During a vSAN design workshop, a customer expressed a requirement to decommission an existing enterprise NAS device that provides iSCSI services for a clustered application.
Based on the current state analysis, the following information was noted:
* Current utilization is 500 LUNs.
* All clustered workloads are configured for Multiple Connections per Session.
* LUN sizes range between 10 TB to 30 TB.
What should the architect state regarding the requirements?

A 4-node vSAN cluster is configured with an erasure coding storage policy. The Ensure Accessibility maintenance mode was selected. While performing the maintenance, a second node fails.
What will be the impact on the vSAN cluster?
An administrator managing a vSAN cluster of six-nodes with policy FTT-2/RAID-6 decided to put one of the nodes in maintenance mode using the ''Full-data migration'' option.
What will happen after this action is taken?
https://blogs.vmware.com/virtualblocks/2020/02/06/what-happens-vsan-host-in-maintenance-mode/ Let's take a look at a few unique scenarios with regard to maintenance mode. First, let's see what will happen if you have 6 hosts within your cluster, you have applied a policy containing FTT=2/RAID-6, and you want to place a host in maintenance mode using the 'Full data migration' option. This means all the data residing on the host will be evacuated to another host within the cluster. With this type of data configuration, the system will prompt you to add an additional host to the cluster in order to preserve the policy compliance. The policy will always require there must be two failures that can be tolerated, even during cluster reduction due to maintenance mode removing a host. Note that a minimum of six hosts is required to support a storage policy with RAID-6(FTT=2) erasure coding
An administrator is troubleshooting vSAN performance issues, and the performance diagnostics reports:
"There are errors seen in one or more physical NICs on one or more hosts."
Which two problems must be resolved to fix this issue? (Choose two.)

In a vSAN stretched cluster, which value must be set in the vSAN policy if there is no requirement for data mirroring across sites?
PFTT can be seen as ''site failures'', and you can always only tolerate 1 at most. SFTT can be seen as host failures, and you can define this between 0 and 3 https://www.yellow-bricks.com/2018/03/19/vsan-stretched-cluster-pftt-and-sftt-what-happens-when-a-full-site-fails-and-multiple-hosts-fail/
