VMware 5V0-22.21 Dumps

The correct answers are D. Login on MyVMware, and download the vSphere and vSAN software bundles and E. Verify the supportability of the software, hardware, drivers, firmware, and storage I/O controllers on the VMware Compatibility Guide. Before upgrading the vSAN cluster, the administrator should first login to MyVMware and download the vSphere and vSAN software bundles, and then verify the supportability of the software, hardware, drivers, firmware, and storage I/O controllers on the VMware Compatibility Guide. Once the compatibility has been verified, the administrator can proceed with disabling vSphere DRS and vSphere HA in order to avoid VMs and data from moving among the nodes during the vSAN upgrade process, and then put the host in maintenance mode with "Ensure Accessibility".

vLCM enhances the remediation operation in this situation by allowing the administrator to remediate all remote sites and the main campus concurrently. This allows for faster remediation and reduces the amount of time and effort required by the administrator. The other choices are incorrect, as vLCM can remediate all clusters concurrently, vSphere Update Manager (VUM) cannot be used to remediate the main campus, and vLCM cannot remediate the clusters one-by-one in a parallel manner.

To verify object resynchronization progress and impact after a global policy change, you can use vRealize Log Insight (C). According to the VMware Official Guide, “The vRealize Log Insight dashboard can be used to verify object resynchronization progress and impact after a global policy change.”

According to VMware's documentation, the "No Data Migration" option for maintenance mode should be used when the expected maintenance time is less than one hour. This option will allow the administrator to complete their maintenance without having to wait for a full data migration, which can be time consuming and also has additional capacity and performance considerations. It is important to note that this option will not guarantee the same level of availability as the other options, so it should only be used when the expected maintenance time is less than one hour.

An all-flash vSAN cluster contains a sufficient number of capacity devices and cache devices to support different RAID levels.

FTT=3(RAID-1 Mirroring) - This policy requires at least 4 capacity devices, where each object is mirrored across three copies of the object. This can be satisfied by the 4 nodes all-flash vSAN cluster.

FTT=1 (RAID-1 Mirroring) - This policy requires at least 2 capacity devices, where each object is mirrored across one copy of the object. This can be satisfied by the 4 nodes all-flash vSAN cluster.

FTT=2 (RAID-6 Erasure Coding) - This policy requires at least 6 capacity devices, where each object is striped across two sets of parity and data. This cannot be satisfied by the 4 nodes all-flash vSAN cluster.

FTT=1 (RAID-5 Erasure Coding) - vSAN does not support RAID-5 Erasure coding.

PowerCLI is a command-line interface for managing VMware vSphere, vSAN and other VMware products. RVC is the Ruby vSphere Console which is an interactive command-line tool for managing vSphere, vSAN, and other VMware products. Using PowerCLI and RVC, you can run commands to identify unassociated objects and take corrective action. For example, you can use PowerCLI to list all vSAN objects and RVC to perform a check on the objects to see if they are unassociated.

When upgrading existing vSAN hosts with multiple SSD cache devices per host to NVMe devices, it is important to note that the disk group does not need to be removed before adding new cache. NVMe devices can be hot-plugged into the host, and vSAN will automatically detect and use the new devices as cache. It is important to check if the NVMe devices are supported by your version of vSAN and also check that the NVMe devices are on the VMware HCL.

This is explained in VMware vSAN documentation in the section "Upgrading vSAN Hardware" Reference:

The maximum time range that can be stored by the vSAN health check history is 180 days (C). According to the VMware Official Guide, “The vSAN Health Check history is stored for up to 180 days before it is automatically purged.”

vsantop is a command line utility that can be used to monitor the performance of a vSAN cluster in real-time. It provides detailed information about the performance of the vSAN cluster and its components, including disk usage, IOPS, network traffic, and object states. It can be used to identify the root cause of performance problems, such as disk contention, network congestion, or object failures. It provides a quick and easy way to identify the root cause of performance issues, making it a useful tool for troubleshooting vSAN clusters.

This is explained in VMware vSAN documentation in the section "vSAN Tools and Troubleshooting" Reference:

This is because vSAN maintains a copy of the object on each host that is a member of the vSAN cluster. When a host enters maintenance mode, the object's replica is moved to another host in the cluster. If another host in the cluster fails during this time, it's possible that the updated replica of an object may be lost. However, vSAN will still use the stale replica of the object on the host that exited maintenance mode to service read requests, and will update the stale replica with the latest writes from the remaining host after the host exits maintenance mode.

It is important to note that this scenario assumes that the host failure is a permanent failure and that vSAN does not have any additional data protection methods enabled such as RAID-5, RAID-6, or Erasure Coding.

The correct answer is D. The latest writes from Host-2 are applied to the stale components of Host-1 once the host exits maintenance mode. This is because vSAN utilizes a "write-order fidelity" mechanism which ensures that any writes that were committed to the other hosts in the cluster before Host-1 entered maintenance mode are applied to the stale components of Host-1 as soon as the host exits maintenance mode. Reference:

C. Enter Maintenance Mode, confirm that pre check is fine, select "Full data migration", "Shutdown ESXi host", replace all capacity devices, "Restart ESXi host", replace capacity devices in disk groups, exit Maintenance Mode, confirm that raw capacity has been increased, and then repeat on ESXi host one-by-one. D. "Shutdown ESXi host", and replace all capacity devices. Repeat this sequence one-by-one.

Option C would allow you to perform a full data migration, which will move all data from the old capacity device to other devices. This option allows for the vSAN cluster to remain offline during the replacement process, and it allows the vSAN administrator to replace all the capacity devices at once.

Option D would also allow you to replace all capacity devices at once, however, the data is not moved from the old capacity device to other devices, this option also allows for the vSAN cluster to remain offline during the replacement process and it allows the vSAN administrator to replace all the capacity devices at once.

You can find more information on adding capacity to a vSAN cluster in the vSphere 7.0 documentation: and also in VMware blog like:

The two approaches the vSAN administrator can use to complete this task are C. Enter Maintenance Mode, confirm that pre check is fine, select "Full data migration", "Shutdown ESXi host", replace all capacity devices, "Restart ESXi host", replace capacity devices in disk groups, exit Maintenance Mode, confirm that raw capacity has been increased, and then repeat on ESXi host one-by-one and D. "Shutdown ESXi host", and replace all capacity devices. Repeat this sequence one-by-one. Reference:

The vSAN administrator must perform an immediate upgrade of the on-disk format. This status indicates that the vSAN on-disk format version is lower than the expected version. This could be caused by an incompatible version of the vSAN software or may be due to a failed upgrade attempt. In order to address this issue, the vSAN administrator must perform an immediate upgrade of the on-disk format. Reference:
