NEW QUESTION # 27
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 devices from the storage pool, replace the storage devices, claim the new devices in vSAN
- B. Remove the host from ySAN configuration, replace the faulty disks, re-create the storage pool
- C. Remove the host from the cluster, replace the faulty disks, re-add the host to the cluster
- D. Remove the entire storage pool, install the new devices, re-create the storage pool
Answer: A
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 :

NEW QUESTION # 28
A vSAN administrator has recently upgraded a vSAN cluster to 8.0 OSA and has enabled Capacity Reserve features to reduce the amount of capacity reserved for transient and rebuild operations.
Which scenario would prevent this feature from operating properly?
- A. The used space on vSAN datastore exceeds the suggested slack rebuild threshold.
- B. The used space on vSAN datastore exceeds the suggested host rebuild threshold.
- C. The physical disk has reached an 80% full reactive rebalance threshold.
- D. Underutilized space is above 25-30% of the total capacity threshold.
Answer: A
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 # 29
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 File Services
- B. vSAN HCI Mesh
- C. vSAN Replication
- D. vSAN Stretched Clusters
Answer: B
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 # 30
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. These objects belong to virtual machines, which are powered off.
- C. Object resynchronization must be started manually.
- 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.

NEW QUESTION # 31
An existing vSAN OSA cluster has this specification:
Four ESXi hosts with all flash configuration
Each with two disk groups
Each disk group with one cache device and four capacity devices
There are five more device slots available per host
The CTO would like to provision new applications, and these will need more capacity and performance.
Which two methods should be used by the vSAN administrator to meet this goal with the least amount of impact? (Choose two.)
- A. Adding one more disk group per host with the same configuration
- B. Adding faster cache devices
- C. Replacing all capacity devices with a similar larger device
- D. Adding an ESXi host with identical device configuration
- E. Replacing all cache devices with a larger device
Answer: A,D
Explanation:
Explanation
Adding one more disk group per host with the same configuration and adding an ESXi host with identical device configuration are the two methods that the vSAN administrator should use to meet the goal of increasing capacity and performance with the least amount of impact. Adding one more disk group per host will increase the raw storage capacity by 20% and also improve the performance by distributing the I/O load across more cache devices and disk groups. Adding an ESXi host with identical device configuration will increase the raw storage capacity by 25% and also improve the performance by adding more compute and network resources to the cluster. Both methods can be done without disrupting any ongoing operations or requiring any data evacuation or resynchronization.
The other options are incorrect for the following reasons:
Replacing all capacity devices with a similar larger device is incorrect because it will not increase the performance and will have a significant impact on the cluster. Replacing the capacity devices requires deleting the disk groups, which will erase all data on them and trigger a resynchronization of the affected objects. This can be disruptive and time-consuming, and also introduce additional network and disk traffic.
Replacing all cache devices with a larger device is incorrect because it will not increase the capacity and will have a significant impact on the cluster. Replacing the cache devices also requires deleting the disk groups, which will have the same drawbacks as replacing the capacity devices. Moreover, increasing the cache size may not improve the performance significantly, as vSAN OSA uses afixed cache ratio of
70% for write buffer and 30% for read cache, regardless of the cache device size.
Adding faster cache devices is incorrect because it will not increase the capacity and will have a significant impact on the cluster. Adding faster cache devices also requires deleting the disk groups, which will have the same drawbacks as replacing the cache devices. Furthermore, adding faster cache devices may not improve the performance significantly, as vSAN OSA uses a fixed cache ratio of 70% for write buffer and 30% for read cache, regardless of the cache device speed.

NEW QUESTION # 32
A vSAN administrator is noticing that the objects resynchronizing in the cluster are taking longer than expected and wants to view the resynchronizing metrics.
Which performance category should the vSAN administrator open?
- A. Host Network
- B. Resvnc Latency
- C. Disks
- D. Backend
Answer: D
Explanation:
Explanation
To view the resynchronizing metrics, the vSAN administrator should open the Backend performance category.
This category shows the performance of vSAN data components, such as read/write latency, IOPS, throughput, congestion, and resync traffic. The other categories are not relevant for this task. Disks shows the performance of physical disks in the cluster, Host Network shows the network performance of vSAN hosts, and Resvnc Latency shows the latency of resynchronization operations. References: 1, page 23; 3, section 6.4
NEW QUESTION # 33
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 AllPaths Down (APD) must be configured to Power off and restart VMs.
- 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 minimum of three nodes are required within the client cluster for vSphere HA to work
Answer: C,E
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 # 34
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. 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. - 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. 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. - D. 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.
Answer: C
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 # 35
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 updated policy is serially applied to the virtual machines.
- B. The changes are queued for 60 minutes.
- C. No changes occur until the policy is reapplied.
- D. The policy change is rejected immediately.
Answer: A
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 # 36
A vSAN administrator notices that the VMware Skyline Health: Network Latency Check reports indicate that three hosts are noncompliant.
Which action should the vSAN administrator take?
- A. Immediately reboot the non-compliant hosts
- B. Rerun the VMware Skyline Health: vSAN Cluster Partition report
- C. Check VMKNICs, uplinks, physical switches, and associated settings
- D. Place the non-compliant hosts into an isolated network partition
Answer: C
Explanation:
Explanation
The correct answer is B, check VMKNICs, uplinks, physical switches, and associated settings. This is because the VMware Skyline Health: Network Latency Check reports the network latency between vSAN hosts and displays the network latency in real time. Failure indicates that the network latency is above the normal threshold, which can affect the performance and availability of vSAN. The network latency can be caused by various factors, such as misconfiguration, congestion, or errors in the network components. The vSAN administrator should check the VMKNICs, uplinks, physical switches, and associated settings for any issues and resolve them accordingly. The vSAN administrator can also use tools such as vmkping or esxtop to test the network connectivity and performance between hosts. The other options are incorrect for the following reasons:
A, immediately reboot the non-compliant hosts, is incorrect because rebooting the non-compliant hosts is not a recommended action and can cause more disruption and data loss than resolving the network issue. Rebooting the hosts will also trigger a resynchronization of data across the cluster, which can affect the performance and availability of vSAN.
C, rerun the VMware Skyline Health: vSAN Cluster Partition report, is incorrect because rerunning the VMware Skyline Health: vSAN Cluster Partition report will not help to resolve the network latency issue. The vSAN Cluster Partition report checks if there are any network partitions in the cluster that prevent communication between hosts. The network partition can be caused by network latency, but it is not the same as network latency. The vSAN administrator should first fix the network latency issue before checking for any network partitions.
D, place the non-compliant hosts into an isolated network partition, is incorrect because placing the non-compliant hosts into an isolated network partition will not help to resolve the network latency issue.
It will also cause more problemsfor vSAN, such as data inconsistency, reduced redundancy, and degraded performance. The vSAN administrator should avoid creating any network partitions in the cluster and ensure that all hosts can communicate with each other. References:

NEW QUESTION # 37
A vSAN administrator needs to enable vSAN ESA.
Which two requirements need to be met? (Choose two.)
- A. vSAN ReadyNodes configuration
- B. vSAN Witness Appliance
- C. vSAN Standard license
- D. vSAN Build Your Own configuration
- E. vSAN Advanced license
Answer: A,C
Explanation:
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
NEW QUESTION # 38
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. RAID-6
- B. RA1D-1
- C. RAID-5
- D. RAID-0
Answer: B
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. References: RAID Configurations, FTT, and Host Requirements; RAID 5 or RAID 6 Design Considerations
NEW QUESTION # 39
A vSAN administrator has a group of requirements from the application team, which mandates spreading the components across storage devices as much as possible.
What should the vSAN Administrator consider to achieve such a requirement for building a new vSAN cluster? (Choose two.)
- A. Enable Force Provisioning in OSA
- B. Create a dedicated Storage Pool in ESA
- C. Configure disk striping in ESA
- D. Enable deduplication for vSAN
- E. Configure disk striping in OSA
Answer: D,E
Explanation:
Explanation
To spread the components across storage devices as much as possible, the vSAN administrator can configure disk striping in either OSA or ESA. Disk striping is a policy attribute that defines the number of capacity devices across which each replica of a storage object is striped. A higher number of stripes can result in better performance and availability, but also consumes more storage space. Disk striping can be configured in OSA by using the Number of disk stripes per object policy attribute, or in ESA by using the Striping Width policy attribute12 References: 1: VMware vSAN Specialist v2 Exam Preparation Guide, page 14 2: VMware vSAN Design and Sizing Guide, page 32
NEW QUESTION # 40
A vSAN administrator needs to update vSAN from version 7.0.2 to version 8.0.
Which is the correct order to perform the update?
- A. vCenter -> vSphere -> vSAN on-disk format
- B. vSphere -> vSAN on-disk format -> vCenter
- C. vSphere -> vCenter -> vSAN on-disk format
- D. vSAN on-disk format -> vSphere -> vCenter
Answer: A
Explanation:
Explanation
The correct order to perform the update from vSAN version 7.0.2 to version 8.0 is to upgrade the vCenter Server first, then upgrade the ESXi hosts, and finally upgrade the vSAN on-disk format. This order follows the general vSphere upgrade order, which ensures compatibility and interoperability between different components. Upgrading the vCenter Server first allows it to manage and monitor the ESXi hosts and the vSAN cluster during the upgrade process. Upgrading the ESXi hosts second ensures that they have the latest software patches and drivers for vSAN. Upgrading the vSAN on-disk format last enables the new features and functionality of vSAN 8.0. The other options are not correct, as they do not follow the recommended upgrade order.
NEW QUESTION # 41
An administrator has successfully deployed a vSAN Stretched Cluster and needs to ensure that any virtual machines that are created are placed in the appropriate site.
Which two steps are needed to complete this task? (Choose two.)
- A. Create a storage policy that includes site affinity rules and apply to VMs
- B. Create a single VM/Host group across both sites
- C. Create VM/Host groups for the two sites
- D. Put the VMs in a vSphere DRS group
- E. Put the VMs in the correct VM group
Answer: A,C
Explanation:
Explanation
To ensure that any virtual machines that are created are placed in the appropriate site, the administrator needs to create VM/Host groups for the two sites and create a storage policy that includes site affinity rules and apply to VMs. VM/Host groups allow the administrator to group virtual machines and hosts based on their location or preference. Site affinity rules specify which site a virtual machine should be placed on or prefer to run on. A single VM/Host group across both sites would not allow the administrator to control the placement of virtual machines. Putting the VMs in a vSphere DRS group or in the correct VM group would not affect their site affinity. References: 1, page 12; 2, section 3.2
NEW QUESTION # 42
A vSAN administrator receives a request from the application team to create a virtual machine on a vSAN datastore. The requirements state that the virtual machine needs to be available quickly after a failure occurs.
The solution must minimize administrative effort.
Which vSphere feature should the vSAN administrator implement?
- A. Distributed Services Engine
- B. vSphere High Availability
- C. vSphere Distributed Resource Scheduler
- D. Fault Tolerance
Answer: B
Explanation:
Explanation
vSphere High Availability is the correct answer because it meets the requirements of making the virtual machine available quickly after a failure occurs and minimizing administrative effort. vSphere HA monitors the health and availability of the hosts and virtual machines in a cluster and automatically restarts any failed virtual machines on other hosts within minutes. vSphere HA also supports proactive HA, which can migrate virtual machines from hosts that are about to fail or have degraded performance. vSphere HA is easy to configure and manage, as it only requires enabling HA on the cluster level and setting some basic policies and options. Distributed Services Engine,Fault Tolerance, and vSphere Distributed Resource Scheduler are not valid or optimal solutions for this scenario. Distributed Services Engine is a new feature in vSphere 7 that provides network services such as firewalling, load balancing, routing, and NAT for virtual machines and containers. It does not directly affect the availability or recovery of virtual machines after a failure. Fault Tolerance provides continuous availability for virtual machines by creating a secondary copy of the virtual machine that runs in lockstep with the primary copy on another host. If the primary copy fails, the secondary copy takes over without any interruption or data loss. However, Fault Tolerance has some limitations and overheads, such as requiring dedicated network bandwidth, supporting only one vCPU per virtual machine, and consuming twice as much CPU and memory resources as a single virtual machine. Fault Tolerance also requires more administrative effort than vSphere HA, as it needs to be enabled and configured for each individual virtual machine. vSphere Distributed Resource Scheduler is a feature that balances the workload and resources across a cluster by automatically migrating virtual machines based on their demand and priority.
It does not directly affect the availability or recovery of virtual machines after a failure, although it can work together with vSphere HA to find optimal hosts for restarting failed virtual machines. References:

NEW QUESTION # 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. Deploy the application on a new cluster with vSAN 8.0 OSA using the existing hybrid configuration
- B. Deploy the new applications on the existing cluster with a RAID-6 VM storage policy and an additional stripe width of 4
- C. Deploy the application on a new cluster with vSAN 8.0 ESA using a new hardware design
- D. Perform an in-place upgrade from vSAN 7.0 U2 OSA to vSAN 8.0 ESA
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 # 44
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. Isolate vSAN traffic in a VLAN
- D. Use IOPS Limit rules in storaqe policies
- E. Enable jumbo frames
Answer: A,C
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 # 45
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.
Answer: B
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.

vSAN requires that the virtual machines deployed on the vSAN datastores are assigned at least one storage policy, but the administrator did not explicitly assign a storage policy when provisioning the new VM.
What is the result of this situation?
- A. No data protection will be applied to the VM objects.
- B. The VM objects will be protected based on the vSAN Default Storage Policy configurations.
- C. The VM provisioning will fail.
- D. The vSphere Web Client will choose the last vSAN Storage Policy used.
Answer: B
Explanation:
Explanation
If the administrator did not explicitly assign a storage policy when provisioning a new VM on a vSAN datastore, the result is that the VM objects will be protected based on the vSAN Default Storage Policy configurations. The vSAN Default Storage Policy is assigned to all VM objects if no other vSAN policy is assigned when provisioning a VM. The default policy contains vSAN rule sets and a set of basic storage capabilities, such as Failures to tolerate set to 1, Number of disk stripes per object set to 1, and Thin provisioning. The other options are not correct. The VM provisioning will not fail, as vSAN requires that every VM has at least one storage policy. The vSphere Web Client will not choose the last vSAN Storage Policy used, as it will always apply the default policy if no other policy is selected. No data protection will not be applied to the VM objects, as they will have at least one replica based on the default policy.

NEW QUESTION # 47
A vSAN administrator is responsible for managing a customer's production vSAN cluster that is going to be used to provide SMB file shares to a number of host clients. The vSAN administrator must take action so the performance of all services in the production vSAN cluster can be monitored.
Which two services must be enabled for this monitoring to occur? (Choose two.)
- A. vSAN Health Service
- B. vSAN File Services
- C. vSAN Performance Service
- D. iSCSI Target Service
- E. vSAN Performance Diagnostic Service
Answer: B,C
Explanation:
Explanation
To monitor the performance of vSAN File Services, the vSAN administrator must enable both the vSAN File Services and the vSAN Performance Service. The vSAN File Services provides SMB file shares to host clients, while the vSAN Performance Service collects and analyzes performance statistics and displays them in the vSphere Client. The other services are not related to vSAN File Services performance monitoring.

NEW QUESTION # 48
An administrator wants to assign a storage policy to a workload on a two-node vSAN OSA cluster consisting of three disk groups each with nested fault domains. The virtual machine must be protected against a disk or disk group failure.
Which two storage policies meet these requirements? (Choose two.)
- A. RAID-1/FTT 1
- B. RAID-5/FTT 2
- C. RAID-1/FTT 3
- D. RAID-5/FTT 1
- E. RAID-6/FTT 2
Answer: A,E
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 # 49
A vSAN administrator has an existing cluster where each ESXi host has the following:
Disk group #1 with one cache device and three capacity devices.
Disk group #2 with one cache device and two capacity devices.
What must the vSAN administrator do to expand disk group #2 to have three capacity devices?
- A. Put the disk group in maintenance mode, evacuate all data, then add the new capacity device
- B. Add the new capacity device to the disk group and vSAN will automatically rebalance
- C. Put the entire ESXi host in maintenance mode, evacuate all data, then add the new capacity device
- D. Create a new disk group with a single capacity device and then migrate the existing capacity devices
Answer: B
Explanation:
Explanation
To expand disk group #2 to have three capacity devices, the vSAN administrator should add the new capacity device to the disk group and vSAN will automatically rebalance. This action allows the administrator to increase the storage capacity of the disk group without disrupting any ongoing operations or evacuating any data. vSAN will automatically distribute data across all devices in the disk group to balance performance and utilization. The other options are not correct. Creating a new disk group with a single capacity device and then migrating the existing capacity devices is not necessary, as it would require more steps and resources than adding a device to an existing disk group. Putting the entire ESXi host or the disk group in maintenance mode and evacuating all data is not required, as it would cause downtime and data movement that could be avoided by adding a device to an existing disk group.

NEW QUESTION # 50
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. Delete all device partitions
- B. Create a 1GB metadata partition
- C. Create a VMFS partition
- D. Format the existing partition
Answer: A
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.
