Which two statements are true about Permanent Device Loss (PDL)? (Choose two.)
The correct answer is A. All paths are shown as Dead for the affected device. E. The operational state of the affected device changes to Lost Communication.. PDL occurs when a storage array signals a LUN is permanently inaccessible, causing all paths to go Dead and the device operational state to reflect loss of communication.
Question

Why each option
PDL occurs when a storage array signals a LUN is permanently inaccessible, causing all paths to go Dead and the device operational state to reflect loss of communication.
When PDL is triggered, the storage array sends SCSI sense codes confirming permanent unavailability, causing the ESXi host to mark every path to that device as Dead rather than simply as unavailable or degraded.
PDL is a storage-level failure triggered by SCSI sense codes from the array and is unrelated to datastore cluster configuration.
A yellow warning sign on a datastore indicates a non-critical issue such as a configuration inconsistency, not a PDL condition where the device is completely and permanently inaccessible.
The definitive PDL indicators in vSphere are Dead path state and the Lost Communication operational state change; a generic red error icon on the datastore view is not the specific diagnostic indicator for PDL.
Upon detecting PDL, the operational state of the affected storage device changes to reflect lost communication, which is the vSphere-level indicator that the device is no longer reachable at the storage layer.
