Remote replication is optimized for which three use cases?
A.
Replication can be used to distribute data (such as virtual machine images or media) to remote
systems across the world.
B.
Replication can be used to migrate data and configuration when upgrading hardware.
C.
Replication can be configured from an appliance to itself or its cluster peer for redundancy.
D.
Replication can be used to mirror an appliance for disaster recovery
Explanation:
Remote replication (or just “replication”) is ageneral-purpose feature optimized for
the following use cases:
* Data distribution (A)
Replication can be used to distribute data (such as virtual machine
images or media) to remote systems across the world in situations where clients of the target
appliance wouldn’t ordinarily be able to reach the source appliance directly, or such a setup
would have prohibitively high latency. One example uses this scheme for local caching to
improve latency of read-only data (like documents).
* Data migration (B)
Replication can be used to migrate data and configuration between 7000
series appliances when upgrading hardware or rebalancing storage. Shadow migration can
also be used for this purpose.
*Disaster recovery(D)
Replication can be used to mirror an appliance for disaster recovery.
