質問 # 41
After a planned power outage, an administrator decided to restart the vSAN cluster manually.
What is the correct sequence of steps for the administrator to follow after powering on the ESXi hosts?

  • A. 1. Exit all hosts from maintenance mode.
    2. Enable cluster member updates from vCenter Server only on one ESXi host.
    3. Run the python reboot helper script only on one ESXi host to recover the cluster.
  • B. 1. Enable cluster member updates from vCenter Server on all ESXi hosts.
    2. Run the python reboot helper script on all ESXi hosts to recover the cluster.
    3. Exit all hosts from maintenance mode.
  • C. 1. Exit all hosts from maintenance mode.
    2. Run the python reboot helper script only on one ESXi host to recover the cluster.
    3. Enable cluster member updates from vCenter Server on all ESXi hosts.
  • D. 1. Enable cluster member updates from vCenter Server only on one ESXi host.
    2. Run the python reboot helper script only on one ESXi host to recover the cluster.
    3. Exit all hosts from maintenance mode.

正解:D

解説:
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.

質問 # 42
What are two characteristics of a durability component in vSAN? (Choose two.)

  • A. Faster resynchronization
  • B. Better Performance
  • C. Faster snapshot creation
  • D. Better Storage utilization
  • E. Better Availability

正解:A、E

解説:
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. References: VMware vSAN Specialist v2 EXAM 5V0-22.23, page
10, Objective 6.8; [Durability Components]


質問 # 43
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"

正解:B

解説:
Explanation
To reduce the amount of vSAN datastore capacity the virtual machines will consume, the vSAN administrator should change the FTT rule to "1 Failure - RAID-1 (Mirroring)", and select "Now" for Reapply to VMs. This action will reduce the number of replicas for each object from three to two, and thus free up some space on the vSAN datastore. The other options are not correct, as they will not reduce the capacity consumption.
Modifying the FTT rule to "2 Failures - RAID-5 (Erasure Coding)" will not work for a hybrid vSAN cluster, as erasure coding is only supported for all-flash clusters. Adding the "Flash read cache reservation" rule to the storage policy, and setting to 0% will not affect the capacity layer, as it only controls the amount of flash cache reserved for each object. Disabling Operations reserve and Host rebuild reserve and clicking "Apply" will not change the actual space used by the objects, as these reserves are only logicalsettings that affect how much free space is reported by vSAN. References: 1, page 9; , section 4.3


質問 # 44
An administrator is responsible for managing a five-node vSAN cluster. The vSAN Cluster is configured with both vSphere High Availability (HA) and vSphere Distributed Resource Scheduler (DRS). The vSAN Cluster is currently hosting 150 virtual machines that have consumed 60% of the usable capacity.
Each virtual machine belongs to one of the following vSAN Storage Policies:
vSANPolicy1:
Site Disaster Tolerance: None
Failures to Tolerate: 1 failure - RAID-5 (Erasure Coding)
vSANPolicy2:
Site Disaster Tolerance: None
Failures to Tolerate: No data redundancy
Following an unplanned power event within the data center, the administrator has been alerted to the fact that one host has permanently failed.
What will be the impact to any virtual machine that was running on the failed host using vSANPolicy1?

  • A. Each virtual machine will be unavailable for up to 90 minutes while the automatic recovery process completes.
  • B. Each virtual machine must be restored from backup.
  • C. 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.
  • D. Each virtual machine will be restarted on another vSAN host usingvSphere HA.

正解:D

解説:
Explanation
The impact to any virtual machine that was running on the failed host using vSANPolicy1 is that each virtual machine will be restarted on another vSAN host using vSphere HA. This is because vSANPolicy1 has a Failures to Tolerate setting of 1 failure - RAID-5 (Erasure Coding), which means that each object has four components (three data and one parity) distributed across four hosts. If one host fails, the object can still be accessed with the remaining three components,and vSphere HA will restart the virtual machine on another host. vSAN will also try to rebuild the missing component on another host, if there is enough capacity and resources. The other options are incorrect because they either assume that the object is unavailable or that the recovery process is delayed or impossible.

質問 # 45
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 Performance Service
  • B. vSAN Performance Diagnostic Service
  • C. iSCSI Target Service
  • D. vSAN Health Service
  • E. vSAN File Services

正解:A、E

解説:
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.

質問 # 46
An administrator is deploying a new two-node vSAN cluster with a shared witness to a remote location.
Which requirement must be met?

  • A. The ESXi host's drives must be configured in RAID 1 to support Failures to Tolerate of 1.
  • B. The ESXi host's controller cache and advanced features must be disabled.
  • C. The ESXi hosts must have a minimum of 64 GBs of memory.
  • D. The ESXi hosts must have SSDs or NVMe configured for Virtual Flash File System.

正解:C

解説:
Explanation
To deploy a new two-node vSAN cluster with a shared witness, the administrator must meet several requirements, one of which is that the ESXi hosts must have a minimum of 64 GBs of memory. This is because each host must have enough memory to run the VMs and also to support the vSAN metadata overhead. The other options are not requirements for a two-node vSAN cluster with a shared witness. The ESXi hosts do not need SSDs or NVMe for Virtual Flash File System, as they can use any supported storage devices for vSAN. The ESXi host's controller cache and advanced features do not need to be disabled, as they can be used to improve performance and reliability. The ESXi host's drives do not need to be configured in RAID 1, as vSAN uses its own software-defined RAID mechanism to provide Failures to Tolerate.

質問 # 47
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. If vSphere HA is to work with HCI Mesh, Datastore with AllPaths Down (APD) must be configured to Power off and restart VMs.
  • C. If vSphere HA is to work with HCI Mesh, Datastore with Permanent Device Loss (PDL) must be confiqured to Power off and restart VMs.
  • D. A minimum of three nodes are required within the client cluster for vSphere HA to work
  • E. A server vSAN cluster can serve its local datastore up to five client vSAN clusters.

正解:B、D

解説:
Explanation
To design a HCI Mesh solution with VMware vSAN and VMware vSphere High Availability (HA), two considerations that the architect should assess are: A minimum of three nodes are required within the client cluster for vSphere HA to work. This is because vSphere HA needs at least three nodes in a cluster to form a quorum and elect a master host that monitors the availability of other hosts and VMs. If there are less than three nodes in a cluster, vSphere HA cannot function properly and might fail to detect or respond to host or VM failures. If vSphere HA is to work with HCI Mesh, Datastore with All Paths Down (APD) must be configured to Power off and restart VMs. This is because APD is a condition that occurs when a storage device becomes inaccessible due to loss of physical connectivity, resulting in I/O errors or timeouts for VMs that use that device. When using HCI Mesh, APD can happen if the network connection between the client cluster and the server cluster is lost or disrupted, causing the remote datastore to become unavailable. To ensure that vSphere HA can restart the affected VMs on another host that has access to their storage, Datastore with APD must be set to Power off and restart VMs in the vSphere HA settings. The other options are not correct. A server vSAN cluster can serve its local datastore up to 15 client vSAN clusters, not five. This is the maximum number of client clusters that can mount a remote datastore from a server cluster using HCI Mesh.
A client cluster can mount up to five remote datastores from one or more vSAN server clusters, not ten. This is the maximum number of remote datastores that can be mounted by a client cluster using HCI Mesh.

質問 # 48
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. vSphere High Availability
  • B. Fault Tolerance
  • C. Distributed Services Engine
  • D. vSphere Distributed Resource Scheduler

正解:A

解説:
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:

質問 # 49
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. Put the VMs in a vSphere DRS group
  • C. Create VM/Host groups for the two sites
  • D. Put the VMs in the correct VM group
  • E. Create a single VM/Host group across both sites

正解:A、C

解説:
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


質問 # 50
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. Erasure Coding is disabled in the storage policy.
  • B. The Virtual Machines are using PVSCSI controllers.
  • C. There is congestion in one or more disk groups.
  • D. Jumbo frames are not enabled on the VMkernel adapters.

正解:C

解説:
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]


質問 # 51
A vSAN administrator has a vSAN cluster that is using vSphere Lifecycle Manager (vLCM) to manage hypervisor, server drivers, and firmware. All hosts in the cluster are compliant according to the vLCM image.
A 10GB NIC on the servers is experiencing issues, and the vSAN administrator determines a new network driver will resolve the problem. Unfortunately, the required NIC driver is a newer version compared to the driver provided by the most recent Vendor Add-on.
Which action should the vSAN administrator take to ensure the latest network driver is installed on the NIC before remediation?

  • A. Add an individual component to the vLCM image that has the updated NIC driver
  • B. Make sure the vLCM image is configured to use the most recent version of the Vendor Add-on
  • C. Remove theVendor Add-on from the vLCM image, and then manually install the network driver on the servers
  • D. Modify the vLCM image to omit the NIC Driver, and then manually update the servers with the required NIC driver

正解:A

解説:
Explanation
To ensure the latest network driver is installed on the NIC before remediation, the vSAN administrator should add an individual component to the vLCM image that has the updated NIC driver. This action allows the administrator to override the driver provided by the vendor add-on and use a newer version that is compatible with the ESXi version and the hardware device. The administrator can add an individual component to the vLCM image by importing it from a ZIP file or selecting it from the vLCM depot. The other options are not correct. Making sure the vLCM image is configured to use the most recent version of the vendor add-on will not help, as the required NIC driver is a newer version than the one provided by the vendor add-on. Removing the vendor add-on from the vLCM image or modifying the vLCM image to omit the NIC driver will not ensure the latest network driver is installed on the NIC, as these actions will leave the NIC without any driver update. Manually installing or updating the network driver on the servers is not recommended, as it might cause inconsistency and non-compliance in the vLCM image.

質問 # 52
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. Some VM data will be unavailable until the failed ESXi host is recovered
  • C. The data components on the hosts will be marked as degraded
  • D. vSAN can protect the platform using adaptive RAID 5 if the ESXi host fails to return

正解:C

解説:
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


質問 # 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 Replication
  • B. vSAN Stretched Clusters
  • C. vSAN File Services
  • D. vSAN HCI Mesh

正解:D

解説:
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


質問 # 54
Due to a planned power outage, an administrator decides to shut down the vSAN cluster using the Shutdown Cluster Wizard. The administrator starts by checking the vSAN health service to confirm the cluster is healthy and then powers off all virtual machines (VMs) including vCLS VMs.
Which step needs to be taken before starting the Shutdown Cluster Wizard?

  • A. Shutdown vCenter
  • B. Place all ESXi hosts into maintenance mode
  • C. Disable cluster member updates from vCenter Server
  • D. Turn off High Availability

正解:D

解説:
Explanation
To shut down the vSAN cluster using the Shutdown Cluster Wizard, the administrator needs to turn off High Availability (HA) before starting the wizard. This is because HA monitors the cluster for host failures and attempts to restart the affected VMs on other hosts. If HA is not turned off, the cluster might register host shutdowns as failures and trigger unnecessary VM restarts, which can interfere with the graceful shutdown process. Therefore, the administrator should disable HA from the Configure tab of the cluster before using the Shutdown Cluster Wizard12 References: 1: Shut Down the vSAN Cluster Using the Shutdown Cluster Wizard 3 2: Manually Shut Down and Restart the vSAN Cluster 4


質問 # 55
A customer wants to validate if Skyline online health is working for vSAN and finds out that Skyline is not fully configured yet.
What two requirements must be met to make sure that Skyline online health will work? (Choose two.)

  • A. Enable Skyline Health on the vSAN Cluster
  • B. Have vCenter on version 7 or higher
  • C. Have a working Internet connection
  • D. Enable CEIP and join the program
  • E. Add the Skyline license into Virtual Center

正解:C、D

解説:
Explanation
To make sure that Skyline online health will work for vSAN, two requirements must be met: enable CEIP and join the program, and have a working Internet connection. CEIP stands for Customer Experience Improvement Program, which is a voluntary program that collects anonymous product usage data from customers who participate in it. By enabling CEIP and joining the program, customers can benefit from Skyline online health, which provides proactivenotifications and recommendations for software and hardware issues based on VMware Analytics Cloud. A working Internet connection is also required for Skyline online health to communicate with VMware Analytics Cloud and receive online notifications. The other options are not requirements for Skyline online health. References: About the vSAN Skyline Health; Skyline Health


質問 # 56
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. 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
  • B. Physically replace the failed cache device, and vSAN will automatically allocate the storage. Then, rebalance the cache layer.
  • C. Physically replace the failed cache device, and vSAN will automatically create a new disk group. Then, remove the disk group with the failed device.

正解:B

解説:
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
