirement just one node to create a functional cluster. This flexibility allows organizations to start small and scale out as their needs grow, which is particularly valuable for remote office branch office deployments, test and development environments, or small-scale production workloads.
Single-node clusters provide a cost-effective entry point into hyperconverged infrastructure while maintaining the same management experience and many of the same features available in larger clusters. However, it is important to note that single-node clusters have limitations in terms of high availability and data redundancy since there is no ability to replicate data across multiple nodes within the cluster.
For production environments where high availability is required, Nutanix recommends deploying at least three nodes. A three-node cluster provides the foundation for data replication with a replication factor of 2, ensuring that data remains accessible even if one node fails. This configuration strikes a balance between cost, availability, and data protection.
Option B is incorrect because while two nodes can form a cluster, this configuration requires special consideration for witness deployments to maintain availability. Option C represents the recommended minimum for production with high availability but is not the absolute minimum. Option D is incorrect as four nodes exceed the minimum requirement, though larger clusters do provide additional capacity and resilience benefits.
Understanding cluster sizing requirements is crucial for proper deployment planning and ensuring that infrastructure meets business requirements for availability and performance.
Question 24
Which protocol does Nutanix use for communication between Controller VMs in a cluster?
A) HTTPS
B) SSH
C) Internal network protocol over 10GbE
D) FTP
Answer: C
Explanation:
Nutanix Controller VMs communicate with each other using an internal network protocol that operates over high-speed network connections, typically 10 Gigabit Ethernet or faster. This internal communication is essential for maintaining cluster coherency, distributing metadata, coordinating distributed storage operations, and ensuring data consistency across all nodes in the cluster.
The internal networking between CVMs handles critical functions including metadata synchronization, data replication, cluster health monitoring, and distributed consensus operations. This communication occurs on a dedicated internal network that is separate from the production virtual machine network, ensuring that storage traffic does not interfere with application performance.
The CVMs form a distributed system where each CVM is aware of all other CVMs in the cluster and continuously exchanges information to maintain a consistent view of the cluster state. This peer-to-peer architecture eliminates single points of failure and enables the cluster to continue operating even when individual nodes experience issues.
Option A is incorrect because while HTTPS is used for accessing the Prism management interface, it is not the primary protocol for CVM-to-CVM communication. Option B is wrong as SSH is used for administrative access to CVMs but not for inter-CVM cluster operations. Option D is incorrect because FTP is not used in Nutanix cluster communications at all; it is a file transfer protocol unsuitable for the low-latency, high-throughput requirements of distributed storage operations.
Understanding CVM communication is important for network planning, troubleshooting, and ensuring optimal cluster performance through proper network configuration.
Question 25
What is the purpose of Nutanix Shadow Clones?
A) To provide backup copies of virtual machines
B) To improve read performance for multiple VMs accessing the same data
C) To replicate data across clusters
D) To create snapshots of virtual machines
Answer: B
Explanation:
Shadow Clones is an intelligent caching mechanism in Nutanix that significantly improves read performance when multiple virtual machines are accessing the same underlying data. This feature is particularly beneficial in VDI environments, where many desktops may be booted from the same master image, or in scenarios where multiple VMs run similar workloads with shared data.
When Shadow Clones detects that multiple VMs are reading the same data blocks, it automatically creates localized copies of that data on each node where the VMs are running. These cached copies, or shadow clones, allow each VM to read data locally from its host node rather than accessing it over the network from another node. This dramatically reduces network traffic and latency while improving overall read performance.
The feature operates transparently without requiring any configuration or administrator intervention. The system continuously monitors access patterns and automatically creates or removes shadow clones based on actual usage. This intelligent approach ensures that storage resources are used efficiently while providing performance benefits where they matter most.
Option A is incorrect because Shadow Clones are not backup copies; they are performance optimization caches for read operations. Option C is wrong as cross-cluster replication is handled by different features like protection domains and disaster recovery capabilities. Option D is incorrect because VM snapshots are a separate feature used for point-in-time recovery, not related to the Shadow Clones performance optimization mechanism.
Understanding Shadow Clones helps administrators appreciate how Nutanix automatically optimizes performance for common workload patterns.
Question 26
Which component in the Nutanix architecture is responsible for handling all I/O operations?
A) Hypervisor
B) Controller VM (CVM)
C) Prism Element
D) Acropolis Master
Answer: B
Explanation:
The Controller VM is the critical component in Nutanix architecture responsible for handling all input/output operations for virtual machines running on each node. Each node in a Nutanix cluster runs its own CVM, which acts as the storage controller for that node, managing all data path operations including reads, writes, data protection, and storage optimizations.
When a virtual machine needs to perform I/O operations, the requests are directed to the local CVM on the same host. The CVM then processes these requests, managing data placement, replication, compression, deduplication, and other storage services. By having a CVM on every node, Nutanix ensures that I/O operations can be handled locally whenever possible, minimizing network latency and maximizing performance.
The CVM runs the Nutanix software stack including the Distributed Storage Fabric, which coordinates with other CVMs in the cluster to provide a unified storage pool. This distributed architecture eliminates the need for traditional storage arrays and enables linear scaling of both capacity and performance as nodes are added to the cluster.
Option A is incorrect because the hypervisor hosts the virtual machines and CVMs but does not directly handle storage I/O operations. Option C is wrong as Prism Element is the management interface, not the component processing I/O operations. Option D is incorrect because the Acropolis Master is responsible for cluster-wide coordination and VM management tasks, not individual I/O operations.
Understanding the CVM’s role is fundamental to comprehending how Nutanix delivers high-performance, distributed storage services in a hyperconverged infrastructure.
Question 27
What is the default replication factor (RF) for a newly created Nutanix cluster with three or more nodes?
A) RF1
B) RF2
C) RF3
D) RF4
Answer: B
Explanation:
The default replication factor for a Nutanix cluster with three or more nodes is RF2, which means that two complete copies of data are maintained across different nodes in the cluster. This provides data redundancy and ensures that data remains accessible even if one node fails or becomes unavailable.
With RF2, data is written to two different nodes simultaneously, providing a balance between data protection and storage efficiency. This configuration allows the cluster to tolerate the failure of one node while maintaining data availability and accessibility. The storage efficiency with RF2 is approximately 50 percent, meaning that usable capacity is roughly half of the raw capacity.
Nutanix also supports RF3 for environments requiring higher levels of data protection. RF3 maintains three copies of data across the cluster and can tolerate the simultaneous failure of two nodes. However, RF3 reduces storage efficiency to approximately 33 percent and requires a minimum of five nodes to implement properly.
Option A is incorrect because RF1, which maintains only a single copy of data, is not supported for production environments due to lack of redundancy. Option C is wrong as RF3 is available but not the default setting; it must be explicitly configured. Option D is incorrect because RF4 does not exist as a supported replication factor in Nutanix clusters.
Understanding replication factors is essential for planning cluster capacity, ensuring appropriate data protection levels, and making informed decisions about balancing availability requirements with storage efficiency.
Question 28
Which Nutanix feature allows for policy-based automation of operational tasks?
A) Prism Pro
B) X-Play
C) Calm
D) Flow
Answer: B
Explanation:

It provides a powerful framework for building if-this-then-that style automation workflows that can respond to alerts, metrics, or scheduled triggers with automated remediation actions.
X-Play integrates deeply with Prism Central and can trigger actions based on various conditions such as performance anomalies, capacity thresholds, security events, or custom-defined criteria. Administrators can create playbooks using a simple graphical interface that chains together triggers, conditions, and actions without requiring programming skills. This democratizes automation and allows operations teams to implement sophisticated workflows quickly.
The feature supports a wide range of actions including sending notifications, creating tickets in ITSM systems, executing scripts, adjusting resource allocations, taking snapshots, and integrating with third-party tools through REST APIs. X-Play helps organizations reduce manual intervention, improve response times to issues, and implement consistent operational procedures across their infrastructure.
Option A is incorrect because Prism Pro is the analytics and monitoring platform that provides insights but does not directly automate tasks. Option C is wrong as Calm is focused on application lifecycle management and orchestration, not operational task automation. Option D is incorrect because Flow provides network security and microsegmentation capabilities, not automation of operational tasks.
Understanding X-Play capabilities helps administrators leverage automation to improve operational efficiency and reduce the burden of repetitive manual tasks.
Question 29
What is the purpose of the Stargate service in Nutanix?
A) Managing virtual machine lifecycles
B) Providing the data I/O path and storage management
C) Handling user authentication
D) Managing network configurations
Answer: B
Explanation:
Stargate is one of the core services running on the Nutanix Controller VM and serves as the primary data I/O interface and storage management layer. It is responsible for handling all read and write operations from virtual machines, managing data placement across the storage pool, and coordinating with other storage services to deliver high-performance, reliable storage.
When a virtual machine performs I/O operations, those requests are processed by the Stargate service, which determines where data should be stored, manages caching strategies, handles data replication, and ensures data consistency across the cluster. Stargate interacts with the underlying physical storage devices and coordinates with Stargate instances on other nodes to maintain the distributed storage fabric.
The service implements various optimization techniques including intelligent data placement, tiering between SSD and HDD storage, managing the OpLog for write buffering, and coordinating with other services like Curator for background tasks. Stargate’s architecture ensures that I/O operations are processed efficiently with minimal latency while maintaining data protection and consistency.
Option A is incorrect because VM lifecycle management is handled by the Acropolis services, not Stargate. Option C is wrong as authentication is managed by separate identity and access management components. Option D is incorrect because network configuration is handled by different services and management interfaces, not by Stargate.
Understanding Stargate’s role is crucial for comprehending the Nutanix data path and troubleshooting storage performance issues.
Question 30

Option D is incorrect because Flow provides network security and microsegmentation capabilities, not application automation.
Understanding Calm’s capabilities is essential for organizations looking to modernize application delivery, implement self-service IT, and manage applications consistently across hybrid cloud environments.
Question 31
What is the purpose of the Curator service in Nutanix?
A) Real-time I/O processing
B) Background data management and optimization tasks
C) User interface management
D) Network traffic routing
Answer: B
Explanation:
The Curator service is a critical background process in the Nutanix architecture responsible for performing various data management and optimization tasks that maintain cluster health and efficiency. Unlike Stargate which handles real-time I/O operations, Curator operates in the background during periods of lower cluster activity to perform maintenance tasks that would be too resource-intensive to execute in the data path.
Curator handles numerous important functions including disk balancing to ensure even data distribution across nodes, compression of cold data to save storage space, erasure coding to reduce data protection overhead, garbage collection to reclaim unused space, and snapshot management. These operations are scheduled intelligently to avoid impacting application performance during peak usage periods.
The service implements a distributed map-reduce framework that divides large tasks across multiple CVMs in the cluster, enabling efficient parallel processing of cluster-wide operations. This distributed approach ensures that background tasks complete quickly while maintaining cluster performance for active workloads. Curator continuously monitors cluster state and automatically triggers appropriate maintenance tasks based on configurable policies and thresholds.
Option A is incorrect because real-time I/O processing is handled by the Stargate service, not Curator. Option C is wrong as user interface management is handled by Prism and related web services. Option D is incorrect because network traffic routing is managed by the hypervisor and network configuration, not by the Curator service.
Understanding Curator’s role helps administrators appreciate how Nutanix maintains optimal cluster health and efficiency automatically without manual intervention.
Question 32
Which Nutanix feature provides network microsegmentation and security policy enforcement?
A) Prism Central
B) X-Play
C) Flow
D) Calm
Answer: C
Explanation:
Nutanix Flow is an integrated software-defined networking solution that provides network microsegmentation and security policy enforcement for applications running on Nutanix infrastructure. Flow enables administrators to implement granular security policies that control traffic between applications, tiers, and services based on application context rather than traditional network constructs.
Flow operates at the application level, allowing security policies to be defined based on categories such as application name, tier, or environment rather than IP addresses or VLANs. This application-centric approach makes security policies more flexible, portable, and easier to manage as applications are deployed, scaled, or migrated. Policies automatically follow the application regardless of where VMs are located in the infrastructure.
The platform provides visualization capabilities that map application communication patterns, helping administrators understand traffic flows and identify potential security risks. Flow supports both isolation policies that block unwanted traffic and application policies that define allowed communication patterns between application components. These policies are enforced at the virtual switch level, providing high-performance security without requiring additional appliances.
Option A is incorrect because Prism Central is the management platform, though it does serve as the interface for configuring Flow. Option B is wrong as X-Play provides operational automation, not network security. Option D is incorrect because Calm focuses on application orchestration and lifecycle management, not network microsegmentation.
Understanding Flow’s capabilities is important for implementing security best practices and protecting applications through network segmentation without the complexity of traditional network security approaches.
Question 33
What is the minimum number of nodes required in a Nutanix cluster to implement RF3?
A) 3 nodes
B) 4 nodes
C) 5 nodes
D) 6 nodes
Answer: C
Explanation:
A minimum of five nodes is required to implement Replication Factor 3 in a Nutanix cluster. RF3 maintains three complete copies of data distributed across different nodes and fault domains, providing higher availability than RF2 by allowing the cluster to tolerate the simultaneous failure of two nodes while maintaining data accessibility.
The five-node requirement exists because RF3 needs sufficient nodes to distribute the three data replicas while maintaining proper fault tolerance. With fewer than five nodes, the cluster cannot adequately distribute three copies of data and maintain availability guarantees if multiple nodes fail. The architecture ensures that data replicas are placed on different nodes and, where possible, different blocks or racks to maximize availability.
RF3 provides enhanced data protection for mission-critical workloads that require maximum availability, but it comes at the cost of reduced storage efficiency. With RF3, the storage efficiency is approximately 33 percent, meaning that only about one-third of raw capacity is available for user data. Organizations must balance the need for higher availability against the additional capacity requirements and costs.
Option A is incorrect because three nodes are insufficient to properly implement RF3 with adequate fault tolerance. Option B is wrong as four nodes still do not meet the minimum requirement for RF3 deployment. Option D is incorrect because while six nodes would work for RF3, it exceeds the minimum requirement of five nodes.
Understanding RF3 requirements is essential for capacity planning and ensuring that clusters meet availability requirements for critical workloads.
Question 34
Which storage optimization technique in Nutanix reduces data footprint by eliminating duplicate data blocks?
A) Compression
B) Deduplication
C) Erasure Coding
D) Thin Provisioning
Answer: B
Explanation:
Deduplication is a storage optimization technique that reduces the data footprint by identifying and eliminating duplicate data blocks, storing only one unique copy and creating references for subsequent instances. This is particularly effective in environments with significant data redundancy such as virtual desktop infrastructure, where many VMs may share identical operating system files and applications.
Nutanix implements deduplication at the cluster level, examining data blocks across the entire storage pool to identify duplicates. When duplicate blocks are detected, the system stores a single copy and updates metadata to point multiple references to that single block. This approach can significantly reduce storage requirements, especially for workloads with high data redundancy.
The deduplication process operates post-process, meaning data is first written to storage and then deduplicated during background operations managed by the Curator service. This approach ensures that write performance is not impacted by deduplication processing. Administrators can enable deduplication on a per-container basis, allowing for flexible deployment based on workload characteristics and expected deduplication ratios.
Option A is incorrect because compression reduces data size by encoding data more efficiently but does not eliminate duplicate blocks. Option C is wrong as Erasure Coding is a data protection technique that reduces replication overhead, not a deduplication method. Option D is incorrect because Thin Provisioning allocates storage on demand rather than eliminating duplicate data.
Understanding deduplication helps administrators optimize storage utilization and reduce infrastructure costs, particularly for workloads with high levels of data redundancy.
Question 35
What is the primary function of the Acropolis Distributed Storage Fabric (ADSF)?
A) Managing user authentication
B) Providing distributed storage services across cluster nodes
C) Configuring network settings
D) Monitoring cluster performance
Answer: B
Explanation:
The Acropolis Distributed Storage Fabric is the core distributed storage layer in Nutanix architecture that provides unified storage services across all nodes in a cluster. ADSF creates a single, distributed storage pool from the local storage devices in each node, presenting it as a unified resource that can be consumed by virtual machines and containers regardless of which node they run on.
ADSF handles critical storage functions including data distribution, replication, consistency, availability, and performance optimization. It implements sophisticated algorithms for data placement that consider factors like node capacity, performance characteristics, and fault domain distribution. The fabric ensures that data is always accessible even when nodes fail and automatically rebalances data as nodes are added or removed from the cluster.
The distributed nature of ADSF eliminates traditional storage bottlenecks and single points of failure found in legacy three-tier architectures. Each node contributes both storage capacity and processing power to the fabric, enabling linear scaling where performance and capacity grow proportionally as nodes are added. ADSF also implements various optimization techniques including caching, tiering, compression, and deduplication to maximize efficiency.
Option A is incorrect because authentication management is handled by separate identity services, not ADSF. Option C is wrong as network configuration is managed through different interfaces and services. Option D is incorrect because while ADSF is monitored, performance monitoring is provided by Prism and other management tools.
Understanding ADSF is fundamental to comprehending how Nutanix delivers enterprise storage services in a distributed, software-defined architecture.
Question 36
Which Nutanix component provides the hypervisor management capabilities in AHV environments?
A) Prism Element
B) Acropolis
C) Curator
D) Stargate
Answer: B
Explanation:

Acropolis includes multiple services that work together to deliver virtualization management, storage services, and infrastructure automation.
The Acropolis Master service is responsible for cluster-wide coordination tasks including VM management operations such as creation, cloning, migration, and deletion. It also handles resource scheduling, ensuring that VMs are placed on appropriate hosts based on resource availability and policy constraints. The Acropolis platform abstracts the underlying hypervisor, providing consistent APIs and management interfaces regardless of whether the cluster runs AHV, ESXi, or Hyper-V.
Acropolis integrates deeply with the Nutanix storage fabric and provides features like VM-centric management, high availability, live migration, and affinity policies. It exposes RESTful APIs that enable automation and integration with third-party tools and orchestration platforms. This platform approach allows Nutanix to deliver consistent functionality across different hypervisors while leveraging hypervisor-specific features where appropriate.
Option A is incorrect because Prism Element is the management user interface, not the hypervisor management layer itself. Option C is wrong as Curator handles background data management tasks, not hypervisor management. Option D is incorrect because Stargate manages the data I/O path, not hypervisor and VM operations.
Understanding Acropolis architecture is important for managing AHV environments and leveraging the full capabilities of Nutanix virtualization management.
Question 37
What is the purpose of the OpLog in Nutanix architecture?
A) Long-term data storage
B) Write buffer for improving write performance
C) Backup and recovery operations
D) Network packet logging
Answer: B
Explanation:
The OpLog is a critical component in Nutanix architecture that serves as a write buffer to improve write performance by absorbing incoming write operations on fast SSD storage before data is eventually destaged to the main storage pool. This approach ensures that write operations complete quickly, providing low-latency performance for applications while background processes handle the migration of data to appropriate storage tiers.
When a VM performs write operations, the data is first written to the OpLog on the local SSD, and simultaneously replicated to the OpLog on another node for data protection. Once the writes are acknowledged in the OpLog, the I/O operation is considered complete from the application perspective. The Curator service then manages the destaging of data from the OpLog to the extent store in the background, ensuring the OpLog remains available for new write operations.
The OpLog is sized automatically based on the available SSD capacity in each node and provides excellent write performance even for workloads with demanding I/O requirements. By decoupling the write acknowledgment from the final data placement, the OpLog enables Nutanix to deliver consistent low-latency writes while still benefiting from data optimization techniques like compression, deduplication, and intelligent tiering.
Option A is incorrect because the OpLog is not for long-term storage but rather a temporary write buffer. Option C is wrong as backup operations are handled by different mechanisms like snapshots and replication. Option D is incorrect because the OpLog does not log network packets but rather buffers write data.
Understanding the OpLog’s role helps explain how Nutanix achieves excellent write performance in hyperconverged infrastructure.
Question 38

Prism Pro also includes anomaly detection that identifies unusual behavior patterns that might indicate performance issues or security concerns. The platform generates actionable insights and recommendations, helping administrators optimize resource utilization, improve efficiency, and prevent issues before they impact users. These capabilities reduce the time spent on manual monitoring and analysis while improving infrastructure reliability.
Option A is incorrect because X-Play provides automation of operational tasks but not capacity forecasting. Option C is wrong as Flow focuses on network security and microsegmentation. Option D is incorrect because Calm is designed for application automation and orchestration, not capacity planning.
Understanding Prism Pro capabilities helps administrators move from reactive to proactive infrastructure management, ensuring resources are available when needed and optimizing infrastructure investments.
Question 39
What is the default communication port used by Prism Element for web-based management access?
A) 443
B) 80
C) 8080
D) 9440
Answer: D
Explanation:
Port 9440 is the default port used by Prism Element for secure web-based management access to individual Nutanix clusters. Administrators access the Prism Element interface by connecting to the cluster virtual IP address or any CVM IP address on port 9440 using a web browser with HTTPS protocol.
This port provides access to the comprehensive cluster management interface where administrators can monitor cluster health, manage virtual machines, configure storage containers, view performance metrics, and perform administrative tasks. The interface uses HTTPS encryption to ensure secure communication between the browser and the cluster management services.
Port 9440 must be accessible from administrator workstations and any systems that need to integrate with Nutanix management APIs. Organizations should ensure that firewall rules allow traffic on this port from trusted networks while blocking access from untrusted sources. The same port is also used for API access, enabling programmatic management and integration with automation tools.
Option A is incorrect because while port 443 is the standard HTTPS port, Nutanix uses 9440 for Prism management. Option B is wrong as port 80 is for unencrypted HTTP traffic, which is not used for Prism access. Option C is incorrect because port 8080 is commonly used for alternative web services but is not the Prism management port.
Understanding the correct management ports is essential for network configuration, firewall rule creation, and troubleshooting connectivity issues in Nutanix environments.
Question 40
Which Nutanix data protection feature creates point-in-time copies of VMs for backup and recovery purposes?
A) Replication Factor
B) Snapshots
C) Erasure Coding
D) Shadow Clones
Answer: B
Explanation:
Snapshots are a critical data protection feature in Nutanix that creates point-in-time copies of virtual machines, enabling administrators to capture VM state for backup, recovery, or testing purposes. Snapshots are space-efficient because they use a redirect-on-write mechanism that only stores changes made after the snapshot is taken, rather than creating full copies of VM data.
Nutanix snapshots can be taken manually for ad-hoc backup needs or scheduled automatically through protection policies. Multiple snapshots can be retained for each VM, providing multiple recovery points that enable administrators to restore VMs to different points in time if needed. Snapshots capture both the VM configuration and disk contents, ensuring complete recovery capability.
When a snapshot is created, subsequent writes to the VM create new data blocks while the snapshot continues to reference the original blocks, preserving the point-in-time state. This approach minimizes storage overhead while providing fast snapshot creation and efficient space utilization. Snapshots can be used locally for quick recovery or replicated to remote sites for disaster recovery purposes.
Option A is incorrect because Replication Factor provides data redundancy across nodes but does not create point-in-time copies. Option C is wrong as Erasure Coding is a space-efficient data protection technique but does not create backup copies. Option D is incorrect because Shadow Clones are performance optimization caches, not backup mechanisms.
Understanding snapshot functionality is essential for implementing effective backup and recovery strategies in Nutanix environments.
