NEW QUESTION 180
An administrator's Unity system is configured with both a Fibre Channel CNA and a Fibre Channel I/O module.
Which Fibre Channel port on each SP must be used for native synchronous replication?
- A. I/O module FC port 5
- B. CNA FC port 5
- C. CNA FC port 4
- D. I/O module FC port 2
Answer: C
Explanation:
Only one FC port can be configured and used for synchronous replication. Once an FC port is assigned, it will continue to act as the synchronous replication port and can never be changed. To determine the FC port used for synchronous replication, in the CLI console, run the command /remote/sys show -detail. Port information, similar to the following example, will appear in the output:
Synchronous FC ports = spb_fc4, spa_fc4

NEW QUESTION 183
A storage administrator is required to test a new version of an application loaded on a secondary host. The administrator must use existing data contained on a LUN provisioned from Unity to a primary host.
Which solution will meet the requirement and provide space efficiency?
- A. Create a snapshot of the LUN
Configure snapshot access to the LUN for the secondary host
Attach the snapshot to the secondary host - B. Create a Synchronous Replication session for the LUN
Configure access to the replica LUN for the secondary host
Attach the secondary host - C. Create an Asynchronous Replication on session for the LUN
Configure access to the replica LUN for the secondary host
Attach the secondary host - D. Create a snapshot of the LUN
Configure LUN access for the secondary host
Attach the snapshot to the secondary host
Answer: A
Explanation:
Explanation
Explanation/Reference:
Attaching a snapshot is only applicable for block snapshots, and makes the snapshot available for host IO. A host must have Snapshot access or LUN and Snapshot access configured in order to access the snapshot.
When a snapshot is attached, Unisphere provides the option to create a copy of the snapshot in case the administrator wants to preserve the current snapshot view for future use.

What is the minimum and maximum recovery point objectives (RPO) configurable when using Unity native
asynchronous replication?
- A. Minimum= 1 minuteMaximum= 24 hours
- B. Minimum= 5 minutesMaximum= 48 hours
- C. Minimum= 5 minutesMaximum= 24 hours
- D. Minimum= 1 minuteMaximum= 48 hours

Explanation
Recovery Point Objective (RPO) is an industry accepted term that indicates the acceptable amount of data,
measured in units of time, that may be lost in a failure. When you set up an asynchronous replication session,
you can configure automatic synchronization based on the RPO. You can specify an RPO from a minimum of
5 minutes up to a maximum of 1440 minutes (24 hours).
