NS0-157 Question #165: Real Exam Question with Answer & Explanation

Question

Options

• AIt can be in a Data ONTAP GX Cluster
• BIt must be on the same disk type as the source volume
• CIt can be smaller than the source volume
• DIt can be on a different disk type than the source volume

Explanation

SnapMirror DP destination volumes are flexible in their disk type, allowing storage tiering and cost optimization between source and destination.

Common mistakes.

• A. 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.
• B. 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.
• C. 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.
