Question 136
What is the purpose of vSphere VM Encryption?
A) To encrypt network traffic only
B) To encrypt virtual machine files and disks at rest using encryption keys managed by a Key Management Server
C) To compress virtual machine data
D) To encrypt host memory only
Answer: B
Explanation:
vSphere VM Encryption protects virtual machine data at rest by encrypting VM files including virtual disks (VMDKs), configuration files, swap files, and snapshot files using AES-256 encryption with keys managed by an external Key Management Server (KMS) compliant with the KMIP protocol. This encryption ensures that VM data remains protected even if physical storage media is compromised or stolen.
VM Encryption operates transparently to guest operating systems and applications, with encryption and decryption occurring in the VMkernel as data is written to or read from storage. The ESXi host requests encryption keys from the configured KMS cluster, which generates and manages Data Encryption Keys (DEKs) for each encrypted VM and Key Encryption Keys (KEKs) that protect the DEKs. Keys are never stored permanently on the host, ensuring security even if hosts are compromised.
VM Encryption provides several operational benefits including integration with vSphere storage features like vMotion, Storage vMotion, snapshots, and cloning which all work seamlessly with encrypted VMs, per-VM encryption enabling selective protection of sensitive workloads while leaving less sensitive VMs unencrypted for performance, and compliance support helping organizations meet regulatory requirements for data protection. Encryption can be enabled during VM creation or added to existing VMs.
Option A is incorrect because VM Encryption protects data at rest on storage, not network traffic which is secured separately through technologies like encrypted vMotion. Option C is wrong as VM Encryption provides security through cryptographic protection, not compression which reduces storage space. Option D is incorrect because while some memory encryption technologies exist separately, VM Encryption specifically targets virtual machine files and disks on storage.
Understanding VM Encryption is essential for implementing data protection strategies that secure sensitive workloads against storage-level compromise.
Question 137
Which vSphere feature provides workload optimization recommendations based on predictive analytics?
A) Standard DRS
B) Predictive DRS
C) Storage DRS
D) Network I/O Control
Answer: B
Explanation:
Predictive DRS extends standard DRS capabilities by integrating with VMware vRealize Operations (Aria Operations) to use predictive analytics and workload forecasting for proactive workload placement and resource optimization. Unlike standard DRS which reacts to current resource utilization, Predictive DRS anticipates future demand patterns and takes preemptive action to prevent resource contention before it occurs.
Predictive DRS analyzes historical performance data, identifies workload patterns and trends, and forecasts future resource requirements for virtual machines. When it predicts that a host will experience resource contention based on forecasted demand, Predictive DRS proactively migrates VMs to other hosts with adequate capacity before performance degradation occurs. This proactive approach prevents performance issues rather than reacting to them.
The feature requires integration between vSphere and vRealize Operations with the Predictive DRS management pack installed. vRealize Operations performs the analytics and generates predictive recommendations which are sent to vCenter Server for execution through the standard DRS mechanism. Administrators can configure how aggressively Predictive DRS responds to forecasted conditions, balancing proactive optimization against migration overhead.
Option A is incorrect because standard DRS reacts to current utilization levels rather than predicting future resource needs. Option C is wrong as Storage DRS balances storage workloads but does not use predictive analytics for compute resources. Option D is incorrect because Network I/O Control manages network bandwidth allocation but does not provide predictive workload optimization.
Understanding Predictive DRS enables proactive resource management that prevents performance issues before they impact workloads.
Question 138
What is the purpose of vSphere Lifecycle Manager (vLCM)?
A) To manage virtual machine lifecycles only
B) To provide unified management of ESXi host software, firmware, and drivers
C) To monitor network performance
D) To configure storage policies
Answer: B
Explanation:
vSphere Lifecycle Manager (vLCM) provides unified, automated management of ESXi host software including the base ESXi image, drivers, firmware, and additional components through a declarative desired state model that simplifies updating and maintaining hosts throughout their lifecycle. vLCM replaces the older vSphere Update Manager (VUM) with enhanced capabilities and a streamlined approach.
vLCM operates using images that define the complete software stack for ESXi hosts including the base ESXi version, vendor add-ons for hardware compatibility, additional drivers, and firmware components. Administrators specify the desired image for clusters or individual hosts, and vLCM automatically brings hosts into compliance with that image through remediation operations. This approach ensures all cluster hosts run consistent software stacks improving compatibility and reducing configuration drift.
The platform supports two management modes: image-based management which uses complete images defining the entire software stack and is the recommended approach for new deployments, and baseline-based management which resembles the traditional VUM approach using baselines for updates. vLCM automates host remediation including entering maintenance mode, applying updates, rebooting if necessary, and returning hosts to production, with integration to DRS for workload migration during maintenance.
Option A is incorrect because vLCM manages ESXi host software lifecycle, not VM lifecycles which are handled through vCenter and DRS. Option C is wrong as network performance monitoring is provided by different tools like vRealize Operations or Network Insight. Option D is incorrect because storage policy configuration is managed through Storage Policy Based Management, not vLCM which focuses on host software.
Understanding vLCM capabilities is essential for maintaining up-to-date, secure, and consistent ESXi host configurations efficiently.
Question 139
Which feature protects virtual machines from host failures caused by hardware issues detected before complete failure?
A) vSphere HA
B) vSphere Fault Tolerance
C) Proactive HA
D) DRS
Answer: C
Explanation:
Proactive HA protects virtual machines from host failures by detecting hardware degradation or predictive failure warnings before complete host failure occurs and automatically evacuating VMs from affected hosts to healthy hosts in the cluster. This proactive approach prevents downtime by moving workloads away from hosts exhibiting warning signs rather than waiting for catastrophic failure.
Proactive HA integrates with hardware monitoring systems that detect conditions like failing memory modules, degraded storage adapters, overheating components, or failing power supplies. When monitoring systems report predictive failure warnings or degraded health status through vendor-specific health monitoring plugins, Proactive HA evaluates the severity and can automatically place the host in quarantine mode, preventing new VMs from being placed there, and initiate evacuation of existing VMs to healthy hosts.
The feature supports multiple vendor hardware monitoring systems through integration with server health monitoring capabilities. Administrators configure automation levels determining whether Proactive HA provides recommendations for manual action or automatically executes remediation. The feature also provides quarantine settings controlling how aggressively hosts are quarantined based on health status, balancing proactive protection against false positives that might unnecessarily reduce cluster capacity.
Option A is incorrect because standard vSphere HA reacts to complete host failures after they occur rather than proactively responding to early warning signs. Option B is wrong as Fault Tolerance provides continuous availability through VM replication but does not evacuate VMs based on predictive warnings. Option D is incorrect because while DRS moves VMs during Proactive HA operations, DRS itself does not detect hardware issues or trigger proactive evacuation.
Understanding Proactive HA enables infrastructure protection that prevents downtime by responding to early warning signs before catastrophic failures occur.
Question 140
What is the maximum number of virtual CPUs supported per virtual machine in vSphere 8?
A) 128 vCPUs
B) 256 vCPUs
C) 768 vCPUs
D) 1024 vCPUs
Answer: C
Explanation:
vSphere 8 supports a maximum of 768 virtual CPUs per virtual machine, representing a significant increase from previous versions and enabling virtualization of extremely large, scale-up workloads such as large databases, in-memory analytics platforms, and high-performance computing applications. This expanded vCPU support allows consolidation of workloads that previously required physical servers.
The increased vCPU limit per VM enables several use cases including large-scale database servers like SAP HANA or Oracle databases requiring massive compute capacity, in-memory big data analytics platforms processing huge datasets, EDA (Electronic Design Automation) workloads requiring extensive parallel processing, and consolidation of extremely demanding enterprise applications. These workloads can now run in VMs with performance approaching or matching physical servers.
Supporting VMs with hundreds of vCPUs requires careful configuration including adequate physical CPU cores in the host with support for symmetric multi-threading, sufficient memory allocation as large CPU counts typically correspond to large memory requirements, appropriate NUMA configuration to optimize performance, and consideration of vCPU to physical core ratios to avoid excessive oversubscription. Licensing considerations also apply as vCPU counts affect guest OS and application licensing.
Option A is incorrect because 128 vCPUs was the maximum in earlier vSphere 6.x versions. Option B is wrong as 256 vCPUs was the limit in vSphere 7.x. Option D is incorrect because 1024 vCPUs exceeds the vSphere 8 maximum of 768 vCPUs per VM.
Understanding vSphere configuration maximums helps architects design VMs that meet application requirements while staying within supported limits.
Question 141
Which vSphere feature provides application-level high availability by restarting VMs or services when failures are detected?
A) vSphere HA VM restart
B) vSphere Fault Tolerance
C) vSphere HA VM and Application Monitoring
D) DRS
Answer: C
Explanation:
vSphere HA VM and Application Monitoring extends basic host failure protection by monitoring the health of individual virtual machines and applications within them, automatically restarting VMs or resetting applications when failures are detected. This application-aware high availability ensures that not just host failures but also guest OS crashes and application hangs are detected and remediated automatically.
VM Monitoring detects guest operating system failures by monitoring VMware Tools heartbeats and I/O activity. If a VM’s guest OS stops responding but the VM is still running, VM Monitoring can restart the VM to restore service. Application Monitoring extends this capability by monitoring application-specific heartbeats through the VMware Tools Application Monitoring SDK, enabling custom applications to signal their health status and trigger automated recovery actions when problems occur.
Administrators configure monitoring sensitivity determining how quickly failures are detected and recovery actions are triggered, balancing rapid failure detection against false positives. Settings include heartbeat intervals, failure thresholds, and maximum restart attempts within a time window to prevent endless restart loops for persistently failing VMs. Application Monitoring requires applications to be instrumented with monitoring code using the VMware SDK.
Option A is incorrect because basic VM restart in HA responds to host failures but does not monitor individual VM or application health. Option B is wrong as Fault Tolerance provides continuous availability through VM replication but does not specifically monitor and restart failed applications. Option D is incorrect because DRS balances workload distribution but does not monitor or respond to application failures.
Understanding VM and Application Monitoring enables automated recovery from failures beyond host-level failures, improving overall application availability.
Question 142
What is the purpose of vSphere Enhanced vMotion Compatibility (EVC)?
A) To encrypt vMotion traffic
B) To enable vMotion between hosts with different CPU feature sets by masking CPU features to a baseline
C) To increase vMotion speed
D) To provide vMotion without shared storage
Answer: B
Explanation:
Enhanced vMotion Compatibility (EVC) enables vMotion between ESXi hosts with different CPU generations or models within the same vendor family by masking advanced CPU features to a common baseline that all hosts support. EVC ensures VMs see a consistent CPU feature set regardless of which host they run on, allowing live migration across hardware generations that would otherwise be incompatible.
EVC works by configuring the cluster to present VMs with a specific CPU feature set corresponding to a particular processor generation baseline such as Intel Haswell or AMD Opteron Generation 4. Hosts with newer processors mask advanced features not available in the baseline, presenting only the baseline features to VMs. This allows mixing older and newer hardware within the cluster while maintaining vMotion compatibility.
Administrators select an EVC mode when creating clusters, choosing the baseline that matches their oldest intended hardware or the level of CPU features their workloads require. New hosts added to the cluster must support at least the configured EVC baseline. EVC enables several use cases including gradual hardware refresh without downtime by allowing new hosts to join existing clusters, workload mobility across datacenter sites with different hardware generations, and maintenance flexibility by supporting vMotion between available hosts regardless of minor hardware differences.
Option A is incorrect because vMotion traffic encryption is a separate feature unrelated to CPU compatibility which is EVC’s purpose. Option C is wrong as EVC addresses compatibility, not migration speed which depends on network bandwidth and memory characteristics. Option D is incorrect because vMotion without shared storage is enabled by Cross-vSwitch vMotion or vSAN, not EVC which handles CPU compatibility.
Understanding EVC enables flexible cluster design that accommodates hardware diversity while maintaining vMotion capabilities.
Question 143
Which vSphere feature provides policy-based storage management and automates storage provisioning?
A) Storage DRS
B) Storage Policy Based Management (SPBM)
C) vSphere HA
D) Content Library
Answer: B
Explanation:
Storage Policy Based Management (SPBM) provides policy-based storage management that automates storage provisioning by allowing administrators to define storage requirements through policies rather than manually selecting datastores, and ensures VMs are placed on storage that meets their requirements for performance, availability, and capacity. SPBM decouples VM requirements from specific storage infrastructure details.
SPBM uses VM Storage Policies that describe storage requirements using attributes like performance tier, availability level, replication, encryption, and other characteristics. Storage providers including vSAN, traditional storage arrays, and third-party storage systems expose their capabilities through the vSphere APIs for Storage Awareness (VASA). SPBM matches VM policy requirements with storage capabilities to automatically select appropriate datastores during provisioning and ongoing operations.
The framework provides continuous compliance monitoring checking whether VMs remain on storage that meets their policies, alerting administrators when compliance issues arise due to storage configuration changes or capacity constraints. SPBM integrates throughout the VM lifecycle including initial provisioning selecting compliant storage automatically, Storage vMotion migrations respecting policies, and reconfiguration operations maintaining policy compliance. The declarative policy approach simplifies storage management at scale.
Option A is incorrect because Storage DRS balances storage workloads across datastores but does not provide policy-based provisioning based on VM requirements and storage capabilities. Option C is wrong as vSphere HA provides high availability for VMs but does not manage storage provisioning. Option D is incorrect because Content Library stores deployment content but does not provide policy-based storage management.
Understanding SPBM enables simplified, automated storage management that ensures VMs receive appropriate storage services based on their requirements.
Question 144
What is the purpose of vSphere Network I/O Control (NIOC)?
A) To encrypt network traffic
B) To allocate bandwidth to different traffic types and prevent resource contention on distributed switches
C) To configure VLANs
D) To provide network redundancy
Answer: B
Explanation:
vSphere Network I/O Control (NIOC) allocates network bandwidth on distributed switches to different traffic types ensuring that critical traffic like vMotion, Fault Tolerance, or business-critical VM traffic receives adequate bandwidth even during periods of network congestion. NIOC prevents any single traffic type from monopolizing available bandwidth and impacting other important communications.
NIOC provides bandwidth management through shares and reservations for predefined system traffic types including management, vMotion, Fault Tolerance logging, vSAN, NFS, iSCSI, and vSphere Replication, plus custom network resource pools for VM traffic. Shares determine relative priority when bandwidth is contended, with higher share values receiving proportionally more bandwidth. Reservations guarantee minimum bandwidth ensuring critical traffic always has adequate capacity.
NIOC version 3 introduces significant enhancements including user-defined network resource pools enabling granular control over VM traffic grouped by application or business unit, bandwidth allocation in absolute units like Mbps rather than just shares, and improved scalability supporting modern 25GbE and 100GbE adapters. NIOC operates on a per-distributed switch basis and requires Enterprise Plus licensing.
Option A is incorrect because network encryption is provided by separate features like encrypted vMotion or VM-level encryption, not NIOC which manages bandwidth allocation. Option C is wrong as VLAN configuration is performed through distributed switch port group settings, not NIOC. Option D is incorrect because network redundancy is achieved through NIC teaming and failover policies, while NIOC handles bandwidth management for different traffic types.
Understanding NIOC capabilities enables proper bandwidth management that ensures critical traffic receives adequate network resources during contention.
Question 145
Which feature enables vSphere to protect VMs when permanent device loss (PDL) or all paths down (APD) storage conditions occur?
A) vSphere HA Host Monitoring
B) vSphere HA VM Component Protection
C) Storage DRS
D) Fault Tolerance
Answer: B
Explanation:
vSphere HA VM Component Protection (VMCP) protects virtual machines from datastore accessibility failures including Permanent Device Loss (PDL) conditions where storage devices are permanently unavailable and All Paths Down (APD) conditions where all paths to storage are temporarily lost. VMCP automatically restarts affected VMs on hosts with datastore access when these storage failures occur.
PDL conditions occur when storage arrays explicitly report that devices are permanently unavailable, such as during LUN deletion or catastrophic array failure. VMCP detects PDL conditions and can immediately restart affected VMs on hosts that have access to the VM files, minimizing downtime. APD conditions occur when all paths to storage are lost but the storage may still be functioning, such as during network failures. VMCP provides configurable responses to APD including cautious and aggressive restart policies.
VMCP configuration includes separate policies for PDL and APD responses. For PDL, organizations typically configure aggressive VM restart since the storage is confirmed permanently unavailable. For APD, administrators choose between conservative policies that wait to see if connectivity is restored and aggressive policies that assume prolonged APD means storage failure and restart VMs preemptively. Proper configuration requires understanding storage infrastructure failure scenarios and recovery time objectives.
Option A is incorrect because Host Monitoring detects host failures through network heartbeats but does not specifically address storage accessibility failures. Option C is wrong as Storage DRS balances storage workloads but does not provide protection against storage failures. Option D is incorrect because Fault Tolerance provides continuous availability through VM replication but is designed for host failures rather than storage accessibility issues.
Understanding VMCP enables protection against storage failure scenarios that would otherwise cause extended VM downtime.
Question 146
What is the purpose of vSphere Cluster Services (vCLS)?
A) To provide backup services for VMs
B) To run cluster services in specialized agent VMs ensuring DRS and other services remain functional
C) To manage network configurations
D) To encrypt virtual machines
Answer: B
Explanation:
vSphere Cluster Services (vCLS) ensures cluster services like DRS, HA, and the vSphere Lifecycle Manager remain operational by running necessary agents in specialized, automatically managed virtual machines called vCLS VMs rather than in vCenter Server. This architecture improves service reliability and availability because cluster services continue functioning even when vCenter Server is temporarily unavailable.
vCLS automatically deploys a small number of lightweight vCLS VMs (typically 3 in most clusters) on cluster hosts. These VMs run cluster service agents that maintain cluster functionality including DRS calculations, HA monitoring, and other services. Because the vCLS VMs run within the cluster itself rather than relying on external vCenter Server availability, cluster services can continue operating during vCenter maintenance, upgrades, or failures.
The vCLS VMs are automatically managed with minimal administrator intervention required. vSphere ensures the vCLS VMs remain running, redistributes them if hosts fail, and maintains the appropriate number based on cluster configuration. Administrators should avoid manually powering off or deleting vCLS VMs as this can impact cluster service functionality. vCLS VMs consume minimal resources but should be considered when planning cluster capacity.
Option A is incorrect because backup services are provided by separate backup solutions, not vCLS which runs cluster management services. Option C is wrong as network configuration management is handled through vSphere networking features, not vCLS. Option D is incorrect because VM encryption is a separate security feature unrelated to cluster services operation.
Understanding vCLS architecture is important for maintaining healthy cluster operations and avoiding issues from inadvertent interference with automatically managed vCLS VMs.
Question 147
Which feature provides automated datastore space reclamation from deleted or migrated VM files?
A) Storage DRS
B) UNMAP/SCSI UNMAP automatic space reclamation
C) Storage vMotion
D) vSphere Replication
Answer: B
Explanation:
UNMAP/SCSI UNMAP automatic space reclamation enables ESXi to automatically reclaim unused datastore space by sending UNMAP commands to storage arrays when VM files are deleted or migrated, informing arrays that specific blocks are no longer needed and can be reclaimed. This automated process prevents datastores from appearing full of deleted data and enables thin provisioning storage to reclaim space efficiently.
Space reclamation is particularly important for thin-provisioned storage where the array only allocates physical space as data is written. Without space reclamation, deleted files continue consuming physical storage on the array even though the datastore shows free space. UNMAP operations inform the array which blocks can be freed, allowing the physical storage to be reclaimed and potentially reallocated to other uses.
vSphere provides both automatic and manual UNMAP operations. Automatic UNMAP runs as a low-priority background task reclaiming space continuously with minimal performance impact. Manual UNMAP can be triggered for immediate space reclamation when needed. The feature works with VMFS datastores and requires storage arrays that support the SCSI UNMAP command. Proper space reclamation improves storage efficiency and accurately reflects actual space utilization.
Option A is incorrect because Storage DRS balances space utilization across datastores but does not reclaim deleted space from storage arrays. Option C is wrong as Storage vMotion migrates VM storage between datastores but does not specifically handle space reclamation from deleted files. Option D is incorrect because vSphere Replication creates VM copies for disaster recovery but does not perform storage space reclamation.
Understanding space reclamation mechanisms enables efficient storage utilization especially in thin-provisioned storage environments.
Question 148
What is the maximum amount of memory supported per virtual machine in vSphere 8?
A) 2 TB
B) 4 TB
C) 6 TB
D) 12 TB
Answer: C
Explanation:
vSphere 8 supports a maximum of 6 TB (terabytes) of memory per virtual machine, enabling virtualization of extremely memory-intensive workloads such as large in-memory databases, big data analytics platforms, and high-performance computing applications that require massive amounts of RAM. This substantial memory support allows consolidation of workloads that previously required large physical servers.
The 6 TB per-VM memory limit enables several demanding use cases including large SAP HANA deployments that hold entire databases in memory for real-time analytics, in-memory data processing platforms like Apache Spark processing huge datasets, large-scale virtualized databases supporting thousands of concurrent users, and scientific computing workloads analyzing massive datasets. These memory-intensive applications can now run in VMs with near-native performance.
Configuring VMs with such large memory allocations requires careful planning including ESXi hosts with adequate physical memory to support the VMs, appropriate NUMA configuration to optimize memory access latency, sufficient memory reservations to guarantee VM performance, and consideration of memory overcommitment ratios. Guest operating systems must also support large memory configurations and may require specific versions or editions.
Option A is incorrect because 2 TB was a limitation in earlier vSphere versions before memory limits were expanded. Option B is wrong as 4 TB was the maximum in vSphere 7.x releases. Option D is incorrect because 12 TB exceeds the vSphere 8 maximum of 6 TB per VM.
Understanding memory configuration maximums helps architects design VMs that meet application requirements for memory-intensive workloads.
Question 149
Which vSphere feature provides the ability to suspend and resume entire clusters for maintenance?
A) DRS
B) vSphere Quick Boot
C) Cluster Shutdown and Startup
D) vSphere HA
Answer: C
Explanation:
Cluster Shutdown and Startup provides orchestrated shutdown and restart of all VMs and hosts in a vSphere cluster, enabling planned maintenance activities like facility power maintenance, datacenter moves, or major infrastructure upgrades that require complete environment shutdown. This feature automates complex shutdown and startup sequences that would otherwise require extensive manual coordination.
The shutdown process follows an intelligent sequence that respects VM dependencies and configurations. vSphere first gracefully shuts down VMs in the correct order accounting for startup/shutdown dependencies if configured, places hosts in maintenance mode, and finally powers off the hosts. During startup, the process reverses with hosts powered on first, brought out of maintenance mode, and then VMs started in the appropriate order.
Administrators can define startup and shutdown orders for VMs specifying dependencies where certain VMs must start before others, such as infrastructure services like DNS, domain controllers, or database servers that applications depend on. Settings include startup delays ensuring services fully initialize before dependent systems start, and shutdown delays allowing graceful application termination. The orchestration significantly reduces complexity and errors compared to manual shutdown procedures.
Option A is incorrect because DRS balances workloads across running clusters but does not orchestrate cluster-wide shutdown and startup. Option B is wrong as vSphere Quick Boot accelerates host reboots by skipping hardware initialization but does not manage cluster-level shutdown orchestration. Option D is incorrect because HA provides availability during failures but does not orchestrate planned maintenance shutdowns.
Understanding Cluster Shutdown and Startup capabilities enables efficient planned maintenance with reduced risk and manual effort.
Question 150
What is the purpose of vSphere Distributed Services Engine (DSE)?
A) To distribute VMs across hosts
B) To offload network and security services to DPUs (Data Processing Units) or SmartNICs
C) To manage storage replication
D) To provide backup services
Answer: B
Explanation:
vSphere Distributed Services Engine (DSE) offloads infrastructure services including networking, security, and storage operations from server CPUs to Data Processing Units (DPUs) or SmartNICs, freeing CPU resources for application workloads while improving performance and efficiency of infrastructure services. DSE represents a significant architectural enhancement leveraging specialized hardware accelerators.
DSE-enabled infrastructure services run on programmable network adapters equipped with dedicated processors, memory, and storage rather than consuming CPU cycles from the ESXi host. Services that can be offloaded include distributed firewall operations, load balancing, encryption/decryption, network switching, storage protocols, and data compression. This offload delivers multiple benefits including more CPU capacity available for VMs, improved performance through hardware acceleration, and enhanced security through isolation of infrastructure services.
The architecture requires compatible hardware including DPUs like NVIDIA BlueField or Intel IPU (Infrastructure Processing Unit) with appropriate firmware and drivers. vSphere and NSX must support DSE functionality for the specific use cases being offloaded. As DSE technology matures, more infrastructure services will be offloadable to specialized hardware, fundamentally changing how virtualization infrastructure is architected for efficiency and performance.
Option A is incorrect because distributing VMs across hosts is performed by DRS, not DSE which offloads infrastructure services to specialized hardware. Option C is wrong as storage replication is handled by vSphere Replication or storage array features, not DSE. Option D is incorrect because backup services are provided by separate backup solutions, while DSE focuses on offloading infrastructure services to hardware accelerators.
Understanding DSE and infrastructure offload to specialized hardware is important for architecting next-generation vSphere environments that maximize efficiency and performance.
