質問 # 39
An administrator has 24 physical servers that need to be configured with vSAN. The administrator needs to ensure that a single rack failure is not going to affect the data availability. The number of racks used should be minimized.
What has to be done and configured to achieve this goal?
- A. Configure disk groups with a minimum of four capacity disks in each server and distribute them across four racks
- B. Distribute servers across at least three different racks and configure three fault domains
- C. Distribute servers across at least two different racks and configure two fault domains
- D. Enable deduplication and compression
正解：B
解説：
Explanation
To ensure that a single rack failure is not going to affect the data availability, while minimizing the number of racks used, the administrator has to do the following:
Distribute servers across at least three different racks. This is because vSAN supports up to three fault domains per cluster, which can be used to tolerate one or two failures. If only two racks are used, then only one failure can be tolerated4 Configure three fault domains. A fault domain is a logical grouping of hosts that share a common failure point, such as a rack or a power supply. By configuring fault domains, vSAN can place replicas of an object across different fault domains, so that a failure within one fault domain does not result in data loss orunavailability4 References: 4: VMware vSAN Specialist v2 Exam Preparation Guide, page 13
質問 # 40
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.
正解：B
解説：
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.

質問 # 41
How often does the Skyline Health interval validate online if there are new Health Checks available for vSAN?
- A. Every 12 hours
- B. Every 4 hours
- C. Every 24 hours
- D. Every 1 hour
正解：C
解説：
Explanation
The Skyline Health interval validates online if there are new Health Checks available for vSAN every 24 hours. This means that vSAN checks for new health checks from VMware Analytics Cloud once a day and updates the vSAN Health Service accordingly. The other options are not correct, as they do not match the actual frequency of the online validation. References: About the vSAN Skyline Health
質問 # 42
An administrator is responsible for managing a five-node vSAN cluster. The vSAN Cluster is configured with both vSphere High Availability (HA) and vSphere Distributed Resource Scheduler (DRS). The vSAN Cluster is currently hosting 150 virtual machines that have consumed 60% of the usable capacity.
Each virtual machine belongs to one of the following vSAN Storage Policies:
vSANPolicy1:
Site Disaster Tolerance: None
Failures to Tolerate: 1 failure - RAID-5 (Erasure Coding)
vSANPolicy2:
Site Disaster Tolerance: None
Failures to Tolerate: No data redundancy
Following an unplanned power event within the data center, the administrator has been alerted to the fact that one host has permanently failed.
What will be the impact to any virtual machine that was running on the failed host using vSANPolicy1?
- A. Each virtual machine will be restarted on another vSAN host usingvSphere HA.
- B. vSAN will defer the start of the recovery process for 60 minutes, and the virtual machines will not power on until the recovery process has been completed.
- C. Each virtual machine must be restored from backup.
- D. Each virtual machine will be unavailable for up to 90 minutes while the automatic recovery process completes.
正解：A
解説：
Explanation
The impact to any virtual machine that was running on the failed host using vSANPolicy1 is that each virtual machine will be restarted on another vSAN host using vSphere HA. This is because vSANPolicy1 has a Failures to Tolerate setting of 1 failure - RAID-5 (Erasure Coding), which means that each object has four components (three data and one parity) distributed across four hosts. If one host fails, the object can still be accessed with the remaining three components,and vSphere HA will restart the virtual machine on another host. vSAN will also try to rebuild the missing component on another host, if there is enough capacity and resources. The other options are incorrect because they either assume that the object is unavailable or that the recovery process is delayed or impossible.

質問 # 43
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 application on a new cluster with vSAN 8.0 OSA using the existing hybrid configuration
- C. Deploy the new applications on the existing cluster with a RAID-6 VM storage policy and an additional stripe width of 4
- 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 # 44
A vSAN administrator needs to enable vSAN ESA.
Which two requirements need to be met? (Choose two.)
- A. vSAN Witness Appliance
- B. vSAN ReadyNodes configuration
- C. vSAN Build Your Own configuration
- D. vSAN Advanced license
- E. vSAN Standard license
正解：B、E
解説：
Explanation
To enable vSAN ESA, two requirements that need to be met are: vSAN Standard license or higher, and vSAN ReadyNodes configuration. vSAN Standard license or higher is required to use vSAN ESA, as it is a feature that is only available in vSAN 8.0 or later versions. vSAN ESA is an optional, alternative architecture to vSAN OSA that is designed to process and store data with higher efficiency, scalability, and performance.
vSAN ReadyNodes configuration is required to use vSAN ESA, as it is a hardware configuration that is pre-configured, tested, and certified for VMware Hyper-Converged Infrastructure Software. Each vSAN ReadyNode is optimally configured for vSAN ESA with the required amount of CPU, memory, network, and storage NVMe devices. The other options are not correct. vSAN Build Your Own configuration is not supported for vSAN ESA, as it might not meet the hardware requirements or compatibility for vSAN ESA.
vSAN Witness Appliance is not required to use vSAN ESA, as it is only needed for stretched cluster or two-node cluster configurations. References: vSAN Express Storage Architecture; vSAN ReadyNode Hardware Guidance
質問 # 45
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-5/FTT 2
- B. RAID-1/FTT 3
- C. RAID-6/FTT 2
- D. RAID-1/FTT 1
- E. RAID-5/FTT 1
正解：C、D
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 # 46
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 entire storage pool, install the new devices, re-create the storage pool
- B. Remove the devices from the storage pool, replace the storage devices, claim the new devices in vSAN
- C. Remove the host from the cluster, replace the faulty disks, re-add the host to the cluster
- D. Remove the host from ySAN configuration, replace the faulty disks, re-create the storage pool
正解：B
解説：
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 :
VMware vSAN Design and Sizing Guide, page 38
質問 # 47
An architect is designing a vSAN stretched cluster and needs to ensure that data remains on a given site in case of a network partition between the sites.
Which configuration would do this?
- A. Distributed Resource Scheduler
- B. Preferred and secondary sites
- C. vCenter High Availability
- D. IvSoh ere High Availability
正解：B
解説：
Explanation
In a vSAN stretched cluster configuration, both data sites are active sites, but one site must be designated as the preferred site and the other site as the secondary or nonpreferred site. This configuration helps to ensure that data remains on a given site in case of a network partition between the sites. If the network connection between the two active sites is lost, vSAN continues operation with the preferred site, unless it is resyncing or has another issue. The site that leads to maximum data availability is the one that remains in operation. The other options are not relevant to this scenario. References: Introduction to Stretched Clusters; vSAN Stretched Cluster Guide
質問 # 48
A vSAN administrator was presented with 30 additional vSAN ReadyNodes to add to an existing vSAN cluster. There is only one administrator to complete this task.
What is the fastest approach?
- A. Use a Host Profile that was extracted from an existing host
- B. Clone the ESXi boot partition to all new hosts, since the hardware is identical
- C. Launch Quickstart to Add Hosts to a vSAN Cluster
- D. Run vim-cmd to capture, and apply the configuration from an existing host
正解：A
解説：
Explanation
To add 30 additional vSAN ReadyNodes to an existing vSAN cluster with the fastest approach, the vSAN administrator should use a Host Profile that was extracted from an existing host. AHost Profile is a configuration template that captures the settings of a reference host and applies them to other hosts or clusters.
This way, the administrator can quickly and consistently configure multiple hosts with the same settings, such as network, storage, security, and services. The other options are not correct. Running vim-cmd to capture and apply the configuration from an existing host is not as fast or convenient as using a Host Profile, as it requires running commands on each host individually. Launching Quickstart to Add Hosts to a vSAN Cluster is not possible, as Quickstart is only available for new clusters or clusters that were configured through Quickstart.
Cloning the ESXi boot partition to all new hosts is not recommended, as it might cause conflicts or errors with the host identity, network settings, or licenses. References: Configuring Hosts Using Host Profile; Using Quickstart to Configure and Expand a vSAN Cluster
質問 # 49
A vSAN administrator has a vSAN cluster that is using vSphere Lifecycle Manager (vLCM) to manage hypervisor, server drivers, and firmware. All hosts in the cluster are compliant according to the vLCM image.
A 10GB NIC on the servers is experiencing issues, and the vSAN administrator determines a new network driver will resolve the problem. Unfortunately, the required NIC driver is a newer version compared to the driver provided by the most recent Vendor Add-on.
Which action should the vSAN administrator take to ensure the latest network driver is installed on the NIC before remediation?
- A. Add an individual component to the vLCM image that has the updated NIC driver
- B. Remove theVendor Add-on from the vLCM image, and then manually install the network driver on the servers
- C. Modify the vLCM image to omit the NIC Driver, and then manually update the servers with the required NIC driver
- D. Make sure the vLCM image is configured to use the most recent version of the Vendor Add-on
正解：A
解説：
Explanation
To ensure the latest network driver is installed on the NIC before remediation, the vSAN administrator should add an individual component to the vLCM image that has the updated NIC driver. This action allows the administrator to override the driver provided by the vendor add-on and use a newer version that is compatible with the ESXi version and the hardware device. The administrator can add an individual component to the vLCM image by importing it from a ZIP file or selecting it from the vLCM depot. The other options are not correct. Making sure the vLCM image is configured to use the most recent version of the vendor add-on will not help, as the required NIC driver is a newer version than the one provided by the vendor add-on. Removing the vendor add-on from the vLCM image or modifying the vLCM image to omit the NIC driver will not ensure the latest network driver is installed on the NIC, as these actions will leave the NIC without any driver update. Manually installing or updating the network driver on the servers is not recommended, as it might cause inconsistency and non-compliance in the vLCM image.

質問 # 50
Refer to the exhibit.
An administrator uses SSH to log into a vSAN ESA host and runs theesxcli vsan debug object overview command.
The administrator notices the Healthy Components column, the last column, is reporting some components are not in a fully healthy state.
What could cause this behavior?
- A. One host is in maintenance mode with ensure accessibility.
- B. New VMDKs have been added to multiple VMs, but the storage policy has not finished applying.
- C. New physical disks have been claimed and a rebalance operation is underway.
- D. The applied Storage policy has been updated.
正解：A
解説：
Explanation
The most likely cause for some components to be not in a fully healthy state is that one host is in maintenance mode with the ensure accessibility option. This option creates temporary durability components on other hosts to maintain the required number of failures to tolerate (FTT) until the original components are restored or rebuilt. These durability components are not considered fully healthy because they do not have full redundancy and might not be compliant with the storage policy. The other options do not explain why some components are not fully healthy, as they do not affect the FTT or the compliance state of the objects.
References: Durability Components; esxcli vsan debug object overview
質問 # 51
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. Modify the FTT rule to "2 Failures - RAID-5 (Erasure Coding)"
- B. Add the "Flash read cache reservation" rule to the storage policy, and set to 0%
- C. Change the FTT rule to "1 Failure - RAID-1 (Mirroring)", and select "Now" for Reapply to VMs
- D. Disable Operations reserve and Host rebuild reserve and click "Apply"
正解：C
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 # 52
Which vSAN maintenance mode option should be used to avoid storage policy non-compliance?
- A. Partial maintenance mode
- B. Full data migration
- C. No data migration
- D. Ensure accessibility
正解：B
解説：
Explanation
To avoid storage policy non-compliance, the vSAN maintenance mode option that should be used is Full data migration. This option evacuates all data from the host to other hosts in the cluster and maintains the current object compliance state. This means that the VM objects will have access to all their replicas and will be compliant with their assigned storage policies. The other options might result in storage policy non-compliance, as they do not guarantee full data redundancy or policy adherence. Ensure accessibility only migrates the components that are essential for running the VMs, but might not have access to all their replicas.
Partial maintenance mode is not a valid option for vSAN clusters. No data migration does not evacuate any data from the host and might result in VM unavailability or data loss. References: Working with Maintenance Mode; Place a Member of vSAN Cluster in Maintenance Mode
質問 # 53
What are two prerequisites for using the TRIM and UNMAP capability of vSAN? (Choose two.)
- A. The vSAN cluster is an all-flash architecture.
- B. TRIM and UNMAP is enabled.
- C. The VM quest operating system supports ATA TRIM or SCSI UNMAP capability
- D. Change the Object Space Reservation to 100.
- E. Deduplication and compression are enabled.
正解：A、B
解説：
Explanation
The two prerequisites for using the TRIM and UNMAP capability of vSAN are:
B: The vSAN cluster is an all-flash architecture. TRIM and UNMAP are only supported on all-flash vSAN clusters, as they can reclaim space from flash devices that use thin provisioning. TRIM and UNMAP are not supported on hybrid vSAN clusters, as they cannot reclaim space from magnetic disks that use thick provisioning1.
D: TRIM and UNMAP is enabled. TRIM and UNMAP are disabled by default in vSAN, as they might have a performance impact on some workloads. To enable TRIM and UNMAP on a vSAN cluster, the administrator must use the following RVC command: vsan.unmap_support -enable2. After enabling TRIM and UNMAP, the administrator must power off and then power on all VMs that use the vSAN datastore.
質問 # 54
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 client cluster can mount up to ten remote datastores from one or more vSAN server clusters.
- B. A server vSAN cluster can serve its local datastore up to five client vSAN clusters.
- C. If vSphere HA is to work with HCI Mesh, Datastore with Permanent Device Loss (PDL) must be confiqured to Power off and restart VMs.
- 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 minimum of three nodes are required within the client cluster for vSphere HA to work
正解：D、E
解説：
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.

質問 # 55
A site administrator wishes to implement HCI mesh between two clusters on vSAN that are located in geographically separate sites and which are administered within a single datacenter.
Which two requirements should the vSAN administrator consider to accomplish this goal? (Choose two.)
- A. NIC teaming must be implemented for the vSAN network vmkernel port
- B. Encryption must be disabled prior to configuring HCI mesh
- C. Either Layer 2 or Layer 3 communications can be used
- D. A leaf spine topology is required for core redundancy and reduced latency
- E. The configuration must meet the same latency and bandwidth requirement as local vSAN
正解：C、E
解説：
Explanation
To implement HCI mesh between two clusters on vSAN that are located in geographically separate sites, the vSAN administrator should consider the following requirements:
Either Layer 2 or Layer 3 communications can be used. HCI mesh supports both Layer 2 and Layer 3 network configurations, as long as the network latency and bandwidth requirements are met3 The configuration must meet the same latency and bandwidth requirement as local vSAN. HCI mesh requires a network latency of less than or equal to 5 ms RTT between any two hosts in the participating clusters, and a network bandwidth of at least 10 Gbps for the vSAN network vmkernel port3 References: 3: VMware vSAN Specialist v2 Exam Preparation Guide, page 15
質問 # 56
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. 6 hosts
- B. 3 hosts
- C. 3 hosts
- D. 4 hosts
正解：A
解説：
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
