Which of the following is true about a data protection (DP) mirror destination volume? (Choose all that apply)
The correct answer is A. Can be in the same vserver as the source B. Can be in a different vserver as the source C. Can be on a different cluster from the source. A DP mirror destination volume in clustered Data ONTAP can reside in the same or different SVM and on a remote cluster, but must be on a clustered ONTAP system and must be at least as large as the source.

Why each option
A DP mirror destination volume in clustered Data ONTAP can reside in the same or different SVM and on a remote cluster, but must be on a clustered ONTAP system and must be at least as large as the source.
A DP mirror destination can reside in the same SVM as the source, which is a supported intra-SVM SnapMirror configuration in clustered Data ONTAP.
A DP mirror destination can reside in a different SVM than the source, enabling inter-SVM SnapMirror relationships within or across clusters.
A DP mirror destination can be placed on a different cluster, which is the primary disaster recovery use case for SnapMirror in clustered Data ONTAP.
A clustered Data ONTAP DP mirror destination must be a clustered ONTAP volume; 7-mode systems cannot serve as a destination for a standard clustered DP mirror relationship.
The DP mirror destination volume must be equal to or larger than the source; a smaller destination cannot store all data blocks transferred from the source.
