6. Question 6 · 1

   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?

   Choose one answer.

   • The vSAN disk management service has failed.
   • The affected vSphere host is offline.
   • The key management server is offline.
   • Deduplication and compression are enabled on the vSAN cluster.

   Choose one answer.

   • Enabling object checksum
   • Changing object space reservation to thick provisioning
   • Adding an IOPS Limit rule to a storage policy
   • Changing the failure tolerance method

8. Question 8 · 1

   Choose one answer.

   • Enable LACP on vSAN switch ports.
   • Upgrade vCenter and vSAN nodes to vSAN 6.6 or later.
   • Enable unicast on the vSAN interfaces.
   • Disable multicast for vSAN using ESXCLI commands.

9. Question 9 · 1

   • 4-node hybrid vSAN cluster
   • 4-node all-flash vSAN cluster
   • 5-node all-flash vSAN cluster

    • 50GB
    • 66GB
    • 100GB

11. Question 11 · 1

    A host in a vSAN cluster has the following VMware Compatibility Guide approved disks: -3 solid state devices (SSD) used for cache -12 magnetic drivers (HDD) used for capacity Which two options are valid disk group configurations? (Choose two.)

    Choose all answers that apply.

    • 1 Disk Group with 2 SSD and 6 HDD
    • 1 Disk Group with 3 SSD and 12 HDD
    • 2 Disk Groups with 1 SSD and 6 HDD each
    • 3 Disk Groups with 1 SSD and 4 HDD each
    • 4 Disk Groups with 3 HDD each

12. Question 12 · 1
