Which statement is true about a Data Protection (DP) - type SnapMirror destination volume?
The correct answer is D. It can be on a different disk type than the source volume. SnapMirror DP destination volumes are flexible in their disk type, allowing storage tiering and cost optimization between source and destination.

Why each option
SnapMirror DP destination volumes are flexible in their disk type, allowing storage tiering and cost optimization between source and destination.
DP SnapMirror destination volumes are not specific to Data ONTAP GX Cluster; GX was a scale-out platform with its own replication considerations and is not a defining characteristic of DP destination placement.
The destination volume is not required to match the source disk type; this restriction does not exist for DP SnapMirror relationships, which is one of its key operational flexibilities.
A DP destination volume must be equal to or larger than the source volume in size, not smaller, to ensure all source data can be replicated without truncation.
A DP-type SnapMirror destination volume can reside on a different disk type than the source volume. This is by design to allow administrators to replicate data to lower-cost or different-tier storage, such as replicating from SAS source disks to SATA destination disks, enabling cost-effective disaster recovery or archiving strategies.
