Question12: When using vSAN in a two-node direct connect configuration, how do data nodes communicate with the vSAN witness appliance?

Question13: Which statement describes vSAN architecture?

Question14: What must be enabled for the vSAN online health feature to function?

Question15: Consider the following scenario in a vSAN cluster that contains six hosts:
All virtual machines are assigned the vSAN Default Storage Policy, which has not been modified.

Deduplication and compression are not enabled.

Every vSAN disk group in the cluster contains one cache device and five capacity devices

What happens when a capacity devices transmits SCSI sense code errors and fails?

Question20: Which statement is true about the deduplication and compression feature in vSAN?

Question21: Exhibit:

View the exhibit.
The following are configuration details for a three-node all-flash vSAN cluster Each node is identical in number of drives and disk controllers

Each node has 4 x 500 GB SSD Capacity Tier, 1 x 200 GB SSD cache tier

What is the raw capacity of this cluster as configured?

Question22: An administrator is designing a new vSphere cluster with vSAN enabled that will span four racks with multiple hosts per rack. The requirement is to provide recoverability during a rack outage.
What needs to be done to meet this requirement?

Question23: A virtual machine named VM01 is running on Host01 on a four-node vSAN cluster. vSphere HA is enabled for the cluster. vSphere HA host isolation response is set to Power off and restart VMs. VM01 has a storage policy assigned to it that contains the rule Primary level of failures to tolerate = 1.
A network failure occurs that causes a vSAN network partition. Host01 is isolated from the rest of the cluster. The other three nores are NOT affected by the network failure.
How does this network failure impact VM01?

Question24: What are IOPS?

Question25: What is required when enabling deduplication and compression in a vSAN cluster?

Question26: A 12-node vSAN cluster has been deployed across three server racks in a data center.
There are four nodes in each server rack.

A vSAN fault domain has been configured for each server rack for a total of three fault domains.

All virtual machines in the cluster have the vSAN default storage policy assigned to them.

This policy has not been modified.

vSphere HA is enabled for the cluster.

One of the server racks loses power.

How does this affect virtual machines running on this cluster?

Question27: View the exhibit.
The exhibit shows a single node of a vSAN cluster. All nodes have been configured identically.
Which statement is true about the exhibit?

Question28: If the Primary level of failures to tolerate policy is changed from 2 to 3 without shutting down the virtual machine, what will happen when the policy is applied?

Question29: In order to support Oracle Real Application Cluster (RAC), which change must be made to each applicable virtual machine?

Question30: Which two VM Storage Policy rules are supported with vSAN iSCSI Target LUNs? (Choose two.)

Question31: With the addition of local protection to vSAN stretched clusters, which factors determine the maximum level of object protection?

Question32: vSAN supports Microsoft Windows Server Failover Cluster (WSFC) with which configuration?

Question33: How many consecutive heartbeats of communication must be lost between master and the witness host for the witness host to be deemed to have failed?

Question34: Consider the following vSAN host configuration:
Each host contains one vSAN disk group

All drives in the vSAN disk group are attached to the same storage controller

All virtual machines are assigned the Virtual SAN Default Storage Policy, which has not been modified

ESXi is installed on and running from a drive connected connected to a separate storage controller

vSphere HA is enabled

What happens when the storage controller with the vSAN drives attached fails?

Question35: A cache tier device experiences a permanent disk failure.
