An administrator is responsible for managing a 5-node vSAN 7.0 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 - RAID5 (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 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?

A.
Assign a new policy with "Failures to tolerate" set to "1-Failure - RAID-5 (Erasure Coding)" to the virtual machines.
Answers
A.
Assign a new policy with "Failures to tolerate" set to "1-Failure - RAID-5 (Erasure Coding)" to the virtual machines.
B.
Assign a policy with "Object space reservation" set to "50%" to the virtual machines.
Answers
B.
Assign a policy with "Object space reservation" set to "50%" to the virtual machines.
C.
Reduce the "Number of disk stripes per object" from 3 to 2 in the vSAN Default Storage Policy.
Answers
C.
Reduce the "Number of disk stripes per object" from 3 to 2 in the vSAN Default Storage Policy.
D.
Set "Failures to tolerate" in the vSAN Default Storage Policy to "2-Failures - RAID-1 (Mirroring)".
Answers
D.
Set "Failures to tolerate" in the vSAN Default Storage Policy to "2-Failures - RAID-1 (Mirroring)".
Suggested answer: B

Explanation:

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.

This is explained in VMware vSAN documentation in the section "vSAN Storage Policy" Reference:
