質問 # 28
The vSphere Client reports that the state of some components stored on the vSAN datastore are in the reconfiguring state.
Which situation causes components to enter this state?
- A. The cluster is recovering from a vSAN failure.
- B. The applied storage policy is modified.
- C. Additional storage capacity is added to the cluster.
- D. A host in the cluster enters maintenance mode.
正解：B
解説：
Explanation
The reconfiguring state indicates that some components stored on the vSAN datastore are being moved or resized to meet a new storage policy requirement. This state can occur when the applied storage policy is modified, such as changing the number of failures to tolerate, stripe width, or object space reservation. The other situations will not cause components to enter this state. References: [VMware vSAN Specialist v2 EXAM 5V0-22.23], page 31
質問 # 29
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. Deploy the new applications on the existing cluster with a RAID-6 VM storage policy and an additional stripe width of 4
- B. Perform an in-place upgrade from vSAN 7.0 U2 OSA to vSAN 8.0 ESA
- 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
正解：D
解説：
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:

質問 # 30
A vSAN administrator has a group of requirements from the application team, which mandates spreading the components across storage devices as much as possible.
What should the vSAN Administrator consider to achieve such a requirement for building a new vSAN cluster? (Choose two.)
- A. Configure disk striping in OSA
- B. Create a dedicated Storage Pool in ESA
- C. Configure disk striping in ESA
- D. Enable deduplication for vSAN
- E. Enable Force Provisioning in OSA
正解：A、D
解説：
Explanation
To spread the components across storage devices as much as possible, the vSAN administrator can configure disk striping in either OSA or ESA. Disk striping is a policy attribute that defines the number of capacity devices across which each replica of a storage object is striped. A higher number of stripes can result in better performance and availability, but also consumes more storage space. Disk striping can be configured in OSA by using the Number of disk stripes per object policy attribute, or in ESA by using the Striping Width policy attribute12 References: 1: VMware vSAN Specialist v2 Exam Preparation Guide, page 14 2: VMware vSAN Design and Sizing Guide, page 32
質問 # 31
A vSAN administrator is planning to deploy a new vSAN cluster with these requirements:
* Physical adapters share capacity among several traffic types
* Guaranteed bandwidth for vSAN during bandwidth contention
* Enhanced security
Which two actions should be taken to configure the new vSAN cluster to meet these requirements? (Choose two.)
- A. Isolate vSAN traffic in a VLAN
- B. Utilize Network I/O Control
- C. Use IOPS Limit rules in storaqe policies
- D. Enable jumbo frames
- E. Create static routes between the vSAN hosts
正解：A、B
解説：
Explanation
Utilizing Network I/O Control and isolating vSAN traffic in a VLAN are the two actions that should be taken to configure the new vSAN cluster to meet the requirements. Network I/O Control allows the vSAN administrator to create network resource poolsand assign bandwidth shares or reservations to different traffic types, such as vSAN, vMotion, or management. This ensures that vSAN traffic has guaranteed bandwidth during contention and can achieve better performance and availability. Isolating vSAN traffic in a VLAN enhances the security of the cluster by preventing unauthorized access or interference from other network segments. It also simplifies the network configuration and management by reducing the broadcast domain and avoiding IP address conflicts. Creating static routes between the vSAN hosts, using IOPS Limit rules in storage policies, and enabling jumbo frames are not necessary or recommended actions for this scenario. Static routes are not required for vSAN communication, as vSAN uses multicast or unicast depending on the version and configuration. IOPS Limit rules are used to limit the IOPS allocated to an object, which can degrade the performance and latency of the application. Jumbo frames can improve the network efficiency and throughput, but they are not mandatory for vSAN and require consistent configuration across all network devices.

質問 # 32
An administrator has to perform maintenance on one of the hosts in a three-node vSAN Cluster.
Which maintenance mode option will give the administrator the best availability for the VMs with the least effort and data transfer?
- A. Migrate all VMs and their storage from the host to a different storage system
- B. Full data migration
- C. Ensure accessibility
- D. Migrate all VMs and their storage from the host to a different vSphere cluster
正解：C
解説：
Explanation
To perform maintenance on one of the hosts in a three-node vSAN cluster with the best availability for the VMs with the least effort and data transfer, the maintenance mode option that should be used is Ensure accessibility. This option migrates only enough components to ensure that all accessible VMs remain accessible, but does not guarantee full data redundancy or policy compliance. This option is also the only evacuation mode available for a three-node cluster or a cluster with three fault domains, as there are not enough hosts to perform full data migration or re-protection after a failure. The other options are not correct.
Migrating all VMs and their storage from the host to a different storage system or a different vSphere cluster would require more effort and data transfer than using Ensure accessibility, as well as additional resources and configuration steps. Full data migration is not possible in a three-nodecluster, as it would require at least four hosts to evacuate all data from one host and maintain full redundancy and policy compliance.

質問 # 33
An administrator wants to assign a storage policy to a workload on a two-node vSAN OSA cluster consisting of three disk groups each with nested fault domains. The virtual machine must be protected against a disk or disk group failure.
Which two storage policies meet these requirements? (Choose two.)
- A. RAID-1/FTT 1
- B. RAID-5/FTT 2
- C. RAID-6/FTT 2
- D. RAID-1/FTT 3
- E. RAID-5/FTT 1
正解：A、C
解説：
Explanation
To protect a virtual machine against a disk or disk group failure, the storage policy must have a failure tolerance method (FTM) of RAID-1 or RAID-6 and a failure to tolerate (FTT) value of at least 1. RAID-1 mirrors the data across multiple disk groups, while RAID-6 uses erasure coding to stripe the data and parity information across multiple disk groups. RAID-5 is not suitable for this scenario, as it can only tolerate one disk failure per stripe. FTT 2 or 3 would require more disk groups than available in the cluster.
Therefore, the correct options are C and E. References: 1, page 8; 2, section 3.1
質問 # 34
What is the purpose of the TRIM/UNMAP process?
- A. Reclaims disk space
- B. Repairs internal cache errors
- C. Deletes orphaned snapshots
- D. Collects vSAN log files
正解：A
解説：
Explanation
The purpose of the TRIM/UNMAP process is to reclaim disk space that is no longer used by the guest operating system or the virtual machine. TRIM and UNMAP are commands that allow the guest operating system to inform the underlying storage layer that certain blocks are no longer in use and can be freed up. This process helps to improve storage efficiency and utilization,especially for thin-provisioned disks that grow dynamically as data is written to them. The other options are not correct. The TRIM/UNMAP process does not collect vSAN log files, repair internal cache errors, or delete orphaned snapshots. These are different tasks that are performed by other tools or processes.

質問 # 35
An administrator is deploying a new two-node vSAN cluster with a shared witness to a remote location.
Which requirement must be met?
- A. The ESXi hosts must have SSDs or NVMe configured for Virtual Flash File System.
- B. The ESXi hosts must have a minimum of 64 GBs of memory.
- C. The ESXi host's controller cache and advanced features must be disabled.
- D. The ESXi host's drives must be configured in RAID 1 to support Failures to Tolerate of 1.
正解：B
解説：
Explanation
To deploy a new two-node vSAN cluster with a shared witness, the administrator must meet several requirements, one of which is that the ESXi hosts must have a minimum of 64 GBs of memory. This is because each host must have enough memory to run the VMs and also to support the vSAN metadata overhead. The other options are not requirements for a two-node vSAN cluster with a shared witness. The ESXi hosts do not need SSDs or NVMe for Virtual Flash File System, as they can use any supported storage devices for vSAN. The ESXi host's controller cache and advanced features do not need to be disabled, as they can be used to improve performance and reliability. The ESXi host's drives do not need to be configured in RAID 1, as vSAN uses its own software-defined RAID mechanism to provide Failures to Tolerate.

質問 # 36
An existing vSAN OSA cluster has this specification:
Four ESXi hosts with all flash configuration
Each with two disk groups
Each disk group with one cache device and four capacity devices
There are five more device slots available per host
The CTO would like to provision new applications, and these will need more capacity and performance.
Which two methods should be used by the vSAN administrator to meet this goal with the least amount of impact? (Choose two.)
- A. Adding one more disk group per host with the same configuration
- B. Adding an ESXi host with identical device configuration
- C. Replacing all capacity devices with a similar larger device
- D. Replacing all cache devices with a larger device
- E. Adding faster cache devices
正解：A、B
解説：
Explanation
Adding one more disk group per host with the same configuration and adding an ESXi host with identical device configuration are the two methods that the vSAN administrator should use to meet the goal of increasing capacity and performance with the least amount of impact. Adding one more disk group per host will increase the raw storage capacity by 20% and also improve the performance by distributing the I/O load across more cache devices and disk groups. Adding an ESXi host with identical device configuration will increase the raw storage capacity by 25% and also improve the performance by adding more compute and network resources to the cluster. Both methods can be done without disrupting any ongoing operations or requiring any data evacuation or resynchronization.
The other options are incorrect for the following reasons:
Replacing all capacity devices with a similar larger device is incorrect because it will not increase the performance and will have a significant impact on the cluster. Replacing the capacity devices requires deleting the disk groups, which will erase all data on them and trigger a resynchronization of the affected objects. This can be disruptive and time-consuming, and also introduce additional network and disk traffic.
Replacing all cache devices with a larger device is incorrect because it will not increase the capacity and will have a significant impact on the cluster. Replacing the cache devices also requires deleting the disk groups, which will have the same drawbacks as replacing the capacity devices. Moreover, increasing the cache size may not improve the performance significantly, as vSAN OSA uses afixed cache ratio of
70% for write buffer and 30% for read cache, regardless of the cache device size.
Adding faster cache devices is incorrect because it will not increase the capacity and will have a significant impact on the cluster. Adding faster cache devices also requires deleting the disk groups, which will have the same drawbacks as replacing the cache devices. Furthermore, adding faster cache devices may not improve the performance significantly, as vSAN OSA uses a fixed cache ratio of 70% for write buffer and 30% for read cache, regardless of the cache device speed.

Expanding a vSAN Cluster
質問 # 37
An administrator must choose between deploying a virtual witness or a physical witness for a vSAN Stretched Cluster. The administrator eventually decides to use a virtual witness.
What is a benefit of selecting this approach?
- A. Increased vSAN datastore capacity
- B. Shared metadata between separate clusters
- C. Additional compute capacity for running VMs
- D. Reduced vSphere licensing
正解：D
解説：
Explanation
The correct answer is C, reduced vSphere licensing. This is because using a virtual witness appliance instead of a physical witness host can save on vSphere licensing costs, as the virtual witness appliance does not consume a vSphere license. The virtual witness appliance is a preconfigured virtual machine that runs ESXi and is distributed as an OVA file. It can be deployed on any ESXi host that has network connectivity to both data sites of the stretched cluster. The virtual witness appliance does not run any virtual machines other than itself and only hosts witness components of virtual machine objects. The other options are incorrect for the following reasons:
A, increased vSAN datastore capacity, is incorrect because using a virtual witness appliance does not affect the vSAN datastore capacity. The witness appliance does not store any customer data, only metadata, such as the size and UUID of vSAN object and components. The witness appliance also does not contribute any storage devices to the vSAN datastore.
B, shared metadata between separate clusters, is incorrect because using a virtual witness appliance does not enable sharing metadata between separate clusters. The witness appliance is dedicated to one stretched cluster and cannot serve as a witness for multiple clusters. The witness appliance maintains consistency between the two data sites of the stretched cluster by hosting witness components that act as tie-breakers in case of a site failure or network partition.
D, additional compute capacity for running VMs, is incorrect because using a virtual witness appliance does not provide additional compute capacity for running VMs. The witness appliance does not run any VMs other than itself and does not participate in any compute operations of the stretched cluster. The witness appliance only hosts witness components that consume minimal CPU and memory resources.

質問 # 38
A vSAN administrator of a non-internet connected vSAN environment wants to upgrade the environment from the vSAN 7.0 U3 to the vSAN 8.0 using vLCM.
Which option, if any, should be used as a depot in this case?
- A. Configure the vSphere Lifecycle Manager to download updates from a local UMDS-shared repository.
- B. It is not possible to use the vSphere Lifecycle Manager on a non-internet connected environment.
- C. Configure the vSphere Lifecycle Manager to download the updates from the VMware Depot using HTTPS.
- D. Configure the vSphere Lifecycle Manager to download the updates from an Online Depot.
正解：A
解説：
Explanation
To upgrade the vSAN environment from vSAN 7.0 U3 to vSAN 8.0 using vLCM in a non-internet connected environment, the administrator should configure the vSphere Lifecycle Manager to download updates from a local UMDS-shared repository. UMDS stands for Update Manager Download Service, which is a component of vSphere Lifecycle Manager that can be used to download patches and updates for ESXi hosts, virtual appliances, and VMware Tools from the VMware online depot and store them in a shared repository. The administrator can then configure the vSphere Lifecycle Manager to use the UMDS-shared repository as a custom depot for patching and upgrading the vSAN cluster. This option allows the administrator to perform offline upgrades without requiring internet access for the vSAN cluster12 References: 1: VMware vSphere Lifecycle Manager Administration, page 22 2: VMware vSphere Update Manager Download Service, page 5
質問 # 39
A vSAN administrator needs to update vSAN from version 7.0.2 to version 8.0.
Which is the correct order to perform the update?
- A. vCenter -> vSphere -> vSAN on-disk format
- B. vSAN on-disk format -> vSphere -> vCenter
- C. vSphere -> vCenter -> vSAN on-disk format
- D. vSphere -> vSAN on-disk format -> vCenter
正解：A
解説：
Explanation
The correct order to perform the update from vSAN version 7.0.2 to version 8.0 is to upgrade the vCenter Server first, then upgrade the ESXi hosts, and finally upgrade the vSAN on-disk format. This order follows the general vSphere upgrade order, which ensures compatibility and interoperability between different components. Upgrading the vCenter Server first allows it to manage and monitor the ESXi hosts and the vSAN cluster during the upgrade process. Upgrading the ESXi hosts second ensures that they have the latest software patches and drivers for vSAN. Upgrading the vSAN on-disk format last enables the new features and functionality of vSAN 8.0. The other options are not correct, as they do not follow the recommended upgrade order.
質問 # 40
What are two characteristics of the vSAN Data-At-Rest Encryption (DARE)? (Choose two.)
- A. it is not supported on Stretched Cluster environments.
- B. it continues to operate unaffected during downtime on vCenter Server.
- C. it requires Self-Encrypting Drives in order to work.
- D. it needs to be enabled together with the vSAN Data-In-Transit encryption.
- E. it is Software Defined and works independently of the Cache or Capacity drives installed on the Nodes.
正解：B、E
解説：
Explanation
Two characteristics of the vSAN Data-At-Rest Encryption (DARE) are that it is Software Defined and works independently of the Cache or Capacity drives installed on the Nodes, and that it continues to operate unaffected during downtime on vCenter Server. DARE is a feature that encrypts all data stored on vSAN disks using AES-256 XTS mode. It does not require Self-Encrypting Drives (SEDs) to work, as it uses software-based encryption keys that are generated by an external Key Management Server (KMS) or a vSphere Native Key Provider. DARE also does not depend on the type or size of the disks used in the vSAN cluster, as it encrypts data after all other processing, such as deduplication and compression, is performed.
DARE can function even when the vCenter Server is offline or unavailable, as it uses key persistence to store the encryption keys on the ESXi hosts or in a Trusted Platform Module (TPM). The hosts can access the keys without contacting the KMS or the vCenter Server. The other options are notcorrect, as they do not describe DARE accurately. DARE does not need to be enabled together with the vSAN Data-In-Transit encryption, as they are independent features that can be enabled or disabled separately. Data-In-Transit encryption encrypts data that is transmitted between hosts in a vSAN cluster using secure sockets layer (SSL) certificates. DARE is supported on Stretched Cluster environments, as it can encrypt data across multiple sites using site affinity rules.
質問 # 41
In which type of environment is vSAN storage used as a mandatory, primary storage?
- A. VMware Cloud on AWS
- B. TanzuKubernetes Grid Integrated Edition
- C. VMware Aria Automation
- D. VMware Horizon
正解：A
解説：
Explanation
VMware Cloud on AWS is a service that delivers a fully managed VMware SDDC on AWS infrastructure. It uses vSAN as the mandatory, primary storage for the SDDC clusters. vSAN provides a high-performance, resilient, and secure shared storage solution for the VMware Cloud on AWS environment. The other options are not correct, as vSAN is not mandatory or primary for them. VMware Horizon, VMware Aria Automation, and Tanzu Kubernetes Grid Integrated Edition can use vSAN as an optional or secondary storage solution, but they can also use other types of storage. References: , section 1.1; , section 1.2
質問 # 42
Which two actions are recommended when adding a host to a vSAN cluster? (Choose two.)
- A. Disable vSphere Cluster Services
- B. Disable vSAN performance service
- C. Reference the VMware Compatibility Guide
- D. Create uniformly-configured hosts
- E. Disable vSphere High Availability (HA)
正解：C、D
解説：
Explanation
When adding a host to a vSAN cluster, it is recommended to create uniformly-configured hosts and reference the VMware Compatibility Guide. These actions will ensure that the host meets the hardware and software requirements for vSAN, and that it can work seamlessly with the existing hosts in the cluster.
Uniformly-configured hosts have the same number and type of disk groups, cache devices, capacity devices, network adapters, and drivers. The VMware Compatibility Guide provides a list of certified components and firmware versions that are compatible with vSAN. The other options are not recommended, as they can cause disruption or degradation of the vSAN cluster services. Disabling vSAN performance service, vSphere Cluster Services, or vSphere High Availability (HA) can affect the monitoring, availability, and load balancing of the cluster.
質問 # 43
All of the virtual machines running on a hybrid vSAN datastore have this storage policy assigned:
Failures to Tolerate (FTT) rule is set to "2 Failures - RAID-1 (Mirroring)" The vSAN administrator needs to reduce the amount of vSAN datastore capacity the virtual machines will consume.
Which action should the vSAN administrator take to meet this goal?
- A. Disable Operations reserve and Host rebuild reserve and click "Apply"
- B. Add the "Flash read cache reservation" rule to the storage policy, and set to 0%
- C. Modify the FTT rule to "2 Failures - RAID-5 (Erasure Coding)"
- D. Change the FTT rule to "1 Failure - RAID-1 (Mirroring)", and select "Now" for Reapply to VMs
正解：D
解説：
Explanation
To reduce the amount of vSAN datastore capacity the virtual machines will consume, the vSAN administrator should change the FTT rule to "1 Failure - RAID-1 (Mirroring)", and select "Now" for Reapply to VMs. This action will reduce the number of replicas for each object from three to two, and thus free up some space on the vSAN datastore. The other options are not correct, as they will not reduce the capacity consumption.
Modifying the FTT rule to "2 Failures - RAID-5 (Erasure Coding)" will not work for a hybrid vSAN cluster, as erasure coding is only supported for all-flash clusters. Adding the "Flash read cache reservation" rule to the storage policy, and setting to 0% will not affect the capacity layer, as it only controls the amount of flash cache reserved for each object. Disabling Operations reserve and Host rebuild reserve and clicking "Apply" will not change the actual space used by the objects, as these reserves are only logicalsettings that affect how much free space is reported by vSAN. References: 1, page 9; , section 4.3
質問 # 44
A vSAN administrator has recently upgraded a vSAN cluster to 8.0 OSA and has enabled Capacity Reserve features to reduce the amount of capacity reserved for transient and rebuild operations.
Which scenario would prevent this feature from operating properly?
- A. The used space on vSAN datastore exceeds the suggested slack rebuild threshold.
- B. The used space on vSAN datastore exceeds the suggested host rebuild threshold.
- C. The physical disk has reached an 80% full reactive rebalance threshold.
- D. Underutilized space is above 25-30% of the total capacity threshold.
正解：A
解説：
Explanation
The Capacity Reserve feature in vSAN 8.0 OSA reduces the amount of capacity reserved for transient and rebuild operations by using a slack space threshold. This threshold is calculated based on the size of the largest component in the cluster and the number of failures to tolerate. If the used space on vSAN datastore exceeds the suggested slack space threshold, the feature will not operate properly and vSAN will revert to using the host rebuild reserve threshold. The other scenarios will not affect the Capacity Reserve feature. References:

質問 # 45
What is the maximum amount of capacity disks an administrator can have in disk groups on a single vSAN OSA host?
- A. 0
- B. 1
- C. 2
- D. 3
正解：C
解説：
Explanation
The maximum amount of capacity disks an administrator can have in disk groups on a single vSAN OSA host is 35. This is because a single host can have up to five disk groups, and each disk group can have up to seven capacity disks. Therefore, the maximum number of capacity disks per host is 5 x 7 = 35. The other options are not correct, as they are lower than the maximum number of capacity disks per host. References: Designing and Sizing vSAN Storage; [vSAN ReadyNode Hardware Guidance]
