問題文
Two metro arrays already run a stretched pod for zero data loss. The business now also wants a copy at a third site several hundred kilometers away for regional events. What can be done with the existing design?
選択肢
- Unstretch the pod and rebuild the whole design around continuous asynchronous replication to both of the two remote sites instead.
- Place a protection group inside the stretched pod and replicate that group asynchronously to the array at the third site.
- Add the third array to the same pod so that all three systems hold a synchronous copy of the volumes in that single pod at once.
- Export the volumes of the pod to an offload target and let the third site read them back whenever a regional event has been declared.
