NEW QUESTION # 27
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. No changes occur until the policy is reapplied.
- B. The changes are queued for 60 minutes.
- C. The policy change is rejected immediately.
- D. The updated policy is serially applied to the virtual machines.
Answer: D
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 # 28
An administrator has deployed a new vSAN OSA cluster that contains eight hosts and needs to configure a storage policy for the currently deployed database virtual machines. The requirements state that if two hosts in the vSAN OSA cluster fail, all virtual machines are unaffected.
Which RAID configuration must the administrator use in this storage policy to achieve the best performance for the database virtual machines?
- A. RA1D-1
- B. RAID-0
- C. RAID-6
- D. RAID-5
Answer: A
Explanation:
Explanation
To achieve the best performance for the database virtual machines and tolerate two host failures in a vSAN OSA cluster, the administrator must use RAID-1 as the RAID configuration in the storage policy. RAID-1 is a mirroring technique that creates multiple replicas of each object across different hosts. RAID-1 provides the best performance among the available RAID configurations, as it does not involve any parity calculations or stripe splitting. To tolerate two host failures, the administrator must set the Failures to Tolerate (FTT) policy to
2, which means that each object will have three replicas. The other options are not correct. RAID-5 and RAID-6 are erasure coding techniques that split each object into data segments and parity segments across different hosts. RAID-5 can tolerate one host failure, while RAID-6 can tolerate two host failures. However, both RAID-5 and RAID-6 have lower performance than RAID-1, as they involve more complex calculations and network traffic. RAID-0 is a striping technique that splits each object into multiple stripes across different hosts. RAID-0 does not provide any data redundancy or fault tolerance, and therefore cannot tolerate any host failure.

NEW QUESTION # 29
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 # 30
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 AllPaths Down (APD) must be configured 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 Permanent Device Loss (PDL) must be confiqured 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: B,C
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 # 31
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=3 (RAID-1 Mirroring)
- C. FTT=2 (RAID-6 Erasure Coding)
- D. FTT=I (RAID-1 Mirroring)
- E. FTT=2 (RAID-1 Mirroring)
Answer: C,E
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 # 32
A vSAN administrator is using the vSAN ReadyNode Sizer to build a new environment. While entering the cluster configurations, a fellow colleague inquires about the Operations Reserve option.
What is the purpose of using this option?
- A. Configures space for external operations
- B. Reserves space for tolerating failures
- C. Allocates space forvSAN uparades
- D. Provides space for internal operations
Answer: D
Explanation:
Explanation
The purpose of using the Operations Reserve option in the vSAN ReadyNode Sizer is to provide space for internal operations such as deduplication, compression, encryption, snapshots, clones, and rebalancing. The Operations Reserve is calculated as a percentage of the total usable capacity of the vSAN cluster. The default value is 30%, but it can be adjusted based on the expected workload characteristics and data services requirements. The other options are not correct, as they do not describe the Operations Reserve option. Configuring space for external operations, reserving space for tolerating failures, and allocating space for vSAN upgrades are not part of the Operations Reserve option.

NEW QUESTION # 33
What are two characteristics of a durability component in vSAN? (Choose two.)
- A. Better Performance
- B. Better Storage utilization
- C. Better Availability
- D. Faster resynchronization
- E. Faster snapshot creation
Answer: C,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 # 34
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 ySAN configuration, replace the faulty disks, re-create the storage pool
- D. Remove the host from the cluster, replace the faulty disks, re-add the host to the cluster
Answer: B
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 :
VMware vSAN Design and Sizing Guide, page 38
NEW QUESTION # 35
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. Cluster will still be fully operational
- B. The backend performance metrics will be lost
- 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 # 36
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. vSAN performance service is not enabled.
- B. vSAN performance statistics are only available via CLI.
- C. The vRealize Operations Manager is not integrated with vSAN cluster.
- D. The administrator has read-only permissions on the cluster level.
Answer: A
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. References: About the vSAN Performance Service; Enable or Disable the Performance Service
NEW QUESTION # 37
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. There is congestion in one or more disk groups.
- C. The Virtual Machines are using PVSCSI controllers.
- D. Erasure Coding is disabled in the storage policy.
Answer: B
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 # 38
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. Change the FTT rule to "1 Failure - RAID-1 (Mirroring)", and select "Now" for Reapply to VMs
- B. Modify the FTT rule to "2 Failures - RAID-5 (Erasure Coding)"
- C. Add the "Flash read cache reservation" rule to the storage policy, and set to 0%
- D. Disable Operations reserve and Host rebuild reserve and click "Apply"
Answer: A
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 # 39
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. A valid vSAN license for the vSAN cluster
- B. Unclaimed disks in the hosts forvSAN Direct
- C. A dedicated network for vSAN Direct
- D. An integration with vSAN File Services
- E. HA enabled on the vSAN cluster
Answer: A,B
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 # 40
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. The configuration must meet the same latency and bandwidth requirement as local vSAN
- B. Either Layer 2 or Layer 3 communications can be used
- C. A leaf spine topology is required for core redundancy and reduced latency
- D. Encryption must be disabled prior to configuring HCI mesh
- E. NIC teaming must be implemented for the vSAN network vmkernel port
Answer: A,B
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 # 41
What are two prerequisites for using the TRIM and UNMAP capability of vSAN? (Choose two.)
- A. TRIM and UNMAP is enabled.
- B. The VM quest operating system supports ATA TRIM or SCSI UNMAP capability
- C. The vSAN cluster is an all-flash architecture.
- D. Change the Object Space Reservation to 100.
- E. Deduplication and compression are enabled.
Answer: A,C
Explanation:
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.
NEW QUESTION # 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. 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.
- B. Each virtual machine will be restarted on another vSAN host usingvSphere HA.
- 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.
Answer: B
Explanation:
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.

NEW QUESTION # 43
An organization wants to implement a virtual desktop infrastructure (VDI) solution on their vSAN storage.
They also need to store their applications running inside the VDI environment on vSAN storage.
Which two end-user computing (EUC) solutions could be implemented to satisfy the requirements of the organization? (Choose two.)
- A. Workspace ONE Access
- B. Workspace ONE UEM
- C. Horizon
- D. Dynamic Environment Manager
- E. Agp_ Volumes
Answer: C,D
Explanation:
Explanation
Horizon and Dynamic Environment Manager are two end-user computing (EUC) solutions that can be implemented on vSAN storage to provide a virtual desktop infrastructure (VDI) solution and store applications running inside the VDI environment. Horizon is a platform that delivers virtual desktops and applications across a variety of devices and locations, while Dynamic Environment Manager is a tool that provides personalization and dynamic policy configuration across any virtual, physical, and cloud-based Windows desktop environment. The other solutions are not directly related to VDI or application storage on vSAN.

NEW QUESTION # 44
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. Mark the virtual machine as inaccessible as vSAN is not able to locate more than 60% of the votes for the objects
- B. Mark the virtual machine as orphaned
- C. Power off the virtual machine
- D. Mark the virtual machine as compliant and automatically recover the noncompliant objects
Answer: D
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 # 45
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 host rebuild threshold.
- B. The physical disk has reached an 80% full reactive rebalance threshold.
- C. The used space on vSAN datastore exceeds the suggested slack rebuild threshold.
- D. Underutilized space is above 25-30% of the total capacity threshold.
Answer: C
Explanation:
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:

NEW QUESTION # 46
A customer has deployed a new vSAN Cluster with the following configuration:
* 6 x vSAN ReadyNodes
* All Flash
* 12 TB Raw Storage
* vSAN 8 is deployed with ESA.
VMs are configured with a RAID-5 VM policy.
During failure testing, before the new platform is placed into production one of the ESXi hosts is made unavailable.
Which RAID-5 data placement schemes will vSAN use with this failure condition?
- A. VMware HA will migrate the storage objects to another node in the cluster
- B. vSAN can protect the platform using adaptive RAID 5 if the ESXi host fails to return
- C. Some VM data will be unavailable until the failed ESXi host is recovered
- D. The data components on the hosts will be marked as degraded
Answer: D
Explanation:
Explanation
When a host in a vSAN stretched cluster goes offline, the data components on the hosts will be marked as degraded. This means that the data is still available, but the redundancy level is reduced. vSAN will try to rebuild the missing components on another host in the same fault domain, if there is enough capacity and resources. If the host comes back online within 60 minutes, vSAN will resync the data and restore the redundancy level. If the host does not come back online within 60 minutes, vSAN will rebuild the missing components on another fault domain, if there is enough capacity and resources. This will incur additional network traffic across the witness link. References: VMware vSAN Specialist v2 EXAM 5V0-22.23, page 17
NEW QUESTION # 47
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. The delay timer has not expired.
- B. Object resynchronization must be started manually.
- C. These objects belong to virtual machines, which are powered off.
- D. There are too many objects to be synchronized.
Answer: A
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.
