After a server power failure, the administrator noticed the scheduled resyncing in the cluster monitor displays objects to be resynchronized under the pending category.
What are these objects in this category?
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.
The objects on a 4-node vSAN cluster are assigned a RAID-5 policy. A network outage occurs, causing host one to lose connectivity with the rest of the cluster. Seventy-five minutes have elapsed.
What is the health state of the objects?
Minimum number of hosts required for Raid 5: 2n+1.
Reduced availability - active rebuild: The object has suffered a failure, but it was configured to be able to tolerate the failure. I/O continues to flow and the object is accessible. vSAN is actively working on re-protecting the object by rebuilding new components to bring the object back to compliance.
Reduced availability with no rebuild: The object has suffered a failure, but VSAN was able to tolerate it. For example: I/O is flowing and the object is accessible. However, VSAN is not working on re-protecting the object. This is not due to the delay timer (reduced availability - no rebuild - delay timer) but due to other reasons. This could be because there are not enough resources in the cluster, or this could be because there were not enough resources in the past, or there was a failure to re-protect in the past and VSAN has yet to retry.
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.)
According to VMware's official guide, Network I/O Control (NIOC) should be utilized in order to share the physical adapters' capacity among several traffic types. Additionally, isolating the vSAN traffic in a VLAN will provide enhanced security, as it isolates vSAN traffic from the rest of the network traffic. Enabling jumbo frames and creating static routes between the vSAN hosts will not provide the desired result, as these are not related to the requirements. Utilizing IOPS Limit rules in storage policies is also not related to the requirements, as this is related to storage policies and not network configuration.

A vSAN administrator has three available racks and six vSAN hosts and needs to protect against a rack failure while maximizing resources.
Which two strategies should the vSAN administrator use to achieve this goal? (Choose two.)
