NEW QUESTION # 40
An administrator has been tasked with upgrading existing vSAN OSA cluster hosts with a SSD cache device per host to a NVMe device (hot plug).
Which fact should guide the administrator's action?
- A. The cache disk drives must have a larger capacity.
- B. The host must be removed from vSAN OSA cluster before changingcache devices.
- C. The disk groupmust be deleted on each physical host in the vSAN OSA cluster to use the NVMe device.
- D. The disk group does not need to be removed before adding new cache.
Answer: C
Explanation:
Explanation
The correct answer is A, the disk group must be deleted on each physical host in the vSAN OSA cluster to use the NVMe device. This is because vSAN OSA uses a disk group configuration where one disk is designated as a cache disk and the rest are capacity disks. To replace the cache disk with a different type or size, the disk group must be deleted first, which will erase all data on the disks and trigger a resynchronization of the affected objects. The administrator should put the host in maintenance mode and choose the option to evacuate all data before deleting the disk group. After replacing the cache disk with the NVMe device, the administrator should recreate the disk group and exit maintenance mode. The other options are incorrect for the following reasons:
B, the disk group does not need to be removed before adding new cache, is incorrect because adding a new cache disk to an existing disk group is not supported in vSAN OSA. The cache disk can only be replaced by deleting and recreating the disk group.
C, the host must be removed from vSAN OSA cluster before changing cache devices, is incorrect because removing the host from the cluster is not necessary and will cause more disruption and data loss than putting the host in maintenance mode. Removing the host will also delete its disk groups and require re-adding them after rejoining the cluster.
D, the cache disk drives must have a larger capacity, is incorrect because there is no requirement for the cache disk to have a larger capacity than the existing one. The cache disk size should be determined by the workload characteristics and performance requirements, not by the expansion process. References:

NEW QUESTION # 41
A customer wishes to host a new range of applications with high-performance requirements, specifically, low latency. The current vSAN platform is based on ReadyNode hardware and uses a vSAN 7.0 U2 hybrid topology configuration.
Which would satisfy the customer's requirement?
- A. Perform an in-place upgrade from vSAN 7.0 U2 OSA to vSAN 8.0 ESA
- B. Deploy the new applications on the existing cluster with a RAID-6 VM storage policy and an additional stripe width of 4
- C. Deploy the application on a new cluster with vSAN 8.0 OSA using the existing hybrid configuration
- D. Deploy the application on a new cluster with vSAN 8.0 ESA using a new hardware design
Answer: D
Explanation:
Explanation
Deploying the application on a new cluster with vSAN 8.0 ESA using a new hardware design is the correct answer because it will satisfy the customer's requirement for low latency. vSAN 8.0 ESA is a new architecture that uses a storage pool configuration where all disks are treated as capacity disks and use a new algorithm to distribute data across them. This improves the I/O flow, reduces the write amplification, and eliminates the cache tier bottleneck. Using a new hardware design with all-flash disks or NVMe disks will further enhance the performance and latency of the application, as these disks have faster read and write speeds than hybrid disks. Deploying the new applications on the existing cluster with a RAID-6 VM storage policy and an additionalstripe width of 4, deploying the application on a new cluster with vSAN 8.0 OSA using the existing hybrid configuration, and performing an in-place upgrade from vSAN 7.0 U2 OSA to vSAN 8.0 ESA are not valid or optimal solutions for this scenario. Deploying the new applications on the existing cluster with a RAID-6 VM storage policy and an additional stripe width of 4 will increase the resiliency and availability of the data, but it will also increase the network traffic, disk space consumption, and parity calculation overhead, which will negatively affect the latency and performance of the application. Deploying the application on a new cluster with vSAN 8.0 OSA using the existing hybrid configuration will not improve the latency significantly, as vSAN 8.0 OSA still uses the same disk group configuration as vSAN 7.0 U2 OSA, where one disk is designated as a cache disk and the rest are capacity disks. The cache disk can still become a bottleneck for high-performance applications, especially if it is not an SSD or NVMe disk. Performing an in-place upgrade from vSAN 7.0 U2 OSA to vSAN 8.0 ESA is not possible, as vSAN ESA requires a different hardware design than vSAN OSA. The existing disk groups need to be deleted and all disks need to be erased before switching to vSAN ESA. References:

NEW QUESTION # 42
A vSAN administrator needs to build a vSAN ESA cluster with RAID-5/FTT 1 adaptive storage policy.
What is the absolute minimum number of hosts that need to be part of that vSAN ESA cluster?
- A. 4 hosts
- B. 3 hosts
- C. 6 hosts
- D. 5 hosts
Answer: B
Explanation:
Explanation
To build a vSAN ESA cluster with RAID-5/FTT 1 adaptive storage policy, the absolute minimum number of hosts that need to be part of that vSAN ESA cluster is 3. This is because the vSAN ESA supports a new RAID-5 erasure coding scheme in a 2+1 configuration, which writes the data in a VM as a stripe consisting of
2 data bits and 1 parity bit, across a minimum of 3 hosts. This scheme can tolerate a single host failure (FTT=1) while consuming 1.5x the capacity of the primary data. This scheme is suitable for smaller vSAN clusters that want to reduce capacity usage without compromising performance12 References: 1: VMware vSAN Specialist v2 ExamPreparation Guide, page 15 2: Adaptive RAID-5 Erasure Coding with the Express Storage Architecture in vSAN 8 3
NEW QUESTION # 43
The Resyncing Objects view in the vCenter UI reports that some objects are currently resyncing.
Which two actions would cause this situation? (Choose two.)
- A. DRS is relocatingVMs between vSAN nodes.
- B. VM snapshot is being deleted.
- C. A change to the storage policy is applied to the objects.
- D. HA Virtual Machine Monitoring forced a VM to reboot.
- E. A host failure occurs in the cluster
Answer: C,E
Explanation:
Explanation
Two actions that would cause some objects to be currently resyncing are:
A change to the storage policy is applied to the objects. This action triggers a resynchronization of objects to make them compliant with the new policy settings, such as FTT, RAID level, stripe width, etc. The resynchronization process copies data from one host to another to create or update replicas or parity segments.
A host failure occurs in the cluster. This action causes some objects to become non-compliant with their storage policy, as they lose one or more replicas or parity segments due to the host failure. The resynchronization process rebuilds the missing components on other hosts in the cluster to restore compliance and availability.References: : VMware vSphere Storage Guide, page 129 : Monitor the Resynchronization Tasks in the vSAN Cluster 1 : VMware vSAN Specialist v2 Exam Preparation Guide, page 13
NEW QUESTION # 44
During yesterday's business hours, a cache drive failed on one of the vSAN OSA nodes. The administrator reached out to the manufacturer and received a replacement drive the following day. When the drive failed, vSAN started a resync to ensure the health of the data, and all objects are showing a healthy and compliant state. The vSAN administrator needs to replace the failed cache drive.
Which set of steps should the vSAN administrator take?
- A. Physically replace the failed cache device, and vSAN will automatically create a new disk group. Then, remove the disk group with the failed device.
- B. Physically replace the failed cache device, and vSAN will automatically allocate the storage. Then, rebalance the cache layer.
- C. Place the disk group into maintenance mode, and select Full Data Migration. Then, physically replace the failed cache device. Afterwards. vSAN will rebuild the disk group automatically.
C Remove the existing vSAN disk group and physically replace thedevice. Thencheck to verify that the ESXi host automatically detects the new device Afterwardsmanually recreate the Disk Group
Answer: B
Explanation:
Explanation
To replace a failed cache drive in a vSAN OSA cluster, the vSAN administrator should remove the existing vSAN disk group and physically replace the device. Then check to verify that the ESXi host automatically detects the new device Afterwards manually recreate the Disk Group. This is because when a cache drive fails, it affects the entire disk group that contains it, and vSAN does not allow removing only the cache drive from a disk group. Therefore, the administrator must remove the whole disk group before replacing the cache drive, and then recreate it with the new cache drive and the existing capacity drives. The other options are not correct. Physically replacing the failed cache drive without removing the disk group first might cause errors or inconsistencies in vSAN configuration. vSAN will not automatically create a new disk group or allocate storage after replacing a cache drive, as these actions require manual intervention from the administrator.
Rebalancing the cache layer is not necessary after replacing a cache drive, as vSAN will automatically distribute data across all devices in the disk group. References: Replace a Flash Caching Device on a Host; How to manually remove and recreate a vSAN disk group using esxcli
NEW QUESTION # 45
An administrator is performing maintenance on the hosts in a four-node vSAN cluster and has selected the
"Ensure Accessibility" maintenance mode option. All VMs are running with the Default Storage Policy which has not been modified from the default settings.
While one of the hosts in the cluster is down for firmware upgrade, a second host suddenly loses network connectivity to the remaining hosts.
How will the cluster be affected?
- A. The backend performance metrics will be lost
- B. Cluster will still be fully operational
- C. All VMs in the cluster will be inaccessible
- D. VMs might experience data loss
Answer: D
Explanation:
Explanation
If two hosts in a four-node vSAN cluster are down, the cluster might experience data loss because the default storage policy has a Primary level of failures to tolerate (PFTT) of 1, which means that vSAN can tolerate only one host failure. The Ensure accessibility maintenance mode option does not guarantee full data redundancy, but only ensures that all accessible VMs remain accessible. If another host fails while one host is in maintenance mode, some VMs might lose access to their data components and become unavailable or corrupted. References: vSAN Maintenance Mode Options; vSAN Cluster Configuration Limits
NEW QUESTION # 46
Due to a planned power outage, an administrator decides to shut down the vSAN cluster using the Shutdown Cluster Wizard. The administrator starts by checking the vSAN health service to confirm the cluster is healthy and then powers off all virtual machines (VMs) including vCLS VMs.
Which step needs to be taken before starting the Shutdown Cluster Wizard?
- A. Shutdown vCenter
- B. Place all ESXi hosts into maintenance mode
- C. Turn off High Availability
- D. Disable cluster member updates from vCenter Server
Answer: C
Explanation:
Explanation
To shut down the vSAN cluster using the Shutdown Cluster Wizard, the administrator needs to turn off High Availability (HA) before starting the wizard. This is because HA monitors the cluster for host failures and attempts to restart the affected VMs on other hosts. If HA is not turned off, the cluster might register host shutdowns as failures and trigger unnecessary VM restarts, which can interfere with the graceful shutdown process. Therefore, the administrator should disable HA from the Configure tab of the cluster before using the Shutdown Cluster Wizard12 References: 1: Shut Down the vSAN Cluster Using the Shutdown Cluster Wizard 3 2: Manually Shut Down and Restart the vSAN Cluster 4
NEW QUESTION # 47
A three-node vSAN OSA cluster with business critical intensive I/O workload is running out of capacity. Each host consists of five disk groups with four capacity disks. The administrator needs to expand the capacity of the vSAN datastore as soon as possible.
What should the administrator do?
- A. Add additional capacity disks to each disk group
- B. Add additional capacity by addinga vSAN ReadyNode to the cluster
- C. Enable Deduplication and Compression on the cluster level
- D. Add additional capacity by adding a disk on one host and creating a storage pool
Answer: A
Explanation:
Explanation
The correct answer is D, add additional capacity disks to each disk group. This is because adding capacity disks to existing disk groups is the fastest and easiest way to expand the capacity of the vSAN datastore without disrupting any ongoing operations or requiring additional hardware. The administrator can add up to five capacity disks per disk group in vSAN OSA, which means each host can have up to 25 capacity disks in total. The administrator should make sure that the new capacity disks are unformatted and not partitioned, so that vSAN can recognize and claim them. The administrator should also manually rebalance the cluster after adding the capacity disks to distribute the data evenly across the new devices. The other options are incorrect for the following reasons:
A, enable Deduplication and Compression on the cluster level, is incorrect because enabling Deduplication and Compression is not a recommended way to expand the capacity of the vSAN datastore. Deduplication and Compression is a space efficiency feature that reduces the logical space consumption of data by eliminating duplicate blocks and applying compression algorithms. However, enabling Deduplication and Compression requires a full data evacuation and resynchronization, which can be disruptive and time-consuming. Deduplication and Compression also introduces additional CPU and memory overhead, which can affect the performance of the cluster. Deduplication and Compression is only supported on all-flash clusters, not on hybrid clusters.
B, add additional capacity by adding a disk on one host and creating a storage pool, is incorrect because creating a storage pool is not supported in vSAN OSA. A storage pool is a new configuration introduced in vSAN 8 ESA, where all disks are treated as capacity disks and use a new algorithm to distribute data acrossthem. This configuration is not compatible with vSAN OSA, which uses a disk group configuration where one disk is designated as a cache disk and the rest are capacity disks. To use a storage pool, the administrator would need to migrate to vSAN 8 ESA on a new cluster with new hardware.
C, add additional capacity by adding a vSAN ReadyNode to the cluster, is incorrect because adding a vSAN ReadyNode to the cluster is not the fastest or easiest way to expand the capacity of the vSAN datastore. A vSAN ReadyNode is a preconfigured server that meets the hardware requirements for running vSAN. Adding a vSAN ReadyNode to the cluster would require additional hardware procurement, installation, and configuration. It would also increase the compute capacity of the cluster, which may not be necessary for the workload. Adding a vSAN ReadyNode would also trigger a resynchronization of data across the cluster, which can affect the performance and availability of the cluster. References:

NEW QUESTION # 48
Which two considerations should an architect assess when designing a HCI Mesh solution with VMware vSAN and VMware vSphere High Availability (HA)? (Choose two.)
- A. A server vSAN cluster can serve its local datastore up to five client vSAN clusters.
- B. If vSphere HA is to work with HCI Mesh, Datastore with Permanent Device Loss (PDL) must be confiqured to Power off and restart VMs.
- C. A minimum of three nodes are required within the client cluster for vSphere HA to work
- D. If vSphere HA is to work with HCI Mesh, Datastore with AllPaths Down (APD) must be configured to Power off and restart VMs.
- E. A client cluster can mount up to ten remote datastores from one or more vSAN server clusters.
Answer: C,D
Explanation:
Explanation
To design a HCI Mesh solution with VMware vSAN and VMware vSphere High Availability (HA), two considerations that the architect should assess are: A minimum of three nodes are required within the client cluster for vSphere HA to work. This is because vSphere HA needs at least three nodes in a cluster to form a quorum and elect a master host that monitors the availability of other hosts and VMs. If there are less than three nodes in a cluster, vSphere HA cannot function properly and might fail to detect or respond to host or VM failures. If vSphere HA is to work with HCI Mesh, Datastore with All Paths Down (APD) must be configured to Power off and restart VMs. This is because APD is a condition that occurs when a storage device becomes inaccessible due to loss of physical connectivity, resulting in I/O errors or timeouts for VMs that use that device. When using HCI Mesh, APD can happen if the network connection between the client cluster and the server cluster is lost or disrupted, causing the remote datastore to become unavailable. To ensure that vSphere HA can restart the affected VMs on another host that has access to their storage, Datastore with APD must be set to Power off and restart VMs in the vSphere HA settings. The other options are not correct. A server vSAN cluster can serve its local datastore up to 15 client vSAN clusters, not five. This is the maximum number of client clusters that can mount a remote datastore from a server cluster using HCI Mesh.
A client cluster can mount up to five remote datastores from one or more vSAN server clusters, not ten. This is the maximum number of remote datastores that can be mounted by a client cluster using HCI Mesh.

NEW QUESTION # 49
What is the minimum required number of hosts to provide data redundancy for a vSAN stretched cluster using dual-site mirroring and local protection with 1 failure - RAID-1 (Mirroring)?
- A. 4 hosts
- B. 3 hosts
- C. 6 hosts
- D. 3 hosts
Answer: C
Explanation:
Explanation
The minimum required number of hosts to provide data redundancy for a vSAN stretched cluster using dual-site mirroring and local protection with 1 failure - RAID-1 (Mirroring) is six hosts. This is because a vSAN stretched cluster requires at least three hosts per site, and each site must have enough hosts to tolerate one host failure. Therefore, the minimum configuration is three hosts per site, plus one witness host at a third site, for a total of six hosts. References: [VMware vSAN Specialist v2 EXAM 5V0-22.23], page 14
NEW QUESTION # 50
A vSAN administrator has a cluster configured with a Storage Pool that was moved to a new physical DC.
Upon checking on the vSAN cluster health status, one of the ESXi hosts has two storage devices in a degraded state and must be replaced.
What must the vSAN administrator do to restore the health of the vSAN cluster with minimum risk?
- A. Remove the host from the cluster, replace the faulty disks, re-add the host to the cluster
- B. Remove the host from ySAN configuration, replace the faulty disks, re-create the storage pool
- C. Remove the devices from the storage pool, replace the storage devices, claim the new devices in vSAN
- D. Remove the entire storage pool, install the new devices, re-create the storage pool
Answer: C
Explanation:
Explanation
To restore the health of the vSAN cluster with minimum risk, the vSAN administrator must remove the devices from the storage pool, replace the storage devices, and claim the new devices in vSAN. This is because removing and replacing devices in a storage pool does not affect the availability or performance of the objects stored in that pool. The storage pool automatically rebalances the objects across the remaining devices in the pool when a device is removed, and distributes the objects across the new devices when they are added. This process is faster and safer than removing and re-adding a host to the cluster, which requires resynchronization of all objects on that host4 References: 4: VMware vSphere Storage Guide, page 133 :

NEW QUESTION # 51
A vSAN administrator notices that the VMware Skyline Health: Network Latency Check reports indicate that three hosts are noncompliant.
Which action should the vSAN administrator take?
- A. Check VMKNICs, uplinks, physical switches, and associated settings
- B. Rerun the VMware Skyline Health: vSAN Cluster Partition report
- C. Immediately reboot the non-compliant hosts
- D. Place the non-compliant hosts into an isolated network partition
Answer: A
Explanation:
Explanation
The correct answer is B, check VMKNICs, uplinks, physical switches, and associated settings. This is because the VMware Skyline Health: Network Latency Check reports the network latency between vSAN hosts and displays the network latency in real time. Failure indicates that the network latency is above the normal threshold, which can affect the performance and availability of vSAN. The network latency can be caused by various factors, such as misconfiguration, congestion, or errors in the network components. The vSAN administrator should check the VMKNICs, uplinks, physical switches, and associated settings for any issues and resolve them accordingly. The vSAN administrator can also use tools such as vmkping or esxtop to test the network connectivity and performance between hosts. The other options are incorrect for the following reasons:
A, immediately reboot the non-compliant hosts, is incorrect because rebooting the non-compliant hosts is not a recommended action and can cause more disruption and data loss than resolving the network issue. Rebooting the hosts will also trigger a resynchronization of data across the cluster, which can affect the performance and availability of vSAN.
C, rerun the VMware Skyline Health: vSAN Cluster Partition report, is incorrect because rerunning the VMware Skyline Health: vSAN Cluster Partition report will not help to resolve the network latency issue. The vSAN Cluster Partition report checks if there are any network partitions in the cluster that prevent communication between hosts. The network partition can be caused by network latency, but it is not the same as network latency. The vSAN administrator should first fix the network latency issue before checking for any network partitions.
D, place the non-compliant hosts into an isolated network partition, is incorrect because placing the non-compliant hosts into an isolated network partition will not help to resolve the network latency issue.
It will also cause more problemsfor vSAN, such as data inconsistency, reduced redundancy, and degraded performance. The vSAN administrator should avoid creating any network partitions in the cluster and ensure that all hosts can communicate with each other. References:

NEW QUESTION # 52
What are two characteristics of a durability component in vSAN? (Choose two.)
- A. Better Storage utilization
- B. Faster resynchronization
- C. Better Performance
- D. Better Availability
- E. Faster snapshot creation
Answer: B,D
Explanation:
Explanation
A durability component is a temporary component that is created when a host or disk group is placed in maintenance mode with the Ensure data accessibility option, or when a host or disk group fails unexpectedly.
A durability component improves the availability of data by maintaining the required number of failures to tolerate (FTT) until the original component is restored or rebuilt. A durability component also speeds up the resynchronization process by reducing the amount of data that needs to be copied. The other characteristics are not applicable to a durability component.

NEW QUESTION # 53
After a server power failure, the administrator noticed the scheduled resyncing in the cluster monitor displays objects to be resynchronized under the pending category.
Why are there objects in this category?
- A. These objects belong to virtual machines, which are powered off.
- B. Object resynchronization must be started manually.
- C. There are too many objects to be synchronized.
- D. The delay timer has not expired.
Answer: D
Explanation:
Explanation
The reason why there are objects in the pending category of the scheduled resyncing in the cluster monitor is that the delay timer has not expired. The delay timer is a configurable setting that determines how long vSAN waits before repairing a non-compliant object after placing a host in a failed state or maintenance mode. The default value is 60 minutes, but it can be changed in the vSAN Services configuration. The pending category displays the objects with the expired delay timer that cannot be resynchronized due to insufficient resources in the current cluster or the vSAN FTT policy set on the cluster not being met. The other options are not correct.
These objects do not belong to virtual machines that are powered off, as vSAN resynchronizes all objects regardless of their power state. Object resynchronization does not need to be started manually, as vSAN initiates it automatically when the delay timer expires. There are not too many objects to be synchronized, as vSAN can handle multiple resynchronization tasks in parallel.

NEW QUESTION # 54
A vSAN administrator has an existing cluster where each ESXi host has the following:
Disk group #1 with one cache device and three capacity devices.
Disk group #2 with one cache device and two capacity devices.
What must the vSAN administrator do to expand disk group #2 to have three capacity devices?
- A. Add the new capacity device to the disk group and vSAN will automatically rebalance
- B. Put the entire ESXi host in maintenance mode, evacuate all data, then add the new capacity device
- C. Create a new disk group with a single capacity device and then migrate the existing capacity devices
- D. Put the disk group in maintenance mode, evacuate all data, then add the new capacity device
Answer: A
Explanation:
Explanation
To expand disk group #2 to have three capacity devices, the vSAN administrator should add the new capacity device to the disk group and vSAN will automatically rebalance. This action allows the administrator to increase the storage capacity of the disk group without disrupting any ongoing operations or evacuating any data. vSAN will automatically distribute data across all devices in the disk group to balance performance and utilization. The other options are not correct. Creating a new disk group with a single capacity device and then migrating the existing capacity devices is not necessary, as it would require more steps and resources than adding a device to an existing disk group. Putting the entire ESXi host or the disk group in maintenance mode and evacuating all data is not required, as it would cause downtime and data movement that could be avoided by adding a device to an existing disk group.

NEW QUESTION # 55
The DevOps team of an organization wants to deploy with persistent storage on a dedicated vSAN cluster. The storage administrator is tasked to configure the vSAN cluster and leverage the vSAN Direct feature.
Which two requirements must the administrator meet to complete this task? (Choose two.)
- A. Unclaimed disks in the hosts forvSAN Direct
- B. An integration with vSAN File Services
- C. HA enabled on the vSAN cluster
- D. A dedicated network for vSAN Direct
- E. A valid vSAN license for the vSAN cluster
Answer: A,E
Explanation:
Explanation
To configure vSAN Direct, the administrator must meet two requirements: a valid vSAN license for the vSAN cluster and unclaimed disks in the hosts for vSAN Direct. A vSAN license is required to enable vSAN features and services, including vSAN Direct. Unclaimed disks are local storage devices that are not used by vSAN or any other service, and can be claimed by vSAN Direct to create datastores for persistent storage. The other options are not requirements for vSAN Direct. HA is an optional feature that can be enabled on any cluster, but is not specific to vSAN Direct. A dedicated network for vSAN Direct is not necessary, as vSAN Direct uses the same network as vSAN. An integration with vSAN File Services is not required, as vSAN Direct does not provide file shares, but block storage. References: Set Up vSAN Direct for vSphere with Tanzu; vSAN Licensing Guide
NEW QUESTION # 56
A customer wishes to host a new range of applications with high-performance needs, specifically, low latency.
The applications are required to be hosted at company-owned edge locations, each with minimal rack space (three host slots per edge location for this project).
Which deployment options would satisfy the customer's needs, while maximizing the amount of capacity available per deployment?
- A. A new three-node vSAN 8.0 All-Flash Cluster with ESA in each edge location Each application VM configured with a RAID-5 VM storage policy
- B. A new three-node vSAN 8.0 All-Flash Cluster with OSA in each edge location Each application VM configured with a RAID-1 VM storage policy
- C. A new three-node vSAN 8.0 All-Flash Cluster with OSA in each edge location Each application VM configured with a RAID-5 VM storage policy
- D. A new three-node vSAN 8.0 All-Flash Cluster with ESA in each edge location Each application VM configured with a RAID-1 VM storage policy
Answer: B
Explanation:
Explanation
To satisfy the customer's needs for high-performance, low-latency applications at edge locations, the best deployment option is to use a new three-node vSAN 8.0 All-Flash Cluster with OSA in each edge location and configure each application VM with a RAID-1 VM storage policy. This option will provide the following benefits:
All-flash clusters offer the highest performance and lowest latency for vSAN, as they use flash devices for both cache and capacity tiers. Flash devices have faster read and write operations than magnetic disks, and they also support advanced features such as deduplication, compression, and encryption.
OSA stands for One Socket Architecture, which means that each host has only one CPU socket with multiple cores. This reduces the licensing cost and complexity of vSphere and vSAN, as well as the power consumption and cooling requirements of the hosts. OSA also improves the performance of vSAN by eliminating the NUMA effect, which is the latency caused by accessing memory or devices across different CPU sockets.
RAID-1 is a mirroring technique that creates two copies of each data component and places them on different hosts. This provides high availability and fault tolerance for the application VMs, as they can survive the failure of one host or disk. RAID-1 also offers better performance than RAID-5 or RAID-6, as it does not incur any parity overhead or additional write operations.
The other options are not optimal for the customer's needs, as they either sacrifice performance or capacity.
Option A uses RAID-5, which is an erasure coding technique that splits each data component into three data segments and one parity segment, and distributes them across four hosts. This reduces the capacity consumption by 25%, but it also increases the write latency and network traffic, as each write operation requires four hosts to participate. Option C uses ESA, which stands for Enterprise Storage Architecture, which means that each host has two CPU sockets with multiple cores. This increases the licensing cost and complexity of vSphere and vSAN, as well as the power consumption and cooling requirements of the hosts.
ESA also introduces the NUMA effect, which can degrade the performance of vSAN by adding latency to access memory or devices across different CPU sockets. Option D uses RAID-5 with ESA, which combines the disadvantages of both options A and C.
NEW QUESTION # 57
A vSAN administrator is investigating vSAN performance related problems but cannot find any vSAN performance statistics on the cluster summary page.
Why is this situation occurring?
- A. The administrator has read-only permissions on the cluster level.
- B. vSAN performance service is not enabled.
- C. The vRealize Operations Manager is not integrated with vSAN cluster.
- D. vSAN performance statistics are only available via CLI.
Answer: B
Explanation:
Explanation
The reason why the vSAN administrator cannot find any vSAN performance statistics on the cluster summary page is that the vSAN performance service is not enabled. The vSAN performance service is a feature that collects and analyzes performance metrics and displays them in graphical charts in vCenter. The vSAN performance service must be turned on manually for each vSAN cluster, as it is not enabled by default. The other options are not correct. The integration of vRealize Operations Manager with the vSAN cluster is not required to view vSAN performance statistics, as they are available in vCenter. The administrator's permissions on the cluster level do not affect the visibility of vSAN performance statistics, as they are accessible to any user who can view the cluster. vSAN performance statistics are not only available via CLI, as they can also be viewed in vCenter using the vSAN performance service.
