A system administrator wants to configure asynchronous replication on their Unity system. What is required
before creating a replication session?

A.
A Fibre Channel connection configured between the remote systems.
A configured replication connection between the remote systems.

B.
A Sync Replication Management Port configured on each system.
A Fibre Channel connection configured between the remote systems.
A configured replication connection between the remote systems.

C.
An IP-based replication interface on the same network as the destination system’s replication interface.
A configured replication connection between the remote systems.

D.
A Sync Replication Management Port configured on each system.
An IP-based replication interface on the same network as the destination system’s interface.
A configured replication connection between the remote systems.

Explanation:
Asynchronous remote replication requires a replication interface be created on each SP on the system.
For asynchronous replication, replication is performed over Ethernet interfaces configured on the system. On
EMC Unity physical systems, the onboard 10GbE BaseT ports, CNA ports with Ethernet personality, or Ethernet
ports located on I/O modules can be used for replication. In UnityVSA systems, any I/O port can be used for
asynchronous replication.
