| An admin takes a vSphere snapshot of a VM and applies an OS update. After confirming the update the admin cannot enable Fault Tolerance on the VM and suspects there are snapshots that have not been consolidated. Which two operations can the administrator perform to verify consolidation needed? |
|
Definition
1. Expose the Needs Consolidation column in the virtual machines tab of the host
2. Browse the datastore containing the vmdk files and look for files with the "-delta.vmdk" extension |

| An admin finds that vMotion and Storage vMotion both do not work on a VM. The VM has been configured with N_Port ID Virtualization (NPIV). The VM has two data RDMs, one using a RAID 5 LUN and one using RAID 0+1 LUN. The mapping file for the RAID 5 LUN was created on the same datastore as the VM and the mapping file for the RAID0+1 LUN was placed in a datastore used for production data virtual disks. Why can vMotion and Storage vMotion not be used? |
|
Definition
Storage vMotion: S vMotion is not compatible with NPIV
vMotion: vMotion cannot be used unless both mapping files are placed on the same datastore |
