An administrator arrives at work and begins their morning checks on a four node, all-flash vSAN Cluster. They notice the vSAN datastore reached 99% capacity due to a single node failure.
How can the administrator provide temporary relief?

  • A. change FTT=1 with RAID-5 (Erasure coding) to FTT=1 with RAID-1 (Mirroring)
  • B. change FTT=1 with RAID-1 (Mirroring) to FTT=1 with RAID-5 (Erasure coding)
  • C. change FTT=1 with RAID-1 (Mirroring) to FTT=0 No data redundancy
  • D. change FTT=1 with RAID-5 (Erasure coding) to FTT=0 No data redundancy

Answer : B

A company is using vSAN Data At Rest Encryption. vCenter is placed on a separate management cluster with external storage. The external storage system has suffered from a disk error and the vCenter Server restore from backup has been unsuccessful, due to media errors.
Considering the scenario, which statement is true?

  • A. All encrypted disk groups become unmounted and remain offline until vCenter Server is back online.
  • B. The data within the vSAN datastore is lost, if the hosts are powered off.
  • C. The VMs on the vSAN datastore need to be migrated to another datastore as quickly as possible to prevent data loss.
  • D. A new vCenter can be deployed using the existing KMS profile and associated with the existing vSAN encrypted clusters.

Answer : C

An architect has been asked to design a vSAN Stretched Cluster. The architect will configure Microsoft Active Directory to replicate between a server on Site A
(preferred) and a server on Site B (non-preferred). The architect must minimize the amount of raw storage capacity used.
Which storage policy needs to be applied to the Active Directory server on site A?

  • A. Dual site mirroring
  • B. None "" standard cluster
  • C. None "" stretched cluster
  • D. None "" keep data on Preferred

Answer : D

An administrator would like to put a vSAN host in an existing vSAN Cluster in maintenance mode. vMotion is configured and DRS is set to Fully Automated and all other advanced settings are their defaults.
The administrator uses this PowerCLI command:
Set-VMHost -VMHost "esxi-host01.corp.local" -State "Maintenance"
What is the default behavior?

  • A. Virtual machines will be live migrated and all storage objects residing on this host will migrate to another host that is not in maintenance mode.
  • B. Virtual machines will be live migrated to another host not in maintenance mode and storage objects will be migrated if it is required to be accessible.
  • C. Virtual machines will be live migrated to another host not in maintenance mode and storage objects will not migrate regardless of policy and state.
  • D. Virtual machines will not be live migrated to another host not in maintenance mode and storage objects will be migrated if it is required to be accessible.

Answer : A

A healthy vSAN Stretched Cluster has the existing vSAN Witness Host swapped for a new vSAN Witness Host using the "Change Witness Host" wizard.
If the administrator takes no further action, which two does the vSAN Health Check report show? (Choose two.)

  • A. Performance Service "" Stats DB Object "" object exists "" green
  • B. Performance Service "" Stats DB Object "" object health "" green
  • C. Data "" vSAN Object Health "" Reduced availability with no rebuild
  • D. Data "" vSAN Object Health "" Healthy
  • E. Performance Service "" Stats DB Object "" object health "" red

Answer : CE

Which two statements are true about a vSAN Cluster when the vCenter Server managing it is offline? (Choose two.)

  • B. vSAN continues to operate and all VMs inherit the default vSAN storage policy.
  • C. Use a Web browser to monitor vSAN through the vSphere Host Client.
  • D. Manage and view vSAN health information using RVC commands.
  • E. vSAN continues to operate, but vSAN performance metrics will be lost.

Answer : DE

Refer to the exhibit.

There are three hosts in a vSAN cluster. All virtual machines in the cluster are assigned a storage policy with failures to tolerate set to 1 failure "" RAID-1
What is the result of placing a host in maintenance mode using the options shown in the image?

  • A. The host will enter maintenance mode. A reduced redundancy warning is displayed.
  • B. The host will not enter maintenance mode. The administrator is prompted to select a different data migration option.
  • C. The host will not enter maintenance mode. A general vSAN error is reported.
  • D. The host will enter maintenance mode. All powered-off and suspended VMs are migrated to other hosts.

Answer : B

Objects created on a stretched vSAN Cluster are deployed with the vSAN default storage policy assigned.
Where is the data protected?

  • A. only across both sites
  • B. within and across both sites
  • C. only within the non-preferred site
  • D. only within the preferred site

Answer : A
