A vSAN storage policy with the 'Failures lo Tolerate" rule set to "2 failures - RA1D-1 {Mirroring)" is assigned to multiple virtual machines.
The vSAN administrator is considering assigning a new vSAN storage policy with the "Failures to Tolerate' rule set lo '2 failures - RAID-6* (Erasure Coding)" to the virtual machines.
How will the capacity of the vSAN datastore be affected if this action is taken?
Used capacity will increase temporarily while the erasure coded components are built. When a vSAN storage policy with 'Failures to Tolerate' set to '2 failures - RAID-6 (Erasure Coding)' is assigned to multiple virtual machines, the components of the objects stored on the vSAN datastore will be rebuilt in an erasure coding format, which requires additional capacity. This additional capacity will be used temporarily while the erasure coded components are built, and will be reclaimed once the process is complete.

According to the VMware vSAN documentation, when a vSAN storage policy with 'Failures to Tolerate' set to '2 failures - RAID-6 (Erasure Coding)' is assigned to multiple virtual machines, the components of the objects stored on the vSAN datastore will be rebuilt in an erasure coding format, which requires additional capacity. This additional capacity will be used temporarily while the erasure coded components are built, and will be reclaimed once the process is complete.
A group of virtual machines have the vSAN Default Storage Policy assigned to them. This policy has not been modified from its default settings to date. The vSAN administrator would like to reduce the amount of storage capacity consumed by these virtual machines.
Which action will produce this result?
Object space reservation is a vSAN storage policy attribute that allows the administrator to set a percentage of the provisioned space to be reserved for the virtual machine disk objects. This attribute can be used to reduce the amount of storage capacity consumed by virtual machines. Setting the 'Object space reservation' to '50%' will reserve 50% of the total provisioned space for the virtual machines, and free up the remaining 50% for other objects.
It's worth noting that changing object space reservation can result in a component resync, which could cause a performance impact.
What os the maximum number of 2-node clusters that can share a vSAN Shared Witness host in vSAN 7.0 U1?
The Resyncing Objects view in the vCenter UI reports that some objects are currently resyncing.
Which two actions would cause this situation? (Choose two.)
While preparing to update a vSAN cluster, an administrator finds that the firmware revision of the onboard storage controllers is no longer listed as supported in the Hardware Compatibility Guide, but new firmware is available.
Which action should the administrator take upon discovering this piece of information?
