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?

Question

Options

• AIt will fail with an alert. Primary level of failures to tolerate=3 is not supported with mirroring.
• BIt will fail with an alert. The policy of a running VM cannot be dynamically changed.
• CvSAN will try to create an additional mirror of the VM's disk components, as long as there is a
• DvSAN will switch its failure to tolerate method for any VMs with that policy, to optimize for space.

• A
  3% (2)
• B
  8% (5)
• C
  73% (47)
• D
  16% (10)

Explanation

Incorrect Answers: D: RAID 5 or RAID 6 erasure coding does not support a Primary level of failures to tolerate value Note: Primary level of failures to tolerate Defines the number of host and device failures that a virtual machine object can tolerate. For n failures tolerated, each piece of data written is stored in n+1 places, including parity copies if using RAID 5 or RAID 6. When provisioning a virtual machine, if you do not choose a storage policy, vSAN assigns this policy as the default virtual machine storage policy. If fault domains are configured, 2n+1 fault domains with hosts contributing capacity are required. A host, which is not part of any fault domain is considered its own single-host fault domain. Default value is 1. Maximum value is 3. https://docs.vmware.com/en/VMware-vSphere/6.5/com.vmware.vsphere.virtualsan.doc/GUID- 08911FD3-2462-4C1C-AE81-0D4DBC8F7990.html
