Which two solutions require Physical Mode Raw Device Mapping (RDM)? (Choose two.) A-) Note: RDM is not available for direct-attached block devices or certain RAID devices. You cannot map a disk partition as RDM. RDMs require the mapped device to be a whole LUN.(storage array device)D-) Guest Clustering—– Physical mode is useful while running SAN management agents or other SCSI target-based software in the virtual machine.Physical mode also allows virtual-to-physical clustering for cost-effective high availability.Virtual Machine Snapshots are not available when the RDM is used in physical compatibility mode.You can use this mode for Physical-to-virtual clustering and cluster-across-boxes.VMFS5 supports greater than 2 TB disk size for RDMs in physical compatibility mode only. These restrictions apply:You cannot relocate larger than 2 TB RDMs to datastores other than VMFS5.You cannot convert larger than 2 TB RDMs to virtual disks, or perform other operations that involve RDM to virtual disk conversion. Such operations include cloning.FAQ: https://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1037959
