Question11: Which three statements are true regarding vSAN networking requirements? (Choose three.)

Question12: With the addition of local protection to vSAN stretched clusters, which factors determine the maximum level of object protection?

Question13: 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 nodes are NOT affected by the network failure.
How does this network failure impact VM01?

Question14: When using RAID-5 with a 100GB virtual disk, what is the maximum capacity consumed on the vSAN datastore for this virtual disk?

Question18: What is the minimum number of components that comprise a 100GB vSAN object with a RAID-5 erasure coding policy assigned to it?

Question19: Which storage policy is automatically created by Horizon View?

Question20: How does vSAN respond when a vSAN drive is pulled from a server chassis or a host if a vSAN cluster fails without warning?

Question21: 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?

Question22: If a vSAN capacity device experiences a pattern of sustained high latency, how does vSAN attempt to remediate the issue?

Question23: In a vSAN stretched cluster with Primary level to tolerate set to 1 and Secondary level of failure to tolerate set to 2, what is the maximum amount of space that a 100GB virtual disk could consume without any other policy rules set?

Question24: Which three sources can be queried to retrieve storage policy components? (Choose three.)

Question25: Which two requirements must be satisfied for a v object protected by a RAID-1 mirroring policy to be accessible? (Choose two.)

Question26: vSAN supports Microsoft Windows Server Failover Cluster (WSFC) with which configuration?

Question27: Which vSAN health check category is viewed to confirm supported storage controller drivers are in use across all hosts in the cluster?

Question28: Which two vSAN configurations require the use of a witness appliance? (Choose two.)

Question29: An administrator is deploying vSAN 6.6.
What must the administrator configure to set up vSAN networking?

Question30: Which statement is true about two-node vSAN cluster configuration?

Question31: What are three fundamental concepts of vSAN clusters? (Choose three.)

Question32: Which three objects that belong to virtual machines are contained in a vSAN datastore? (Choose three.)

Question33: 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?

Question34: Which statement the describes vSAN architecture?

Question35: The vSAN health check is showing alarms for network partitioning. All hosts in the cluster are configured with a VMkernel port?
What are two possible causes for this alarm? (Choose two.)

Question36: Which statement is true about the deduplication and compression feature in vSAN?

Question37: What are two ways to examine the storage policy compliance of a virtual machine? (Choose two.)

Question38: A six-node all-flash vSAN cluster has been deployed. Deduplication and compression are enabled. All virtual machines are produced by policies with the rule Primary level of failures to tolerate set to 1.
How is a vSAN disk group impacted when the cache device belonging to that disk group fails?

Question39: An administrator is designing a vSAN cluster for a number of new workloads. The design calls for the use of erasure coding with RAID 5.
Which statement is true about what is needed to meet the needs of this scenario?

Question40: Which two factors below determine how a VMDK object will be split on a vSAN cluster? (Choose two.)

Question41: Which format for desktops does vSAN support?

Question42: What is required for enabling deduplication and compression in a vSAN cluster?

Question43: An administrator has configured a storage policy with a Primary level of failures to tolerate set to 3 and assigned this policy to a virtual disk.
What is the minimum number of hosts required in this vSAN cluster?

Each host has 16.8TB of raw capacity and the three-node cluster has 50.4TB of raw capacity.
