NEW QUESTION # 14
A host in a vSAN stretched cluster goes offline during an unplanned event.
Which action will be triggered from AQC on the vSAN cluster?
- A. AQC will trigger a vMotion of VMs that went offline.
- B. AQC will recalculate the quorum on an object.
- C. AQC will create a vSAN alarm.
- D. AQC will restart the VMs that went offline.
Answer: B
Explanation:
Explanation
When a host in a vSAN stretched cluster goes offline, vSAN will use Adaptive Resync to recalculate the quorum on an object. Quorum is the minimum number of votes that an object needs to be available. For example, a RAID-1 object with two data components and one witness component needs two votes out of three to be available. If one data component goes offline, the object still has quorum and is available. However, if both data components go offline, the object loses quorum and is unavailable. Adaptive Resync will adjust the quorum requirement based on the availability of components and fault domains. For example, if one fault domain goes offline, Adaptive Resync will lower the quorum requirement to one vote out of two, so that the object can remain available with one data component and one witness component.

NEW QUESTION # 15
In which type of environment is vSAN storage used as a mandatory, primary storage?
- A. VMware Horizon
- B. TanzuKubernetes Grid Integrated Edition
- C. VMware Aria Automation
- D. VMware Cloud on AWS
Answer: D
Explanation:
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
NEW QUESTION # 16
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 3
- B. RAID-5/FTT 1
- C. RAID-1/FTT 1
- D. RAID-6/FTT 2
- E. RAID-5/FTT 2
Answer: C,D
Explanation:
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
NEW QUESTION # 17
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. If vSphere HA is to work with HCI Mesh, Datastore with AllPaths Down (APD) must be configured to Power off and restart VMs.
- B. A minimum of three nodes are required within the client cluster for vSphere HA to work
- C. A server vSAN cluster can serve its local datastore up to five client vSAN clusters.
- D. A client cluster can mount up to ten remote datastores from one or more vSAN server clusters.
- E. If vSphere HA is to work with HCI Mesh, Datastore with Permanent Device Loss (PDL) must be confiqured to Power off and restart VMs.
Answer: A,B
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 # 18
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. Make sure the vLCM image is configured to use the most recent version of the Vendor Add-on
- B. Remove theVendor Add-on from the vLCM image, and then manually install the network driver on the servers
- C. Add an individual component to the vLCM image that has the updated NIC driver
- D. Modify the vLCM image to omit the NIC Driver, and then manually update the servers with the required NIC driver
Answer: C
Explanation:
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.

NEW QUESTION # 19
After reviewing various performance charts at a cluster level, an administrator found an individual VM impacting overall performance of the vSAN cluster.
What feature should be used to introspect multiple performance metrics of a single virtual machine?
- A. esxci
- B. llOlnsiqht
- C. Skyline Health
- D. I/O Trip Analyzer
Answer: D
Explanation:
Explanation
To introspect multiple performance metrics of a single virtual machine, such as latency, throughput, IOPS, and congestion, the feature that should be used is I/O Trip Analyzer. This feature allows the administrator to diagnose the virtual machine I/O latency issues by providing a breakdown of the latencies at each layer of the vSAN stack, such as VM, host, network, and disk group. The other options are not correct, as they do not provide multiple performance metrics of a single virtual machine. esxcli is a command-line tool that can be used to manage various aspects of ESXi hosts, but it does not provide detailed performance analysis of virtual machines. Skyline Health is a feature that provides proactive notifications and recommendations for software and hardware issues based on VMware Analytics Cloud, but it does not provide granular performance metrics of virtual machines. llOlnsiqht is not a valid feature name in vSAN.

NEW QUESTION # 20
An all-flash vSAN ESA cluster contains four nodes.
Which two storage policies can the cluster satisfy? (Choose two.)
- A. FTT=I (RAID-5 Erasure Coding)
- B. FTT=2 (RAID-1 Mirroring)
- C. FTT=2 (RAID-6 Erasure Coding)
- D. FTT=3 (RAID-1 Mirroring)
- E. FTT=I (RAID-1 Mirroring)
Answer: B,C
Explanation:
Explanation
An all-flash vSAN ESA cluster with four nodes can satisfy the storage policies that require FTT=2 (RAID-1 Mirroring) or FTT=2 (RAID-6 Erasure Coding). These policies mean that the cluster can tolerate two host failures while maintaining data availability and redundancy. RAID-1 Mirroring creates three replicas of each object across different hosts, while RAID-6 Erasure Coding splits each object into four data segments and two parity segments across different hosts. Both policies require at least four hosts in the cluster to meet the FTT=2 requirement. The other options are not correct. An all-flash vSAN ESA cluster with four nodes cannot satisfy the storage policies that require FTT=3 (RAID-1 Mirroring) or FTT=1 (RAID-5 Erasure Coding). These policies mean that the cluster can tolerate three or one host failure respectively, but they require more or less hosts than four to do so. RAID-1 Mirroring with FTT=3 requires at least six hosts in the cluster to create four replicas of each object, while RAID-5 Erasure Coding with FTT=1 requires at least three hosts in the cluster to split each object into two data segments and one parity segment.

NEW QUESTION # 21
An application refactor requires significant storage that is being added for logs stored on a VM vDISK. The application VMs run on a dedicated vSAN enabled vSphere Cluster with custom CPUs and RAM, and therefore, cannot vMotion to another vSAN enabled cluster.
The administrator needs a vSAN feature that can be used to allocate additional storage from another vSAN enabled vSphere cluster to this vSAN enabled Cluster.
Which vSAN feature should be used for this purpose?
- A. vSAN HCI Mesh
- B. vSAN Stretched Clusters
- C. vSAN Replication
- D. vSAN File Services
Answer: A
Explanation:
Explanation
To allocate additional storage from another vSAN enabled vSphere cluster to this vSAN enabled Cluster, the administrator should use the vSAN HCI Mesh feature. This feature allows a vSAN cluster to consume storage resources from another vSAN cluster without requiring the hosts to be part of the same cluster. This way, the administrator can leverage the unused or underutilized storage capacity from another cluster and avoid purchasing new hardware or migrating VMs. The vSAN HCI Mesh feature also supports storage policies, encryption, deduplication and compression, and erasure coding across clusters12 References: 1: VMware vSAN Specialist v2 Exam Preparation Guide, page 15 2: VMware vSAN 7 Update 1 - HCI Mesh 3
NEW QUESTION # 22
After a planned power outage, an administrator decided to restart the vSAN cluster manually.
What is the correct sequence of steps for the administrator to follow after powering on the ESXi hosts?
- A. 1. Exit all hosts from maintenance mode.
2. Enable cluster member updates from vCenter Server only on one ESXi host.
3. Run the python reboot helper script only on one ESXi host to recover the cluster. - B. 1. Enable cluster member updates from vCenter Server on all ESXi hosts.
2. Run the python reboot helper script on all ESXi hosts to recover the cluster.
3. Exit all hosts from maintenance mode. - C. 1. Exit all hosts from maintenance mode.
2. Run the python reboot helper script only on one ESXi host to recover the cluster.
3. Enable cluster member updates from vCenter Server on all ESXi hosts. - D. 1. Enable cluster member updates from vCenter Server only on one ESXi host.
2. Run the python reboot helper script only on one ESXi host to recover the cluster.
3. Exit all hosts from maintenance mode.
Answer: D
Explanation:
Explanation
This is the sequence of steps recommended by VMware for manually restarting the vSAN cluster after a planned power outage. The steps are as follows:
Enable cluster member updates from vCenter Server only on one ESXi host. This will allow the host to receive the latest cluster membership information from vCenter Server and avoid any conflicts or inconsistencies with other hosts. The command to enable cluster member updates is esxcfg-advcfg -s 1
/VSAN/IgnoreClusterMemberListUpdates.
Run the python reboot helper script only on one ESXi host to recover the cluster. This will prepare the cluster for a manual restart by partitioning the cluster and ensuring that all hosts have consistent metadata. The command to run the python reboot helper script is python
/usr/lib/vmware/vsan/bin/reboot_helper.py prepare.
Exit all hosts from maintenance mode. This will allow the hosts to resume normal operations and join the vSAN cluster. The command to exit maintenance mode is esxcli system maintenanceMode set -e false.
The other options are incorrect for the following reasons:
B, exit all hosts from maintenance mode, run the python reboot helper script only on one ESXi host to recover the cluster, and enable cluster member updates from vCenter Server on all ESXi hosts, is incorrect because exiting all hosts from maintenance mode before running the python reboot helper script can cause data inconsistency or corruption, as the hosts may not have the latest metadata or cluster membership information. Enabling cluster member updates from vCenter Server on all ESXi hosts is also unnecessary and can cause conflicts or inconsistencies with other hosts.
C, exit all hosts from maintenance mode, enable cluster member updates from vCenter Server only on one ESXi host, and run the python reboot helper script only on one ESXi host to recover the cluster, is incorrect because exiting all hosts from maintenance mode before running the python reboot helper script can cause data inconsistency or corruption, as the hosts may not have the latest metadata or cluster membership information.
D, enable cluster member updates from vCenter Server on all ESXi hosts, run the python reboot helper script on all ESXi hosts to recover the cluster, and exit all hosts from maintenance mode, is incorrect because enabling cluster member updates from vCenter Server on all ESXi hosts is unnecessary and can causeconflicts or inconsistencies with other hosts. Running the python reboot helper script on all ESXi hosts concurrently can also cause a race condition that can result in unexpected outcomes.

NEW QUESTION # 23
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
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 # 24
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. A leaf spine topology is required for core redundancy and reduced latency
- B. The configuration must meet the same latency and bandwidth requirement as local vSAN
- C. Either Layer 2 or Layer 3 communications can be used
- D. Encryption must be disabled prior to configuring HCI mesh
- E. NIC teaming must be implemented for the vSAN network vmkernel port
Answer: B,C
Explanation:
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
NEW QUESTION # 25
A vSAN administrator encounters a non-compliant virtual machine and the compliance status of some of its objects is noncompliant. vSAN is able to locate a full replica of 55% of the votes for the noncompliant objects.
What will vSAN do with the virtual machine?
- A. Power off the virtual machine
- B. Mark the virtual machine as compliant and automatically recover the noncompliant objects
- C. Mark the virtual machine as orphaned
- D. Mark the virtual machine as inaccessible as vSAN is not able to locate more than 60% of the votes for the objects
Answer: B
Explanation:
Explanation
If vSAN is able to locate a full replica of 55% of the votes for the noncompliant objects of a virtual machine, vSAN will mark the virtual machine as compliant and automatically recover the noncompliant objects. This is because vSAN uses a quorum-based algorithm to determine object availability and compliance. An object is considered available if more than 50% of its votes are accessible, and compliant if it meets its assigned storage policy requirements. In this case, since 55% of the votes are accessible, vSAN can access a full replica of each object and restore its compliance state by rebuilding any missing or corrupted components. The other options are not correct. vSAN will not power off, mark as inaccessible, or mark as orphaned a virtual machine that has more than 50% of its votes accessible, as these actions would result in unnecessary downtime or data loss.

NEW QUESTION # 26
A six-node vSAN ESA cluster contains multiple virtual machines, and a vSAN storage policy with the rule
"Failures to tolerate" set to "1 failure - RAID-5 (Erasure Coding)" is assigned. A vSAN administrator has changed the rule in the assigned policy to "2 failures - RAID-6 (Erasure Coding)".
What is the result of this change?
- A. The changes are queued for 60 minutes.
- B. No changes occur until the policy is reapplied.
- C. The updated policy is serially applied to the virtual machines.
- D. The policy change is rejected immediately.
Answer: C
Explanation:
Explanation
The updated policy is serially applied to the virtual machines is the correct answer because changing the rule in the assigned policy will trigger a policy compliance check and a resynchronization of the affected objects.
The policy change will not be rejected, queued, or ignored, as it is a valid and supported operation. However, the policy change will not be applied in parallel, as that would cause too much network and disk traffic.
Instead, the policy change will be applied one virtual machine at a time, starting with the most critical ones, until all virtual machines are compliant with the new policy. References:

NEW QUESTION # 27
A vSAN administrator is tasked to perform an upgrade of a vSAN cluster, including firmware and drivers for its hardware. The vSAN administrator already created an image using vSphere Lifecycle Manager (vLCM).
Prior to selecting Start Remediation, which step should be taken to upgrade the complete vSAN cluster as a single task?
- A. Stage the upgrade of the vSAN cluster through vLCM
- B. Select Remediate All through vLCM to upgrade all hosts in the cluster
- C. Manually remediate one host at a time in the vSAN cluster
- D. Place all hosts in the vSAN cluster into Maintenance Mode
Answer: B
Explanation:
Explanation
To upgrade the complete vSAN cluster as a single task, including firmware and drivers for its hardware, the vSAN administrator should select Remediate All through vLCM to upgrade all hosts in the cluster. This option allows the administrator to apply the image created by vLCM to all hosts in the cluster in a single operation, without having to manually remediate each host individually. The other options are not correct, as they do not perform the upgrade of the vSAN cluster as a single task. Placing all hosts in the vSAN cluster into Maintenance Mode is not necessary, as vLCM will automatically place each host into Maintenance Mode before applying the image. Staging the upgrade of the vSAN cluster through vLCM is only a preparatory step that downloads the image components to each host, but does not apply them. Manually remediating one host at a time in the vSAN cluster is not efficient, as it requires more user intervention and time.

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.
Answer: A
Explanation:
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
NEW QUESTION # 29
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. Disable Operations reserve and Host rebuild reserve and click "Apply"
- D. Change the FTT rule to "1 Failure - RAID-1 (Mirroring)", and select "Now" for Reapply to VMs
Answer: D
Explanation:
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
NEW QUESTION # 30
An administrator is troubleshooting a vSAN performance issue. In the vSAN performance monitor there is a high latency on the vSAN cluster.
What is a possible cause of this?
- A. Jumbo frames are not enabled on the VMkernel adapters.
- B. Erasure Coding is disabled in the storage policy.
- C. The Virtual Machines are using PVSCSI controllers.
- D. There is congestion in one or more disk groups.
Answer: D
Explanation:
Explanation
A possible cause of high latency on the vSAN cluster is that there is congestion in one or more disk groups.
Congestion is a measure of how busy the storage devices are in handling I/O requests. When congestion is high, it means that the storage devices are overloaded and cannot process the requests fast enough, resulting in increased latency and reduced throughput. Congestion can be caused by various factors, such as insufficient cache capacity, disk failures, network issues, or heavy workload. The other options are not likely to cause high latency on the vSAN cluster. The Virtual Machines can use PVSCSI controllers without affecting latency, as they are optimized for high performance. Erasure Coding is a space efficiency feature that does not impact latency significantly. Jumbo frames are not required for vSAN, and enabling them does not guarantee lower latency. References: vSAN Performance Monitor; [vSAN Congestion Explained]
NEW QUESTION # 31
What is the purpose of host rebuild reserve in vSAN?
- A. Reserves space for internal operations
- B. Allocates capacity for vCLS
- C. Reserves space in case of single host failure
- D. Stores vSphere HA heartbeats
Answer: C
Explanation:
Explanation
The host rebuild reserve is a feature that allows vSAN to reserve space in the cluster for vSAN to be able to repair in case of a single host failure. This reservation is set to one host worth of capacity, which means that if one host in the vSAN cluster fails and no longer contributes storage, there is still sufficient capacity remaining in the cluster to rebuild and re-protect all vSAN objects. This feature prevents the creation of new VMs or powering on VMs if such operations consume the reserved space. By default, the host rebuild reserve is disabled, but it can be enabled in the vSAN Services configuration. The other options are not related to the hostrebuild reserve.

NEW QUESTION # 32
An administrator wishes to prevent vCenter notifications of vSAN Health status during a scheduled maintenance window.
Which action can be taken to achieve this goal?
- A. Disable the alarm from the HTML client
- B. Disable the performance service
- C. Run performance diagnostics prior to scheduled maintenance
- D. Disable SNMP service
Answer: A
Explanation:
Explanation
To prevent vCenter notifications of vSAN Health status during a scheduled maintenance window, the administrator can disable the alarm from the HTML client. This will suppress the alerts for a specified duration or until the alarm is re-enabled. Disabling the performance service, running performance diagnostics, or disabling SNMP service will not affect the vSAN Health status notifications.

NEW QUESTION # 33
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. 4 hosts
- C. 3 hosts
- D. 3 hosts
Answer: A
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 # 34
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. 5 hosts
- B. 4 hosts
- C. 3 hosts
- D. 6 hosts
Answer: C
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
