A Volume Snap Mirror from a 64-bit source to a 32-bit destination will fail when which condition is enabled on the 64-bit source?

A Volume Snap Mirror from a 64-bit source to a 32-bit destination will fail when which condition is enabled on the 64-bit source?

• A. Volume Guaranteed disabled
• B. Compression enabled
• C. FlexShare enabled
• D. ASIS enabled

Answer: (B)

Compression on the 64‑bit source changes how data is stored and addressed, producing compressed blocks that the destination must interpret exactly. A 32‑bit destination uses a different block addressing and metadata scheme, so it cannot reliably map or reconstruct the compressed blocks coming from a 64‑bit source. That mismatch breaks the Volume SnapMirror relationship, causing the transfer to fail. The other settings aren’t tied to this cross‑bit mirroring problem. Volume Guarantee, FlexShare, and ASIS don’t introduce the same fundamental incompatibility between a compressed 64‑bit source and a 32‑bit destination, so they don’t inherently cause the mirror to fail.
