NEW QUESTION # 39
An administrator is upgrading multiple vSAN Witness nodes with vLCM (single image management) that are used for vSAN Stretched and two-node Clusters.
What two witness node types can the administrator upgrade? (Choose two.)
- A. Shared witness node
- B. Dedicated witness node
- C. Appliance witness node
- D. Physical witness node
- E. Nested witness node
Answer: C,E
Explanation:
Explanation
To upgrade multiple vSAN Witness nodes with vLCM (single image management) that are used for vSAN Stretched and two-node Clusters, the administrator can upgrade two witness node types: appliance witness node and nested witness node. An appliance witness node is a virtual ESXi host that runs on a physical ESXi host and contains the witness components of VM objects stored in the vSAN cluster. A nested witness node is a virtual ESXi host that runs on another virtual ESXi host and contains the witness components of VM objects stored in the vSAN cluster. Both types of witness nodes can be managed by vLCM as independent nodes since vSphere 7.0 Update 3, as long as they are version 7.0 Update 2 or later. The other options are not correct. A shared witness node is a witness node that serves multiple vSAN clusters, which is not supported by vLCM. A dedicated witness node is a witness node that serves only one vSAN cluster, which is not a specific type of witness node. A physical witness node is aphysical ESXi host that contains the witness components of VM objects stored in the vSAN cluster, which cannot be upgraded by vLCM.

NEW QUESTION # 40
When adding a disk to a host that was previously used in a decommissioned vSAN cluster the intended disk does not show among the available devices in disk management.
Which action should be taken prior to assigning the disk on disk management?
- A. Format the existing partition
- B. Create a 1GB metadata partition
- C. Create a VMFS partition
- D. Delete all device partitions
Answer: D
Explanation:
Explanation
When adding a disk to a host that was previously used in a decommissioned vSAN cluster, the disk may still have some vSAN metadata partitions that prevent it from being recognized by disk management. To resolve this issue, the disk partitions need to be deleted using either ESXCLI or partedUtil commands. This will erase all data on the disk and make it available for use in disk management.

NEW QUESTION # 41
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 compliant and automatically recover the noncompliant objects
- B. Mark the virtual machine as orphaned
- C. Mark the virtual machine as inaccessible as vSAN is not able to locate more than 60% of the votes for the objects
- D. Power off the virtual machine
Answer: A
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 # 42
A three-node vSAN OSA cluster with business critical intensive I/O workload is running out of capacity. Each host consists of five disk groups with four capacity disks. The administrator needs to expand the capacity of the vSAN datastore as soon as possible.
What should the administrator do?
- A. Add additional capacity disks to each disk group
- B. Enable Deduplication and Compression on the cluster level
- C. Add additional capacity by addinga vSAN ReadyNode to the cluster
- D. Add additional capacity by adding a disk on one host and creating a storage pool
Answer: A
Explanation:
Explanation
The correct answer is D, add additional capacity disks to each disk group. This is because adding capacity disks to existing disk groups is the fastest and easiest way to expand the capacity of the vSAN datastore without disrupting any ongoing operations or requiring additional hardware. The administrator can add up to five capacity disks per disk group in vSAN OSA, which means each host can have up to 25 capacity disks in total. The administrator should make sure that the new capacity disks are unformatted and not partitioned, so that vSAN can recognize and claim them. The administrator should also manually rebalance the cluster after adding the capacity disks to distribute the data evenly across the new devices. The other options are incorrect for the following reasons:
A, enable Deduplication and Compression on the cluster level, is incorrect because enabling Deduplication and Compression is not a recommended way to expand the capacity of the vSAN datastore. Deduplication and Compression is a space efficiency feature that reduces the logical space consumption of data by eliminating duplicate blocks and applying compression algorithms. However, enabling Deduplication and Compression requires a full data evacuation and resynchronization, which can be disruptive and time-consuming. Deduplication and Compression also introduces additional CPU and memory overhead, which can affect the performance of the cluster. Deduplication and Compression is only supported on all-flash clusters, not on hybrid clusters.
B, add additional capacity by adding a disk on one host and creating a storage pool, is incorrect because creating a storage pool is not supported in vSAN OSA. A storage pool is a new configuration introduced in vSAN 8 ESA, where all disks are treated as capacity disks and use a new algorithm to distribute data acrossthem. This configuration is not compatible with vSAN OSA, which uses a disk group configuration where one disk is designated as a cache disk and the rest are capacity disks. To use a storage pool, the administrator would need to migrate to vSAN 8 ESA on a new cluster with new hardware.
C, add additional capacity by adding a vSAN ReadyNode to the cluster, is incorrect because adding a vSAN ReadyNode to the cluster is not the fastest or easiest way to expand the capacity of the vSAN datastore. A vSAN ReadyNode is a preconfigured server that meets the hardware requirements for running vSAN. Adding a vSAN ReadyNode to the cluster would require additional hardware procurement, installation, and configuration. It would also increase the compute capacity of the cluster, which may not be necessary for the workload. Adding a vSAN ReadyNode would also trigger a resynchronization of data across the cluster, which can affect the performance and availability of the cluster. References:

NEW QUESTION # 43
A vSAN administrator has two identical VMware vSAN clusters, one for staging workloads and another for production workloads. Due to an unforeseen capacity requirement, the vSAN administrator is tasked with merging the staging vSAN cluster into the production.
Which three actions should the vSAN administrator perform on the staging cluster prior to moving the vSAN nodes to the production cluster? (Choose three.)
- A. Enable File Services
- B. Remove all capacity drives
- C. Delete all partitions from the capacity disks
- D. Disable vSAN Services
- E. Mark the disks for partial reservation
- F. Delete all Disk Groups
Answer: C,D,F
Explanation:
Explanation
The three actions that the vSAN administrator should perform on the staging cluster prior to moving the vSAN nodes to the production cluster are:
Disable vSAN Services: This will stop any vSAN-related operations on the staging cluster, such as resynchronization, rebalancing, or repair. This will also prevent any new virtual machines from being created or migrated to the staging cluster.
Delete all Disk Groups: This will remove all disks from the vSAN cluster and erase all data on them.
This will also free up the disks for use in the production cluster.
Delete all partitions from the capacity disks: This will ensure that there are no remnants of any previous vSAN configuration on the disks. This will also avoid any potential conflicts or errors when adding the disks to the production cluster.
Enabling File Services, marking the disks for partial reservation, and removing all capacity drives are not necessary or recommended actions for this scenario. Enabling File Services would add an unnecessary layer of complexity and overhead to the staging cluster. Marking the disks for partial reservation would reduce the available capacity for vSAN and potentially cause performance issues. Removing all capacity drives would leave only cache disks in the staging cluster, which would not be compatible with vSAN. References:

NEW QUESTION # 44
A customer has deployed a new vSAN cluster with the following configuration:
5 x vSAN ReadyNodes
All Flash
12 TB Raw Storage
vSAN 8 is deployed with ESA.
New VMs are configured with a RAID-5 VM policy.
Which statement is accurate?
- A. vSAN will use a 4+1 RAID-5 data placement scheme with parity will be used
- B. vSAN will spread the components across all of the disk groups
- C. vSAN will use a 2+1 RAID-5 data placement scheme with parity will be used
- D. RAID 5 will provide an FTT=2 level of protection in this case
Answer: A
Explanation:
Explanation
vSAN will use a 4+1 RAID-5 data placement scheme with parity will be used is the correct answer because vSAN 8 ESA uses adaptive RAID-5 erasure coding that depends on the number of hosts in the cluster. If the cluster has 6 or more hosts, vSAN will use a 4+1 RAID-5 scheme, where the data is written as a stripe of 4 data bits and 1 parity bit across 5 hosts. This provides a failure tolerance of 1 (FTT=1) and a space efficiency of 1.25x. If the cluster has less than 6 hosts (3 to 5), vSAN will use a 2+1 RAID-5 scheme, where the data is written as a stripe of 2 data bits and 1 parity bit across 3 hosts. This also provides a failure tolerance of 1 (FTT=1) but a space efficiency of 1.5x. In this case, the cluster has 5 hosts, so vSAN will use the 4+1 RAID-5 scheme.
The other options are incorrect for the following reasons:
A, vSAN will use a 2+1 RAID-5 data placement scheme with parity will be used, is incorrect because vSAN will only use this scheme if the cluster has less than 6 hosts but more than 2 hosts. In this case, the cluster has 5 hosts, so vSAN will use the 4+1 RAID-5 scheme.
B, RAID 5 will provide an FTT=2 level of protection in this case, is incorrect because RAID 5 can only provide an FTT=1 level of protection, regardless of the number of hosts or the data placement scheme.
To achieve an FTT=2 level of protection, vSAN would need to use RAID 6 erasure coding, which requires at least 6 hosts in the cluster.
D, vSAN will spread the components across all of the disk groups, is incorrect because vSAN will not necessarily spread the components across all of the disk groups in the cluster. vSAN will only spread the components across as many disk groups as needed to meet the storage policy requirements and to balance the load and capacity. In this case, vSAN will only need to spread the components across 5 disk groups for each stripe of RAID-5 data. References:

Adaptive RAID-5 Erasure Coding with the Express Storage Architecture in vSAN 8
NEW QUESTION # 45
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 policy change is rejected immediately.
- C. The changes are queued for 60 minutes.
- 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:
VMware vSAN Specialist v2 Exam Preparation Guide, page 9
NEW QUESTION # 46
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. Add the "Flash read cache reservation" rule to the storage policy, and set to 0%
- B. Change the FTT rule to "1 Failure - RAID-1 (Mirroring)", and select "Now" for Reapply to VMs
- C. Modify the FTT rule to "2 Failures - RAID-5 (Erasure Coding)"
- D. Disable Operations reserve and Host rebuild reserve and click "Apply"
Answer: B
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.

NEW QUESTION # 47
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. Ensure accessibility
- C. Migrate all VMs and their storage from the host to a different vSphere cluster
- D. Full data migration
Answer: B
Explanation:
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.

NEW QUESTION # 48
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. Utilize Network I/O Control
- B. Create static routes between the vSAN hosts
- C. Use IOPS Limit rules in storaqe policies
- D. Isolate vSAN traffic in a VLAN
- E. Enable jumbo frames
Answer: A,D
Explanation:
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.

NEW QUESTION # 49
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 application on a new cluster with vSAN 8.0 OSA using the existing hybrid configuration
- 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 ESA using a new hardware design
- D. Deploy the new applications on the existing cluster with a RAID-6 VM storage policy and an additional stripe width of 4
Answer: C
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 # 50
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-5/FTT 1
- C. RAID-6/FTT 2
- D. RAID-1/FTT 1
- E. RAID-1/FTT 3
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 # 51
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. The Virtual Machines are using PVSCSI controllers.
- B. Erasure Coding is disabled in the storage policy.
- C. There is congestion in one or more disk groups.
- D. Jumbo frames are not enabled on the VMkernel adapters.
Answer: C
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 # 52
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. Disable vSphere High Availability (HA)
- D. Create uniformly-configured hosts
- E. Reference the VMware Compatibility Guide
Answer: D,E
Explanation:
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.
NEW QUESTION # 53
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 Stretched Clusters
- B. vSAN Replication
- C. vSAN File Services
- D. vSAN HCI Mesh
Answer: D
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
