A storage administrator wants to add as asynchronous replication session to a pair of Unity systems with an
existing synchronous replication session that is operating correctly. Which configuration steps are needed?

A.
Create Replication interfaces on both systems.
Modify the Replication Connection Mode.
Run a Replication Connection Verify and Update operation.

B.
Create Replication Interfaces on the source system.
Modify the Mode for Replication Connection.
Perform a manual Sync operation on the Asynchronous session.

C.
Create Replication Interfaces on destination system.
Establish FC connectivity using the Synchronous FC Ports of each system.
Perform a manual Sync operation on the Asynchronous session.

D.
Create Replication Interfaces on both systems.
Establish FC connectivity using the Synchronous FC Ports of each system.
Run a Verify and Update operation for the Replication Connection

Explanation:
To fully configure asynchronous replication between systems, you must do each of following:
Configure connectivity for the replication interfaces used by asynchronous replication
– Configure the replication connection between systems
– Configure replication sessions between systems
Note: To fully configure synchronous replication, you must complete each of following:
Configure connectivity for the synchronous replication interfaces
Create the synchronous replication management ports
Configure the replication connection between systems
Configure replication sessions between systems
