A single disk in a vSAN disk group suffers from an unrecoverable hardware failure. This causes vSAN to set the health status for all disks in the group to Permanent disk loss, indicating disk failure.
Assuming all other disks have not suffered from a hardware failure, why would vSAN mark all disks in the group as failed?
A . The vSAN disk management service has failed.
B . The affected vSphere host is offline.
C . The key management server is offline.
D . Deduplication and compression are enabled on the vSAN cluster.
Answer: D
A vSAN administrator is designing a new all-flash vSAN cluster. The cluster will host read intensive applications.
Which factor should be included in the design to improve read performance?
A . Multiple disk groups
B . Large capacity disks
C . Large cache disks
D . Large controller cache
Answer: A
A vSAN 5-node cluster has two sets of VMs, each associated with a separate storage policy.
-Group A (Storage Policy: FTT=0)
– Group B (Storage Policy: FTT=2)
What are two possible results when two hosts in the vSAN cluster fail permanently? (Choose two.)
A. VMs in Group B will become inaccessible if a third host permanently fails.
B. vSAN will rebuild data associated with Group A.
C. VMs in Group A might experience data inaccessibility.
D. VMs in Goup B might experience data loss.
E. A host can be put into maintenance mode without impacting VMs in either Group A or B.
Answer: AC
Which storage policy action results in a component resync?
A . Enabling object checksum
B . Changing object space reservation to thick provisioning
C . Adding an IOPS Limit rule to a storage policy
D . Changing the failure tolerance method
Answer: D
An administrator has discovered that space utilized by VMs does not decrease after deleting files and folders within the VMs. The administrator needs to be able to reclaim this space.
Which action could the administrator perform to accomplish this task?
A . Enable Storage I/O Control.
B . Enable TRIM/UNMAP for the vSAN cluster.
C . Reboot the VM to recreate the swap file.
D . Assign a storage policy with thin provisioning.
Answer: D
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 elapse.
What is the health state of the objects?
A . Reduced availability with no rebuild
B . Reduced availability with no rebuild C delay timer
C . Non-availability related incompliance [non-compliance]
D . Reduced availability
Answer: A
End-users are complaining that an application running on an all-flash vSAN datastore is not performing well.
Which performance chart should an administrator view to troubleshoot this issue?
A . Recovery Write IOPS
B . Resync Latency
C . Read Cache Read IOPS
D . Write Buffer Free Percentage
Answer: B
Refer to the exhibit.
In a 2-node vSAN environment, a storage administrator has setup a vSAN storage policy.
When the stripe width is changed to three, what is the approximate component size of each replica marked in red?
A . 33GB
B . 50GB
C . 66GB
D . 100GB
Answer: A
An architect is asked to design a vSAN cluster with these requirements:
– Supports erasure coding storage policy
– Minimized inaccessibility from single device failures
– Ability to re-protect data after a failure
The desired configuration should be able to survive a single failure.
Which configuration satisfies the design requirements?
A . 3-node hybrid vSAN cluster
B . 4-node hybrid vSAN cluster
C . 4-node all-flash vSAN cluster
D . 5-node all-flash vSAN cluster
Answer: D
