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

Correct Answer: A

Explanation/Reference:
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

A storage administrator is creating a host profile in Unisphere to provide host access to block storage
resources using the iSCSI protocol. The host initiators were not automatically discovered and must be
manually added.
In addition to the SAN host IQN, what other configuration can be performed through the "Create iSCSI
Initiator Wizard" window?

• A.Enable and disable CHAP settings
• B.Create Mutual CHAP secret
• C.Create Global CHAP secret
• D.Enter CHAP username and secret

Correct Answer: D

Explanation/Reference:
A sample from a Broadcomm BIOS is provided in the figure below, illustrating the IQN assignment for the
VNX iSCSI target.
